Description

[Technical Field]

[0001] The present invention relates to hair care compositions comprising a malodor-reducing composition, and methods of making and using such hair care compositions. [Background technology]

[0002] Unscented or lightly scented products are desired by consumers because they may be perceived as more natural and less obtrusive than stronger scented products. Manufacturers of unscented or lightly scented products that control malodors rely on malodor-reducing ingredients or other techniques (e.g., filters) to reduce the malodor. However, malodors such as amine-based malodors (e.g., fish and urine), thiol- and sulfide-based malodors (e.g., garlic and onion), C2-C3 12 Carboxylic acid malodors (e.g., body and pet odors), indole malodors (e.g., feces and breath), short-chain aliphatic aldehyde malodors (e.g., grease), and geosmin malodors (e.g., mold / mildew) are difficult to effectively control, and the time it takes for a product to significantly reduce the malodor can lead to consumer skepticism about the product's effectiveness against the malodor. Manufacturers often incorporate pleasant-smelling fragrances to mask these troublesome malodors.

[0003] Unfortunately, malodor control technologies typically mask malodors with stronger fragrances, thereby interfering with the fragrance of the perfumed or unscented areas treated with the malodor control technology. Thus, the limited nature of current malodor control technologies is extremely restrictive. Therefore, there is a need for broader malodor control technologies to enable the perfume industry to provide desired levels of properties in more situations / applications. Surprisingly, applicants have recognized that in order to achieve the desired goal, malodor control technologies must not only block malodor access to receptor cells, but also leave such receptor cells open to other molecules, such as fragrance molecules. Thus, hair care compositions containing the malodor control technology disclosed herein enable malodor control without leaving behind undesirable fragrances, and when fragrances are used to scent such compositions, such fragrances are not unduly altered by the malodor control technology.

[0004] Sulfur-containing antifungal hair and scalp care compositions offer some of the most effective protection from and relief from dandruff conditions. Traditionally, sulfur and other sulfur-based preparations have resulted in products with a strong medicinal or pungent odor during use and throughout the day due to the sulfur compounds remaining on the hair and scalp and their interaction with the hair and skin. These highly undesirable cosmetic properties can lead consumers to avoid sulfur and other sulfur-based preparations, making product usage difficult to follow, and often resulting in consumers not finding complete relief from their dandruff condition. Summary of the Invention [Means for solving the problem]

[0005] The present invention is directed to a hair care composition comprising, based on the total weight of the composition: a) from about 0.1% to about 2% in total of a fragrance comprising one or more malodor-reducing materials, the fragrance comprising from about 0.0001% to about 2% by weight of the one or more malodor-reducing substances; b) from about 0.01% to about 10% of a scalp active selected from the group consisting of sulfur and mixtures thereof; and c) from about 0.1% to about 40% of a surfactant. DETAILED DESCRIPTION OF THE INVENTION

[0006] definition "Hair care compositions" as defined herein can include shampoos, conditioners and leave-on treatments.

[0007] By "rinse-off" it is meant that the intended use of the product includes application to the hair followed by rinsing and / or wiping of the product from the skin and / or hair within a few seconds to a few minutes of this application step.

[0008] "STnS" refers to sodium trideceth(n) sulfate, where n can define the average number of moles of ethoxylate per molecule.

[0009] As used herein, "MORV" is the calculated malodor reduction value for a substance of interest. The MORV of a substance indicates the ability of such material to reduce the detection or even eliminate the perception of one or more malodors. For purposes of this application, the MORV of a substance is calculated according to the method found in the Test Methods section of this application.

[0010] As used herein, "malodor" means a compound that is generally unpleasant or objectionable to most people, such as the complex odor associated with bowel movements.

[0011] As used herein, the term "odor-blocking" refers to the ability of a compound to dull the perception of malodors.

[0012] As used herein, the term "fragrance" does not include malodor-reducing substances. Thus, the fragrance portion of a composition does not include malodor-reducing substances (e.g., malodor-reducing substances as described herein) that are found in the composition when the perfume's composition is determined. Simply put, if the malodor reduction value "MORV" of a substance is within the MORV range referred to in this claim, then such substance is a malodor-reducing substance for purposes of this claim.

[0013] As used herein, PRM is an abbreviation for perfume raw material.

[0014] As used herein, the terms "a" and "an" mean "at least one."

[0015] As used herein, the terms "include," "includes," and "including" are meant to be non-limiting.

[0016] Unless otherwise noted, all component or composition levels refer to the active portion of that component or composition and exclude impurities, e.g., residual solvents or by-products, that may be present in commercial sources of such component or composition.

[0017] 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.

[0018] 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 is intended to 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.

[0019] Hair care composition The rinse-off hair care composition can be provided in a variety of forms, for example, the hair care composition can be in liquid form, such as a shampoo or a conditioning shampoo.

[0020] Hair care compositions can include fragrance materials. Many consumers prefer hair care compositions that consistently provide a desired scent or odor that can be perceived each time the product is used. Fragrance materials can provide these hair care compositions with a desired scent or odor. These fragrance (i.e., fragrance) materials can include perfumes, perfume raw materials, and fragrance delivery systems. The present invention may have a total of about 0.1% to about 2% of a perfume containing one or more malodor-reducing substances, a total of about 0.5% to about 1.5% of a perfume containing one or more malodor-reducing substances, a total of about 0.8% to about 1.2% of a perfume containing one or more malodor-reducing substances, or a total of about 0.85% to about 1.0% of a perfume containing one or more malodor-reducing substances.

[0021] Odor-reducing substances A non-limiting set of suitable malodor reducing substances is provided in the table below: In the present invention, the malodor reducing substance may be selected from one or more perfume raw materials.

[0038] sulfur The hair care compositions of the present invention may contain sulfur. Sulfur suitable for use herein can be elemental sulfur in any form. At room temperature, sulfur exists primarily as orthorhombic crystals. The two most common methods for obtaining elemental sulfur are by precipitation from hydrogen sulfide derived from contaminants in sour gas using the Claus process, or by mining underground deposits using superheated water, known as the flash process. Other forms of sulfur, such as monoclinic crystalline sulfur, oligomeric sulfur, or polymeric sulfur, are common primary forms of elemental sulfur at certain elevated temperatures. At room temperature, these forms convert or revert to orthorhombic sulfur. Elemental sulfur may be physically mixed with protective colloids such as gum arabic, clay, wax, oil, activated carbon, zeolite, or silica, or with dispersing agents such as surfactants, or may have undergone processing steps to modify its particle size and other physical properties. Sulfur is commercially available in a variety of forms, including pellets, cakes, prills, colloidal, micronized, sublimated, precipitated, and commercially available powders.

[0039] The sulfur may have a particle size distribution with 90% of the particles (D90) between about 30 micrometers (μm) and about 250 micrometers (μm). The sulfur may have a particle size distribution with a D90 between about 30 micrometers (μm) and about 200 micrometers (μm). The sulfur may have a particle size distribution with a D90 between about 30 micrometers (μm) and about 150 micrometers (μm). The sulfur may have a particle size distribution with a D90 between about 30 micrometers (μm) and about 100 micrometers (μm).

[0040] The sulfur may have a particle size distribution where 50% of the particles (D50) are between about 5 micrometers (μm) and about 150 micrometers (μm). The sulfur may have a particle size distribution where D50 is between about 10 micrometers (μm) and about 100 micrometers (μm). The sulfur may have a particle size distribution where D50 is between about 15 micrometers (μm) and about 75 micrometers (μm). The sulfur may have a particle size distribution where D50 is between about 20 micrometers (μm) and about 50 micrometers (μm).

[0041] The sulfur may have a particle size distribution where 10% of the particles (D10) are from about 1 micrometer (μm) to about 25 micrometers (μm). The sulfur may have a particle size distribution where D10 is from about 5 micrometers (μm) to about 25 micrometers (μm). The sulfur may have a particle size distribution where D10 is from about 10 micrometers (μm) to about 25 micrometers (μm). The sulfur may have a particle size distribution where D10 is from about 18 micrometers (μm) to about 25 micrometers (μm).

[0042] Sulfur may be present in a D(90) / D(10) ratio of about 3 to about 100. Sulfur may be present in a D(90) / D(10) ratio of about 3 to about 50. Sulfur may be present in a D(90) / D(10) ratio of about 3 to about 10. Sulfur may be present in a D(90) / D(10) ratio of about 3 to about 4.

[0043] Sulfur may be present in an amount between about 0.01% and 10%, between about 0.1% and about 9%, between about 0.25% and 8%, between about 0.5% and 6%.

[0044] Auxiliary materials Although not required for purposes of the present invention, the non-limiting list of adjuvants exemplified below are suitable for use in the present compositions and may be desirable to incorporate in certain embodiments of the present invention, for example, to aid or enhance performance.

[0045] A variety of optional ingredients can also be added to the hair care composition, including, but not limited to, structuring agents, humectants, fatty acids, inorganic salts, and other antimicrobial agents or active agents.

[0046] The hair care composition can also include hydrophilic structuring agents, such as carbohydrate structuring agents and gums. Some suitable carbohydrate structuring agents include raw starches (corn, rice, potato, wheat, etc.) and pregelatinized starches. Some suitable gums include carrageenan and xanthan gum. The hair care composition can include from about 0.1% to about 30%, from about 2% to about 25%, or from about 4% to about 20% of the carbohydrate structuring agent, by weight of the hair care composition.

[0047] The hair care composition can optionally contain one or more humectants. Examples of such humectants include polyhydric alcohols. Furthermore, humectants such as glycerin can be included in the hair care composition as a result of production or as an additional component. For example, glycerin can be a by-product of the saponification of the hair care composition. The inclusion of an additional humectant can provide many benefits, such as improving the hardness of the hair care composition, reducing the water activity of the hair care composition, and reducing the rate of weight loss of the hair care composition over time due to water evaporation.

[0048] The hair care composition can include an inorganic salt. The inorganic salt can help maintain a specific water content or amount of the hair care composition and improve the hardness of the hair care composition. The inorganic salt can also help bind water in the hair care composition to prevent water loss by evaporation or other means. The hair care composition can optionally include from about 0.01% to about 15%, from about 1% to about 12%, or from about 2.5% to about 10.5% by weight of the hair care composition of the inorganic salt. Examples of suitable inorganic salts include magnesium nitrate, trimagnesium phosphate, calcium chloride, sodium carbonate, sodium aluminum sulfate, disodium phosphate, sodium polymetaphosphate, sodium magnesium succinate, sodium tripolyphosphate, aluminum sulfate, aluminum chloride, aluminum chlorohydrate, aluminum-zirconium trichlorohydrate, aluminum-zirconium trichlorohydrate glycine complex, zinc sulfate, ammonium chloride, ammonium phosphate, calcium acetate, calcium nitrate, calcium phosphate, calcium sulfate, ferric sulfate, magnesium chloride, magnesium sulfate, and tetrasodium pyrophosphate.

[0049] The hair care composition can include one or more additional antimicrobial agents, which can further enhance the antimicrobial efficacy of the hair care composition. The hair care composition can include, for example, from about 0.001% to about 2%, from about 0.01% to about 1.5%, or from about 0.1% to about 1% of the additional antimicrobial agent(s) by weight of the hair care composition. Examples of suitable antimicrobial agents include carbanilide, triclocarban (also known as trichlorocarbanilide), triclosan, halogenated diphenyl ether available from Ciba-Geigy as DP-300, hexachlorophene, 3,4,5-tribromosalicylanilide, and 2-pyridinethiol-1-oxide, salicylic acid, and salts of other organic acids. Other suitable antimicrobial agents are described in U.S. Patent No. 6,488,943.

[0050] scalp active substances In the present invention, the hair care composition may include a scalp activator, and the scalp activator may be an anti-dandruff active ingredient. The anti-dandruff active ingredient may be selected from the group consisting of pyridinethione salts, zinc carbonate, azoles such as ketoconazole, econazole, and elubiol, selenium sulfide, particulate sulfur, colloidal sulfur, keratolytic agents such as salicylic acid, and mixtures thereof. The anti-dandruff active ingredient may be anti-dandruff microparticles. The anti-dandruff microparticles are pyridinethione salts. Such anti-dandruff microparticles must be physically and chemically compatible with the components of the composition and must not unduly impair the stability, aesthetics, or performance of the product.

[0051] In the present invention, sulfur, or selenium sulfide, may be present in amounts of about 0.01% to 10%, about 0.1% to about 9%, about 0.25% to 8%, and about 0.5% to 6%.

[0052] Pyridinethione particles are a preferred particulate anti-dandruff active ingredient for use in the compositions of the present invention. In the present invention, the anti-dandruff active ingredient may be a 1-hydroxy-2-pyridinethione salt, in particulate form. In the present invention, the concentration of pyridinethione anti-dandruff particulates may range from about 0.01% to about 5%, or from about 0.1% to about 3%, or from about 0.1% to about 2% by weight of the composition. In the present invention, pyridinethione salts can be formed from heavy metals such as zinc, tin, cadmium, magnesium, aluminum, and zirconium, typically zinc, primarily zinc salts of 1-hydroxy-2-pyridinethione ("zinc pyridinethione" or "zinc pyridinethione, ZPT," also known as zinc pyrithione), typically 1-hydroxy-2-pyridinethione salts in platelet particle form. In the present invention, the 1-hydroxy-2-pyridinethione salts, which may be in the form of platelet particles, may have an average particle size of up to about 20 microns, or up to about 5 microns, or up to about 2.5 microns. Salts formed from other cations (e.g., sodium) may also be suitable. Pyridinethione anti-dandruff active ingredients are described, for example, in U.S. Patent Nos. 2,809,971, 3,236,733, 3,753,196, 3,761,418, 4,345,080, 4,323,683, 4,379,753, and 4,470,982.

[0053] In accordance with the present invention, the composition further comprises, in addition to the anti-dandruff active ingredient selected from polyvalent metal salts of pyrithione, one or more antifungal and / or antibacterial active ingredients. In the present invention, the antibacterial active ingredient may be coal tar, sulfur, charcoal, Whitfield's ointment, Castellani liniment, aluminum chloride, gentian violet, octopirox (piroctone olamine), ciclopirox olamine, undecylenic acid and its metal salts, potassium permanganate, selenium sulfide, sodium thiosulfate, propylene glycol, bitter orange oil, urea preparation, azoxystrobin, griseofulvin, 8-hydroxyquinoline citric acid, thiobendazole, thiocarbamate, haloprogin, polyene, hydroxypyridone, morpholine, benzylamine, allylamine (terbinafine, etc.), tea tree oil, clove leaf oil, coriander, palmarosa, berberine, thyme red, cinnamon bark oil, cinnamic aldehyde, citronellic acid, hinoki tol, ichthyol pale, Sensiva SC-50, Elestab HP-100, azelaic acid, lyticase, iodopropynyl butylcarbamate (IPBC), isothiazarinones such as octylisothiazarinone, azoles, and mixtures thereof. In the present invention, the antibacterial agent may be selected from the group consisting of itraconazole, ketoconazole, selenium sulfide, coal tar, and mixtures thereof.

[0054] In the present invention, the azole antibacterial agent may be an imidazole selected from the group consisting of benzimidazole, benzothiazole, bifonazole, butaconazole nitrate, climbazole, clotrimazole, cloconazole, eberconazole, econazole, elubiol, fenticonazole, fluconazole, flutimazole, isoconazole, ketoconazole, lanoconazole, metronidazole, miconazole, neticonazole, omoconazole, oxiconazole nitrate, sertaconazole, sulconazole nitrate, tioconazole, thiazole, and mixtures thereof, or the azole antibacterial agent may be a triazole selected from the group consisting of terconazole, itraconazole, and mixtures thereof. When present in the composition, the azole antibacterial active ingredient is present in an amount of about 0.01% to about 5%, or about 0.1% to about 3%, or about 0.3% to about 2% by weight of the total weight of the composition. In the present invention, the azole antibacterial active ingredient may be ketoconazole.In the present invention, the only antibacterial active ingredient may be ketoconazole.

[0055] The present invention may also include a combination of antibacterial active ingredients, which may be selected from the group consisting of octopirox and zinc pyrithione, pine tar and sulfur, salicylic acid and zinc pyrithione, salicylic acid and elubiol, zinc pyrithione and elubiol, zinc pyrithione and climbazole, octopirox and climbazole, salicylic acid and octopirox, and mixtures thereof.

[0056] In the present invention, the composition may comprise an effective amount of zinc-containing layered material, such as from about 0.001% to about 10%, or from about 0.01% to about 7%, or from about 0.1% to about 5% of the zinc-containing layered material by total weight of the composition.

[0057] Zinc-containing layered materials may be those in which crystal growth occurs primarily in two dimensions. It is customary to describe the layered structure not only as having all atoms incorporated into well-defined layers, but also as having ions or molecules between the layers, called gallery ions (A.F. Wells, "Structural Inorganic Chemistry," Clarendon Press, 1975). Zinc-containing layered materials (ZLMs) may incorporate zinc into the layers and / or as a component of the gallery ions. The following classifications of ZLMs represent relatively general examples of general categories and are not intended to be limiting with respect to the broader range of materials that fit this definition.

[0058] Many ZLMs occur naturally as minerals. In the present invention, the ZLM may be selected from the group consisting of hydrozincate (zinc carbonate hydroxide), basic zinc carbonate, hydrozincate (zinc copper carbonate hydroxide), zinc malachite (zinc copper carbonate hydroxide), and mixtures thereof. Related minerals containing zinc may also be included in the composition. Natural ZLMs may also exist in which anionic layer species, such as clay minerals (e.g., phyllosilicates), contain ion-exchanged zinc gallery ions. All of these natural materials may be synthetically obtained or formed in situ in the composition or during the manufacturing process.

[0059] Another general class of ZLMs, which are often, but not always, synthetic, are layered double hydroxides. In the present invention, ZLMs are those having the formula [M 2+ 1-x M 3+ x (OH)2] x+ A m- x / m nH2O (wherein divalent ions (M 2+) may be a layered double hydroxide conforming to (Crepaldi, EL, Pava, PC, Tronto, J, Valim, JB J. Colloid Interfac. Sci. 2002, 248, 429-42), in which some or all of the ions are zinc ions.

[0060] Another class of ZLMs, called hydroxy double salts, can also be prepared (Morioka, H., Tagaya, H., Karasu, M., Kadokawa, J., Chiba, K. Inorg. Chem. 1999, 38, 4211-6). In the present invention, ZLMs are those having the formula [M 2+ 1-x M 2+ 1+x (OH) 3(1-y) ] + A n- (1=3y) / n nH2O (wherein two metal ions (M 2+ ) may be the same or different) and may be a hydroxy double salt corresponding to ). When the metal ion is the same and is represented by zinc, the formula is simplified to [Zn 1+x (OH)2] 2x+ 2x A - ·nH2O. This latter formula represents materials such as zinc hydroxychloride and zinc hydroxynitrate (where x=0.4). In the present invention, ZLM can be zinc hydroxychloride and / or zinc hydroxynitrate. This also relates to zinc hydroxylates in which a divalent anion replaces a monovalent anion. These materials can also be formed in situ in the composition or during the manufacturing process.

[0061] In the present invention, the composition may contain basic zinc carbonate. Commercial sources of basic zinc carbonate include basic zinc carbonate (Cater Chemicals, Bensenville, IL, USA), zinc carbonate (Shepherd Chemicals, Norwood, OH, USA), zinc carbonate (CPS Union Corp., New York, NY, USA), zinc carbonate (Elementis Pigments, Durham, UK), and zinc carbonate AC (Bruggemann Chemical, Newtown Square, PA, USA). Basic zinc carbonate, sometimes commercially referred to as "zinc carbonate," "zinc carbonate base," or "zinc hydroxycarbonate," is a synthetic product made from materials similar to natural zinc oxide. While the ideal stoichiometry is represented by Zn5(OH)6(CO3)2, the actual stoichiometric ratio may vary slightly, and other impurities may be incorporated into the crystal lattice.

[0062] The present invention can contain a zinc-containing layered material and pyrithione or a polyvalent metal salt of pyrithione, and the ratio of the zinc-containing layered material to the pyrithione or the polyvalent metal salt of pyrithione is about 5:100 to about 10:1, or about 2:10 to about 5:1, or about 1:2 to about 3:1.

[0063] Hair care composition Exemplary hair care rinse-off compositions can include an aqueous carrier, which can be present in an amount of from about 5% to about 95%, from about 60% to about 85%. The aqueous carrier can include water or a miscible mixture of water and an organic solvent. Non-aqueous carrier materials can also be used.

[0064] In the present invention, the surfactant may be present in the range of about 0.1% to about 40%, about 0.5% to about 30%, or about 1% to about 25%.

[0065] Such rinse-off hair care compositions may comprise one or more detersive surfactants. The detersive surfactant component may be included to provide cleaning performance to the product. The detersive surfactant component may comprise an anionic detersive surfactant, a zwitterionic or an amphoteric detersive surfactant, or a combination thereof. A representative, non-limiting list of anionic surfactants for use in the compositions includes ammonium lauryl sulfate, ammonium laureth sulfate, triethylamine lauryl sulfate, triethylamine laureth sulfate, triethanolamine lauryl sulfate, triethanolamine laureth sulfate, monoethanolamine lauryl sulfate, monoethanolamine laureth sulfate, diethanolamine lauryl sulfate, diethanolamine laureth sulfate, lauryl monoglyceride sodium sulfate, sodium lauryl sulfate, sodium laureth sulfate, potassium lauryl sulfate, potassium laureth sulfate, sodium lauryl sarcosinate, sodium lauroyl sarcosinate, lauryl sarcosine, cocoyl sarcosine, ammonium cocoyl sulfate, ammonium lauroyl sulfate, sodium cocoyl sulfate, sodium lauroyl sulfate, potassium cocoyl sulfate, potassium lauryl sulfate, triethanolamine lauryl sulfate, triethanolamine lauryl sulfate, monoethanolamine cocoyl sulfate, monoethanolamine lauryl sulfate, sodium tridecylbenzenesulfonate, sodium dodecylbenzenesulfonate, sodium cocoyl isethionate, and combinations thereof. In one example, the anionic surfactant may be sodium lauryl sulfate or sodium laureth sulfate. The concentration of the anionic surfactant component in the product may be sufficient to provide the desired cleaning and / or lathering performance, generally ranging from about 2% to about 40%.

[0066] Amphoteric cleansing surfactants suitable for use in rinse-off hair care compositions are well known in the art and include surfactants generally described as derivatives of aliphatic secondary and tertiary amines, where the aliphatic radical can be linear or branched, the aliphatic substituent can contain from about 8 to about 18 carbon atoms, and one carbon atom can contain an anionic water-solubilizing group, such as carboxy, sulfonate, sulfate, phosphate, or phosphonate.Examples of compounds that fit this definition include sodium 3-dodecylaminopropionate, sodium 3-dodecylaminopropanesulfonate, N-alkyltaurines such as those prepared by reacting dodecylamine with sodium isethionate according to the teachings of U.S. Pat. No. 2,658,072, N-higher alkylaspartic acids such as those produced according to the teachings of U.S. Pat. No. 2,438,091, and the products described in U.S. Pat. No. 2,528,378. Other examples of amphoteric surfactants may include sodium lauroamphoacetate, sodium cocoamphoacetate, disodium lauroamphoacetate, disodium cocoamphoacetate, and mixtures thereof. Amphoacetates and diamphoacetates may also be used.

[0067] Zwitterionic detersive surfactants suitable for use in rinse-off hair care compositions are well known in the art and include surfactants broadly described as derivatives of aliphatic quaternary ammonium, phosphonium, and sulfonium compounds, where the aliphatic radical can be straight or branched, the aliphatic substituent can contain from about 8 to about 18 carbon atoms, and one carbon atom can contain an anionic group, such as carboxy, sulfonate, sulfate, phosphate, or phosphonate. Other zwitterionic surfactants can include betaines, including cocoamidopropyl betaine.

[0068] In the present invention, the hair care composition may contain a cationic surfactant.

[0069] Liquid rinse-off hair care compositions can include one or more phases. Such hair care compositions can include a cleansing phase and / or a benefit phase (i.e., a single-phase or multi-phase composition). Each of the cleansing phase or benefit phase can include various ingredients. The cleansing phase and benefit phase can be pre-mixed, separate, or a combination thereof. The cleansing phase and benefit phase can also be patterned (e.g., striped).

[0085] Test Method The malodor-reducing substances can be isolated from the mixture, including but not limited to, end products such as consumer products, and identified by analytical methods including GC-MS and / or NMR.

[0086] Test Method for Determining Saturated Vapor Pressure (VP) (VP@25C) Saturated vapor pressure (VP) values ​​are calculated for each perfume raw material (PRM) in the perfume mixture being tested. The VP of each PRM is calculated using the VP Computational Model, version 14.02 (Linux), available from Advanced Chemistry Development Inc. (ACD / Labs) (Toronto, Canada), which gives VP values ​​at 25°C expressed in units of torr. The ACD / Labs vapor pressure model is part of the ACD / Labs instrument.

[0087] Test method for determining the logarithm of the octanol / water partition coefficient (logP) The logarithm of the octanol / water partition coefficient (logP) was calculated for each PRM in the fragrance mixture being tested. The logP values ​​of individual PRMs were calculated using the Consensus logP Computational Model, version 14.02 (Linux), available from Advanced Chemistry Development Inc. (ACD / Lab) (Toronto, Canada), to obtain dimensionless logP values. The ACD / Labs Consensus logP Computational Model is part of the ACD / Labs model suite.

[0088] Test methods for the creation of molecular descriptors To perform the calculations involved in the computational value testing methods described herein, the initial information required includes the identity of each PRM in the perfume being tested, its weight % as a percentage of the perfume, and its mole % so that all PRMs in the perfume composition are included in the calculation. Additionally, for each of these PRMs, the molecular structure, values ​​of the various computationally derived molecular descriptors are also required, as determined according to the testing methods for generating molecular descriptors described herein.

[0089] For each PRM in a fragrance mixture or composition, its molecular structure is used to quantify various molecular descriptors. Molecular structures are determined from graphic molecular structure diagrams provided by the Chemical Abstract Service ("CAS"), a division of the American Chemical Society (Columbus, Ohio, USA). These molecular structures can be obtained by looking up the index name or CAS number of each PRM in the CAS Chemical Registry System database. For PRMs not yet listed in the CAS Chemical Registry System database at the time of testing, other databases or sources may be used to determine their structures. For PRMs that may have more than one isomer, the molecular structure of only one isomer selected to represent the PRM is used to perform the quantification of molecular descriptors. The choice of isomer is determined by the relative extent of the molecular structures of the isomers. Of all isomers of a given PRM, the isomer whose molecular structure is most predominant is the isomer selected to represent the PRM. The structures of other possible isomers of the PRM are excluded from this quantification. The molecular structure of the most relevant isomer is combined with the concentration of the PRM, which reflects the presence of all isomers of the PRM present.

[0090] Use a molecular editor or molecular drawing software program, such as ChemDraw (CambridgeSoft / PerkinElmer Inc., Waltham, Massachusetts, USA), to recreate a two-dimensional molecular structure representing each PRM. Molecular structures must be represented as neutral species (quaternary nitrogen atoms are allowed) without unlinked fragments (e.g., single structures without counterions). The winMolconn program, described below, can convert any deprotonated functional group to its neutral form by adding the appropriate number of hydrogen atoms, eliminating the need for counterions.

[0091] For each PRM, molecular drawing software is used to create a file describing the PRM's molecular structure. The file(s) describing the PRM's molecular structure are then sent to the computer software program winMolconn, version 1.0.1.3 (Hall Associates Consulting, Quincy, Massachusetts, USA, www.molconn.com) to derive various molecular descriptors for each PRM. The winMolconn software program thus describes the acceptable options for structure representation and file format. These options include either a MACCS SDF format file (i.e., structure data file) or a Simplified Molecular Input Line Entry Specification (i.e., SMILES string structure line representation), which is commonly used within simple text files and often has a ".smi" or ".txt" filename extension. SDF files represent each molecular structure in the form of a multiline record, while the syntax for SMILES structures is a single line of text with no whitespace. A structure name or identifier can be added to the SMILES string by including it on the same line following the SMILES string with a space between them, e.g., C1=CC=CC=C1 benzene.

[0092] The winMolconn software program is used to generate many molecular descriptors for each PRM, which are then output in tabular form. The specific molecular descriptors obtained by winMolconn are then used as input (i.e., as variable terms in mathematical equations) for various computer model test methods to calculate values ​​for each PRM, such as: saturated vapor pressure (VP); boiling point (BP); logarithm of the octanol / water partition coefficient (logP); odor detection threshold (ODT); malodor reduction value (MORV); and / or universal malodor reduction value (UNIVERSAL MORV). The molecular descriptor labels used in the model test method calculations are the same labels reported by the winMolconn program, and their descriptions and definitions can be found in a list in the winMolconn documentation. The following is a comprehensive description of how to run the winMolconn software program and generate the necessary molecular structure descriptors for each PRM in a composition.

[0093] Metrics for molecular structure descriptors using winMolconn: 1) Assembling the molecular structures of one or more perfume ingredients in the form of a MACCS structural data file, also called an SDF file, or as a SMILES file. 2) Using the winMolconn program, version 1.0.1.3, running on a suitable computer, and using the SDF file or SMILES file mentioned above as input, calculate all of the molecular descriptors available from this program. The output of a.winMolconn is in the form of an ASCII text file, typically space-delimited, containing, for each structure in the input file, a structure identifier in the first column and respective molecular descriptors in the remaining columns. 3) Using a spreadsheet software program or some other suitable technique, parse the text file into columns. The molecular descriptor labels are found in the first row of the resulting table. 4) Find and extract the descriptor sequences identified by the molecular descriptor labels and corresponding to the required inputs for each model. a. Note that the labels in winMolconn molecular descriptors are case sensitive.

[0094] MORV calculation 1.) Enter the molecular descriptor values ​​determined by the above method into the following equation: MORV=-0.0035+0.8028x(SHCsatu)+2.1673x(xvp7)-1.3507x(c1C1C3d)+0.61496x(c1C1O2)+0.00403x(idc)-0.23286x(nd2).

[0095] This formula relates to the effectiveness of a material in reducing the malodor 3-mercapto-3-methylhexan-1-ol (a thiol malodor), which in the present invention is used as a marker for hydrogen sulfide and other sulfur odorous compounds such as methanethiol.

[0096] 2.) For purposes of this application, the MORV of a material is taken to be the highest MORV value from the above formula.

[0097] The purpose of this experimental design is to determine whether the malodor-reducing composition is effective in reducing the perception of malodor from a sulfur-containing shampoo.

[0098] Perceptual Test Method: The hair switch was rinsed thoroughly with water (38°C) to thoroughly wet the switch (5-10 seconds). 0.1 g of test material per gram of hair was added and lathered for 20 seconds. At 20 seconds, water was added and lathering continued for 30 seconds. The hair switch was evaluated for sulfur malodor (SM-1). The hair switch was thoroughly rinsed. The hair switch was evaluated for sulfur malodor (SM-2). The hair switch was gently wiped dry with a towel. The hair switch was blow-dried on a high heat setting until completely dry to the touch. The hair switch was immediately evaluated for sulfur malodor (SM-3). The hair switch was allowed to cool for 3-5 minutes (until it felt cool to the touch). The hair switch was evaluated for sulfur malodor (SM-4). SM-1, SM-2, SM-3, and SM-4 were added together to obtain total sulfur malodor (TSM), or cumulative sulfur odor.

[0099] In the present invention, sulfur malodor can be rated or measured on a scale of 0 (no malodor) to 9 (severe malodor). A non-limiting example of malodor rating can be as follows: Malodor Rating Scale A 10-point scale with the following descriptions: 0 = none, no scent / malodor present, 1 = slight scent / malodor present (unsure), 2 = mild to moderate, detect something but can you recognize what it is?, 3 = moderate slight scent / malodor present, 4 = moderate to high moderate scent / malodor present, 5 = high, 6 = high to very high, 7 = very strong scent / malodor present, 8 = extremely high, 9 = very high, even very strong scent / malodor present.
