Description

[0001] COMPOSITIONS TO LIMIT OR ELIMINATE THE PERCEPTION OF SWEAT MALODOR

[0002] Field of the Disclosure

[0003] The present disclosure relates to volatile compositions to limit, decrease or eliminate the perception of sweat malodor, and uses thereof. The present disclosure also relates to consumer products, such as deodorants and / or antiperspirants, containing the said compositions.

[0004] Background of the Disclosure

[0005] Malodorous smells exist in many environments and are experienced in our daily life. Malodors are frequently complex mixtures of more than one malodorant compound which may typically include various amines, thiols, sulfides, short chain aliphatic and olefinic acids, e.g. fatty acids, and derivatives thereof. For example, body related malodors include, among others, those of short chain fatty acids, such as 3-hydroxy-3-methylhexanoic acid, 3-methyl-2- hexenoic acid, or 3-methyl-3-sulfanyl-hexan-1-ol (transpirol), which are typically found in axilla malodors.

[0006] Many sweat malodor control products on the market either overwhelm the customer with fragrance or lose effectiveness beyond 6 hours. Malodors are not pleasant for humans and therefore there is a constant need for malodor counteracting (MOC) compositions and / or ingredients for decreasing or suppressing the perception of malodors, particularly compositions and / or ingredients that provide long-lasting sweat malodor protection beyond 6 hours.

[0007] The present disclosure provides compositions and methods of use thereof to counteract sweat malodor by limiting, decreasing, or eliminating the perception of said malodor. The use of the compositions described herein in consumer products is also an object of the present disclosure.

[0223] The sweat malodor inhibiting composition may further comprise a perfuming coingredient. As used herein, a perfuming co-ingredient refers to ingredients that impart a hedonic effect, i.e., used for the primary purpose of conferring or modulating an odor. In other words, such a co-ingredient, to be considered as being a perfuming one, must be recognized by a person skilled in the art as being able to impart or modify in a positive or pleasant way the odor of a composition, and not just as having an odor. Perfuming co-ingredients may impart an additional benefit beyond that of modifying or imparting an odor, such as long-lasting, blooming, malodour counteraction, antimicrobial effect, antiviral effect, microbial stability, or pest control.

[0224] The nature and type of the perfuming co-ingredients do not warrant a more detailed description here, which in any case would not be exhaustive, the skilled person being able to select them on the basis of his general knowledge and according to the intended use or application and the desired organoleptic effect. In general terms, these perfuming co- ingredients belong to chemical classes as varied as alcohols, lactones, aldehydes, ketones, esters, ethers, acetates, nitriles, terpenoids, nitrogenous or sulphurous heterocyclic compounds, and essential oils. Perfuming co-ingredients can be of natural or synthetic origin. Suitable perfumery co-ingredients are in any case listed in reference texts such as the book by S. Arctander, Perfume and Flavor Chemicals, 1969, Montclair, New Jersey, USA, or its more recent versions, or in other works of a similar nature, as well as in the abundant patent literature in the field of perfumery. It is also understood that said co-ingredients may also be compounds known to release, in a controlled manner, various types of perfuming compounds, known as properfume or profragrance.

[0225] The sweat malodor inhibiting composition may optionally comprise a fragrance modulator.

[0226] Fragrance modulators, also known as fixatives, are agents having the capacity to affect the manner in which the odor, and in particular the evaporation rate and intensity, of the compositions incorporating said modulator can be perceived by an observer or user thereof, over time, as compared to the same perception in the absence of the modulator. In particular, the modulator allows prolonging the time during which their fragrance is perceived.

[0227] Examples of fragrance modulators suitable for use according to the present disclosure include, but are not limited to, caprylyl alcohol, octanol, butyloctanol, isotridecyl alcohol, hexyldecanol, isostearyl alcohol, octyldecanol, octyldodecanol, decyltetradecanol, tetradecyloctadecanol, PPG-20 methyl glucose ether, methyl glucoside polyol; ethyl glucoside polyol; propyl glucoside polyol; isocetyl alcohol; PPG-3 myristyl ether; neopentyl glycol diethylhexanoate; sucrose laurate; sucrose dilaurate, sucrose myristate, sucrose palmitate, sucrose stearate, sucrose distearate, sucrose tristearate, hyaluronic acid disaccharide sodium salt, sodium hyaluronate, propylene glycol propyl ether; dicetyl ether; polyglycerin-4 ethers; isoceteth-5; isoceteth-7, isoceteth-10; isoceteth-12; isoceteth-15; isoceteth-20; isoceteth-25; isoceteth-30; disodium lauroamphodipropionate; hexaethylene glycol monododecyl ether; and their mixtures; neopentyl glycol di isononanoate; cetearyl ethyl hexanoate; panthenol ethyl ether, DL-panthenol, N-hexadecyl n-nonanoate, noctadecyl n-nonanoate, a profragrance, cyclodextrin, an encapsulation, and any combination thereof.

[0228] The sweat malodor inhibiting compositions described herein may comprise a solid carrier. The sweat malodor inhibiting composition or elements of the composition can be chemically or physically bound. In general, such solid carriers are employed either to stabilize the composition, or to control the rate of evaporation of the compositions or of some ingredients. Solid carriers are of current use in the art and a person skilled in the art knows how to reach the desired effect. Suitable solid carriers include, but are not limited to, absorbing gums or polymers or inorganic materials, such as porous polymers, cyclodextrines, dextrines, maltodextrines wood-based materials, organic or inorganic gels, clays, gypsum talc or zeolites. Other suitable solid carriers include encapsulating materials. Examples of such materials may comprise wall-forming and plasticizing materials, such as glucose syrups, natural or modified starches, hydrocolloids, cellulose derivatives, polyvinyl acetates, polyvinylalcohols, proteins or pectins, plant gums such as acacia gum (Gum Arabic), urea, sodium chloride, sodium sulphate, zeolite, sodium carbonate, sodium bicarbonate, clay, talc, calcium carbonate, magnesium sulfate, gypsum, calcium sulfate, magnesium oxide, zinc oxide, titanium dioxide, calcium chloride, potassium chloride, magnesium chloride, zinc chloride, carbohydrates, saccharides such as sucrose, mono-, di-, and polysaccharides and derivatives such as chitosan, starch, cellulose, carboxymethyl methylcellulose, methylcellulose, hydroxyethyl cellulose, ethyl cellulose, propyl cellulose, polyols / sugar alcohols such as sorbitol, maltitol, xylitol, erythritol, and isomalt, polyethylene glycol (PEG), polyvinyl pyrrolidin (PVP), polyvinyl alcohol, acrylamides, acrylates, polyacrylic acid and related, maleic anhydride copolymers, amine- functional polymers, vinyl ethers, styrenes, polystyrenesulfonates, vinyl acids, ethylene glycolpropylene glycol block copolymers, vegetable gums, gum acacia, pectins, xanthanes, alginates, carragenans, citric acid or any water soluble solid acid, fatty alcohols or fatty acids and mixtures thereof.

[0229] Other suitable encapsulating materials are described in reference texts known to those of skill in the art, such as H. Scherz, Hydrokolloide: Stabilisatoren, Dickungs- und Geliermittel in Lebensmitteln, Band 2 der Schriftenreihe Lebensmittelchemie, Lebensmittelqualitat, Behr's Verlag GmbH & Co., Hamburg, 1996. The encapsulation is a well-known process to a person skilled in the art, and may be performed, for instance, by using techniques such as spraydrying, agglomeration or yet extrusion; or consists of a coating encapsulation, including coacervation and complex coacervation techniques.

[0230] Other exemplary solid carriers include core-shell capsules with resins of aminoplast, polyamide, polyester, polyurea or polyurethane type, and mixtures threof, made using techniques well-known to those of ordinary skill in the art, such as phase separation induced by polymerization, interfacial polymerization, coacervation, or a combination thereof, optionally in the presence of a polymeric stabilizer or of a cationic copolymer.

[0231] Resins may be produced by the polycondensation of an aldehyde (e.g., formaldehyde, 2,2-dimethoxyethanal, glyoxal, glyoxylic acid or glycolaldehyde, and mixtures thereof) with an amine such as urea, benzoguanamine, glycoluryl, melamine, methylol melamine, methylated methylol melamine, guanazole and the like, as well as mixtures thereof. Alternatively, one may use preformed resins like alkylolated polyamines such as those commercially available under the trademark URAC (origin: Cytec Technology Corp.), CYMEL (origin: Cytec Technology Corp.), URECOLL or LURACOLL (origin: BASF). Other suitable resins are the those produced by the polycondensation of a polyol, like glycerol, and a polyisocyanate, for example, a trimer of hexamethylene diisocyanate, a trimer of isophorone diisocyanate or xylylene diisocyanate or a Biuret of hexamethylene diisocyanate or a trimer of xylylene diisocyanate with trimethylolpropane (marketed as Takenate® by Mitsui Chemicals), among which a trimer of xylylene diisocyanate with trimethylolpropane and a Biuret of hexamethylene diisocyanate are of mention.

Dusselier, ACS Sustainable Chemistry & Engineering, 2019, vol. 7, pages 8041-8054. These publications are incorporated herein by reference.

[0233] The sweat malodor inhibiting compositions described herein may optionally comprise at least one perfumery adjuvant.

[0234] The at least one perfumery adjuvant is an ingredient capable of imparting an additional added benefit such as a color, a particular light resistance, chemical stability, etc. A detailed description of the nature and type of adjuvant commonly used in perfuming compositions cannot be exhaustive, but it has to be mentioned that said ingredients are well known to a person skilled in the art.

[0235] Exemplary perfumery adjuvants include, but are not limited to, viscosity agents (e.g., surfactants, thickeners, gelling and / or rheology modifiers), stabilizing agents (e.g., preservatives, antioxidant, heat / light and or buffers or chelating agents, such as BHT), coloring agents (e.g., dyes and / or pigments), preservatives (e.g. antibacterial or antimicrobial or antifungal or anti irritant agents), abrasives, skin cooling agents, insect repellants, ointments, vitamins and mixtures thereof.
