Description

Title of the invention: Methods for reducing frizz and improving smooth texture of hair SCOPE OF DISCLOSURE

[0001] The present disclosure relates to methods of reducing frizz and increasing smoothness of hair requiring reduced frizz or increased smoothness. Hair is treated with a rinse-out hair treatment composition and then treated with a heat treatment. Treatment with the compositions provides the hair with improved fiber alignment, frizz control, and smoothness. CONTEXT

[0002] Many consumers wish to use cosmetic and care compositions that enhance the appearance of the hair, for example, by changing the color, style and / or shape of the hair and / or by imparting various cosmetic properties to the hair, such as shine and conditioning. Hair can become dry or damaged for a variety of reasons, for example, exposure to the elements, poor nutrition, mechanical treatments (e.g., brushing the hair), styling treatments using chemicals, dyeing, heat, nutrition, etc. Even cleansing shampoos can strip the hair of its natural oils, causing dryness, which can lead to a dull appearance and split ends.

[0003] Chemical hair treatments include bleaching and coloring treatments to change the color of the hair. Chemical treatments also include processes to permanently change the shape and structure of the hair, for example, by perming, waving, relaxing, or straightening the hair. These chemical treatments often alter the appearance of the hair by changing its physical structure, which inevitably causes some degree of damage to the hair. Environmental factors, such as salt water, sunlight, and heat, are also known to damage hair. Damaged hair is characterized by unnatural changes in the protein structure of individual hair strands or shafts.

[0004] The popularity and use of oils for hair treatment has increased due to their effectiveness and simplicity. Commonly used oils include olive oil, mineral oil, avocado oil, apricot kernel oil, rice bran oil, and coconut oil. However, these treatments can make hair greasy. Furthermore, effects are usually not seen until several hours (e.g., 8 hours) of treatment, and multiple treatments are ha- necessarily necessary, which makes the treatment time-consuming and laborious.

[0005] Hair damage results in split ends, dryness, easily crunched hair, and hair that becomes "frizzy" and difficult to style. Because the visible part of the hair is dead, it cannot regenerate itself. Many over-the-counter and salon treatments are claimed to repair damaged hair. These include conditioners, hot oil treatments, hydrolyzed proteins, vitamin formulations, and extracts of exotic fruits, leaves, or roots. However, these treatments provide little improvement to the hair. Therefore, hair treatment technologies that can straighten, relax, or style hair without chemically damaging it are desired.

[0006] There is a need to improve the manageability of hair, for example, to improve hair alignment, to reduce unwanted volume (particularly a reduction in frizz), and to increase shine.

[0007] Furthermore, the formulation of environmentally friendly cosmetic products, which are designed and developed with environmental issues in mind, is becoming a major objective in an effort to address global challenges. It is therefore essential to provide more sustainable compositions, preparation processes and ingredients to address these environmental concerns. In this context, it is important to develop new cosmetic compositions with a better carbon footprint, in particular by promoting the use of renewable raw materials and / or materials with a good naturalness index and / or materials of natural origin and, more particularly, materials of plant origin while reducing the use of compounds of petrochemical origin. SUMMARY OF DISCLOSURE

[0008] The present disclosure relates to methods for improving the appearance, feel, and manageability of hair. In particular, the methods improve fiber alignment, reduce frizz, and impart a smooth texture to the hair. Treated hair is soft, shiny, conditioned, and has a healthy appearance. The methods utilize a hair treatment composition containing at least one acyclic carbonate ester having a plurality of C6-C18 fatty chains, which may undergo a reaction when subjected to heat treatment. For example, heat from a hot iron activates a crosslinking or other modification reaction with the amine groups of the hair fibers. Without wishing to make any particular theory, the inventors believe that the methods result in grafting a fatty alkyl chain to the surface and / or N,N'-disubstituted urea bonds with the keratinous fibers of the hair.In addition, the enhanced cosmetic properties imparted to the hair are long-lasting and maintained even after multiple wash cycles.

[0009] The methods of the present disclosure are generally used to reduce frizz or increase smoothness of hair by:

[0010] (i) applying a hair treatment composition to hair born requiring a reduction in frizz or an increase in softness; the composition comprising:

[0011] (a) about 5 to about 50% by weight of at least one acyclic carbonate ester having a plurality of C6-C18 fatty chains; and

[0012] (b) a liquid vehicle,

[0013] wherein all weight percentages are based on a total weight of the composition;

[0014] (ii) subjecting the hair to a heat treatment, wherein the heat treatment heats the hair to a temperature of at least 150°C.

[0015] In various embodiments, after applying the hair treatment composition, the hair is dried after rinsing the hair treatment composition, for example, using a hair dryer. Most hair dryers reach a maximum temperature of about 90°C to about 120°C. Therefore, once the hair is dried, it may be treated with a hot iron (preferably a flat iron) or other heat treatment at a temperature of about 150°C to about 280°C. A hot iron may be passed over the hair one or more times.

[0016] In various embodiments, the hair treatment composition includes one or more silicones. Silicones can protect hair from damage caused by heat styling tools such as hair dryers and hot irons. The slicked-back, glossy texture of silicones also helps impart softness and smoothness to the hair. In various embodiments, at least one of the one or more silicones is an amino-functionalized silicone. Non-limiting examples of amino-functionalized silicones include amodimethicone, bis-hydroxy / methoxy amodimethicones, bis-cetearyl amodimethicone, bis(C13-C15 alkoxy) PG amodimethicones, aminopropyl phenyl trimethicones, aminopropyl dimethicone, bis-amino PEG / PPG-41 / 3 aminoethyl PG-propyl dimethicone, or a combination thereof.

[0017] Film-forming polymers may also be incorporated into the hair treatment composition. The film-forming polymers may provide additional heat protection to the hair and simultaneously function to "preserve" the shape and style of the hair. In various embodiments, the hair treatment composition includes one or more film-forming polymers selected from anionic film-forming polymers, nonionic film-forming polymers, amphoteric film-forming polymers, or a combination thereof.

[0018] In various embodiments, the hair treatment composition includes a or more polysaccharides, for example, one or more polysaccharides selected from starches, gums and cellulose-based polymers, and a mixture thereof, preferably one or more polysaccharides are selected from xanthan gum, gellan gum, sclerotium gum, guar gum and its derivatives, cellulose and its derivatives, and a mixture thereof.

[0019] In various embodiments, the hair treatment composition includes one or more nonionic associative polymeric thickeners. A non-limiting but useful class of nonionic associative polymeric thickeners includes polyurethane thickeners, for example, polyurethane / polyether thickeners. Non-limiting examples of polyurethane / polyether thickeners include bis-decyltetradeceth-20 ether of PEG-240 / HDI copolymer, PEG-150 / stearyl alcohol / SMDI copolymer, PEG-150 / decyl alcohol / SMDI copolymer, steareth-100 / PEG-136 / HDI copolymer, or a mixture thereof.

[0020] In various embodiments, one or more emulsifiers may also be included. A non-limiting but useful class of emulsifiers are such non-ionic emulsifiers. The non-ionic surfactant or emulsifier may have an HLB (hydrophilic-lipophilic balance) ranging from 1 to 7.9 or greater than or equal to 8. Non-limiting examples include polyoxyalkylenated or polyglycerolated non-ionic surfactants.

[0021] Hair treated according to the methods disclosed herein exhibits improved fiber alignment, improved frizz control, and improved smooth texture. These desirable cosmetic attributes are long-lasting and are maintained even after multiple wash cycles. Brief description of the drawings

[0022] An implementation of the present technology is described, by way of example only, with reference to the attached figure, in which:

[0023] Figure [Fig.l] shows strands of hair treated according to the methods of the present disclosure and compares them to strands of hair not treated according to the methods of the present disclosure.

[0024] Figure [Fig.2] shows other strands of hair not treated according to methods of the present disclosure.

[0025] The various aspects of the disclosure are not limited to the results, arrangements and representations shown in the drawings. DETAILED DESCRIPTION OF THE DISCLOSURE

[0026] The present disclosure relates to methods for treating hair, particularly hair in need of reduced frizz and improved softness. This is achieved by using a hair treatment composition that includes at least one acyclic carbonate ester having a plurality of C6-C18 fatty chains. The inventors believe that at least one acyclic carbonate ester having a plurality of C6-C18 fatty chains undergoes a reaction when subjected to heat treatment. For example, heat may activate a reaction with the carbonate and amine groups of hair fibers, resulting in the grafting of a fatty alkyl chain onto the hair or the likely formation of an N,N'-disubstituted urea bond that contributes to long-lasting benefits. The methods are gentle, long-lasting, and reduce hair frizz while simultaneously improving smooth texture. The methods improve fiber alignment, reduce frizz, and impart smooth texture to a surprising degree. The longevity of the improved fiber alignment, reduced frizz, and smooth texture is also significant and surprising.Hair treated in accordance with the processes described here retains these desirable cosmetic properties, even after multiple cleaning cycles. Thus, the benefits provided by the compositions are surprisingly long-lasting and resistant to washing.

[0027] Methods in accordance with the present disclosure typically comprise:

In other preferred embodiments, the amino-functionalized silicone is amodimethicone.

[0093] The total amount of the one or more silicones in the compositions will vary. However, in various embodiments, the compositions include about 0.1 to about 10% by weight of the one or more silicones, based on the total weight of the composition. In other embodiments, the compositions include about 0.1 to about 8% by weight, about 0.1 to about 6% by weight, about 0.1 to about 5% by weight, about 1 to about 10% by weight, about 1 to about 8% by weight, about 1 to about 6% by weight, about 1 to about 5% by weight, about 2 to about 10% by weight, about 2 to about 8% by weight, about 2 to about 6% by weight, about 2 to about 5% by weight, about 3 to about 10% by weight, about 3 to about 8% by weight, or about 3 to about 6% by weight or about 3 to about 5% by weight of the one or more silicones, based on the weight of the composition.

[0094] In a preferred embodiment, the hair treatment compositions include one or more amino-functionalized silicones. In other embodiments, the hair treatment compositions include one or more amino-functionalized silicones and are free or essentially free of other silicones, i.e., the composition is free or essentially free of silicones other than the one or more amino-functionalized silicones. In additional embodiments, the hair treatment composition includes amodimethicone and is free or essentially free of silicones other than amodimethicone.

[0095] The total amount of one or more amino-functionalized silicones in the compositions will vary.

(d) (Film-forming polymers)

[0096] The hair treatment compositions of the present disclosure optionally include one or more film-forming polymers, for example, one or more film-forming polymers selected from cationic film-forming polymers, anionic film-forming polymers, non-ionic film-forming polymers, amphoteric film-forming polymers, or a combination thereof.

[0097] Various types of film-forming polymers overlap with the scope of the one or more polysaccharides (component (e)) and the one or more non-ionic associative polymeric thickeners (component (f)). Indeed, various film-forming polymers, polysaccharides and non-ionic associative polymeric thickeners can contribute to the formation of films on the hair and provide a thickening effect to the hair treatment compositions.

[0098] In such cases where an overlap may exist and where the treatment composition hair treatment composition includes two or more overlapping components, a single compound does not represent more than one component. For example, if a hair treatment composition includes a film-forming polymer, a polysaccharide, and a non-ionic associative thickener, a single compound cannot act as all three components. Similarly, a single compound cannot simultaneously act as two components.

[0099] In various embodiments, the hair treatment composition includes one or more film-forming polymers. The term "hydrophilic film-forming polymer" is interchangeable with the term "aqueous film-forming polymer" and refers to polymers or copolymers that may be water-soluble or water-dispersible; anionic, cationic, or non-ionic; and crosslinked or non-crosslinked. They generally include polar groups such as hydroxyl, amide, amine, or ether groups, and other groups having a high affinity for water. In addition, they must provide good adhesive, bonding, film-forming, and water-swelling properties. Hydrophilic polymers are film-forming polymers capable of forming, by themselves or in the presence of an auxiliary film-forming agent, a continuous film capable of adhering to a support, especially the skin.

[0100] Non-limiting examples of hydrophilic film-forming polymers include polyurethanes, vinyl polymers, natural polymers, latex polymers, vinylpyrrolidone (VP)-based polymers, amphoteric polymers, and mixtures thereof.

[0101] (i) Polyurethanes

[0102] The polyurethanes may be aliphatic, cycloaliphatic or aromatic copolymers, polyurea-urethanes or polyurea copolymers, comprising, alone or as a mixture: at least one block of aliphatic and / or cycloaliphatic and / or aromatic polyester origin, and / or at least one branched or unbranched silicone block, for example polydimethylsiloxane or polymethylphenylsiloxane, and / or at least one block comprising fluoro groups.

[0103] The film-forming polyurethanes which can be used in the invention can also be obtained from branched or unbranched polyesters or from alkyls comprising labile hydrogens, which are modified by reaction with a dii-isocyanate and a difunctional organic compound (e.g. dihydroxy, diamino or hydroxyamino), also comprising either a carboxylic acid or carboxylate group, or a sulfonic acid or sulfonate group, or alternatively a neutralizable tertiary amine group or a quaternary ammonium group.

[0104] For the purpose of forming the polyurethane, monomers bearing an anionic group which can be used during the polycondensation which may be mentioned include dimethylolpropionic acid, trimellitic acid or a derivative such as the anhydride trimellitic acid, 3-sulfopentanediol sodium salt and 5-sulfo-1,3-benzenedicarboxylic acid salt of salt of salt. Preferably, the monomer bearing an anionic group is dimethylolpropionic acid.

[0105] As film-forming polyurethane which can be used according to the invention, mention may therefore be made of the aqueous polyurethane dispersions sold under the names Avalure UR-405®, Avalure UR-410®, Avalure UR-425® and Avalure UR-450® by the company Goodrich. A particularly preferred polyurethane is polyurethane-99.

[0106] Advantageously, the film-forming polyurethanes are chosen from copolymers obtained by copolymerization of hexanediol, neopentyl glycol, adipic acid, hexamethylene diisocyanate, N-(2-aminoethyl)-3-aminoethanesulfonic acid and ethylenediamine. Preferably, the polyurethanes may also be chosen from copolymers obtained by copolymerization of adipic acid, dicyclohexylmethane diisocyanate, ethylenediamine, hexanediol, neopentyl glycol and sodium N-(2-aminoethyl)-3-aminoethanesulfonate.

[0107] In particular, the polyurethanes are chosen from those sold under the name Baycusan eco E 1001, Baycusan C1001 or C1004, known as polyurethane-99, poly-urethane-35, and more particularly the product sold under the name Baycusan C1001, known as polyurethane-99.

[0108] (ii) Vinyl polymers

[0109] The vinyl polymers may be chosen from polyvinyl alcohols, copolymers derived from C4-C8 monounsaturated carboxylic acids or anhydrides, and methyl vinyl ether / butyl monomaleate copolymers. For the purposes of the present invention, the term "polyvinyl alcohol" denotes a polymer comprising -CH2CH(OH)- units. Polyvinyl alcohols are generally produced by hydrolysis of polyvinyl acetate. Usually, the reaction occurs in the presence of methanol (alcoholysis). The reaction is normally catalyzed by acid or base catalysis. The degree of hydrolysis of commercial products is variable, often around 87%, but products with a degree of hydrolysis of 100 also exist. There are also copolymers with monomers other than vinyl acetate, such as ethylene / vinyl alcohol copolymers.

[0110] The polyvinyl alcohol polymers are preferably chosen from homopolymers or copolymers with vinyl acetate, the latter corresponding in particular to a partial hydrolysis of polyvinyl acetate.

[0111] For example, it is possible to use the products from the Celvol range supplied by the company Cenese under the names Celvol 540, Celvol 350, Celvol 325, Celvol 165, Celvol 125, Celvol 540 S, Celvol 840 and Celvol 443.

[0112] The copolymer(s) derived from C4-C8 monounsaturated carboxylic acids or anhydrides may be chosen from copolymers comprising (i) one or several maleic, fumaric or itaconic acids or anhydrides and (ii) one or more monomers selected from vinyl esters, vinyl ethers, vinyl halides, phenylvinyl derivatives, and acrylic acid and its esters, the anhydride functions of these copolymers being optionally monoesterified or monoamidated, for example, INCI name: Butyl Ester of PVM / MA Copolymer. Preferably, the copolymer(s) derived from C4-C8 monounsaturated carboxylic acids or anhydrides is / are selected from monoesterified copolymers of methyl vinyl ether / maleic anhydride, for example, the ethyl ester of PVM / MA copolymer, sold under the name Gantrez ES 225 by the company ISP.

[0113] (iii) Natural polymers

[0114] The hydrophilic polymers may also be chosen from natural polymers, in particular polysaccharides which have monosaccharides or disaccharides as basic units. The natural polymers are preferably chosen from pullulan, guar gums and modified guar gums, celluloses and gellan gum, and their derivatives.

[0115] In a preferred embodiment, a natural hydrophilic film-forming polymer is pullulan. Pullulan is a polysaccharide polymer consisting of maltotriose units, also known as 'α-1,4-α1,6-glucan'. Three glucose units in maltotriose are connected by an α-1,4 glycosidic linkage, while consecutive maltotriose units are connected to each other by an α-1,6 glycosidic linkage. In various embodiments, the compositions include pullulan and optionally one or more additional hydrophilic film-forming polymers, e.g., one or more polyurethanes. In this situation, the amount of pullulan will vary. However, in various embodiments, the compositions include about 1 to about 15% by weight of the pullulan, based on a total weight of the skin-perfecting composition.In other embodiments, the skin-perfecting composition includes from about 1 to about 15 wt. %, from about 1 to about 12 wt. %, from about 1 to about 10 wt. %, from about 1 to about 8 wt. %, from about 2 to about 15 wt. %, from about 2 to about 12 wt. %, from about 2 to about 10 wt. %, from about 2 to about 8 wt. %, from about 3 to about 15 wt. %, from about 3 to about 12 wt. %, from about 3 to about 10 wt. %, from about 3 to about 8 wt. %, based on the total weight of the skin-perfecting composition.

[0116] Guar gums are galactomannans consisting of mannose and galactose. As used herein, the term "modified guar gum" refers to guar gums alkylated with at least one C1-C8 alkyl group, guar gums hydroxyalkylated with at least one C1-C8 hydroxyalkyl group, and guar gums alkylated with at least one C1-C8 acyl group. Guar gums Hydroxypropyl esters (e.g., hydroxypropyl guar) such as the product sold under the name Jaguar HP 105 by the Rhodia company are a useful example.

[0117] Cellulose is a [31-4-polyacetal of cellobiose, cellobiose being a disaccharide consisting of two glucose molecules. Cellulose derivatives can be cationic, amphoteric or non-ionic. Among these derivatives, cellulose ethers, cellulose esters and cellulose ester ethers are distinguished. Among the non-ionic cellulose ethers, mention may be made of alkylcelluloses such as methylcelluloses and ethylcelluloses; hydroxyalkylcelluloses, such as hydroxymethylcelluloses, hydroxyethylcelluloses and hydroxypropylcelluloses; and mixed hydroxyalkylcelluloses such as hydroxypropylmethylcelluloses, hydroxyethylmethylcelluloses, hydroxyethylethylcelluloses and hydroxybutylmethylcelluloses.

[0118] Among the cationic cellulose ethers, mention may be made of crosslinked or non-crosslinked quaternized hydroxyethylcelluloses. The quaternizing agent may in particular be glycidyltrimethylammonium chloride or a fatty amine such as laurylamine or stearylamine. Another cationic cellulose ether that may be mentioned is hydroxypropyltrimethylammonium hydroxyethylcellulose. Among the cellulose esters are inorganic cellulose esters (cellulose nitrates, sulfates, phosphates, etc.), organic cellulose esters (cellulose monoacetates, triacetates, amidopropionates, acetatebutyrates, acetatepropionates and acetatetrimellitates, etc.) and mixed organic / inorganic cellulose esters, such as cellulose acetatebutyrate sulfates and cellulose acetatepropionate sulfates.

[0119] Among the cellulose ester ethers, mention may be made of hydroxypropylmethylcellulose phthalates and ethylcellulose sulfates. The cellulose-based compounds of the invention may be chosen from unsubstituted celluloses and substituted celluloses.

[0120] Celluloses and derivatives are represented, for example, by the products sold under the names Avicel® (microcrystalline cellulose, MCC) by the company FMC Biopolymers, under the names MethocelTM (cellulose ethers) and Ethocel™ (ethylcellulose) by the company Dow, Benecel® (methylcellulose), Blanose™ (carboxymethylcellulose), Culminai® (methylcellulose, hydroxymethylcellulose), Klucel® (hydroxypropylcellulose), Polysurf® (cetylhydroxyethylcellulose) and Natrosol® CS (hydroxyethylcellulose) by the company Hercules Aqualon.

[0121] Gellan gum is a polysaccharide produced by aerobic fermentation of Sphingomonas elodea, more commonly known as Pseudomonas elodea. This linear polysaccharide is formed from the following monosaccharide sequence: D-glucose, D-glucuronic acid and L-rhamnose. In its native form, gellan gum is highly acylated. Gellan gum preferably used in the film according to the present invention is a gellan gum which is at least partially deacylated. This at least partially deacylated gellan gum is obtained by alkaline treatment at high temperature. For example, a KOH or NaOH solution will be used. The purified gellan gum sold under the trade name Kelcogel® by the company Kelco is suitable for the preparation of the compositions according to the invention.

[0122] Gellan gum derivatives are all products obtained by carrying out standard chemical reactions, in particular esterifications, the addition of a salt of an organic or mineral acid. Welan gum is for example used as a gellan gum derivative. Welan gum is a gellan gum modified by fermentation using the strain Alcaligenes ATCC 31 555. Welan gum has a recurring pentasaccharide structure formed by a main chain composed of D-glucose, D-glucuronic acid and L-rhamnose units, onto which a pendant L-rhamnose or L-mannose unit is grafted. Welan gum (diutan gum) sold under the trade name Kelco Crete® by the company Kelco is suitable for the preparation of the compositions according to the invention.

[0123] As other saccharide polymers which can be used according to the invention, mention may be made of starches and their derivatives.

[0124] Natural hydrophilic film-forming polymers include celluloses and their derivatives, in particular those sold under the name Avicel® (microcrystalline cellulose, MCC) by the company FMC Biopolymers.

[0125] Carrageenans are anionic polysaccharides constituting the cell walls of various red algae (Rhodophyceae) belonging to the families Gigartinaceae, Hypneaceae, Furcellariaceae and Polyideaceae. They are generally obtained by hot aqueous extraction from natural strains of said algae. These linear polymers, formed by disaccharide units, are composed of two D-galactopyranose units linked alternately by α(1,3) and β(1,4) bonds. They are highly sulfated polysaccharides (20% to 50%) and the α-D-galactopyranosyl residues can be in 3,6-anhydro form.Depending on the number and position of sulfate ester groups on the repeating disaccharide of the molecule, several types of carrageenans are distinguished, namely: kappa-carrageenans, which carry one sulfate ester group, iota-carrageenans, which carry two sulfate ester groups, and lambda-carrageenans, which carry three sulfate ester groups. Carrageenans are composed mainly of potassium, sodium, magnesium, triethanolamine and / or calcium salts of polysaccharide sulfate esters.

[0126] Carrageenans are sold in particular by the company SEPPIC under the name Solagum®, by the company Gelymar under the names Carragel®, Carralact® and Carrasol®, by the company Cargill under the names Satiagel™ and Satiagum™, and by the company CP-Kelco under the names Genulacta®, Genugel® and Genuvisco®.

[0128] A useful hydrophilic film-forming polymer is xanthan gum and modified xanthan gums, such as dehydroxanthan gum, hydroxypropyl xanthan gum, and mixtures thereof. In some cases, dehydroxanthan gum is useful.

[0129] (iv) Latex or pseudolatex polymers

[0130] As presented above for hydrophilic film-forming polyurethanes, the hydrophilic film-forming polymer may therefore also be present in a composition of the invention in the form of particles dispersed in an aqueous phase, generally known as latex or pseudolatex. The techniques for preparing these dispersions are well known to those skilled in the art.

[0137] The term "polysaccharides" refers to compounds containing a backbone of repeating sugar units (i.e., carbohydrates). The polysaccharides may be cationic, non-ionic, or anionic. In various embodiments, the polysaccharides are preferably non-ionic polysaccharides.

[0138] Non-limiting examples of polysaccharides include starches, gums, celluloses, and mixtures thereof.

[0144] (f) Non-ionic associative polymeric thickeners

[0145] An associative thickener is capable of reversibly associating with itself or with other molecules or particles. This physical association provides thickening and can give rise to thixotropic or shear-thinning macromolecular systems, that is, systems whose viscosity depends on the shear forces to which they are subjected.

[0146] In various embodiments, the non-ionic associative polymer thickener is a non-ionic associative polyurethane thickener, preferably a non-ionic associative polyurethane / polyether. The non-ionic polyurethanes / polyethers may have both at least one hydrophilic moiety and at least one hydrophobic moiety. More particularly, said polymers may contain in their chain both hydrophilic sequences, most often of a polyoxyethylenated nature, and hydrophobic sequences which may be aliphatic bonds alone and / or cycloaliphatic and / or aromatic bonds. In various embodiments, these polyether-polyurethanes comprise at least two lipophilic hydrocarbon chains, having from 6 to 30 carbon atoms, preferably from 6 to 20, separated by a hydrophilic sequence, knowing that the hydrocarbon chains may be pendant chains or chains at the end of a hydrophilic sequence.In particular, it is possible that one or more pendant chains are envisaged. In addition, the polymer may comprise a hydrocarbon chain at one end or at both ends of a hydrophilic sequence.

[0147] Polyether polyurethanes may be polyblocks, particularly in triblock form. The hydrophobic sequences may be at each end of the chain (for example: triblock copolymer carrying a hydrophilic central sequence) or distributed both at the ends and in the chain (for example, multiblock copolymer). These same polymers may also be in the form of graft units or be star-shaped.

[0148] Nonionic polyether / polyurethanes containing a fatty chain may be triblock copolymers whose hydrophilic block is a polyoxyethylenated chain comprising from 50 to 1000 oxyethylenated groups. Nonionic polyether-polyurethanes comprise a urethane linkage between the hydrophilic blocks, hence the origin of the name. By extension, those whose hydrophilic blocks are linked by other chemical bonds to the hydrophobic blocks are also included among the nonionic polyether-polyurethanes containing a hydrophobic chain.

[0149] Non-limiting examples of non-ionic polyethers / polyurethanes containing a hydrophobic chain include Rheolate® 205 containing a urea functional group sold by the company RHEOX or alternatively Rheolates® 208, 204 or 212, as well as Acrysol RM 184®. Other products include ELFACOS T210® containing an alkyl chain in C12-C14 and AKZO's ELFACOS T212® containing a C18 alkyl chain. ROHM & HAAS's DW 1206B® containing a C20 alkyl chain and a urethane bond, sold at 20% solids in water, can also be used.

[0150] It is also possible to use solutions or dispersions of these polymers, in particular in water or in an aqueous-alcoholic medium. Examples of these polymers include Rheolate® 255, Rheolate® 278 and Rheolate® 244 sold by the company RHEOX. It is also possible to use the products DW 1206F and DW 1206J supplied by the company ROHM & HAAS.

[0166] Furthermore, it is possible to use a polyisocyanate having a urethane bond obtained by reacting said polyisocyanate compound and a polyol. As the polyol, di- to octahydric polyols are preferable, and the polyols listed above are preferable. In cases where one or more trihydric polyisocyanates are used as the polyisocyanate which is represented by the formula R3—(NCO)n+l, it is preferable to use said polyisocyanate having the urethane linkage.

[0253] A: Inventive

[0254] B: Comparison

[0255] Tests were conducted on strands of curly hair (medium bleached hair with a 2b curl pattern) to determine how the compositions in the table above affected the hair. All strands of hair were washed with the same standard shampoo. The shampoo was rinsed from the strands of hair and the strands of hair were towel dried. The wet strands of hair were then treated with one of the compositions shown in the table above (approximately 1 gram of composition per gram of hair). All compositions were left on the hair for 10 minutes. After 10 minutes, the above compositions were rinsed from the strands of hair and the strands were blow-dried. After drying by After blow-drying the strands, the strands were treated with a hot flat iron at a temperature of approximately 232°C. The hair was passed through the hot iron three times, rinsed, and air-dried to restore its curly nature. After treatment, the strands were visually assessed for smoothness, softness, alignment, and frizz control on a scale of 1 to 5, where 1 is consistent with poor performance and 5 is consistent with excellent performance. The strands were then placed in a humidity chamber with a humidity of 80% and a temperature of 25°C for two hours. After two hours, the strands were again visually assessed for smoothness, softness, alignment, and frizz control on a scale of 1 to 5.The strands were then washed with the same standard shampoo for 3 times, then air-dried and again assessed for smoothness, softness, alignment and frizz control on a scale of 1 to 5. The strands were then placed in a humidity chamber with 80% humidity and 25°C for two hours. After two hours, the strands were again visually assessed for smoothness, softness, alignment and frizz control on a scale of 1 to 5. The invented treatment (B) gave the hair long-lasting smoothness and frizz control compared to the control (A). Example 2

The foregoing description illustrates and describes the disclosure. In addition, the disclosure shows and describes only the preferred embodiments. However, as mentioned above, it is to be understood that it is suitable for use in various other combinations, modifications, and environments and is suitable for changes or modifications within the scope of the inventive concepts as expressed herein, consistent with the above teachings and / or the skill or knowledge of the relevant art. The embodiments described herein are further intended to explain the best modes known to the applicant and to enable others skilled in the art to use the disclosure in such or other embodiments, and with the various modifications required by the particular applications or uses thereof. Accordingly, the description is not intended to limit the invention to the form disclosed herein. The appended claims are also intended to be construed to include other embodiments.

[0263] As used herein, the terms "comprising," "having," and "including" are used in their broad and non-limiting sense.

[0264] The terms "a," "an," "the," and "the" are understood to encompass both the plural and the singular. Thus, the expression "a mixture of" also relates to "mixtures of." Throughout the disclosure, the expression "their mixture" is used, after a list of elements as shown in the following example where the letters A through F represent the elements: "one or more elements selected from the group consisting of A, B, C, D, E, F, and their mixture." The expression "their mixture" does not require that the mixture include all of A, B, C, D, E, and F (although all of A, B, C, D, E, and F may be included). Rather, it indicates that a mixture of two or more of A, B, C, D, E, and F may be included. In other words, it is equivalent to the formulation "one or more elements selected from the group consisting of A, B, C, D, E, F, and a mixture of two or more of A, B, C, D, E and F".

[0265] Similarly, the expression "their salt" also relates to "their salts". Thus, when the disclosure refers to "an element selected from the group consisting of A, B, C, D, E, F, their salt, and a mixture thereof", it indicates that one or more of A, B, C, D and F may be included, one or more of a salt of A, a salt of B, a salt of C, a salt of D, a salt of E and a salt of F may be included, or a mixture of any two of A, B, C, D, E, F, a salt of A, a salt of B, a salt of C, a salt of D, a salt of E and a salt of F may be included.

[0266] Salts referred to throughout the disclosure may include salts having a counterion such as an alkali metal, an alkaline earth metal, or an ammonium counterion. This list of counterions, however, is not limiting. Suitable counterions for the components described herein are known in the art.

[0267] The expression “one or more” means “at least one” and therefore includes individual components as well as mixtures / combinations.

[0268] The term "plurality" means "more than one" or "two or more."

[0269] Except in the working examples, or if otherwise indicated, all numbers expressing quantities of ingredients and / or reaction conditions may be modified in all cases by the term "about", meaning to within + / - 5% of the number noted.

[0270] All percentages, parts and ratios herein are based on the total weight of the compositions of the present invention, unless otherwise indicated.

[0271] Some of the various identified component categories may overlap. In such cases where an overlap may exist and the composition includes both components (or the composition includes more than two overlapping components), an overlapping compound does not represent more than one component. For example, some compounds may be considered both a nonionic surfactant or emulsifier and a fat component. If a particular composition includes both a nonionic surfactant or emulsifier and a fat compound, a single compound will serve solely as the nonionic surfactant or emulsifier or solely as the fat component (the single compound does not serve as both a nonionic surfactant or emulsifier and a fat component).

[0272] A "rinse-out" product refers to a composition that is rinsed and / or washed from the hair with water after or during application of the composition to the hair, and before drying and / or styling the hair. At least a portion of the composition is removed from the hair during rinsing and / or washing.

[0273] A "leave-in" product refers to a composition that is not rinsed and / or washed out of the hair after or during application of the composition to the hair. The composition remains on the hair during drying and / or throughout styling.

[0274] As used herein, all ranges provided are intended to include each specific range within the given ranges, as well as a combination of intermediate subranges. Thus, a range of 1 to 5 specifically includes 1, 2, 3, 4, and 5, as well as subranges such as 2 to 5, 3 to 5, 2 to 3, 2 to 4, 1 to 4, etc. All ranges and values ​​disclosed herein are inclusive and combinable. For example, any value or point described herein that falls within a range described herein may serve as a minimum or maximum value to derive a subrange, etc.

[0275] The composition of the present case optionally includes one or more surfactants and / or emulsifiers, e.g., one or more nonionic, anionic, cationic, and / or amphoteric / zwitterionic surfactants. The terms "surfactants" and "emulsifiers" include salts of the surfactants and emulsifiers even if not explicitly stated. In other words, whenever the disclosure refers to a surfactant or emulsifier, it is intended that salts also be encompassed to the extent such salts exist, even though the specification may not specifically refer to a salt (or may not refer to a salt in all instances throughout the disclosure), e.g., by using language such as "their salt" or "their salts." Sodium and potassium are common cations that form salts with surfactants and emulsifiers. However, sup cations Additional ions such as ammonium ions, or alkanolammonium ions such as monoethanolammonium or triethanolammonium ions, can also form surfactant salts.

[0276] The term "substantially free" or "essentially free" as used herein means that less than about 2% by weight of a specific material is added to a composition, based on the total weight of the compositions. However, the compositions may include less than about 1% by weight, less than about 0.5% by weight, less than about 0.1% by weight, or none of the specified material.

[0277] Any components positively presented in the present disclosure may be negatively excluded from the claims, for example, a claimed composition may be "free", "essentially free" (or "substantially free") of one or more components that are positively presented in the present disclosure.
