Field of the Invention
This application relates to solid or liquid textile-treating compositions, as well as their use and manufacture. The application also relates to cleaning agent compositions employing solid or liquid textile-treating compositions, and their use and manufacture.
Description of the Related Art
Textiles can become hard due to repeated washings. Also, after washing, textiles can have an undesirable smell. To restore their softness, improve their scent, or impart other desirable properties, textiles are often treated by additional processes that are separate from their washing. The treatments are separate because the textile-treating compositions are often not compatible with the washing detergent. These additional processes can be done, for example, in the washer during an added rinse cycle, or in the dryer. However, separate treatments have drawbacks. For example, when a textile is treated with a liquid fabric softener, an additional rinse cycle may be needed, which uses extra water and electricity to power the washer. The use of extra water and electricity can be detrimental to the environment. Also, some separate treatments employ liquid compositions such as liquid fabric softeners. These liquid compositions contain excess weight and have excess volume imparted by an inert ingredient: water. The water in the liquid compositions makes liquid compositions expensive to transport and can generate excess container waste.
United States Patent Application Publication No. 2009/0082244 (“the '244 application”) relates to a solid, textile or skin care composition which comprises a water-soluble carrier, a textile-softening clay and a textile or skin care compound. The compositions of the '244 application can contain colorants. Preferred colorants are alleged to possess high storage stability, are not affected by other composition ingredients, and do not color treated textiles.
United States Patent Application Publication No. 2009/0042766 (“the '766 application”) relates to solid, textile care compositions having a water-soluble carrier, a textile care compound, and a perfume. The solid, textile care compositions can be present in particulate form, and can be included in washing or cleaning compositions. The compositions of the '766 application can contain pigments or dyes. Preferred dyes are alleged to possess high storage stability, are insensitive to other composition ingredients and light, and do not color treated textiles.
United States Patent Application Publication No. 2011/0082066 (“the '066 application”) is drawn to solid fabric care compositions comprising a water-soluble carrier, a water-soluble, polymer a fabric care compound, a polysaccharide and a fragrance. The water-soluble carrier is in particle form and is coated, with the polysaccharide being incorporated at least partly into the coating. The solid fabric care compositions can be included in washing or cleaning products. The solid fabric care compositions of the '066 application can be colored. The '066 application discloses that “ . . . cellulose or its derivatives increase the color stability of colored solid fabric care compositions.”
Thus, there remains a need for solid, textile-treating compositions that can be employed in the presence of a detergent while textiles are washed.
The compositions, containers containing the compositions, methods, and treated textiles provided are exemplary and are not intended to limit the scope of the claimed embodiments.
One aspect of the claimed embodiments is the use of colorant stabilizer(s) to stabilize colorant(s) in a solid or liquid composition. As described herein, it has been discovered that colorants widely thought to be stable were in fact unstable in solid, particulate compositions such as solid, textile-treating compositions (“STTCs”), and unstable in liquid compositions. The present inventors found that colorant stabilizers, that were not celluloses or cellulose derivatives, can be employed to stabilize colorants in solid, particulate compositions such as STTCs, and also in liquid compositions. It has also been discovered that in solid compositions, particulate compositions, and in liquid compositions, faded colorants could be “re-colorized” by the addition of colorant stabilizers that were not celluloses or cellulose derivatives.
In one embodiment is provided a solid, textile-treating composition (“STTC”). The STTC comprises a core, a coating that at least partially surrounds the core, and a flow aid physically associated with the coating such that the flow aid is partially or fully exposed on an outer surface of the coating. The core can comprise a carrier, which can be a water-soluble carrier. The core can be water-soluble. The coating can comprise a water-soluble polymer, a colorant, and a colorant stabilizer. The coating can also comprise a perfume (which may also be referred to herein, interchangeably and equivalently, as a fragrance). The flow aid can comprise a fabric softener.
Cores, water-soluble cores, carriers, water-soluble carriers, or STTCs can be particles. The particles can be free-flowing. The particles can be small. Thus, STTCs can be free-flowing small particles.
In a further embodiment is provided a cleaning agent composition comprising a detergent and an STTC. The detergent can comprise a surfactant.
Another provided embodiment is a container containing the cleaning agent composition or the STTC. Such containers can include, but are not limited to, pouches or other container forms comprising or made from thin films, such as polyvinylalcohol (PVOH) films. In certain such embodiments, the container containing the cleaning agent composition or the STTC can be in the form of a single-dose package suitable for addition to the washing machine at the beginning of the wash cycle.
A further embodiment is a method of perfuming a textile with an STTC.
Another embodiment is a method of softening a textile with an STTC.
Another embodiment is a method of perfuming a textile, e.g., delivering a fragrance to a textile, with an STTC.
Yet another embodiment is a method of perfuming and softening a textile with an STTC.
An additional embodiment is a method of cleaning a textile with a cleaning agent composition.
Another embodiment is a textile cleaned or perfumed or softened by an STTC.
An additional embodiment is a textile cleaned with a cleaning agent composition.
A further embodiment is a method of stabilizing a colorant in a granular composition, or in a solid composition, or in a liquid composition, where the colorant is stabilized by incorporating a colorant stabilizer in the composition.
Another embodiment is a method of visually designating when a granular composition, or a solid composition, or a liquid composition, has reached or passed its pull date by determining whether or when the composition becomes substantially colorless.
An additional embodiment includes a method of making a cleaning agent composition comprising blending a detergent with an STTC, a solid composition, a liquid composition, or a granular composition.
A further embodiment includes a method of making an STTC comprising at least partially coating a core to form a coated core and applying a flow aid to the at least partially coated core to form the STTC.
Another embodiment includes cleaning agent compositions or STTCs made by these methods.
A further embodiment is a solid textile-treating composition (“STTC”), comprising:
a water-soluble core comprising a water-soluble carrier;
a coating that at least partially covers the water-soluble core, the coating comprising
a water-soluble polymer;
a colorant selected from the group consisting of Acid Blue 80, Acid Red 52, Acid Violet 48, and combinations thereof; and
a flow aid physically associated with the coating such that the flow aid is partially or fully exposed on an outer surface of the coating; wherein the composition does not contain a colorant stabilizer. Surprisingly, it has been found that Acid Blue 80, Acid Red 52, and Acid Violet 48, do not display significant discoloration over time in STTCs and thereby do not require a colorant stabilizer.
A further embodiment includes a solid wash cycle conditioning agent (“SWCCA”) that includes: a) a non-ionic surfactant, which can be an EO/PO block copolymer, or a polysorbate, or a combination of these materials, wherein the non-ionic surfactant is a solid at about 25° C., wherein the non-ionic surfactant can have an HLB value of about 20 or more, and wherein the non-ionic surfactant can have a weight average molecular weight ranging from about 3,000 to about 12,000; and b) a fabric conditioning agent which can be, for example, a quaternary ammonium salt. The SWCCA can optionally include one or more plasticizers; one or more colorants; one or more colorant stabilizers; and/or one or more perfumes. It has been surprisingly found that solid wash cycle conditioning agents possess the ability to dissolve in cold water in a laundry wash cycle. Depending on the particle size of the SWCCA, the SWCCA may also optionally include a disintegrating agent, for example, as the particle size increases. The SWCCA can take a variety of shapes including pastilles, crystals, powders, pulverized powders, spray dried powders, agglomerated powders, checkers, round discs and tablets.

Discussion
Solid Textile-Treating Compositions
In one embodiment, provided is a solid textile-treating composition (“STTC”). The STTC can be used, for example to treat a textile.
In one embodiment, the STTC has a core that incorporates a carrier; a coating that at least partially covers the core; and a flow aid physically associated with the coating such that the flow aid is partially or fully exposed on an outer surface of the coating. The carrier or the core can be water-soluble. The coating includes a water-soluble polymer, a colorant, and a colorant stabilizer. The coating can further incorporate a perfume. The flow aid can include a fabric softener. And the STTC can further include additives.
The core or water-soluble core can contain ingredients or materials other than the carrier or water-soluble carrier. Alternatively, the core or water-soluble core can be the carrier or water-soluble carrier.
The STTC, in one embodiment, does not include a cellulose, a polysaccharide, alginic acid, algenic acid, or any combination thereof.
In one embodiment, the STTC does not comprise a fabric softener.
Cores, water-soluble cores, carriers, water-soluble carriers, or STTCs can be particles. The particles can be free-flowing. The particles can be small. Thus, an STTC can be a free-flowing small particle.
Cores and Carriers
A core may contain one or more carriers. The carrier can be, for example, an inorganic alkali metal salt, an inorganic alkaline earth metal salt, an organic alkali metal salt, an organic alkaline earth metal salt, a carbohydrate, a silicate, a urea, or any combination thereof.
Desirable carrier materials may be fully water-soluble.
Thus, in one embodiment, the core is a water-soluble core that comprises a water-soluble carrier. In other embodiments, the core is a water-soluble core that consists of a water-soluble carrier. In this case, the water-soluble core is the water-soluble carrier.
On the other hand, some desirable carriers may be water-insoluble or only partially water-soluble. Thus, in some embodiments, the core may comprise or consist of partially water-soluble carriers or water-insoluble carriers.
The water-soluble carrier can be, for example, a water-soluble inorganic alkali metal salt, a water-soluble alkaline earth metal salt, a water-soluble organic alkali metal salt, a water-soluble organic alkaline earth metal salt, a water-soluble carbohydrate, a water-soluble silicate, a water-soluble urea, or any combination thereof.
Alkali metal salts can be, for example, salts of lithium, sodium, potassium, rubidium, cesium, francium, or any combination thereof.

Inorganic salts, such as inorganic alkali metal salts and inorganic alkaline earth metal salts, do not contain carbon.
Organic salts, such as organic alkali metal salts and organic alkaline earth metal salts, contain carbon.
In one embodiment, the organic salt can be an alkali metal salt or an alkaline earth metal salt of sorbic acid (i.e., a sorbate). Sorbates can include, for example, sodium sorbate, potassium sorbate, magnesium sorbate, calcium sorbate, or any combination thereof.
The water-soluble carrier can be, for example, a water-soluble inorganic alkali metal salt, a water-soluble organic alkali metal salt, a water-soluble inorganic alkaline earth metal salt, a water-soluble organic alkaline earth metal salt, a water-soluble carbohydrate, a water-soluble silicate, a water-soluble urea, or any combination thereof.
The carrier or water soluble-soluble carrier can be, for example, sodium chloride, potassium chloride, calcium chloride, magnesium chloride, sodium sulfate, potassium sulfate, magnesium sulfate, sodium carbonate, potassium carbonate, sodium hydrogen carbonate, potassium hydrogen carbonate, sodium acetate, potassium acetate, sodium citrate, potassium citrate, sodium tartrate, potassium tartrate, potassium sodium tartrate, calcium lactate, water glass, sodium silicate, potassium silicate, dextrose, fructose, galactose, isoglucose, glucose, sucrose, raffinose, isomalt, xylitol, candy sugar, coarse sugar, or any combination thereof.

In one embodiment, the carrier or water-soluble carrier is a combination of sodium chloride and at least one of magnesium carbonate, potassium iodide, potassium iodidate, or any combination thereof.
In one embodiment, the core is a particle. The coating and the flow aid are then applied to the core to form an STTC that is also a particle. STTCs can thus be a collection of particles. STTCs can be made up of particles where each particle contains the same ingredients. Alternatively, an STTC can be a mixture of two or more distinct STTC particles where each distinct STTC particle has a different ingredient composition. When this is the case, the distinct STTC particles in the STTC composition can differ by one, or two, or three, or more ingredients.
Particle size can be measured across the longest distance (length) of a particle. The particle size can be an average particle size.
The particle size or average particle size can range, for example, from about 0.1 mm to about 50 mm. Particle size can be for example, individually, cores, water-soluble cores, carriers, water-soluble carriers, or STTCs.

Coatings
In one embodiment, the coating comprises a water-soluble polymer, a colorant, and a colorant stabilizer.
In a further embodiment, the coating further comprises a perfume (which is also referred to herein equivalently and interchangeably as, and will also be understood by those of ordinary skill in the art to be equivalent to and interchangeable with, the term “fragrance”).

United States Patent Application Publication No. 2011/0082066 (“the '066 application”) discloses that “ . . . cellulose or its derivatives increase the stability of colored solid fabric care compositions.” Applicants have found that colorant stabilizers, that are not celluloses or cellulose derivatives, can increase the stability of colored solid fabric care compositions (e.g., STTCs).
Thus, in one embodiment, at least some of the colorant in an STTC or solid composition is stabilized by a colorant stabilizer that is not a polysaccharide, a cellulose, an alginic acid, an algenic acid, or any combination of these. For example, in the coating of an STTC, at least some of the colorant is stabilized by a colorant stabilizer that is not a polysaccharide, a cellulose, an alginic acid, an algenic acid, or any combination of these.
In one embodiment, the coating has a thickness ranging from about 0.0001 mm to about 20 mm. The coating thickness can be an average of the thickest and thinnest portions of the coating added together and divided by two.

Water-Soluble Polymers
The water-soluble polymer can have, independently, a melting point temperature or a softening point temperature ranging, for example, from about 45° C. to about 300° C. Melting point temperature refers to the temperature at which the water-soluble polymer transitions from a solid state to liquid (free-flowing) state. Softening point temperature refers to the temperature at which the water-soluble polymer transitions from a solid state to a rubbery to viscous melt. Melting point temperature ranges and softening point temperature ranges of some water-soluble polymers can be found in U.S. Patent Application Publication Nos. 2009/0042766 and 2009/0082244.

Colorants
The coating can comprise a colorant and a colorant stabilizer. Applicants have unexpectedly found that the colorant can fade over time, changing hue or becoming essentially colorless or colorless. For example, Milliken Liquitint® colorants can fade when employed in a solid composition such as an STTC. Applicants have found that colorants, for example Milliken Liquitint® colorants, can be stabilized in a solid composition such as an STTC so that the colorants do not change hue or color or do not become substantially colorless or colorless. Stabilization is effected, in part or in whole, by a colorant stabilizer. Colorants, such as Milliken Liquitint® colorants, are thought to be stable over broad pH ranges and in diverse environments. Thus, it was surprising when test compositions such as STTCs containing colorants, for example Milliken Liquitint® colorants, became substantially colorless or colorless. It was equally surprising when adding an acid caused the color to return.
Without being bound by theory, it is possible that the colorant loses proton(s), which causes the colorant to change hue or become substantially colorless or colorless. The colorant stabilizer is believed to impart acidic proton(s) to the colorant, thereby stabilizing or restoring its color. Alternatively, the colorant stabilizer is believed to make the colorant more acidic, for example, by lowering the composition's pH.
The STTC or composition can have a pH ranging, for example, from about 2 to about 10. The pH of the STTC or composition can be, for example, about 2, about 3, about 4, about 5, about 6, about 7, about 8, about 9, or about 10.
The pH of the STTC or composition can range, for example, from about 2 to about 9, about 2 to about 8, about 2 to about 7, about 2 to about 6, about 2 to about 5, about 2 to about 4, or about 2 to about 3.
The pH of the STTC or composition can range, for example, from about 4 to about 8, about 4 to about 7, about 4 to about 6, or about 4 to about 5.
The pH of the STTC or composition can range, for example, from about 5 to about 8, about 6 to about 8, or about 7 to about 8.
The pH of the STTC or composition can range, for example, from about 2 to about 10, about 3 to about 10, about 4 to about 10, about 5 to about 10, about 6 to about 10, about 7 to about 10, about 8 to about 10, or about 9 to about 10.
The pH of the STTC or composition can be measured, for example, at room temperature by taking the pH of a 1% weight:volume solution of STTC or composition:water.
A solid composition such as an STTC, for example, in the absence of the colorant stabilizer, can become substantially colorless or colorless in a time period ranging from about 1 day to about 3 months.
For example, the solid composition or STTC, in the absence of the colorant stabilizer, can become substantially colorless or colorless in about 1 day, about 2 days, about 3 days, about 4 days, about 5 days, about 6 days, about 1 week, about 2 weeks, about 3 weeks, about 4 weeks, about 5 weeks, about 6 weeks, about 7 weeks, about 8 weeks, about 9 weeks, about 10 weeks, or about 11 weeks.
For example, the composition or STTC, in the absence of the colorant stabilizer, can become substantially colorless or colorless in at least 1 day, at least 2 days, at least 3 days, at least 4 days, at least 5 days, at least 6 days, at least 1 week, at least 2 weeks, at least 3 weeks, at least 4 weeks, at least 5 weeks, at least 6 weeks, at least 7 weeks, at least 8 weeks, at least 9 weeks, at least 10 weeks, at least 11 weeks, or at least 12 weeks.
Colorants employed in the STTC can be, for example, Milliken Liquitint® colorants.

The colorant can be, for example, one or more selected from the group consisting of Acid Blue 80, Acid Red 52, Acid Violet 48, and combinations thereof. When the colorant is one or more of these, the STTC, optionally, does not need to contain a colorant stabilizer. Surprisingly, it has been found that Acid Blue 80, Acid Red 52, and Acid Violet 48, do not display significant discoloration over time in solid compositions, STTCs, or liquid compositions, that do not contain a colorant stabilizer.

In one embodiment, a cationic polymer defined to include polymers which, because of their molecular weight or monomer composition, are soluble or dispersible to at least the extent of 0.01% by weight in distilled water at 25° C. Water soluble cationic polymers can include polymers in which one or more of the constituent monomers are selected from the list of copolymerizable cationic or amphoteric monomers. These monomer units contain a positive charge over at least a portion of the pH range 6-11. A partial listing of monomers can be found in the “International Cosmetic Ingredient Dictionary,” 5th Edition, edited by J. A. Wenninger and G. N. McEwen, The Cosmetic, Toiletry. and Fragrance Association, 1993. Another source of such monomers can be found in “Encyclopedia of Polymers and Thickeners for Cosmetics”, by R. Y. Lochhead and W. R. Fron, Cosmetics & Toiletries, vol. 108, May 1993, pp 95-135.
The cationic polymers of the present invention can be amine salts or quaternary ammonium salts. Preferably the cationic polymers are quarternary ammonium salts. They includes cationic derivatives of natural polymers such as polysaccharide, polyquaternium 10, UCARE Polymer JR-400, UCARE Polymer LR-400, starch and their copolymers with certain cationic synthetic polymers such as polymers and co-polymers of cationic vinylpyridine or vinyl pyridinium chloride.
Specifically, monomers useful in this invention may be represented structurally as etiologically unsaturated compounds as in formula I:
wherein R12 is hydrogen, hydroxyl, methoxy, or a C1 to C30 straight or branched alkyl radical; R13 is hydrogen, or a C1-30 straight or branched alkyl, a C1-30 straight or branched alkyl substituted aryl, aryl substituted C1-30 straight or branched alkyl radical, or a poly oxyalkene condensate of an aliphatic radical; and R14 is a heteroatomic alkyl or aromatic radical containing either one or more quaternized nitrogen atoms or one or more amine groups which possess a positive charge over a portion of the pH interval pH 6 to 11. Such amine groups can be further delineated as having a pKa of about 6 or greater.
Examples of cationic monomers of formula I include, but are not limited to, co-poly 2-vinyl pyridine and its co-poly 2-vinyl N-alkyl quaternary pyridinium salt derivatives; co-poly 4-vinyl pyridine and its co-poly 4-vinyl N-alkyl quaternary pyridinium salt derivatives; co-poly 4-vinylbenzyltrialkylammonium salts such as co-poly 4-vinylbenzyltrimethylammonium salt; co-poly 2-vinyl piperidine and co-poly 2-vinyl piperidinium salt; co-poly 4-vinylpiperidine and co-poly 4-vinyl piperidinium salt; co-poly 3-alkyl 1-vinyl imidazolium salts such as co-poly 3-methyl 1-vinyl imidazolium salt; acrylamido and methacrylamido derivatives such as co-poly dimethyl aminopropylmethacrylamide, co-poly acrylamidopropyl trimethylammonium salt and co-poly methacrylamidopropyl trimethylammonium salt; acrylate and methacrylate derivatives such as co-poly dimethyl aminoethyl (meth)acrylate, co-poly ethanaminium N,N,N trimethyl 2-[(1-oxo-2 propenyl)oxy]-salt, co-poly ethanaminium N,N,N trimethyl 2-[(2 methyl-1-oxo-2 propenyl)oxy]-salt, and co-poly ethanaminium N,N,N ethyl dimethyl 2-[(2 methyl-1-oxo-2 propenyl)oxy]-salt.
Also included among the cationic monomers suitable for this invention are co-poly vinyl amine and co-polyvinylammonium salt; co-poly diallylamine, co-poly methyldiallylamine, and co-poly diallydimethylammonium salt; and the ionene class of internal cationic monomers. This class includes co-poly ethylene imine, co-poly ethoxylated ethylene imine and co-poly quaternized ethoxylated ethylene imine; co-poly [(dimethylimino)trimethylene(dimethylimino)hexamethylene disalt], co-poly [(diethylimino)trimethylene(dimethylimino)trimethylene disalt]; co-poly [(dimethylimino)2-hydroxypropyl salt]; co-polyquartemium-2, co-polyquartemium-17, and co-polyquartemium 18, as defined in the “International Cosmetic Ingredient Dictionary” edited by Wenninger and McEwen.
An additional, and highly preferred class of cationic monomers suitable for this invention are those arising from natural sources and include, but are not limited to, cocodimethylammonium hydroxypropyl oxyethyl cellulose, lauryldimethylammonium hydroxypropyl oxyethyl cellulose, stearyldimethylammonium hydroxypropyl oxyethyl cellulose, and stearyldimethylammonium hydroxyethyl cellulose; guar 2-hydroxy-3-(trimethylammonium)propyl ether salt; and cellulose 2-hydroxyethyl 2-hydroxy 3-(trimethyl ammonio)propyl ether salt.
The counterion of the comprising cationic co-monomer is freely chosen from the halides: chloride, bromide, and iodide; or from hydroxide, phosphate, sulfate, hydrosulfate, ethyl sulfate, methyl sulfate, formate, and acetate.
The weight fraction of the cationic polymer which is composed of the above-described cationic monomer units can range from 1 to 100%, preferably from 10 to 100%, and most preferably from 15 to 80% of the entire polymer. The remaining monomer units comprising the cationic polymer are chosen from the class of anionic monomers and the class of nonionic monomers or solely from the class of nonionic monomers. In the former case, the polymer is an amphoteric polymer while in the latter case it can be a cationic polymer, provided that no amphoteric co-monomers are present. Amphoteric polymers should also be considered within the scope of this disclosure, provided that the polymer unit possesses a net positive charge at one or more points over the wash pH range of pH 6 to 11.
The class of nonionic monomers include, but are not limited to, vinyl alcohol; vinyl acetate; vinyl methyl ether; vinyl ethyl ether; acrylamide, methacrylamide and other modified acrylamides; vinyl propionate; alkyl acrylates (esters of acrylic or methacrylic acid); and hydroxyalkyl acrylate esters. A second class of nonionic monomers include co-poly ethylene oxide, co-poly propylene oxide, and co-poly oxymethylene. A third, and highly preferred, class of nonionic monomers includes naturally derived materials such as hydroxyethylcellulose.
Many of the aforementioned cationic polymers can be synthesized in, and are commercially available in, a number of different molecular weights. In order to achieve optimal cleaning and softening performance from the product, it is desirable that the water-soluble cationic or amphoteric polymer used in this invention be of an appropriate molecular weight. Without wishing to be bound by theory, it is believed that polymers that are too high in mass can entrap soils and prevent them from being removed. The use of cationic polymers with an average molecular weight of less than about 850,000 daltons, and especially those with an average molecular weight of less than 500,000 daltons can help to minimize this effect without significantly reducing the softening performance of properly formulated products. On the other hand, polymers with a molecular weight of about 10,000 daltons or less are believed to be too small to give an effective softening benefit.
In addition, the charge density of the cationic polymer can affect either softening or staining removal. The charge density relates to the degree of cationic substitution, and can be expressed with Nitrogen content of a cationic polymer. Preferred are cationic polymer having a N % from 0.01 to 2.2%, and more preferred are cationic polymers having a N % from 0.2 to 1.6%, and most preferred are cationic polymers having a N % from 0.3 to 1.4%.

The SWCCAs can be included with detergent(s) to form cleaning agent compositions. Cleaning agent compositions are disclosed herein, and SWCCAs can replace or augment STTCs in cleaning agent compositions.
Methods of Use
The SWCCAs can be used to treat textiles (i.e., to impart scent or soften or clean or decrease static build up when the treated textile is subsequently dried). The SWCCAs can be used in a top loading or front loading washer. The SWCCAs can be used in hot, warm, or cold water. The SWCCAs can be used with a detergent in a wash cycle, or separately but in conjunction with a detergent (e.g., in a separate wash or rinse cycle). The SWCCAs can be used in cleaning agent compositions. The textiles treated with the SWCCAs (or STTCs) can, optionally, be in need of treatment.
Methods of Making SWCCAs
The SWCCAs can be made by any known method. The SWCCAs can be made, for example, by heating the non-ionic surfactant(s) (optionally in the presence of one or two or three or four or five or all of the ingredients in the SWCCA) until the non-ionic surfactant(s) melt and then adding and/or mixing the additional ingredients.
In some embodiments, the non-ionic surfactant(s) are blended with the fabric conditioning agent(s) and the plasticizer(s), heated to form a melt, and optionally mixed. Then, additional ingredients such as colorant(s), colorant stabilizer(s), or fragrance(s) are optionally added and blended. The blends are allowed to cool. Optionally, the heated blends are added repeatedly in small portions as drops to a polymeric film and then allowed to cool and optionally removed from the polymeric film, thereby forming pastilles.
In some embodiments, the SWCCAs can be in the form of tablets, which can be unit doses. To make these, for example, the ingredients in the SWCCAs are blended together, for example, at room temperature, and compressed to form tablets. For larger tablets, it is preferred to add a disintegrant to the mixture of ingredients prior to compressing the mixture into tablets. The blends can be, for example, dry powder blends.
The tableting can occur using any known tablet press, for example, a rotary tablet press. The tableting compression force can range, for example, from about 1,000 pounds to about 15,000 pounds. The tableting compression force can be, for example, about 2,000 pounds, about 3,000 pounds, about 4,000 pounds, about 5,000 pounds, about 6,000 pounds, about 7,000 pounds, about 8,000 pounds, about 9,000 pounds, about 10,000 pounds, about 11,000 pounds, about 12,000 pounds, about 13,000 pounds, or about 14,000 pounds.

The following examples are illustrative and do not limit the scope of the disclosure of the claims.
13 g of polyethylene glycol 8000 (“PEG 8000”) were melted in a heated container equipped with a stirring apparatus. 0.25 g of citric acid, 2.25 g of perfume (Mayflowers TD 485531 EB (Firmenich)), and 0.00650 g of Milliken Liquitint® Royal MC colorant were added to the melted PEG 8000, with stirring, to create a homogenously mixed molten coating mixture.
The molten coating mixture was poured onto 79.494 g of Kleer Salt (Morton) granules. The salt granules and melted coating mixture were agitated, thereby producing coated salt granules.
The coated salt granules were then cooled such that the coating remained tacky, and the 5.00 g of sodium sulfate powder were applied to the exterior coating surface of the coated granules to produce a solid textile-treating composition.
13 g of polyethylene glycol 8000 (“PEG 8000”) were melted in a heated container equipped with a stirring apparatus. 0.25 g of citric acid, 2.40 g of perfume (High Five ACM 190991 (Firmenich)), and 0.00650 g of Milliken Liquitint® Royal MC colorant were added to the melted PEG 8000, with stirring, to create a homogenously mixed molten coating mixture.
The molten coating mixture was poured onto 79.354 g of pretzel salt (Morton) granules. The salt granules and melted coating mixture were agitated, thereby producing coated salt granules.
The coated salt granules were then cooled such that the coating remained tacky, and the 2.75 g of sodium sulfate and 2.24 grams of the cationic polymer UCARE LR-400, a cationic HEC polymer, were applied to the exterior coating surface of the coated granules to produce a solid textile-treating composition.
A block copolymer (PLURONIC F-38) was mixed with a fabric condition agent (ARMOSOFT TWS-1) and a plasticizer mixture (glyceryl monostearate and PEG-100 monostearate) and the mixture was heated to about 133° F. The mixture melted. A colorant and a perfume were added to the melted mixture, mixing is effected, and the mixture was then dropped repeatedly in small portions onto a polymeric film to form drops. The drops were hardened to form pastilles, which were then removed from the polymeric film. The amounts of ingredients blended together (Formulae 1-3) are presented in the table, below (QA means quality adjusted with color and fragrance to make 100% by weight of the formula):
Polyethylene glycol 200, glycerin, and ARMOSOFT TWS-1 were mixed together with heating. After approximately 10 minutes, water, a colorant, and a perfume were added. The resulting solutions were allowed to cool to room temperature. The contents of the LTTC formulations are presented in the table, below (QA means quality adjusted with color and fragrance to make 100% by weight of the formula):
Unit dose tablets were prepared by compressing, with 9000 pounds of force, the following ingredients, to form the tablets:
24 Tablets in total were made. Each tablet weight about 17 g.
A representative tablet was tested for ability to dissolve in water as follows: a 17 gram tablet was placed in 700 g of water having a temperature of 68 degrees F. The tablet dissolved in 2 minutes and 15 seconds.
Unit dose packets of fragrance booster STTCs were prepared by mixing the following ingredients:
In a related formulation, unit dose packets of fragrance booster were prepared by mixing the following ingredients:
Following formulation, the fragrance delivery STTCs were packaged into single-chamber PVOH film packets using the Cloud machinery and methodology as described elsewhere herein. In related such embodiments, the fragrance delivery STTCs were included in unit dose containers also containing detergent-containing formulations. These unit dose STTCs are suitable for delivery of fragrance to fabrics by including the unit dose STTCs with the clothing in the wash chamber at the beginning of the wash cycle.
A Phabrometer Instrument, manufactured by Nucybertek, was employed to test to softening ability.
12 knitted cotton replicate fabric pieces (disc shaped) were created from 4 independent fabric swatches. Five pounds of ballast were included for each wash of the swatches. The swatches (3 reps per fabric swatch) and ballast were washed in cells using All Free Clear detergent. ARMOSOFT-TWS-1 containing formulations were added to the wash cycle of cells 1-3 but not added to cell 4 (control cell). Terry towels were also included in the wash cells for subjective testing.
The following is the amount of ARMOSOFT-TWS-1 in the formulations in % by weight, based on the total weight of the formulations:
The settings for each cell were as follows:
After each run, the washed towels were dried for 60 minutes. The dry swatches were evaluated in the Phabrometer by being individually weighed down and forced through an orifice while measuring and/or calculating hand attributes (e.g., softness).
Response softness was found to be as follows base on weight % of ARMOSOFT-TWS-1 in the formulation:
Levels not connected by the same letter are significantly different.
The results indicate that 20% inclusion of ARMOSOFT-TWS-1 showed a statistically difference in softening as perceived by the Phabrometer. The 15% inclusion level showed a trend of improved softening but was not statistically different than untreated. The 10% inclusion level did not show any softening response by the Phabrometer.
