Description
FIELD OF THE INVENTION

The present disclosure relates to fragrance premix compositions that include a silicone polymer, an aminofunctional material, and a fragrance material that includes aldehyde and/or ketone moieties, where the components are reasonably miscible. The present disclosure also relates to consumer product compositions that include such premixes. The present disclosure also relates to related methods of making and using such premixes and products.


BACKGROUND OF THE INVENTION

Manufacturers of consumer products, such as fabric care compositions, desire efficient ways to deliver perfume materials to their products, and perhaps more importantly to a consumer's target surface upon treatment with the consumer product. For example, if a consumer product is used to treat a fabric during a laundering operation, it is vastly preferred that the perfume materials deposit onto the fabric rather than be washed down the drain.


Perfume raw materials (“PRMs”) can be co-mixed with silicones, and deposition efficiency may be improved; however, there is further room for improvement. Aminosilicones may be used in such mixtures with certain PRMs, and deposition efficiency may further increase due to interactions between the amine groups of the aminosilicone and the PRMs.


However, the loading capacity and/or number of interactions may be limited by the number of amino groups on the silicone. Furthermore, it is not necessarily a simple matter of increasing the amine content of the aminosilicone, as this would tend to increase solubility of the aminosilicone, thus reducing its tendency to be easily emulsified in water and/or deposit onto a fabric. Additionally, if the aminosilicone is too hydrophilic, it is believed that certain PRMs, many of which are relatively hydrophobic, will not partition into the silicone droplets and therefore will not be adequately associated with the silicone polymer, resulting in suboptimal perfume deposition upon usage.


Other amine-containing (non-silicone) compounds are known to be useful for perfume delivery purposes, but such compounds tend to lead to undesirable discoloration of perfume premixes and/or final products.


There is a need for improved fragrance premix compositions, related consumer product compositions, and/or related methods that addresses one or more of the above problems.


SUMMARY OF THE INVENTION

The present disclosure relates to fragrance premix compositions and related consumer products.


For example, the present disclosure relates to a fragrance premix composition that includes: a silicone polymer, where the silicone polymer is characterized by at least one of the following: (a) an Extraction Percentage (Extr. %) of less than less than 8, after 24 hours, and/or (b) a solubility in water of less than about 1000 mg/L, measured at 21° C., and/or (c) an amine content of from 0.0 to about 2.2; an aminofunctional material, where the aminofunctional material is characterized by a molecular weight of less than about 1000 Daltons, and where the aminofunctional material includes at least one amine moiety selected from a primary amine moiety, a secondary amine moiety, or a combination thereof; and a fragrance material that includes one or more perfume raw materials, where the one or more perfume raw materials comprises an aldehyde moiety, a ketone moiety, or combinations thereof; where a mixture of the silicone polymer, the aminofunctional material, and the one or more perfume materials is 20 reasonably miscible, for example when in a 9.9:0.1:0.1 weight ratio being characterized by a Percent Transmittance (% T) of at least 40 at 480 nm. The present disclosure further relates to methods of making such fragrance premix compositions.


The present disclosure also relates to consumer product compositions that include such fragrance premix compositions, consumer product compositions that contain droplets that include the components of the premix compositions, and methods of making and using such consumer product compositions.







DETAILED DESCRIPTION OF THE INVENTION

The present disclosure relates to fragrance premix compositions and related consumer products and methods. The fragrance premix compositions include a silicone polymer, an aminofunctional material, and a fragrance material that comprises certain perfume raw materials. Each of these materials is selected for certain characteristics and compatibilities, as described in more detail below. For example, the silicone polymer may be characterized by certain solubility in water, the aminofunctional material may have be characterized by a relatively low molecular weight, and the PRMs may comprise certain functional groups. Furthermore, the three components may be relatively miscible with each other. Failure to make the proper selections on one or more of the components may result in less efficient premixes or consumer products (e.g., as evidenced by decreased perfume performance).


Without being bound by theory, it is believed that by de-coupling the amine groups from the silicone polymer, at least in part, the loading efficiency of the PRMs in the droplets can be increased while maintaining the relative hydrophobicity of the silicone, thereby allowing an emulsion to be conveniently made and/or enabling deposition to more efficiently occur.


Additionally, it has been found that pairing the aminofunctional material with the silicone polymer can lead to improved color stability in the premixes and/or final products. Without wishing to be bound by theory, it is believed that at least some of the aminofunctional material may partition into the silicone droplets, and the amine groups may thereby be “protected” from discoloring side reactions.


The components, premixes, compositions, and methods are described in more detail below.


As used herein, the articles “a” and “an” when used in a claim, are understood to mean one or more of what is claimed or described. As used herein, the terms “include,” “includes,” and “including” are meant to be non-limiting. The compositions of the present disclosure can comprise, consist essentially of, or consist of, the components of the present disclosure.


The terms “substantially free of” or “substantially free from” may be used herein. This means that the indicated material is at the very minimum not deliberately added to the composition to form part of it, or, preferably, is not present at analytically detectable levels. It is meant to include compositions whereby the indicated material is present only as an impurity in one of the other materials deliberately included.

Fragrance Premix Compositions


The present disclosure relates to fragrance premix compositions. The fragrance premix compositions of the present disclosure may be useful components of consumer product compositions and may help to improve perfume delivery and performance of those consumer product compositions compared to products where such a premix is not used. Further, it is believed that combining the ingredients in a premix provide more efficient perfume delivery and performance in a consumer product compared to if the ingredients are added separately (e.g., not as a premix) to the consumer product, particularly in aqueous consumer products.


The fragrance premix compositions comprise a silicone polymer, an aminofunctional material, and a fragrance material, each of which is described in more detail below. The components should be selected based on a variety of characteristics. Failure to make the proper selections may lead to suboptimal premix compositions.


The silicone polymer, the aminofunctional material, and the fragrance material should be reasonably miscible with each other as a ternary system (silicone polymer, aminofunctional material, fragrance material). If the components are not reasonably miscible, then they may not associate with each other and/or may not form droplets that comprise all three components in an emulsion or in a consumer product composition. It is desirable that such droplets form to facilitate what is believed to be the most efficient perfume delivery system.


To determine whether the three selected components are reasonably miscible, they may be mixed together and visually inspected; if a mixture of 9.9 parts (by weight) silicone polymer, 0.1 part aminofunctional material, and 0.1 part fragrance material is mixed with a vortex mixer, water (if any) is removed, and then the mixture is visually inspected, the components may be considered miscible if the mixture appears transparent. Additionally or alternatively, to determine whether the three selected components are reasonably miscible, they may be mixed together and analyzed for percent transmittance. More specifically, a mixture of 9.9 parts (by weight) silicone polymer, 0.1 part aminofunctional material, and 0.1 part fragrance material may be provided, mixed with a vortex mixer, and then analyzed for percent transmittance (% T) at 480 nm. More details for such measurements are provided in the Test Methods section below. The % T of the ternary system at 480 nm may be at least 40, or at least 50, or at least 60, or at least 75, or at least 80, or at least 85, or at least 90, or at least 95, or at least 98. Greater values of % T correlate with greater transparency of the mixture, indicating greater degrees of miscibility.


The silicone polymer and the aminofunctional material may be reasonably miscible in the absence of the fragrance material. A mixture of 9.9 parts (by weight) silicone polymer and 0.1 part aminofunctional material (i.e., a binary system) may be provided, mixed with a vortex mixer, and then analyzed for percent transmittance (% T) at 480 nm according to the test method provided below. The % T of this binary system at 480 nm may be at least 40, or at least 50, or at least 60, or at least 75, or at least 80, or at least 85, or at least 90, or at least 95, or at least 98. Greater values of % T correlate with greater transparency of the mixture, indicating greater degrees of miscibility.


The fragrance premix composition is a liquid. The premix may be characterized by a viscosity, for example from about 10 to about 10000 Pa·s, preferably from about 10 to about 5000 Pa·s, preferably from about 10 to about 1000 Pa·s, preferably from about 10 to about 500 Pa·s, preferably from about 20 to about 400 Pa·s, more preferably from about 25 to about 300 Pa·s, even more preferably from about 100 to about 300 Pa·s, measured at 0.1 rad/s and 25° C. Obtaining a fragrance premix composition with the target viscosity may be desirable for processability reasons, particularly as premixes having a very high viscosity may be difficult to formulate into a product.


The fragrance premix composition may be substantially free of water. The premix composition may comprise less than 10%, or less than 5%, or less than 2%, or less than 1%, or less than 0.5%, or less than 0.1%, or even comprise 0%, by weight of the premix composition of water. Such low-water premixes may be desirable, for examples, when the premix will be formulated into a low-water consumer product, such as a solid composition or a composition encapsulated by water-soluble film. In such cases, the silicone polymer may be a fluid that is the bulk of the premix.


The fragrance premix composition may comprise water. The fragrance premix composition may comprise from about 1% to about 90%, or from about 1% to about 75%, or from about 1% to about 60%, or from about 1% to about 50%, or from about 5% to about 50%, or from about 10% to about 50%, or from about 25% to about 50%, by weight of the composition, of water. The presence of water may facilitate the formation of droplets, in view of the silicone polymer being relatively hydrophobic, which can facilitate more convenient dispersion of the premix in a consumer product.


The fragrance premix composition may be in the form of an emulsion. The emulsion may preferably be an oil-in-water emulsion. The emulsion may comprise a plurality of droplets, preferably where the plurality of droplets are characterized by a mean diameter of from about 1 micron to about 10 microns, preferably from about 1 micron to about 5 microns. Without wishing to be bound by theory, it is believed that droplets of a certain minimum size are desired for efficiency of deposition onto the target surface, but that droplets that exceed a certain size can create performance and/or stability issues, such spotting on the target surface.


The fragrance premix composition may comprise one or more emulsifiers. As used herein, “emulsifier(s)” and “emulsifying agent(s)” are used interchangeably. Selection of proper emulsifier can facilitate the formation of droplets of the desired size, and/or the stable incorporation of the premix into a final product. Emulsifiers may also be selected so as to not have an undesirable impact on viscosity of the emulsion, for example by increasing the viscosity to an undesirable level.


The one or more emulsifiers may comprise a nonionic surfactant. Suitable nonionic surfactant may include alkoxylated fatty alcohols. The nonionic surfactant may be selected from ethoxylated alcohols and ethoxylated alkyl phenols of the formula R(OC2H4),OH, wherein R is selected from the group consisting of aliphatic hydrocarbon radicals containing from about 8 to about 15 carbon atoms and alkyl phenyl radicals in which the alkyl groups contain from about 8 to about 12 carbon atoms, and the average value of n is from about 5 to about 15.


The one or more emulsifiers may comprise linear emulsifiers, branched emulsifiers, or mixtures thereof, preferably linear nonionic surfactants, branched nonionic surfactants, or mixtures thereof. In particular, linear emulsifiers may be useful for emulsifying the fragrance materials, and branched emulsifiers may be useful for emulsifying the silicone polymer, particularly aminofunctional silicone polymers.


The one or more emulsifiers may be substantially hydrophobic. The one or more emulsifiers may be characterized by an HLB value of from about 5 to about 20, or from about 8 to about 16. The HLB value of a nonionic surfactant may be determined according to the method provided below.


The silicone polymer, the aminofunctional material, and the fragrance material are described in more detail below.


Silicone Polymer


The fragrance premix compositions of the present disclosure comprise a silicone polymer (or simply “silicone” as used herein). Without wishing to be bound by theory, it is believed that the hydrophobic nature of the silicone polymer facilitates effective deposition of the fragrance materials onto a target surface, such as a fabric during a laundering operation.


The fragrance premix composition may comprise from about 30% to about 98%, or from about 40% to about 95%, or from about 50% to about 90%, or from about 60% to about 85%, by weight of the fragrance premix composition, of the silicone polymer.


The silicone polymer may be relatively hydrophobic. Relatively hydrophobic silicones may be emulsified in water, in a premix, and/or in a consumer product composition and form droplets in the composition. This can enable partitioning of the aminofunctional material and the fragrance material into the droplet so that the components of the ternary system are associated with each other, resulting in efficient perfume deposition and performance in end use, as well as improved color stability. On the other hand, if the silicone is too hydrophilic or too soluble in water, it may not facilitate effective partitioning or perfume delivery.


The silicone polymer may have a relatively low solubility in water. The silicone polymer may be characterized by a solubility in water of less than about 1000 mg/L (e.g., less than about 1000 mg silicone solubilizing in 1 L of water), or less than about 750 mg/L, or less than about 500 mg/L, or less than about 250 mg/L, or less than about 150 mg/L, or less than about 100 mg/L, measured at 25° C.


The silicone polymer may be characterized by its Extraction Percentage (“Extr. %”). The Extraction Percentage of a silicone polymer relates to how much (typically reported as a weight %) of an initial polymer sample that is combined with DI water can be found in the water after a certain time period. Thus, relatively low Extr. % values indicate a relatively low degree of water solubility. As described above, it may be preferred that the silicone polymers of the present disclosure are characterized by relatively low water solubility, and so it follows that relatively low Extr. % values may also be preferred. For example, the silicone polymers of the present disclosure may be characterized by an Extr. % value of less than 8%, or less than 5%, or less than 4%, or less than 2%, or less than 1%, or less than 0.5%, or even less than 0.1%, after 24 hours. The silicone polymers of the present disclosure may be characterized by an Extr. % value of less than 15%, or less than 10%, or less than 5%, or less than 3%, or less than 2%, or less than 1.5%, after six days. Extraction Percentage is determined according to the method provided in the Test Methods section below.


The molecular weight of the silicone is usually indicated by the reference to the viscosity of the material. The silicones may comprise a viscosity of from about 10 to about 2,000,000 centistokes at 25° C. Suitable silicones may have a viscosity of from about 50 to about 200,000 centistokes, or from about 100 to about 100,000 centistokes, or from about 500 to about 60,000 centistokes, or from about 1000 to about 50,000 centistokes, or from about 1000 to about 10,000 centistokes, at 25° C. Relatively higher molecular weights and/or viscosities of the silicone may be preferred, as such silicones may be relatively hydrophobic.


It is preferred that the silicone polymer is be a fluid at room temperature (e.g., 22° C.) so that effective partitioning and droplet formation can conveniently occur.


Suitable silicones may be linear, branched, or cross-linked. The silicones may comprise silicone resins. Silicone resins are highly cross-linked polymeric siloxane systems. The cross-linking may be introduced through the incorporation of trifunctional and tetrafunctional silanes with monofunctional or difunctional silanes, or both, during manufacture of the silicone resin.


Suitable silicones may include non-functionalized siloxane polymers, functionalized siloxane polymers, or combinations thereof. The silicone may comprise a non-functionalized siloxane polymer. (By non-functionalized, it is meant that functional groups, if present, are generally non-reactive—for example, methyl groups.) The siloxane polymer may comprise polyalkyl and/or phenyl silicone fluids, resins, and/or gums.


The silicone polymer may comprise an aminosilicone, silicone polyether, polydimethylsiloxane (PDMS), cationic silicones, silicone polyurethane, silicone polyureas, or mixtures thereof. The silicone polymer may preferably be selected from a polydimethylsiloxane (PDMS) polymer, an aminosilicone, or a mixture thereof.


The silicone polymer may comprise a cyclic silicone. The cyclic silicone may comprise a cyclomethicone of the formula [(CH3)2SiO]n where n is an integer that may range from about 3 to about 7, preferably from about 5 to about 6.


The silicone polymer may include at least one methyl group on at least some silicone atoms, or at least two methyl groups on at least some silicone atoms. The silicone polymer may comprise

moieties; such polymers may further comprise additional functional moieties, such as aminofunctional moieties, or such polymers may be free of additional functional moieties. The silicone polymer may be a polydimethylsiloxane (PDMS).


The siloxane polymer may have an empirical structure according to Formula (I) below:

[R1R2R3SiO1/2]n[R4R4SiO2/2]m[R4SiO3/2]j  Formula (I)

wherein:


i) each R1, R2, R3 and R4 may be independently selected from the group consisting of H, —OH, C1-C20 alkyl moieties, C1-C20 substituted alkyl moieties, C6-C20 aryl moieties, C6-C20 substituted aryl moieties, alkylaryl moieties, and/or C1-C20 alkoxy moieties;


ii) n may be an integer from about 2 to about 10, or from about 2 to about 6; or 2; and selected that n=j+2;


iii) m may be an integer from about 5 to about 8,000, from about 7 to about 8,000 or from about 15 to about 4,000; and


iv) j may be an integer from 0 to about 10, or from 0 to about 4, or 0.


In the silicone polymer according to Formula (I), the R2, R3 and R4 groups may independently comprise methyl, ethyl, propyl, C4-C20 alkyl, and/or C6-C20 aryl moieties. Each of R2, R3 and R4 may be methyl. Each R1 moiety blocking the ends of the silicone chain may comprise a moiety selected from the group consisting of hydrogen, methyl, methoxy, ethoxy, hydroxy, propoxy and/or alkoxy.


Non-limiting examples of such silicones are polydimethylsiloxanes (used interchangeably herein with “polydimethylsilicone” or “PDMS” or “dimethicone”), such as Xiameter PMX 200 fluid available from Dow Chemicals (Midland Mich.), and/or silanol terminated silicones (also called dimethiconol) such as DMS-S31, DMS-S32 and DMS-S42, all available from Gelest Inc. (Morrisville, Pa.).


The silicone polymer may be a homopolymer or a copolymer comprising one or more of the following repeat units: diphenylsiloxane, phenylmethylsiloxane, alkylarylsiloxane, 2-phenylpropylmethyl siloxane, ethylmethylsiloxane, propylmethylsiloxane, butylmethylsiloxane, octylmethylsiloxane, dodecylmethylsiloxane, tetradecylmethylsiloxane, hexadecylmethylsiloxane, octadecylmethylsiloxane, or mixtures thereof.


Examples of such polymers are: PDM-1922, PDM-0821 PMM-1043, PMM-1025, PMM 0021, APT-133, APT-213, APT-263, ALT-143, Alt-281, DMA-021 (all available from Gelest Inc, Morrisville, Pa.), and/or Silwax 3H12-MS, Silwax3H-MS, and Silwax-L118 (all available from Siltech Corporation, Toronto, Canada).


The silicone may comprise a functionalized siloxane polymer. Functionalized siloxane polymers may comprise one or more functional moieties selected from the group consisting of amino, amido, alkoxy, hydroxy, carbinol, polyether, carboxy, hydride, mercapto, sulfate, phosphate, and/or quaternary ammonium moieties. These moieties nay be attached directly to the siloxane backbone through a bivalent alkylene radical (i.e., “pendant”), or may be part of the backbone. Suitable functionalized siloxane polymers include materials selected from the group consisting of aminosilicones, amidosilicones, silicone polyethers, silicone-urethane polymers, quaternary ABn silicones, amino ABn silicones, and combinations thereof.


The silicone polymer may comprise an aminosilicone (also disclosed herein as, and used interchangeably with, an “aminofunctional silicone”). Aminosilicones may be preferred, as such silicone polymers provide additional amine groups for further fragrance loading, thereby providing a more efficient fragrance delivery system. Suitable silicone polymers may preferably include amine groups but no other hydrophilic functional groups, such as carboxy or hydroxy groups, as such functional groups may undesirably increase the water solubility of the silicone polymers without offering suitable fragrance loading sites for aldehyde- or ketone-containing PRMs.


Suitable aminosilicones may have an empirical structure according to Formula (II):

[R1R2R3SiO1/2](j+2)[(R4Si(X—Z)O2/2]k[R4R4SiO2/2]m[R4SiO3/2]j  Formula (II),

wherein:


R1, R2, R3 and R4 are each independently selected from —H, —OH, C1-C20 alkyl, C1-C20 substituted alkyl, C6-C20 aryl, C6-C20 substituted aryl, alkylaryl, C1-C20 alkoxy and combinations thereof, with the proviso that R1 may also be selected from X—Z in addition to the other groups mentioned;


X is a divalent alkylene radical comprising from 2 to 12 carbon atoms, and/or is independently selected from the group consisting of —(CH2)s—, —CH2—CH(OH)—CH2—,

and mixtures thereof, wherein s is on average from about 2 to about 10;


Z is independently selected from the group consisting of




embedded image



wherein R5 is selected from —H, C1-C20 alkyl, C1-C20 substituted alkyl, and combinations thereof, such that at least one R5 on each nitrogen is a hydrogen atom;


k is on average from about 3 to about 40;


m is on average from about 100 to about 2,000; and


j is on average from about 0 to about 10.


In a preferred silicone polymer according to Formula (II), R1, R2, R3 and R4 are all —CH3 groups, and j=0.


It may be preferred that the silicone polymer comprises silicones according to the following structures:




embedded image



or mixtures thereof, where k and m are defined as above with regard to Formula (II). Such silicone polymers are believed to be particularly useful in the fragrance premixes of the present disclosure.


The aminofunctional silicone may be characterized by one or more amine content values. The amine content, namely the primary, secondary, tertiary, and/or total amine values (meq/g), is defined as the milliequivalents of amine functionality (primary, secondary, tertiary, and/or total) present in one gram of a sample. Without wishing to be bound by theory, it is believed that the amine content of the amino functional silicone contributes, at least in part, to the solubility in water of the amino functional silicone. For example, as amine content increases, the amino functional silicone is generally more soluble in water. Therefore, it may be desirable to limit the nitrogen content of the amino functional silicone in order to maintain a relatively low solubility, thereby facilitating portioning of the perfume materials out of the aqueous phase of the emulsion.


The amino functional silicone may be characterized by a total amine content of from about 0.05 to about 2.2, preferably from about 0.1 to about 2.14, or from about 0.071 to about 1.78, or from about 0.71 to about 1.43, or from about 0.14 to about 1.07, or from about 0.14 to about 0.71, or from about 0.21 to about 0.71, or from about 0.36 to about 0.71. The amino functional silicone may be characterized by a primary amine content of from about 0.05 to about 2.2, preferably from about 0.071 to about 2.14, or from about 0.071 to about 1.78, or from about 0.71 to about 1.43, or from about 0.14 to about 1.07, or from about 0.14 to about 0.71, or from about 0.21 to about 0.71, or from about 0.36 to about 0.71. The amino functional silicone may characterized by a ratio of primary amine content to total amine content of from about 1:2 (e.g., 50%) to about 2:2 (e.g., 100%), or from about 1.2:2, or from about 1.5:2, or from about 1.8:2. It may be preferred to select an amino functional silicone having a relatively high proportion of primary amines compared to total amines to improve the PRM loading efficiency, given that on fabric it is believed that the PRM residues be associated with, or may even have reacted with, primary amines.


The amino functional silicone may be characterized by a weight percentage of nitrogen. For example, the amino functional silicone may be characterized by a nitrogen content of from about 0.1% to about 4%, or from about 0.1% to about 3%, or from about 0.1% to about 2%, or from about 0.2% to about 1.5%, or from about 0.2% to about 1.0%, or from about 0.3% to about 0.8%, or from about 0.3% to about 0.75%, reported as functional group equivalent weight %. The functional group equivalent weight percentage can be determined from the amine values of the amino functional silicone, as described in more detail in the Test Methods section. The silicone polymer may be free of nitrogens, in which case its nitrogen content may be 0.0%; therefore, suitable silicones may be characterized by a nitrogen content of from 0.0% to about 4%.


Exemplary commercially available aminosilicones include: Xiameter 8566, Xiameter 8822, available from Dow Performance Silicones; KF-873, KF-861, KF-867, KF-8003, available from Shin-Etsu Silicones of North America, Akron, Ohio; and Magnasoft Plus and SF-1708, available from Momentive Performance Materials, Tarrytown, N.Y.


Aminofunctional Material


The fragrance premix compositions of the present disclosure comprise an aminofunctional material. It is believed that the aminofunctional material associates with the perfume raw materials described herein and facilitate the deposition and release of the perfume when used, for example in a consumer product. Furthermore, it is believed that when the aminofunctional material can adequately associate with the silicone polymer, deposition and color stability benefits can further be achieved.


The fragrance premix composition may comprise from about 1% to about 20%, or from about 2% to about 15%, or from about 3% to about 12%, or from about 4% to about 10%, or from about 5% to about 10%, by weight of the fragrance premix composition, of the aminofunctional material.


The amino functional material may be characterized by a relatively low molecular weight. Relatively low molecular weights may be preferred for mass efficiency reasons (e.g. a favorable/high ratio of amine groups to molecular weight). For example, the aminofunctional material may be characterized by a molecular weight of about 40 to about 1000 Daltons, preferably from about 50 to 800 Daltons, more preferably from about 60 to about 600 Daltons, even more preferably from about 60 to about 500 Daltons.


The aminofunctional material may comprise one, two, or three amine moieties per molecule, preferably one or two amine moieties. The amine moiety may be selected from the group consisting of a primary amine moiety, a secondary amine moiety, or a combination thereof. It is believed that primary and/or secondary amine moieties may better associate with the PRMs compared to tertiary and/or quaternary amine moieties. Furthermore, two or even three amine moieties may provide improved association/loading in combination with the perfume raw materials, compared to compounds having only one amine group. However, as described in more detail below, there may be a desire to limit the number of amine groups.


In general, the greater the number of amine moieties, the greater the solubility of the compound in water. It is believed that if the material is too water-soluble/hydrophilic, it may not be adequately miscible with the silicone, which is generally hydrophobic. One way to quantify the amine content of the molecule is the Amine Equivalent Weight of the molecule. For the sake of the present disclosure, the Amine Equivalent Weight is defined as the molecular weight of aminofunctional material divided by the sum of the number of primary amine groups and the number of secondary amine groups per molecule. This is represented below as an equation:

The aminofunctional material may have an Amine Equivalent Weight of about 25 to 300, preferably from about 50 to about 180, more preferably from about 60 to about 130 g/mol.


The aminofunctional material may be substantially free of any hydrophilic moieties other than primary and/or secondary amines, as such hydrophilic moieties tend to increase the water-solubility of the material. Such hydrophilic moieties may include tertiary amine groups, hydroxyl groups (preferably hydroxyl groups that are not separated by two carbon atoms from a primary or secondary amine group), polyether groups, and carboxyl groups or salts thereof. Preferably, the material comprises no (zero) hydrophilic moieties, other than primary or secondary amines. If the material does contain hydrophilic moieties other than primary or second amines, then it is preferred that the Hydrophilic Group Equivalent Weight of the aminofunctional material is greater than 100. As used in the present disclosure, the Hydrophilic Group Equivalent Weight is defined as molecular weight of the aminofunctional material divided by the number of hydrophilic groups in a molecule of the aminofunctional material, not including primary and secondary amines. This is represented below as an equation:

It is believed that certain aminofunctional materials are likely to work better than others in the compositions of the present disclosure due to their amine moiety type and/or structure. For example, the aminofunctional material may be characterized by one of the following: (a) comprising a total of one primary amine moiety and no secondary amine moieties; or (b) comprising a total of two primary amine moieties and no secondary amine moieties; or (c) one primary amine moiety and one secondary amine moiety, preferably where the primary amine moiety and the secondary amine moiety are separated by two carbon atoms; or (d) one primary amine moiety or secondary amine moiety that is separated by two carbon atoms from a hydroxyl group.


The aminofunctional material may be selected from the group consisting of: (a) an aliphatic aminofunctional material, which may be linear or branched, preferably branched; (b) a cycloaliphatic aminofunctional material; (c) an aminofunctional silane; (d) an aminoalcohol where one primary amine moiety or secondary amine moiety is separated by two carbon atoms from a hydroxyl group; or (e) mixtures thereof. The aminofunctional material may be substantially free of aromatic amines (e.g., where an aminofunctional moiety is directly attached to an aromatic ring), or even substantially free of aromatic moieties altogether, as such moieties tend to increase the solubility of the aminofunctional material and therefore may make it less likely to associate with the hydrophobic silicone.


The aminofunctional material may comprise aliphatic aminofunctional material that is linear. Suitable linear aliphatic aminofunctional materials may include octylamine, nonylamine, decylamine, or mixtures thereof. For such materials, it is believed that monoamines are preferred, as diamines tend to be solid at room temperature and more difficult to process.


Suitable aliphatic aminofunctional materials may preferably be branched. Such materials may include: 2-ethylhexylamine; tridecylamine, branched; t-butylamine; neopentanediamine (2,2-dimethyl propane-1,3-diamine); trimethyl-1,6-hexanediamine; 2-aminoheptane; 2-butyloctylamine; or mixtures thereof.


Suitable cycloaliphatic amines preferably have a structure according to Formula (III):

where the substituents R1, R2, R3, R4, R5 and R6 are independently selected from —NH2, —H, hydrophilic groups, alkyl groups, alkenyl groups, substituted alkyl groups, cycloaliphatic groups having from 1 to 10 carbon atoms, or substituted cycloaliphatic groups having from 1 to 10 carbon atoms; n is from 0 to 3, preferably n is 1; with the proviso that the compound according to Formula (III) has from 1 to 3 primary and/or secondary amine groups, preferably from 1 to 3 primary amine groups, more preferably 2 primary amine groups. It may be preferred that the cycloaliphatic aminofunctional material also meets the criteria set forth above with regard to the Amine Equivalent Weight and/or the Hydrophilic Group Equivalent Weight, preferably both.


The alkyl, alkenyl, and/or substituted alkyl groups of Formula (III), if any, may independently be linear or branched. Substituted alkyl and substituted cycloaliphatic groups of Formula (III), if any, can be substituted with primary and/or secondary amine groups.


Suitable cycloaliphatic amines may include the following materials, or mixtures thereof:

Particularly preferred cycloaliphatic amines may include methylcyclohexane diamines, preferably: 2-methylcyclohexane-1,3-diamine; 4-methylcyclohexane-1,3-diamine; or mixtures thereof.


The aminofunctional material may comprise an aminofunctional silane. Suitable aminofunctional silanes may include trialkoxy(aminoethylaminopropyl)silane, alkyl dialkoxy(aminoethylaminopropyl)silane, dialkyl alkoxy(aminoethylaminopropyl)silane, trialkoxy(aminopropyl)silane, alkyl dialkoxy(aminopropyl)silane, dialkyl alkoxy(aminopropyl)silane, or mixtures thereof. Preferred aminofunctional silanes may include trimethoxy(aminoethylaminopropyl)silane, triethoxy(aminoethylaminopropyl)silane, methyl dimethoxy(aminoethylaminopropyl)silane, ethyl dimethoxy(aminoethylaminopropyl)silane, dimethyl methoxy(aminoethylaminopropyl)silane, dimethyl ethoxy(aminoethylaminopropyl)silane, trimethoxy(aminopropyl)silane, triethoxy(aminopropyl)silane, methyl dimethoxy(aminopropyl)silane, ethyl dimethoxy(aminopropyl)silane, dimethyl methoxy(aminopropyl)silane, dimethyl ethoxy(aminopropyl)silane, or mixtures thereof.


The aminofunctional material may comprise an aminoalcohol, preferably where one primary amine moiety or one secondary amine moiety is separated by two carbon atoms from a hydroxyl group. Although aminofunctional materials having hydrophilic groups such as hydroxyl groups are typically not preferred for use in the presently disclosed compositions, aminoalcohols having this particular configuration can be useful. Preferred aminoalcohols may include 2-(butylamino)ethanol, 1-(cyclohexylamino)2-propanol, 1-(dodecyloxy)-3-[(2-hydroxyethyl)amino]-2-propanol, 3-(dodecylamino)-1,2-propanediol, or mixtures thereof.


Another suitable aminofunctional material is 1,3-bis(3-aminopropyl) tetramethyldisiloxane.


Fragrance Material


The fragrance premix composition comprises fragrance material. Such materials are desirably formulated in final products to provide a pleasant aroma upon usage, and/or to cover up undesirable smells.


The fragrance material may comprise one or more perfume raw materials (“PRMs”). One or more of the perfume raw materials may comprise an aldehyde moiety, a ketone moiety, or combinations thereof. Without wishing to be bound by theory, it is believed that PRMs with aldehyde or ketone moieties can interact with the amine moieties of the aminofunctional material (and the aminosilicone polymer, if present) described herein in a way that results in improved perfume deposition and/or performance in a consumer product. Furthermore, it is believed that PRMs having certain structures are more likely to perform better than others.


In general, the term “perfume raw material” (or “PRM”) as used herein refers to compounds having a molecular weight of at least about 100 g/mol and which are useful in imparting an odor, fragrance, essence, or scent, either alone or with other perfume raw materials. Typical PRMs comprise inter alia alcohols, ketones, aldehydes, esters, ethers, nitrites, and alkenes, such as terpene. A listing of common PRMs can be found in various reference sources, for example, “Perfume and Flavor Chemicals”, Vols. I and II; Steffen Arctander Allured Pub. Co. (1994) and “Perfumes: Art, Science and Technology”, Miller, P. M. and Lamparsky, D., Blackie Academic and Professional (1994).


The PRMs may be characterized by their boiling points (B.P.) measured at the normal pressure (760 mm Hg), and their octanol/water partitioning coefficient (P), which may be described in terms of log P, determined according to the test method below. A perfume having a variety of PRMs characterized by different boiling points and/or log Ps may be desirable, for example, to provide fragrance benefits at different touchpoints during normal usage.


As mentioned above, one or more of the perfume raw materials may comprise an aldehyde moiety, a ketone moiety, or combinations thereof. The one or more perfume raw materials may comprise an aldehyde moiety. The one or more perfume raw materials may comprise a ketone moiety.

or

    • e. mixtures thereof,


      where each R and/or R1 is independently a suitable substituent moiety of the PRM, for example selected from the group C3-C18 alkyl, C3-C18 alkenyl, and C3-C18 substituted alkyl; or selected from the group H, C1-C3 alkyl, and C1-C2 alkoxy. To note, the structures of a.-d. are selections of the PRMs described in groups a.-d. above.

To note, the specifically named perfume raw materials of groups a.-d. are selections of the structures provided in groups a.-d. in each of the previous sections above.


Perfume raw materials having these identities and/or structures (e.g., those described in groups a.-d.) have been found to perform surprisingly well in compositions according to present disclosure, as evidenced by relatively high headspace measurements on treated fabric, compared to other PRM structures. Furthermore, it is believed that vanillin and/or ethyl vanillin (described in group e. of the last list above) also perform substantially well in the methods and compositions of the present disclosure, even though such performance may not be substantially indicated by the present headspace analysis method.


The fragrance premix composition may comprise from about 1% to about 50%, or from about 5% to about 50%, or from about 10% to about 40%, or from about 15% to about 30%, or from about 15% to about 25%, by weight of the fragrance premix composition, of the one or more perfume raw materials.


As describe above, it is believed that the aldehyde and/or ketone moieties of the one or more perfume raw materials associates with the amine moieties of the aminofunctional material, and potentially with the amine moieties of the aminosilicone polymer, if present. Therefore, it may be desirable to provide the components at levels where the ketone/aldehyde moieties and the amine moieties are in molar amounts that are reasonably close to each other. For example, if the total moles of primary and secondary amine moieties present in the composition as provided by an aminosilicone polymer (if any) and the aminofunctional material is “X”, and if the total moles of aldehyde moieties and/or ketone moieties (preferably aldehyde moieties) present in the composition as provided by the one or more perfume raw materials is “Y”, then the ratio of X:Y may be from about 2:1 to about 1:10, preferably from about 2:1 to about 1:5, more preferably from about 2:1 to about 1:2, more preferably from about 1.5:1 to about 1:1.5, more preferably from about 1:1 to about 1:1.5. In general, it may preferred to have an excess of the perfume raw materials in question (e.g., X:Y is 1:1 or greater), to ensure that the amine moieties are loaded or quenched as much as possible, thereby facilitating improved perfume delivery and/or performance.

Depending on the formulation and/or the intended end-use, the composition may be substantially free of certain surfactants. For example, liquid fabric enhancer compositions, such as fabric softeners, may be substantially free of anionic surfactant, as such surfactants may negatively interact with cationic ingredients.


The consumer product compositions may include conditioning actives. Compositions that contain conditioning actives may provide softness, anti-wrinkle, anti-static, conditioning, anti-stretch, color, and/or appearance benefits.


Conditioning actives may be present at a level of from about 1% to about 99%, or from about 1% to about 35%, or from about 1% to about 20%, or from about 1% to about 15%, or from about 1% to about 10%, or from about 1% to about 6%, by weight of the composition.

Suitable rheology modifiers and/or structurants may include non-polymeric crystalline hydroxyl functional structurants (including those based on hydrogenated castor oil), polymeric structuring agents, cellulosic fibers (for example, microfibrillated cellulose, which may be derived from a bacterial, fungal, or plant origin, including from wood), di-amido gellants, or combinations thereof.


The consumer product compositions made from the presently described methods may include free perfume. To provide a broader and more diverse scent profile, it may be desirable to include perfume raw materials in the free perfume of the consumer product composition that are not present in the silicone emulsion, and/or vice versa. For example, when the silicone emulsion comprises one or more perfume raw materials that comprise an aldehyde moiety, the free perfume of the consumer product composition may comprise one or more perfume raw materials that do not comprise an aldehyde moiety. Similarly, when the silicone emulsion comprises one or more perfume raw materials that comprise a ketone moiety, the free perfume of the consumer product composition may comprise one or more perfume raw materials that do not comprise a ketone moiety. The free perfume may include perfume raw materials that include aldehyde moieties, perfume raw materials that do not include aldehyde moieties, perfume raw materials that include ketone moieties, perfume raw materials that do not include ketone moieties, or mixtures thereof.

The consumer product composition may comprise from about 1% to about 99%, preferably from about 5% to about 98%, or from about 10% to about 95%, or from about 50% to about 95%, or from about 60% to about 95%, or from about 75% to about 95%, by weight of the consumer product composition, of water. Certain unit dose formulations may have relatively low amounts of water so as to not dissolve the water-soluble film; for example, the composition may comprise no more than about 20%, or no more than about 15%, or no more than about 12%, or no more than about 10%, by weight of the composition, of water. The fragrance premixes of the present disclosure may be particularly useful in liquid compositions that include a relatively high amount of water, as it is believed the hydrophobicity of the silicone enables the silicone, aminofunctional material, and fragrance material to partition from the water and to associate in the high-water matrix.

Test Methods

Miscibility Test—Measuring the Miscibility in Silicones Via UV-Vis % Transmittance


The relative miscibility of the components described herein is determined by measuring the percentage of light transmittance through samples using a UV-Vis Spectrophotometer operated in transmission mode, at 480 nm, using 1 cm path length cuvettes (VWR 97000-588), in accordance with the following procedure. Suitable instruments include the Beckman Coulter DU800, ID #1159577, MV31994, SN #8003432.


All sample preparations and analyses are conducted in a laboratory with air temperature of 22° C.+/−2° C. In a glass scintillation vial combine the predominant silicone present in the composition, along with the aminofunctional amine to be tested (for example, ethyl hexyl amine), at the ratio of 9.9:0.1 wt/wt. Cap the vial and mix the materials thoroughly for 5 minutes using a benchtop vortex mixer set to its highest speed. If two or more distinct layers of materials are clearly visible by eye in the vial after mixing, then the miscibility of the test material is considered to be indeterminate via this method. If distinct layers are not clearly visible by eye, then continue with the analysis.


Turn on the spectrophotometer lamps and allow them to warm up for 30 minutes prior to commencing measurements. Set the instrument to collect the measurement in Percentage Transmission (% T) mode, at a wavelength of 200-800 nm. Load all samples into 1 cm path length plastic cuvettes. If air bubbles are visible in the cuvettes, use a pipette to remove the bubbles, or let the bubbles settle out of the cuvette prior to measurement. Water, if present, should be removed (e.g., with a rotary evaporator) from the mixtures prior to taking the % T measurement.


Zero the baseline (run as the blank) with the respective neat silicone sample (see Table). Measure the % T of the mixture (for example, of the silicone & aminofunctional material, or of silicone+aminofunctional material+perfume raw material), as prepared under the previous instructions.


Report % T at 480 nm. Mixtures showing a relatively high % T indicate relatively good miscibility.


Extraction Percentage (Extr. %) of Silicone


To determine the Extraction Percentage (Extr. %) of a silicone polymer, a sample at 1:100 polymer-to-DI-water weight ratio is prepared generally following OECD 120 guidelines. (This method is substantially based on the OECD 120 guidelines as of the first filing date of this disclosure; the OECD 120 guidelines should be used to fill in any gaps in this method, should any exist.) Approximately 0.2 g of silicone polymer is spread evenly onto the bottom of a 250 mL polypropylene tri-pour cup, spreading across total surface area of bottom of beaker. 20 mL of DI water is pipetted to the polymer-containing cup, taking care not to disturb the polymer layer at the bottom. Beakers are covered with parafilm and placed on an orbital shaker at very low speed (mimicking the gentle motion of environmental water) for 24 hours and 6 days, at room temperature (approx. 21° C.). Each polymer is prepared in duplicate for each time point.


After the designated time, a 10 mL aliquot of water from each beaker is pipetted into a 15 mL centrifuge tube containing 300 uL of tetrahydrofuran (THF) and 50 μL of 100 ppm yittrium (aq). (In some cases, dilution with DI water may be necessary to stay within calibration range).


Samples are analyzed by inductively coupled plasma optimal emissions spectroscopy (ICP-OES) against an external calibration curve of either inorganic silicon or against a calibration curve of the silicone polymer being tested. Data is reported in polymer equivalents either by converting inorganic silicon to polymer equivalents using the silicon content of each polymer or reported straight from the polymer calibration curve.


The Extraction Percentage (Extr. %) of each polymer after a given time period (e.g., 24 hours and/or 6 days) is calculated from the mass of polymer equivalents measured in the aqueous phase versus the mass of the original polymer weighed into the tri-pour cup. Results are reported as Extr. %.


Determination of Amine Content and % Nitrogen


Total amine content, primary amine content, and/or % nitrogen of an aminofunctional silicone is determined according to the following method. More specifically, this method is used to determine the primary, secondary and tertiary amine values (meq/g) which are defined as the milliequivalents of amine functionality (primary, secondary and tertiary) present in one gram of a sample.


The method is based on compendial method ASTM D2074-07, which should be used to supplement this method if necessary. In broad stokes, a sample is dissolved in isopropyl alcohol and is titrated to a bromophenol blue end point using a standardized HCl solution.


The following materials are used: 0.1N Hydrochloric Acid in isopropyl alcohol (CAS 7647-01-1, 67-63-0; 99.5%; ex Fisher Scientific); Isopropyl Alcohol (CAS #67-63-0; 99%; ex EMD); Phenyl Isothiocyanate (CAS #103-72-0; 98%; ex Sigma Aldrich); Salicylaldehyde (CAS #90-02-8; 98%; ex Sigma Aldrich); Bromophenol Blue Indicator (0.1 wt % solution in ethanol or isopropyl alcohol; ex. Fisher Scientific).


Each of the following titrations should be repeated a total of three times. Furthermore, titrant volumes must be determined empirically. Titrant volumes should be between 1 and 20 mL. If titrant volumes are less than 1 mL, weigh more sample. If samples are more than 20 mL, weigh less sample. A buret such as Metrohm Dosimat 775 or equivalent may be used in the titrations. Regarding the yellow end point of the titrations—the yellow may fade back to green, but if it is a bright clear yellow, this is to be disregarded if additional 0.1N HCl does not change the original color.


A. Titration for Total Amine Content


Melt the sample (typically 100% active) in a water bath if it is not already a liquid. Mix thoroughly and accurately weigh out between 0.5 grams and 1.0 grams into a 250 mL Erlenmeyer flask (wide mouth; alkali resistant). Record the weight to four decimal places.


To the flask, add 50 mL of isopropyl alcohol. Add 0.5 mL of bromophenol blue indicator. Titrate with 0.1N HCl solution while swirling until it reaches the yellow end point. Record the volume of HCl used as V1,2,3.


B. Titration for Secondary and Tertiary Amine Content


Melt the sample (typically 100% active) in a water bath if it is not already a liquid. Mix thoroughly and accurately weigh out 1.0 grams into two 250 Erlenmeyer flasks. Record the weight to four decimal places. Mark the flasks S and T, respectively. To each flask, add 50 mL of isopropyl alcohol.


To flask S, add 1 mL of salicylaldehyde. Stir the solution (with a magnetic stir bar) for 30 minutes. Add 0.5 mL of bromophenol blue indicator solution and titrate while stirring with 0.1N HCl to a yellow end point. Record volume of HCl used as V2&3.


To flask T, add 1 mL of phenyl isothiocyanate. Stir the solution (with a magnetic stir bar) for 30 minutes. Add 0.5 mL of bromophenol blue indicator solution and titrate while stirring with 0.1N HCl to a yellow end point. Record volume of HCl used as V3.


C. Calculations for Amine Content


The variables in the calculations described below correspond to the following:

    • V: HCl required for titration of specimen in mL
    • N: normality of the HCl solution
    • S: specimen weight in grams (g)
    • meq/g: milliequivalents/gram
    • Total: Total Amine Value
    • AS: Amine value of the secondary and tertiary amine groups
    • TA: Tertiary Amine Value


Based on the measurements obtained related to the above titrations, the following calculations are used to determine the various amine contents.

D. Calculation of Nitrogen wt %


To determine the wt % of nitrogen in an aminofunctional silicone based on the amine content, use the following calculation.


The weight percentage of nitrogen in a compound can be calculated from the amine value (in meq/g) as follows:

(Amine Value/1000)×(MW of Nitrogen)×100=wt % Nitrogen

As an example, dimethylethanolamine has an amine value of 11.2 (in meq/g). Its weight percent of nitrogen (15.7 wt %) is as follows:

(11.2/1000)×(14.01)×100=15.7 wt % nitrogen


The following table shows wt % of nitrogen and equivalent amine values.

If the aminofunctional material contains nitrogen atoms that are not in the form of primary, secondary, and/or tertiary amines, the nitrogen content as a weight percent may be determined according to methods known to those having ordinary skill in the art.


E. Standard


To confirm quality control of the method, a suitable standard may be run—for example, dimethylethanol amine (a tertiary amine; 99.5%; available from Sigma Aldrich). For this particular amine, total amine and tertiary amine content should be 11.2±0.2 meq/g. Primary and Secondary amine content should be <0.1 meq/g.


Viscosity Test Method


The following test method is used to determine the viscosity of an aminofunctional silicone and/or an emulsion containing such a silicone.


A preliminary estimate of the sample viscosity at 25° C. is used to select the appropriate instrument geometry to be used during the final viscosity measurement analyses, which are conducted on a model AR-G2 Rheometer (manufactured by TA Instruments Corp., New Castle, Del., USA). A preliminary estimate of the sample viscosity may be obtained by using a Brookfield Viscometer (Brookfield Engineering Laboratories Inc., Middleboro, Mass., USA). The selection of geometry for use on the AR-G2 Rheometer is determined in accordance with the following table:

Couette/Cup and Bob










The geometry attached to the instrument, the instrument is mapped, the gap distance is zeroed, and the instrument temperature is set to 25° C. The measurement mode is selected as Stiff Mode when using parallel plates, or to Soft mode when using the couett cup and bob geometry. Sample material is mounted into the sample holding geometry e.g., the base plate. The minimum gap distance allowable between the base plate and the selected geometry is 10× the diameter of the largest common particle present in sample. If there are common particles in the sample which have a diameter greater than 100 μm (as determined microscopically), then the gap value is set to 10× the diameter of the largest common particle, otherwise the gap distance is set to the default value of 1000 μm (ie 1 mm). The selected geometry is lowered to the appropriate gap and a plastic tool is used to trim off any excess sample material. The sample material is allowed to equilibrate to the temperature of the instrument. Three rheological measurement analyses are conducted, namely: Flow Curve, Stress Sweep, and Frequency Sweep, using the following selections and settings:

    • Flow Curve: select Stepped Flow 0.01 to 100; 10 pts/decade; shear stress; constant time 20; average last 10.
    • Stress Sweep: set the Stress Range as 0.01 to 100 Pa; set the Frequency at 1 rad/s.
    • Frequency Sweep: Set the Angular Frequency Range as 0.1 to 100.


To ensure that the analysis is conducted within the Linear Viscoelastic Region set the Stress value at a third of the stress value that was present when G′ started to degrade during the prior Stress Sweep analysis.


The viscosity value for the test material obtained at 25° C. is reported, for example at 0.1 rad/s.


Particle/Droplet Size


The droplet size for the siloxane compounds are analyzed as the emulsion and in the fabric softener utilizing a Horiba, Partica, Laser Scattering, Particle Size Distribution Analyzer LA-950V2 with a static quartz cell and operated in accordance with the manufacturer's instructions.


HLB Value of Nonionic Surfactants


Nonionic surfactants can be classified by the balance between the hydrophilic and lipophilic moieties in the surfactant molecule. The hydrophile-lipophile balance (HLB) scale devised by Griffin in 1949 is a scale from 0-20 (20 being Hydrophilic) used to characterize the nature of surfactants. The HLB of a surfactant may be calculated as follows:

HLB=20*Mh/M

where Mh is the molecular of the hydrophilic portion of the molecule, and M is the molecular mass of the whole molecule, giving a result on a scale of 0 to 20. An HLB value of 0 corresponds to a completely lipophilic/hydrophobic molecule, and a value of 20 corresponds to a completely hydrophilic/lipophobic molecule. See Griffin, W. C. Calculation of HLB values of Nonionic Surfactants, J. Soc. Cosmet. Chem. 1954, 5, 249-256. The HLB values for commonly-used surfactants are readily available in the literature (e.g., HLB Index in McCutcheon's Emulsifiers and Detergents, MC Publishing Co., 2004). The HLB value for a mixture of surfactants can be calculated as a weighted average of the HLB values of the surfactants.


Fabric Treatment Method


Test fabrics are treated with fabric conditioning compositions in a miniwasher according to the following procedure.


Five full-sized cotton terry cloths (30 cm×30 cm) (or their equivalent: e.g., ten half-sized terries, or twenty quarter-sized terries) are used for each test leg. The terries are pre-conditioned with three cycles of liquid detergent and fabric softener, both of which are free of perfumes.


Weigh out desired number of detergent doses into plastic cups and secure with lids such that each dose of detergent is 9.98 g (+/−0.02 g) for each treatment for each cycle. For example, if five treatments of one wash cycle is being run, five doses of detergent would be needed, one dose for each treatment. Repeat the same process with the liquid fabric softener samples such that each dose is 5.68 g (+/−0.02 g) for each treatment.


For the test, the following treatment conditions are used:

    • Machine Type: Miniwasher (designed to mimic top-loader conditions)
    • Machine Cycle: 80 spm (normal)
    • Wash Temp: approx. 30.6° C. (87° F.)
    • Rinse Temp: approx. 15.6° C. (60° F.)
    • Water Hardness: about 100 ppm (6 gpg)
    • Wash Time: 12 mins
    • Rinse Time: 2 mins
    • Water Volume: 2 gal fill (˜8 L)
    • Dry Type: Electric


Turn on the mini-washer and water mixing station. Set the water mixing station using the water specifications mentioned above. Fill each drum of the mini-washer to the 2 gal line, adding the detergent to each drum respectively while the drum is filling. Rinse the cup with the water coming into the drum such that all of the detergent is added to and well dispersed throughout the drum. Once the drums are filled with water and the dispersed detergent, add the fabrics and set the agitation time to 12 mins. At the end of the agitation time, set the spin timer to 2 mins to allow the water to spin out of the drum. Once the spin cycle is complete, remove the fabrics from each drum ensuring each fabric bundle remains separate from the others. Start the fill cycle again using the water specifications for the rinse cycle to the 2 gal line (the water mixing station should automatically switch to the rinse water specifications). During the fill cycle, add the liquid fabric softener dose to each drum respectively. Ensure complete addition and dispersion of the liquid fabric softener composition by rinsing the dosing cup with the incoming water. Once the drum is filled with water and the dispersed fabric softener, the fabrics can be added back to each respective drum. Set the agitation cycle to 2 mins and allow to run. After the agitation is complete, set the spin cycle to 2 mins to allow all of the water to spin out. After completing the spin cycle, each fabric bundle is placed into a separate electric dryer and dried on a high/cotton setting. Once the fabrics are dry, they are placed in a constant temperature/constant relative humidity room set at 75 F and 50% relative humidity for at least 4 hrs (preferably overnight) to equilibrate.


Headspace Analysis on Fabric


To prepare the treated fabric for analysis, cut one 2.54 cm×5.08 cm (1 inch×2 inch) cotton swatch from the cotton terry that is prepared and treated according to the above methods. Place each piece in a 20 mL headspace vial. Re-equilibrate for four hours in a Controlled Humidity and Temperature room (21 C/50% humidity). After the four hours the vials are capped and analyzed via Headspace solid phase micro-extraction/Gas Chromatography/Mass Spectrometry.


The equipment used for analysis is as follows: Gas Chromatograph 7890B equipped with a Mass Selective Detector (5977B) (MSD) and Chemstation quantitation package; Gerstel Multi-Purpose sampler equipped with a solid phase micro-extraction (SPME) probe or similar system; Divinylbenzene/Carboxen/Polydimethylsiloxane SPME fiber from Supleco part #57298-U (or similar fiber); column with 30 m×0.25 mm nominal diameter, 0.25 μm film thickness, J&W 122-5532UI DB-5; 20 mL headspace vials.


The Gerstel auto sampler parameters are as follows: SPME—from Incubator; Incubation Temperature—65° C.; Incubation Time—10.00 min SAMPLE PARAMETERS; Vial Penetration—22.00 mm; Extraction Time—5.00 min; Inj. Penetration—54.00 mm; Desorption Time—300 s.


The GC oven parameters are as follows for the Front SS Inlet He: Mode—Splitless; Heater—270° C.; GC Run Time—14.28 min. For the Oven: Initial temp.—40° C.; Hold Time—0.5 min; Heating Program—Rate of 17° C./min, Temp of 270° C., Hold Time of 0.25.


The MSD parameters are as follows: Run in scan mode with a minimum range of 35 to 350 m/z; calibration curves are generated from the standards perfume material; Chemstation software (or similar quantitation software) calculates this amount using the quantitation software for each perfume component.

Example 1. Characteristics of Certain Silicone Polymers

The following tables provide characteristics of certain silicone polymers. The silicones of the same numbers (“Silicone No.”) in Tables 1A, 1B, and 1C correspond to each other. Some of the silicones (e.g., Silicone Nos. 7-10) may be outside the scope of the silicones useful in the present premixes and/or consumer product compositions. For example, the amine content and/or Extr. % may be relatively too high, or the molecular weight too low, which may be associated with relatively greater solubility in water.

Example 2. Miscibility of Certain Silicone Polymers and Aminofunctional Materials

In this experiment, different combinations of silicone polymers and aminofunctional materials are tested (at a 99:1 weight ratio) according to the Miscibility Test provided in the Test Methods section above. Descriptions for the silicone polymers are provided above in Example 1.


Table 2 shows the results of the Miscibility Test for each of the following combinations. Generally, relatively higher % T values show better miscibility and are preferred. More specifically, % T values equal to or greater than 90 is most preferred, followed by a preference for a % T of from 60 to less than 90, followed by a preference for a % T of from about 40 to less than 60.

As shown in Table 2, different aminofunctional materials may have different miscibility with different silicones, as evidenced by different % T values; see, for example, methyl cyclohexyl diamine (aminofunctional material #2). Furthermore certain aminofunctional materials have low miscibility with the tested silicones, as evidenced by low % T values; see, for example, PEI-800 Mw (a polyethyleneimine polymer having a molecular weight of approximately 800), which is likely not suitable for fragrance premix compositions according to the present disclosure (at least not in combination with the tested silicones).


Example 3. Miscibility of Certain Silicone Polymers, Aminofunctional Materials, and PRMs

In this experiment, different combinations of silicone polymers, aminofunctional materials, and a perfume raw material comprising an aldehyde moiety (at a 99:1:1 weight ratio; a ternary system) are tested according to the Miscibility Test provided in the Test Methods section above. Descriptions for the silicone polymers are provided above in Example 1.


Table 3 shows the results of the Miscibility Test for each of the following combinations. Generally, relatively higher % T value show better miscibility and are preferred, as described in Example 2.

*It has been found that DMS-T31 + cyclamal is relatively cloudy, leading to misleading results when used as the Blank. (Cyclamal includes an aromatic ring and has reduced miscibility with PDMS.)






As shown in Table 3, different ternary systems may have different miscibilities, as evidenced by % T values. Furthermore, even when the silicone and the aminofunctional material are reasonably miscible, the addition of a PRM can have a detrimental effect; see, for example, methyl cyclohexyl diamine (aminofunctional material #2) in Table 2, Leg A vs. Table 3, Leg A.


Also note, for example, the PEI-800 Mw has relatively low miscibility in Legs A and B, as evidenced by low % T values. The % T is relatively higher in Leg C, but the silicone (DMS-A11) has a solubility (as evidenced by amine value and/or Extr. %) that may be undesirably high.


Example 4. Effect of PRM Selection on Miscibility

This experiment shows the relative effects that the selection of certain perfume raw materials may have on the overall miscibility of the ternary system (silicone, aminofunctional material, and perfume raw material). Each leg uses the same silicone polymer (DMS-T31) and a different perfume selection (none, cyclamal, or ligustral); each leg tests the mixture with four aminofunctional materials according to the Miscibility Test provided above (e.g., % T at 480 nm compared to a blank). Structures of cyclamal (i.e., 3-(4-Isopropylphenyl)-2-methylpropanal) and ligustral (i.e., 2,4-Dimethylcyclohex-3-ene-1-carbaldehyde) are provided below.

The results are provided in Table 4. Generally, relatively higher % T value show better miscibility and are preferred, as described in Example 2.

*Ligustral is non-aromatic and is relatively soluble in PDMS, so the binary system can be used as the Blank; compare to Cyclamal, discussed in the previous example.






As shown in Table 4, the selection of one PRM vs. another can have an effect on the miscibility of the ternary system. Compare, for example, Legs A, B, and C for methyl cyclohexyl diamine (aminofunctional material #2) in Table 4.


Again, the % T values for the tests that included PEI-800 Mw are relatively low, indicating low suitability for fragrance premix compositions according to the present disclosure.

13.2 g of the Lilial Accord mixture is added to the aminofunctional silicone/Baxxodur EC 210 mixture thoroughly mixed with overhead mixing with a four-blade impeller for 15 minutes.


B. Consumer Product


The Fragrance Premix Composition (73.3 grams) is combined with 1806.7 grams of molten polyethylene glycol (Pluriol E 8000 Prill supplied by BASF Corporation) and 120.0 grams of fragrance. The blend is mixed and solidified into consumer product particles having an average diameter of about 0.3 cm to about 1.5 cm, and/or an average mass of from about 1 mg to about 1 g.


The resulting consumer product is a plurality of particles that are suitable for addition to the wash cycle of an automatic fabric washing machine, optionally in combination with a laundry detergent. When the consumer product is diluted with water, a plurality of droplets (believed to contain the silicone polymer, the aminofunctional material, and the PRMs of the premix) having a mean diameter of from about 1 micron to about 10 microns is achieved.


Example 7. Exemplary Method of Making a Fragrance Premix Composition in the Form of an Emulsion and Subsequent Formulation into a Consumer Product

A. Fragrance Premix Composition (emulsion)


56.7 grams of an aminofunctional silicone is provided. The aminofunctional silicone is KF-861, supplied by Shin-Etsu Chemical Co., Ltd.; the structure is shown in Example 6, above.


The 56.7 grams of aminofunctional silicone is mixed with 3.4 grams of Baxxodur EC 210, supplied by BASF Corporation, 1.0 gram of a nonionic emulsifier (Tergitol 15-S-9 supplied by Dow Chemical Company, Midland, Mich.) and 3.0 grams of a second emulsifier (Surfonic L24-9 supplied by Sasol Chemicals, West Lake, La.), using an IKA overhead mixer set to 250 rpm.


10 grams of water is slowly added and mixed for 15 minutes. Mixing speed is increased slowly as viscosity of the mixture increases. 15 grams of additional water is added slowly while mixing for another 10 minutes at a speed between 300-400 rpm. Mixing speed is lowered if the viscosity of mixture decreases. 11 grams of additional water slowly added while continuing to mix for another 10 minutes. Mixing is continued for another 30 minutes at a speed of about 250 rpm.


The resulting aminofunctional silicone/Baxxodur EC 210 emulsion can be analyzed for droplet size via Horiba using the static cell. For droplet size measurement, the emulsion is diluted to 0.1 wt % emulsion in deionized water (e.g., 0.1 wt parts emulsion, 99.99 wt parts DI water).


13.2 g of the Lilial Accord mixture (see Example 6, above) is slowly added to the aminofunctional silicone emulsion with overhead mixing with a four-blade impeller and gently and thoroughly mixed for 15 minutes. The result is a Fragrance Premix Composition.


B. Consumer Product


The Fragrance Premix Composition Emulsion (113.3 grams) is combined with 1756.6 grams of molten polyethylene glycol (Pluriol E 8000 Prill supplied by BASF Corporation) and 119.8 grams of fragrance. The blend is mixed and solidified into consumer product particles having an average diameter of about 0.3 cm to about 1.5 cm, and/or an average mass of from about 1 mg to about 1 g.


The resulting consumer product is a plurality of particles that are suitable for addition to the wash cycle of an automatic fabric washing machine, optionally in combination with a laundry detergent. When the consumer product is diluted with water, a plurality of droplets (believed to contain the silicone polymer, the aminofunctional material, and the PRMs of the premix) having a mean diameter of from about 1 micron to about 10 microns is achieved.

A. Fragrance Premix Composition


56.65 grams of an aminofunctional silicone is provided. The aminofunctional silicone is KF-861, supplied by Shin-Etsu Chemical Co., Ltd.; the structure is shown in Example 6, above.


The 56.7 grams of the aminofunctional silicone is thoroughly mixed with 3.4 grams of Baxxodur EC 210, supplied by BASF Corporation, using an IKA overhead mixer set to 250 rpm.


13.2 g of the Lilial Accord mixture (see Example 6, above) is added to the aminofunctional silicone/Baxxodur EC 210 mixture thoroughly mixed with overhead mixing with a four-blade impeller for 15 minutes. The cloudy Fragrance Premix Composition is made substantially transparent under reduced pressure at 40° C. via rotary evaporation.


B. Consumer Product


The substantially transparent Fragrance Premix Composition is combined with 1806.7 grams of molten polyethylene glycol (Pluriol E 8000 Prill supplied by BASF Corporation) and 120.0 grams of fragrance.

The resulting consumer product is a plurality of particles that are suitable for addition to the wash cycle of an automatic fabric washing machine, optionally in combination with a laundry detergent. When the consumer product is diluted with water, a plurality of droplets (believed to contain the silicone polymer, the aminofunctional material, and the PRMs of the premix) having a mean diameter of from about 1 micron to about 10 microns is achieved.


Example 9. Performance/Headspace Analysis

The following experiment is performed to demonstrate performance benefits associated with the fragrance premix compositions according to the present disclosure. In sum, two consumer product compositions are made—specifically, liquid fabric conditioning compositions. To one, perfume is added as fragrance premix composition according to the present disclosure; to the other, perfume is added neat. Fabrics are treated with each consumer product composition, and the headspace above the treated fabrics is analyzed for the perfumes. In general, greater amounts of perfume found in the headspace indicate the more perfume was deposited onto, and/or released from, the fabric.


A test perfume accord is made by mixing together the following perfume raw materials in the provided weight ratio.

A fragrance premix composition is prepared by combining and mixing 78.91 wt % of aminofunctional silicone KF-867S, supplied by Shin-Etsu Chemical Co., Ltd., 4.27 wt % of aminofunctional material Baxxodur EC 210, supplied by BASF Corporation, and 16.82 wt % of the test perfume accord.


Fabric conditioning compositions are prepared according to the following procedure. A base fabric conditioning composition is provided, which contains a mixture of 9.5 wt % N,N di(tallowoyloxyethyl)-N,N dimethylammonium chloride in water. To one sample of the base fabric conditioning composition, the test perfume accord is added neat; to another sample, the fragrance premix composition is added. Both are added in amounts to provide about 0.3% of total perfume to the final fabric conditioning composition. The mixture is stirred for 15 min with an IKA RW 20 D S1 Mixer, Model RW20D-S1, and IKA R1342 impeller blade at 350 rpm. A structurant and a deposition aid is added, and the mixture is stirred for 10 min. Water is added if needed to standardize the concentration of N,N-di(tallowoyloxyethyl)-N,N dimethylammonium chloride amongst test legs to 8 wt %, and the mixture stirred for 5 min. The pH is adjusted to 2-3 with 1N HCl.


Test fabrics are treated according to the Fabric Treatment Method as provided in the Test Methods section. One fabric set is treated with the fabric conditioning composition made with the test perfume accord provided neat (Sample 1). Another fabric set is treated with the fabric conditioning composition made with the fragrance premix composition (Sample 2).


After treatment, the concentration of the perfume raw materials above each fabric is determined via the Headspace Analysis on Fabric Method. Results are provided in Table 7.

The results in Table 10 (specifically, Emulsion 4) show that emulsions according to the present disclosure can result in emulsions characterized by relatively small droplet sizes while still comprising a relatively high amount of perfume raw material. As mentioned above, it is believed that relatively small droplets (e.g., a mean diameter of about 1 micron to about 10 microns, preferably from about 1 micron to about 5 microns) are preferred for performance and/or stability reasons.


In particular, note that Comparative Emulsion 1 and Emulsion 4 carry the same amount of perfume, but that the droplet size of Emulsion 4 is much smaller. Additionally, the mean droplet diameters of Comparative Emulsion 3 and Emulsion 4 are somewhat similar, but the amount of perfume carried in Emulsion 4 is greater.


C. Performance and Stability in a Pastille


The emulsions of Table 9 are prepared and incorporated into various particulate laundry additives, specifically solid pastille products similar to those sold as DOWNY UNSTOPABLES™ (ex The Procter & Gamble Company). Additionally, one of the formulations includes the active materials of Emulsion 4 added separately (e.g., as individual components, rather than as a premix); see comparative Product 4 below. The emulsions (and separately added materials) are included in such amounts so as to deliver 0.55 wt % of perfume to the final product. The formulations of the different legs are provided below in Table 11.


The products are used to treat fabrics in a mini-washer, and headspace analysis above the treated fabrics is performed to test perfume delivery performance; greater headspace values (as nmol/L) indicate the presence of relatively more perfume. Additionally, color measurements are taken for each product (made fresh), and differences compared to Product 1 are reported as ΔE values; greater ΔE values indicate greater color differences from Product 1, which generally has a white-ish color. In contrast, greater ΔE values in Products 2-5 are associated with yellowing or even brownish coloration.

As shown by the results in Table 11, Product 5 shows the best/most desirable combination of headspace results and color change results. For example, Product 1 (the PRM-only control) shows a relatively desirable color, but also low headspace results. Product 2 shows desirable headspace results, but a relatively high degree of color change. Product 3 shows relatively low headspace results and a high degree of color change; furthermore, a relatively large amount of emulsion is required to deliver the desired amount of perfume. Product 4, in which the materials are added separately, shows relatively low color change, but also less perfume in the headspace compared to Product 5.


D. Performance and Stability in a Liquid Fabric Enhancer


The emulsions of Table 9 are prepared and incorporated into various liquid fabric enhancer products, similar to those sold as liquid DOWNY™ fabric softeners (ex The Procter & Gamble Company). Additionally, one of the formulations includes the active materials of Emulsion 4 added separately (e.g., as individual components, rather than as a premix); see comparative Product 9 below.


The Base Liquid Softener provided in Table 12 comprises about 7 wt % of a diester quat softening material and is free of perfume. The emulsions (and separately added materials) are included in such amounts so as to deliver 0.30 wt % of perfume to the final product. The formulations of the different legs are provided below in Table 12.


The products are used to treat fabrics in a mini-washer, and headspace analysis above the treated fabrics is performed to test perfume delivery performance; greater headspace values (as nmol/L) indicate the presence of relatively more perfume. Additionally, color measurements are taken for each product (made fresh), and differences compared to Product 6 are reported as ΔE values; greater ΔE values indicate greater color differences from Product 6, which generally has a white-ish color. In contrast, greater ΔE values in Products 7-10 are associated with yellowing coloration.

As shown in Table 12, Product 10 shows a desirable combination of headspace data, color data, and a relatively low amount of fragrance premix required to delivery the desired amount of perfume.


It is also worth recalling that Comparative Emulsion 2, which is used to make Comparative Product 7, is characterized by a relatively large (and less preferable) mean droplet size; see Table 10 above.
