Patent Application
20160090555
The present invention relates to cleaning and/or treatment compositions comprising malodor reduction compositions and methods of making and using such cleaning and/or treatment compositions and malodor reduction compositions.
Unscented or scented products are desired by consumers as they may be considered more natural and discreet than scented products. Manufacturers of unscented or scented products for controlling malodors rely on malodor reduction ingredients or other technologies (e.g. filters) to reduce malodors. However, effectively controlling malodors, for example, amine-based malodors (e.g. fish and urine), thiol and sulfide-based malodors (e.g. garlic and onion), C2-C12 carboxylic acid based malodors (e.g. body and pet odor), indole based malodors (e.g. fecal and bad breath), short chain fatty aldehyde based malodors (e.g. grease) and geosmin based malodors (e.g. mold/mildew) may be difficult, and the time required for a product to noticeably reduce malodors may create consumer doubt as to the product's efficacy on malodors. Often times, manufacturers incorporate scented perfumes to help mask these difficult malodors.
Unfortunately, malodor control technologies typically cover up the malodor with a stronger scent and thus interfere with the scent of the perfumed or unperfumed situs that is treated with the malodor control technology. Thus, limited nature of the current malodor control technologies is extremely constraining. Thus what is needed is a broader palette of malodor control technologies so the perfume community can deliver the desired level of character in a greater number of situations/applications. Surprisingly, Applicants recognized that in addition to blocking a malodor's access to a sensory cell, in order to achieve the desired goal, a malodor control technology must leave such sensor cell open to other molecules, for example scent molecules. As a result, such malodor reduction compositions do not unduely interfere with the scent of the perfumed or unperfumed cleaning and/or treatment compositions that comprise such compositions and the perfumed or unperfumed situs that is treated with such cleaning and/or treatment compositions.
The present invention relates to cleaning and/or treatment compositions comprising malodor reduction compositions and methods of making and using such cleaning and/or treatment products and malodor reduction compositions. As a result, such malodor reduction compositions do not unduely interfere with the scent of the perfumed or unperfumed cleaning and/or treatment compositions that comprise such compositions and the perfumed or unperfumed situs that is treated with such cleaning and/or treatment compositions.
As used herein “MORV” is the calculated malodor reduction value for a subject material. A material's MORV indicates such material's ability to decrease or even eliminate the perception of one or more malodors. For purposes of the present application, a material's MORV is calculated in accordance with method found in the test methods section of the present application.
As used herein, the term “perfume” does not include malodor reduction materials. Thus, the perfume portion of a composition does not include, when determining the perfume's composition, any malodor reduction materials found in the composition as such malodor reduction materials are described herein. In short, if a material has a malodor reduction value “MORV” that is within the range of the MORV recited in the subject claim, such material is a malodor reduction material for purposes of such claim.
As used herein “cleaning and/or treatment compositions” means products comprising fluid laundry detergents, fabric enhancers, laundry and/or rinse additives, fluid dishwashing detergents, fluid hard surface cleaning and/or treatment compositions, fluid toilet bowl cleaners that may or may not be contained in a unit dose delivery product all for consumer, agricultural, industrial or institutional use.
As used herein, “malodor” refers to compounds generally offensive or unpleasant to most people, such as the complex odors associated with bowel movements.
As used herein, “odor blocking” refers to the ability of a compound to dull the human sense of smell.
As used herein, the terms “a” and “an” mean “at least one”.
As used herein, the terms “include”, “includes” and “including” are meant to be non-limiting.
Unless otherwise noted, all component or composition levels are in reference to the active portion of that component or composition, and are exclusive of impurities, for example, residual solvents or by-products, which may be present in commercially available sources of such components or compositions.
All percentages and ratios are calculated by weight unless otherwise indicated. All percentages and ratios are calculated based on the total composition unless otherwise indicated.
It should be understood that every maximum numerical limitation given throughout this specification includes every lower numerical limitation, as if such lower numerical limitations were expressly written herein. Every minimum numerical limitation given throughout this specification will include every higher numerical limitation, as if such higher numerical limitations were expressly written herein. Every numerical range given throughout this specification will include every narrower numerical range that falls within such broader numerical range, as if such narrower numerical ranges were all expressly written herein.
A non-limiting set of suitable malodor reduction materials are provided in the tables below. For ease of use, each material in Tables 1-3 is assigned a numerical identifier which is found in the column for each table that is designated Number. Table 4 is a subset of Table 1, Table 5 is a subset of Table 2 and Table 6 is a subset of Table 3 and there for Tables 4, 5 and 6 each use the same numerical identifier as found, respectively, in Tables 1-3.
A=Vapor Pressure >0.1 torr
B=Vapor Pressure is between 0.01 torr and 0.1 torr
G=Odor Detection Threshold less than p.ol=8
H=Odor Detection Threshold greater than p.ol=8
I=Melamine formaldehyde PMC Headspace Response Ratio greater than or equal to 10
J=Melamine formaldehyde PMC leakage less than or equal to 5%
K=Log of liquid dish neat product liquid-air partition coefficient greater than or equal to −7
L=Log of liquid dish neat product liquid-air partition coefficient greater than or equal to −5
The materials in Tables 1-6 can be supplied by one or more of the following:
Firmenich Inc. of Plainsboro N.J. USA; International Flavor and Fragrance Inc. New York, N.Y. USA; Takasago Corp. Teterboro, N.J. USA; Symrise Inc. Teterboro, N.J. USA; Sigma-Aldrich/SAFC Inc. Carlsbad, Calif. USA; and Bedoukian Research Inc. Danbury, Conn. USA.
Actual MORV values for each material listed in Tables 1-6 above are as follows:
Cleaning and/or Treatment Composition and Methods
A cleaning and/or treatment composition having a viscosity of from about 10 mPa·s to about 50,000 mPa·s, preferably from about 50 mPa·s to about 2000 mPa·s, most preferably from about 75 mPa·s to about 400 mPa·s, a pH from about 3 to about 10, preferably from about 4 to about 8, most preferably from about 5 to about 8, said composition comprising, based on total cleaning and/or treatment composition weight,
In one aspect of Applicants' cleaning and/or treatment composition:
In one aspect of Applicants' cleaning and/or treatment composition, said malodor reduction materials have a Fragrance Fidelity Index of less than 3, preferably less than 2, more preferably less than 1 and most preferably 0 and/or a Fragrance Fidelity Index average of 3 to about 0.001 Fragrance Fidelity Index. As the Fragrance Fidelity Index decreases, the malodor reduction material(s) provide less and less of a scent impact, while continuing to counteract malodors.
In one aspect of Applicants' cleaning and/or treatment composition, said cleaning and/or treatment composition comprises a perfume and has a weight ratio of parts of malodor reduction composition to parts of perfume of from about 1:20,000 to about 3000:1, preferably from about 1:10,000 to about 1,000:1, more preferably 5,000:1 to about 500:1 and most preferably from about 1:15 to about 1:1. As the ratio of malodor reduction composition to parts of perfume is tightened, the malodor reduction material(s) provide less and less of a scent impact, while continuing to counteract malodors.
In one aspect of said cleaning and/or treatment composition, said cleaning and/or treatment composition comprises one or more malodor reduction materials having a log P greater than 3, preferably greater than 3 but less than 8, preferably said one or more malodor reduction materials are selected from the group consisting of Table 1 materials 1;

Nonionic fabric care benefit agents can comprise sucrose esters, and are typically derived from sucrose and fatty acids. Sucrose ester is composed of a sucrose moiety having one or more of its hydroxyl groups esterified.
Sucrose is a disaccharide having the following formula:
Alternatively, the sucrose molecule can be represented by the formula: M(OH)8, wherein M is the disaccharide backbone and there are total of 8 hydroxyl groups in the molecule.
Thus, sucrose esters can be represented by the following formula:
M(OH)8-x(OC(O)R1)x
wherein x is the number of hydroxyl groups that are esterified, whereas (8-x) is the hydroxyl groups that remain unchanged; x is an integer selected from 1 to 8, alternatively from 2 to 8, alternatively from 3 to 8, or from 4 to 8; and R1 moieties are independently selected from C1-C22 alkyl or C1-C30 alkoxy, linear or branched, cyclic or acyclic, saturated or unsaturated, substituted or unsubstituted.
In one embodiment, the R1 moieties comprise linear alkyl or alkoxy moieties having independently selected and varying chain length. For example, R1 may comprise a mixture of linear alkyl or alkoxy moieties wherein greater than about 20% of the linear chains are C18, alternatively greater than about 50% of the linear chains are C18, alternatively greater than about 80% of the linear chains are C18.
In another embodiment, the R1 moieties comprise a mixture of saturate and unsaturated alkyl or alkoxy moieties; the degree of unsaturation can be measured by “Iodine Value” (hereinafter referred as “IV”, as measured by the standard AOCS method). The IV of the sucrose esters suitable for use herein ranges from about 1 to about 150, or from about 2 to about 100, or from about 5 to about 85. The R1 moieties may be hydrogenated to reduce the degree of unsaturation. In the case where a higher IV is preferred, such as from about 40 to about 95, then oleic acid and fatty acids derived from soybean oil and canola oil are the starting materials.
In a further embodiment, the unsaturated R1 moieties may comprise a mixture of “cis” and “trans” forms about the unsaturated sites. The “cis”/“trans” ratios may range from about 1:1 to about 50:1, or from about 2:1 to about 40:1, or from about 3:1 to about 30:1, or from about 4:1 to about 20:1.
Generally, all dispersible polyolefins that provide fabric care benefits can be used as water insoluble fabric care benefit agents in the present invention. The polyolefins can be in the format of waxes, emulsions, dispersions or suspensions. Non-limiting examples are discussed below.
In one embodiment, the polyolefin is chosen from a polyethylene, polypropylene, or a combination thereof. The polyolefin may be at least partially modified to contain various functional groups, such as carboxyl, alkylamide, sulfonic acid or amide groups. In another embodiment, the polyolefin is at least partially carboxyl modified or, in other words, oxidized.
For ease of formulation, the dispersible polyolefin may be introduced as a suspension or an emulsion of polyolefin dispersed by use of an emulsifying agent. The polyolefin suspension or emulsion may comprise from about 1% to about 60%, alternatively from about 10% to about 55%, alternatively from about 20% to about 50% by weight of polyolefin. The polyolefin may have a wax dropping point (see ASTM D3954-94, volume 15.04—“Standard Test Method for Dropping Point of Waxes”) from about 20° to about 170° C., alternatively from about 50° to about 140° C. Suitable polyethylene waxes are available commercially from suppliers including but not limited to Honeywell (A-C polyethylene), Clariant (Velustrol® emulsion), and BASF (LUWAX®).
When an emulsion is employed with the dispersible polyolefin, the emulsifier may be any suitable emulsification agent. Non-limiting examples include an anionic, cationic, nonionic surfactant, or a combination thereof. However, almost any suitable surfactant or suspending agent may be employed as the emulsification agent. The dispersible polyolefin is dispersed by use of an emulsification agent in a ratio to polyolefin wax of about 1:100 to about 1:2, alternatively from about 1:50 to about 1:5, respectively.
Polymer Latexes
Polymer latex is made by an emulsion polymerization which includes one or more monomers, one or more emulsifiers, an initiator, and other components familiar to those of ordinary skill in the art. Generally, all polymer latexes that provide fabric care benefits can be used as water insoluble fabric care benefit agents of the present invention. Additional non-limiting examples include the monomers used in producing polymer latexes such as: (1) 100% or pure butylacrylate; (2) butylacrylate and butadiene mixtures with at least 20% (weight monomer ratio) of butylacrylate; (3) butylacrylate and less than 20% (weight monomer ratio) of other monomers excluding butadiene; (4) alkylacrylate with an alkyl carbon chain at or greater than C6; (5) alkylacrylate with an alkyl carbon chain at or greater than C6 and less than 50% (weight monomer ratio) of other monomers; (6) a third monomer (less than 20% weight monomer ratio) added into an aforementioned monomer systems; and (7) combinations thereof.

Suitable emulsifiers include anionic, cationic, nonionic and amphoteric surfactants. Suitable initiators include initiators that are suitable for emulsion polymerization of polymer latexes. The particle size diameter (χ50) of the polymer latexes can be from about 1 nm to about 10 μm, alternatively from about 10 nm to about 1 μm, or even from about 10 nm to about 20 nm.
Fatty Acid
One aspect of the invention provides a fabric softening composition comprising a fatty acid, such as a free fatty acid. The term “fatty acid” is used herein in the broadest sense to include unprotonated or protonated forms of a fatty acid; and includes fatty acid that is bound or unbound to another chemical moiety as well as the various combinations of these species of fatty acid. One skilled in the art will readily appreciate that the pH of an aqueous composition will dictate, in part, whether a fatty acid is protonated or unprotonated. In another embodiment, the fatty acid is in its unprotonated, or salt form, together with a counter ion, such as, but not limited to, calcium, magnesium, sodium, potassium and the like. The term “free fatty acid” means a fatty acid that is not bound to another chemical moiety (covalently or otherwise) to another chemical moiety.
In one embodiment, the fatty acid may include those containing from about 12 to about 25, from about 13 to about 22, or even from about 16 to about 20, total carbon atoms, with the fatty moiety containing from about 10 to about 22, from about 12 to about 18, or even from about 14 (mid-cut) to about 18 carbon atoms.
The fatty acids of the present invention may be derived from (1) an animal fat, and/or a partially hydrogenated animal fat, such as beef tallow, lard, etc.; (2) a vegetable oil, and/or a partially hydrogenated vegetable oil such as canola oil, safflower oil, peanut oil, sunflower oil, sesame seed oil, rapeseed oil, cottonseed oil, corn oil, soybean oil, tall oil, rice bran oil, palm oil, palm kernel oil, coconut oil, other tropical palm oils, linseed oil, tung oil, etc.; (3) processed and/or bodied oils, such as linseed oil or tung oil via thermal, pressure, alkali-isomerization and catalytic treatments; (4) a mixture thereof, to yield saturated (e.g. stearic acid), unsaturated (e.g. oleic acid), polyunsaturated (linoleic acid), branched (e.g. isostearic acid) or cyclic (e.g. saturated or unsaturated α-disubstituted cyclopentyl or cyclohexyl derivatives of polyunsaturated acids) fatty acids.
Mixtures of fatty acids from different fat sources can be used.
In one aspect, at least a majority of the fatty acid that is present in the fabric softening composition of the present invention is unsaturated, e.g., from about 40% to 100%, from about 55% to about 99%, or even from about 60% to about 98%, by weight of the total weight of the fatty acid present in the composition, although fully saturated and partially saturated fatty acids can be used. As such, the total level of polyunsaturated fatty acids (TPU) of the total fatty acid of the inventive composition may be from about 0% to about 75% by weight of the total weight of the fatty acid present in the composition.
The cis/trans ratio for the unsaturated fatty acids may be important, with the cis/trans ratio (of the C18:1 material) being from at least about 1:1, at least about 3:1, from about 4:1 or even from about 9:1 or higher.
Branched fatty acids such as isostearic acid are also suitable since they may be more stable with respect to oxidation and the resulting degradation of color and odor quality.
The Iodine Value or “IV” measures the degree of unsaturation in the fatty acid. In one embodiment of the invention, the fatty acid has an IV from about 10 to about 140, from about 15 to about 100 or even from about 15 to about 60.
Another class of fatty ester fabric care actives is softening oils, which include but are not limited to, vegetable oils (such as soybean, sunflower, and canola), hydrocarbon based oils (natural and synthetic petroleum lubricants, in one aspect polyolefins, isoparaffins, and cyclic paraffins), triolein, fatty esters, fatty alcohols, fatty amines, fatty amides, and fatty ester amines. Oils can be combined with fatty acid softening agents, clays, and silicones.

Suitable levels of silicone may comprise from about 0.1% to about 70%, alternatively from about 0.3% to about 40%, alternatively from about 0.5% to about 30%, alternatively from about 1% to about 20% by weight of the composition. Useful silicones can be any silicone comprising compound. In one embodiment, the silicone polymer is selected from the group consisting of cyclic silicones, polydimethylsiloxanes, aminosilicones, cationic silicones, silicone polyethers, silicone resins, silicone urethanes, and mixtures thereof. In one embodiment, the silicone is a polydialkylsilicone, alternatively a polydimethyl silicone (polydimethyl siloxane or “PDMS”), or a derivative thereof. In another embodiment, the silicone is chosen from an aminofunctional silicone, amino-polyether silicone, alkyloxylated silicone, cationic silicone, ethoxylated silicone, propoxylated silicone, ethoxylated/propoxylated silicone, quaternary silicone, or combinations thereof.

In order to conduct the calculations involved in the computed-value test methods described herein, the starting information required includes the identity, weight percent, and molar percent of each PRM in the perfume being tested, as a proportion of that perfume, wherein all PRMs in the perfume composition are included in the calculations. Additionally for each of those PRMs, the molecular structure, and the values of various computationally-derived molecular descriptors are also required, as determined in accordance with the Test Method for the Generation of Molecular Descriptors described herein.
For each PRM in a perfume mixture or composition, its molecular structure is used to compute various molecular descriptors. The molecular structure is determined by the graphic molecular structure representations provided by the Chemical Abstract Service (“CAS”), a division of the American Chemical Society, Columbus, Ohio, U.S.A. These molecular structures may be obtained from the CAS Chemical Registry System database by looking up the index name or CAS number of each PRM. For PRMs, which at the time of their testing are not yet listed in the CAS Chemical Registry System database, other databases or information sources may be used to determine their structures. For a PRM which has potentially more than one isomer present, the molecular descriptor computations are conducted using the molecular structure of only one of the isomers, which is selected to represent that PRM. The selection of isomer is determined by the relative amount of extension in the molecular structures of the isomers. Of all the isomers of a given PRM, it is the isomer whose molecular structure that is the most prevalent which is the one that is selected to represent that PRM. The structures for other potential isomers of that PRM are excluded from the computations. The molecular structure of the isomer that is the most prevalent is paired with the concentration of that PRM, where the concentration reflects the presence of all the isomers of that PRM that are present.
A molecule editor or molecular sketching software program, such as ChemDraw (CambridgeSoft/PerkinElmer Inc., Waltham, Mass., U.S.A.), is used to duplicate the 2-dimensional molecular structure representing each PRM. Molecular structures should be represented as neutral species (quaternary nitrogen atoms are allowed) with no disconnected fragments (e.g., single structures with no counter ions). The winMolconn program described below can convert any deprotonated functional groups to the neutral form by adding the appropriate number of hydrogen atoms and will discard the counter ion.
For each PRM, the molecular sketching software is used to generate a file which describes the molecular structure of the PRM. The file(s) describing the molecular structures of the PRMs is subsequently submitted to the computer software program winMolconn, version 1.0.1.3 (Hall Associates Consulting, Quincy, Mass., U.S.A., www.molconn.com), in order to derive various molecular descriptors for each PRM. As such, it is the winMolconn software program which dictates the structure notations and file formats that are acceptable options. These options include either a MACCS SDF formatted file (i.e., a Structure-Data File); or a Simplified Molecular Input Line Entry Specification (i.e., a SMILES string structure line notation) which is commonly used within a simple text file, often with a “.smi” or “.txt” file name extension. The SDF file represents each molecular structure in the format of a multi-line record, while the syntax for a SMILES structure is a single line of text with no white space. A structure name or identifier can be added to the SMILES string by including it on the same line following the SMILES string and separated by a space, e.g.: C1=CC═CC=C1 benzene.
The winMolconn software program is used to generate numerous molecular descriptors for each PRM, which are then output in a table format. Specific molecular descriptors derived by winMolconn are subsequently used as inputs (i.e., as variable terms in mathematical equations) for a variety of computer model test methods in order to calculate values such as: saturation Vapour Pressure (VP); Boiling Point (BP); logarithm of the Octanol/Water Partition Coefficient (log P); Odour Detection Threshold (ODT); Malodour Reduction Value (MORV); and/or Universal Malodour Reduction Value (Universal MORV) for each PRM. The molecular descriptor labels used in the models' test method computations are the same labels reported by the winMolconn program, and their descriptions and definitions can be found listed in the winMolconn documentation. The following is a generic description of how to execute the winMolconn software program and generate the required molecular structure descriptors for each PRM in a composition.

Blocker materials suitable for use in cleaning and/or treatment compositions of the present invention are chosen for their ability to decrease malodor, while not interfering with perception of a fragrance. Material selection is done by assigning two indices to a test sample material from two reference scales in order to rank odor strengths. The two reference scales are the Fragrance Fidelity Index (FFI) scale and the Blocker Index (BI) scale. The FFI ranks the ability of the test sample material to impart a perceivable odor which could cause interference when combined with another fragrance and the BI ranks the ability of the test sample material to reduce malodor perception. The two methods for assigning the indices to a test sample on the FFI and the BI reference scales are given below.
The first step in the method for assigning an FFI to the test samples on the FFI reference scale is to create the FFI reference swatches. The swatches for the scale are created by treating clean fabrics swatches with a known amount of a known concentration of an ethyl vanillin solution. Fabric swatches for this test are white knit polycotton (4 inch×4 inch) swatches from EMC ordered as PC 50/50. The supplier is instructed to strip the swatches first, stripping involves washing twice with a fragrance-free detergent and rinsing three times.
Make three solutions of ethyl vanillin using a 50%/50% EtOH/water as the diluent at the following concentrations: 25 ppm, 120 ppm and 1000 ppm. Pipette 13 μL of each of the three solutions into the middle of a clean swatch resulting in about a 1 cm diameter of the solution in the middle of the swatch. This will create a sensory scale of three swatches with three different odor levels based on the concentration of the solution pipetted onto the swatch. After drying for 30 minutes in a vented hood, the swatches are wrapped in aluminum foil to prevent odor contamination to the treated swatch. A clean untreated swatch is also included as the lowest anchor point of reference for odor strength on the FFI scale. The FFI reference scale swatches should be used within 0.5 to 12 hours and discarded after 12 hours. The swatches are used as scale anchor points when graders evaluate a test sample(s) and are assigned a Fragrance Fidelity Index (FFI) as show in Table 7.
At least four perfumers/expert graders are used to rank the ethyl vanillin swatches in the FFI scale. The perfumer/expert grader needs to demonstrate adequate discrimination on the scale. The perfumer/expert panel is asked to rank order swatches according to a scale between 0 and 3. The panel must demonstrate statistical differences between the swatches as seen in Table 7.
The expert graders must demonstrate a full range of 2.5 over the 4 swatches to be acceptably discriminating. Grader 2 in table 1 has a range of only 2 and is eliminated from the panel. The panel of expert graders must also demonstrated the ability to statistically discriminate between swatches in the scale.
The reference swatches represent the 0, 1, 2, and 3 FFIs on the FFI reference scale, Table 9. The expert grader should familiarize them self with the strength of the odor on the FFI reference swatches by sniffing each one starting at 0 (the lowest odor strength) and ending at 3 (the highest odor strength). This should be done prior to evaluating the test sample material treated swatch.
Making Swatches Treated with the Test Material
A clean swatch is treated with 13 μL of a known concentration of a test sample material resulting in an about 1 cm of the solution on the clean swatch. Just like the reference swatches, the test sample material swatch is dried in a vented hood for 30 minutes and then wrapped in aluminum foil to prevent contamination. The test material swatches and the FFI reference swatches should be made within 2 hrs of each other. The test material swatch must be used within 0.5 to 12 hours and discarded after 12 hours.
At least two perfumers/expert graders are used to assign an FFI grade to a test sample. The perfumer/expert grader smells the test sample swatch by holding that swatch 1 inch from their nose with their nose centered over the area where the test sample was pipetted on to the fabric and then assigns the test sample an FFI grade using the FFI reference scale anchor swatches as references. The test sample swatch is assigned an FFI grade at or between numbers on the FFI scale shown in Table 9. In cases where the test sample material is graded greater than 3, the test material is not a blocker material or the concentration of the material needs to be lowered and reevaluated to determine if a lower level has a malodor blocker functionality.
The first step in the method for assigning a BI to a test sample material on the BI reference scale is to create the BI reference swatches. The swatches for the scale are created by treating clean fabrics swatches with a known amount of a known volume of isovaleric acid solution at a known concentration. Fabric swatches for this test are white knit polycotton (4 inch×4 inch) swatches from EMC ordered as PC 50/50. The supplier is instructed to strip the swatches first, stripping involves washing twice with a fragrance-free detergent and rinsing three times.
Make one solution of 0.08% isovaleric acid using 50%/50% EtOH/water as the diluent. The BI scale contains one clean swatch with no malodor applied. Three other swatches each have a different volume of the 0.08% isovaleric acid applied. Pipette 2 μL of the 0.08% isovaleric acid solution to one clean swatch, 5 μL of the 0.08% isovaleric acid solution to the next swatch and 20 μL of isovaleric acid to the final clean swatch. These solutions are pipetted to the middle of the swatches. This will create a sensory scale of three swatches with three different odor levels based on the volume of the 0.08% isovaleric acid solution pipetted onto the swatch. After drying for 30 minutes in a vented hood, the swatches are wrapped in aluminum foil to prevent odor contamination to the treated swatch. A clean untreated swatch is also included as the lowest anchor point of reference for malodor strength on the BI scale. The BI reference scale swatches should be used within 0.5 to 12 hours and discarded after 12 hours. The swatches are used as scale anchor points when graders evaluate a test sample(s) and are assigned a Blocker Index (BI) as show in Table 12.
At least four perfumers/expert graders are used to rank the isovaleric acid swatches in the BI scale. The perfumer/expert grader needs to demonstrate adequate discrimination on the scale. The perfumer/expert grader is asked to rank order swatches according to a scale between 0 and 3. The panel of graders must demonstrate statistical differences between the swatches as seen in Table 10.
The expert graders must demonstrate a full range of 2.5 over the 4 swatches to be acceptably discriminating. The panel of expert graders must also demonstrated the ability to statistically discriminate between swatches in the scale. Expert grader #2 did not demonstrate the ability to discriminate between the swatches and is eliminated from the panel, see Table 11.
The reference swatches represent the 0, 1, 2, and 3 BIs on the BI reference scale, Table 12. The expert grader should familiarizes him/herself with the strength of the odor on the BI reference swatches by sniffing each one starting at 0 (the lowest odor strength) and ending at 3 (the highest odor strength). This should be done prior to evaluating the swatch treated with the test material.
Making the Malodorous Swatch and Treating it with a Test Material
To evaluate the BI, the test material is applied to a malodorous swatch to determine how well the test material blocks the malodor. The malodorous swatch is made by treating a clean swatch with 20 μL of a 0.08% solution of isovaleric acid. Dry the malodorous swatch treated with isovaleric acid in a vented hood for 30 minutes. After drying the malodorous swatch a known concentration of test material solution, between 1 ppm and 100 ppm is pipetted onto the malodorous swatch. Apply the test material solution right on top of the spot where the isovaleric acid solution was applied making an about 1 cm diameter spot. Just like the BI reference swatches, the isovaleric acid+test material swatch is dried in a vented hood for 30 minutes and then wrapped in aluminum foil to prevent contamination. The isovaleric acid+test material swatches and the BI reference swatches should be made within 2 hours of each other. The isovaleric acid+test material swatch must be used between 1-12 hours just like the reference swatches. It is sometimes necessary to evaluate several levels of the test material between about 1 and about 100 ppm to determine the BI.
At least two perfumers/expert graders are used to assign the BI to the test sample. The expert grader smells the isovaleric acid+test material swatch by holding that swatch one inch from their nose with their nose centered over the area where the test sample was pipetted on to the fabric and then assigns the isovaleric acid+test material swatch a BI based on ranking its odor strength against the odor strength of the swatches in the BI reference scale. The test sample swatch is assigned a BI at or between numbers on the BI in table. In cases where the isovaleric acid+test material swatch odor is greater than 3 on the BI reference scale, this indicates the material is not a blocker or the concentration of the test material needs to be lowered to achieve its blocker functionality.

Method for Evaluating the Through-the-Wash Malodor Reducing Efficacy of a Malodor Reduction Compound or Composition Incorporated into a Detergent.
This method is intended to evaluate the ability of a malodor control compound to deposit on fabric TTW and reduce the impact of the smell of the malodor without contributing a high level of fragrance odor at the end of the wash process and at the end of the drying process.
The malodorous soil composition comprises bacon grease purchased from EMC (Empirical Manufacturing Group, Cincinnati, Ohio) as well as squalene and Skatole, both purchased from Sigma Aldrich. Bacon grease and squalene comprise malodor models (aldehydes and acids similar to residual body and food odors) and also contributes to the substantivity similar to the role residual body soil is believed to play on consumer garments. Skatole is a good model material for potent body odors. The malodorous soil composition comprises 1.15% of Skatole in a 50%/50% by weight matrix of bacon grease and squalene. To make the malodorous melt bacon grease and weight an aliquot into a beaker. Add an equal weight aliquot of squalene to the bacon grease and stir to combine. For every 98.85 g of bacon grease+squalene mixture add 1.15 g of solid Skatole and stir until the Skatole dissolves. Store the malodorous soil in refrigerator below 10 C. to preserve it. Warm the malodorous soil gently to room temperature prior to adding it to swatches to create the malodorous soiled swatches.
Purchase white knit polycotton (4 inch×4 inch) swatches from EMC. Order PC 50/50 with instructions to EMC to strip fabrics with Downy. Gently warm the malodorous soil composition and pipet 13 uL of the malodorous soil composition onto the polycotton swatches. Stack malodorous soiled swatches with tin foil separating the swatches and seal the stack of swatches in a Mylar bag. Let the swatches treated with the malodorous soil sit at least 16 hours before proceeding to the next step. Use swatches within 60 hours of making.
Prepare the ballast used in washing the malodorous stained swatches. Purchase terry towel ballast is from Standard Textile Cincinnati, Ohio Inc. Strip the ballast using a Kenmore 600 North American top load washing machine by running the ballast twice through the wash/rinse cycles at 60° C. and 7 gpg water (2) with a 1562.5 ppm dose of AATCC Regular Detergent (purchased from American Assoc. of Textile Chemists and Colorists, Research Triangle Park, N.C.) and then 3× wash/rinse cycles at 60° C. 7 gpg with NIL detergent.
Run a test where malodorous soiled swatches are washed with AATCC comprising a malodor reducing compositions that fall within the boundaries of EXAMPLES 1-3 above. Include a control product which has NIL perfume and NIL malodor control compound or composition. Also run a test where the same detergent formulation comprises a malodor control compound or composition. Wash 2 of the malodorous swatches in each test leg and wrap these in aluminum foil. Dry the rest of the ballast and swatches. After drying extract 2 each of the malodorous swatches from each test leg. A perfumer/expert grader smells both the wet swatches and the dry swatches for malodor and perfume and grades these on a 100 pt scale with a higher number representing stronger intensity. The desired outcome is to lower both the intensity of malodor, while still maintaining a lower fragrance intensity.
In the table below, zeros for the dry fabric perfume level shows that the malodor reduction composition delivered no fragrance of its own to the dry fabrics, indicating it is very unlikely to shift the character or raise the intensity of any fragrance added to a detergent having that malodor reducing composition. On the other hand, these compositions did lower the impression of the residual malodor on the malodor stained swatches. This further demonstrates that malodor reducing compositions having at least one component with log P≧3 will deposit though the wash of their own accord and without the need for an additional delivery agent to bring these to the surface of the soiled fabric.
In one aspect of the invention it is preferred that the malodor reduction compound or composition be surface active enough to deposition on fabric through the wash without the aid of a deposition agent. This is achieved by selecting a malodor reducing component with log P≧3 or making a malodor reducing composition comprising at least one malodor reducing component with log P≧3. The following analytical method demonstrates that Amber Core, a malodor reducing component of the present invention with log P≧ can deposit through the wash.
This method is used to identify the presence of ambercore in the headspace above fabrics using the analytical chromatography technique of Gas Chromatography Mass Spectrometry equipped with a Dynamic Headspace DHS/Thermal Desorption Unit TDU/Cooled Injection System CIS, using a non-polar or slightly-polar column. This procedure is suitable for the qualitative presence of ambercore above fabrics treated with liquid laundry formulations containing ambercore. Suitable instruments for conducting these GC-MS analyses includes equipment such as: Hewlett Packard/Agilent Gas Chromatograph model 7890 series GC (Hewlett Packard/Agilent Technologies Inc., Santa Clara, Calif., U.S.A.); Hewlett Packard/Agilent Model 5977N Mass Selective Detector (MSD) transmission quadrupole mass spectrometer (Hewlett Packard/Agilent Technologies Inc., Santa Clara, Calif., U.S.A.); Multipurpose AutoSampler MPS2 equipped with an Automated Dynamic Headspace DHS/Thermal Desorption Unit TDU/Cooled Injection System CIS. (GERSTEL Inc., Linthicum, Md., U.S.A); and 5%-Phenyl-methylpolysiloxane Column J&W DB-5 (30 m length×0.25 mm internal diameter×0.25 μm film thickness) (J&W Scientific/Agilent Technologies Inc., Santa Clara, Calif., U.S.A.).
One skilled in the art will understand that in order to detect ambercore in the headspace, the analytical steps may involve the use of external ambercore reference standards to verify retention times and mass spectrum of the four isomers of ambercore.
Fabrics are treated with laundry formulas containing ambercore.
A 2 g piece of fabric is placed in a 10 mL headspace vial with a screw cap (Gerstel part #093640-038-00) with a metal screw cap (Gerstel part #093640-040-00)
The 10 mL vial is analyzed by headspace GC/MS via an Automated Dynamic Headspace Analyzer DHS/Thermal Desorption Unit TDU/Cooled Injection System CIS
The DHS parameters are set as follows: incubation is 75 C. incubation for 15 minutes; trapping phase settings are 200 ml collection @ 20 ml/min, Incubation 75 C., Transfer Temp 150 C., and Trap Temperature 25 C. The TDU parameters are set as follows TDU parameters: Initial Temperature 35 C., purge for 5 minutes @ 50 ml/min, heat to 280 C. @ 720 C./min, hold 5.0 min, solvent venting with vent time to 5.0 min. CIS parameters are set to cyro focused @−70, heat to 280 C. @ 12 C./sec, hold 4.0 min. The GC/MS parameters are set to: column J&W DB-5 MS 30 m×250 um×0.25 um (direct to MS no FID), PTV solvent vent, 1.6 ml/min, initial temperature 40 C., rate 16 C./min, and hold 280 C. for 3 min. Also note the following conditions for the analysis
Column: J&W DB-5, 30 m length×0.25 mm internal diameter×0.25 μm film thickness
Pneumatics: He, constant flow, 1.5 mL/min
Oven: 50 C. (0 min), 12 C./min, 280 C. (2 min)
MSD: Full Scan mode with a minimum range of 40 to 300 m/z (a wider range may be used). It is important that the final temperature of the system is selected such that it is sufficient to elute all of the perfume materials present in the test sample ethanol filtrate.
The results from the analysing a reference standard of ambercore is used to verify the presence of ambercore in the headspace above fabric. This is required to detected and correctly identify, by comparing the data. When a fabric is treated with a detergent containing 0.3% Amber Core, Amber Core is analytically detectable in the head space over the fabric demonstrating that this C log P≧3 deposits even through the wash without requiring the aid of a delivery technology.
