Description

Title of the invention: COMPOSITION FOR KERATINOUS FIBERS COMPRISING A BETAINE COMPOUND technical field

[0001] The present invention relates to a composition for keratin fibers comprising at least one betaine compound, in particular a hair care composition comprising at least one betaine compound, as well as a cosmetic process using the composition. STATE OF THE ART

[0002] It is well known that the smoothing and softening effect of hair products is widely appreciated by customers. It is also well known that a hair conditioner is recommended for treating damaged hair that has been sensitized (i.e., damaged and / or weakened) to varying degrees by atmospheric agents or by mechanical or chemical treatments, such as dyeing, bleaching, and / or perming. When damaged, hair is often difficult to detangle and lacks softness. It is well known in the industry to use a hair conditioner in hair washing or conditioning formulations to facilitate detangling and achieve a softening and smoothing effect.

[0003] Part of the prior art discloses compositions for the care of keratinous fibers.

[0004] For example, WO 2013 / 189037 discloses a personal care composition comprising a pearly revitalizing composition comprising: a) at least one fatty alcohol containing a fatty chain with at least 22 carbon atoms, b) at least one fatty amide,

[0005] c) at least one alkylpolyglycoside, and d) at least one revitalizing agent.

[0006] However, there is still a demand for cosmetic compositions that can offer keratin fibers enhanced revitalizing effects, such as effects that impart softness and smooth texture to keratin fibers, and that have increased viscosity because viscosity is essential to provide consumers with revitalizing indices. DISCLOSURE OF THE INVENTION

[0007] An objective of the present invention is to provide a composition which can offer keratinous fibers such as hair an improved revitalizing effect, such as effects giving softness and smooth texture to keratinous fibers, and which has increased viscosity without weighing down keratinous fibers such as hair.

[0026] the optional rinsing of the keratinous fiber composition. Best embodiment of the invention

[0027] After extensive research, the inventors made an astonishing discovery that adding the specific amount of (d) betaine compound to the combination of ingredients (a) to (c) can increase the viscosity of the composition without weighing down keratinous fibers such as hair, as well as giving the hair improved softness and smooth texture, and thus finalized the invention.

[0028] Thus, the composition according to the present invention comprises: a. at least one fatty alcohol having a carbon chain containing 20 to 26 carbon atoms; b. at least one fatty amide; c. at least one sugar ether surfactant; and d. at least one betaine compound in an amount of at least 1.5% by weight per relative to the total weight of the composition.

[0029] The present invention can provide keratinous fibers such as hair with an improved softening and smoothing effect. Thus, the composition according to the present invention can be intended for the revitalization and / or care of keratinous fibers.

[0030] The term "keratinous fibers" here refers to fibers containing keratin as their main constituent, and examples include hair, eyelashes, eyebrows, and the like.

Thus, keratinous fibers treated with the composition according to the present invention can exhibit a desired viscous property. The viscosity of cosmetic compositions, particularly hair care cosmetic compositions, is very important because it is essential for providing consumers with repair signals. The inventors of the present invention have discovered, surprisingly, that adding the specific amount of (d) betaine compound to the specific combinations of ingredients (a) to (c) can achieve an appropriate viscosity as well as the desired revitalizing effects.

These sugars may be monosaccharides, oligosaccharides, or polysaccharides.

[0123] Examples of suitable sugars include sucrose, glucose, galactose, ribose, fucose, maltose, fructose, mannose, arabinose, xylose and lactose and their derivatives, in particular alkylated derivatives, such as methylated derivatives, for example methylglucose.

[0124] Sugar esters of fatty acids may be selected in particular from the group comprising the esters or mixtures of esters of sugars described above and of fatty acids in the range of C6-C30, and preferably C12-C22, linear or branched, saturated or unsaturated. If unsaturated, these compounds may have one to three conjugated or non-conjugated carbon-carbon double bonds.

[0133] The term "fatty" in fatty alcohol means the inclusion of a relatively large number A significant number of carbon atoms are considered essential. Thus, alcohols with 4 or more carbon atoms, preferably 6 or more, and more preferably 12 or more, fall within the category of fatty alcohols. Fatty alcohols can be saturated or unsaturated. They can be linear or branched.

[0134] The fatty alcohol as an optional oily ingredient is selected from fatty alcohols other than (a) fatty alcohols having a carbon chain containing 20 to 26 carbon atoms. Thus, the fatty alcohol as an optional oily ingredient may be selected from fatty alcohols having a carbon chain containing 4 to 19 carbon atoms and / or fatty alcohols having a carbon chain containing 27 or more carbon atoms.

[0135] The fatty acids that may be used in the composition of this disclosure may be saturated or unsaturated and may comprise from 6 to 30 carbon atoms such as from 9 to 30 carbon atoms.

[0151] hydrophilic thickener. A single type of hydrophilic thickener or a combination of different types of hydrophilic thickeners may be used. The term "hydrophilic" here refers to materials soluble in water at a concentration of 1% by weight or more relative to the total weight of water at room temperature (25 °C) and atmospheric pressure (105 Pa). The hydrophilic thickener(s) may be natural or synthetic. The hydrophilic thickener(s) may preferably be chosen from among thickening polymers bearing sugar motifs, such as non-associative thickening polymers bearing sugar motifs. For the purposes of the present invention, the term "sugar motif" means an oxygen-bearing hydrocarbon compound containing several alcohol functions, with or without aldehyde or ketone functions, and comprising at least 4 carbon atoms. Sugar patterns can optionally be modified by substitution, and / or by oxidation and / or by dehydration. The sugar motifs that can be included in the hydrophilic thickening polymers of the present invention are preferably derived from one or more of the following sugars: glucose, galactose, arabinose, rhamnose, mannose, xylose, fucose, anhydrogalactose, galacturonic acid, glucuronic acid, mannuronic acid, galactose sulfate, anhydrogalactose sulfate and fructose. It is preferable to choose the thickener from among the polysaccharides. Examples of thickening polymers containing sugar motifs include native gums such as: a. tree or shrub exudates, including: • gum arabic (branched polymer of galactose, arabinose, rhamnose and glucuronic acid); • Ghatti gum (polymer derived from arabinose, galactose, mannose, xylose and glucuronic acid); • karaya gum (polymer derived from galacturonic acid, galactose, rhamnose and glucuronic acid); • Tragacanth gum (polymer of galacturonic acid, galactose, fucose, xylose and arabinose); a.

Plant extracts, including: • cellulose (glucose polymer); • starch (glucose polymer) and • Inulin.

[0152] These polymers can be modified physically or chemically. Temperature can be cited as a physical treatment.

[0153] Chemical treatments that can be cited include esterification, etherification, amidation, and oxidation reactions. These treatments can lead to polymers that may be nonionic, anionic, or amphoteric.

[0154] Preferably, the thickening polymers bearing sugar motifs are not chemically or physically treated.

[0155] The non-ionic guar gums that can be used according to the invention can be modified by (poly)hydroxyalkyl groups in Ci-C6.

[0156] Among the (poly)hydroxyalkyl groups in Ci-C6, examples include hydroxymethyl, hydroxyethyl, hydroxypropyl and hydroxybutyl groups.

[0157] These guar gums are well known in the prior art and can be prepared, for example, by reacting the corresponding alkene oxides, for example, propylene oxides, with guar gum so as to obtain a guar gum modified by hydroxypropyl groups.

[0158] The degree of hydroxyalkylation preferably varies from 0.4 to 1.2 and corresponds to the number of alkylene oxide molecules consumed by the number of free hydroxyl functional groups present on the guar gum.

[0159] Such non-ionic guar gums optionally modified by hydroxyalkyl groups are sold, for example, under the trade names Jaguar HP8, Jaguar HP60 and Jaguar HP120 by the company Rhodia Chimie.

[0160] Among the starches that can be used, examples include macro Molecules in the form of polymers comprise basic units, which are anhydroglucose units. The number of these units and their arrangement allow us to distinguish amylose (a linear polymer) from amylopectin (a branched polymer). The relative proportions of amylose and amylopectin, as well as their degree of polymerization, can vary depending on the botanical origin of the starches.

[0161] The botanical origin of the starch molecules that can be used in the present invention may be cereals or tubers. Thus, the starches are chosen, for example, from maize starch, rice starch, cassava starch, barley starch, potato starch, wheat starch, sorghum starch and pea starch.

[0162] Starches can be modified chemically or physically, in particular by one or more of the following reactions: pregelatinization, oxidation, crosslinking, esterification, etherification, amidation, heat treatments.

[0163] According to the invention, amphoteric starches can also be used, these amphoteric starches comprising one or more anionic groups and one or more cationic groups. The anionic and cationic groups may be linked to the same reactive site of the starch molecule or to different reactive sites; they are preferably linked to the same reactive site. The anionic groups may be of the carboxylic, phosphate, or sulfate type, preferably carboxylic. The cationic groups may be of the primary, secondary, tertiary, or quaternary amine type.

[0164] Starches may optionally be hydroxyalkylated with Ci-C6 or acylated with CrC6 (such as acetylated). Starches may also have undergone heat treatments.

[0165] The non-associative thickening polymers of the invention may be cellulose-based polymers not comprising a Ci0-C30 fatty chain in their structure.

[0166] According to the invention, the expression "cellulose-based polymer" refers to any polysaccharide compound having in its structure sequences of glucose residues linked together via [3-1,4] bonds; in addition to unsubstituted celluloses, cellulose derivatives can be anionic, cationic, amphoteric or non-ionic.

[0167] Thus, the cellulose polymers that can be used according to the invention can be chosen from unsubstituted celluloses, including those in microcrystalline form, and cellulose ethers.

[0168] Among these cellulose-based polymers, we distinguish cellulose ethers, cellulose esters and cellulose ester ethers.

[0169] Cellulose esters include mineral cellulose esters (nitrates, sulfates, phosphates, etc. of cellulose), organic cellulose esters (monoacetates, triacetates, amidopropionates, acetobutyrates, acetopropionates and acetotrimellitates, etc. of cellulose) and mixed organic / mineral cellulose esters, such as cellulose acetobutyrate sulfates and cellulose acetopropionate sulfates. Among the cellulose ester ethers, we can mention hydroxypropylmethylcellulose phthalates and ethylcellulose sulfates.

[0170] Among the non-ionic cellulose ethers without a C10-C30 fatty chain, i.e., which are "non-associative", examples include (C10-C4)alkylcelluloses such as methylcelluloses and ethylcelluloses (e.g., Ethocel Standard 100 Premium from Dow Chemical); (poly)hydroxy(C10-C4)alkylcelluloses, such as hydroxymethylcelluloses, hydroxyethylcelluloses (e.g., Natrosol 250 HHR supplied by Aqualon) and hydroxypropylcelluloses (e.g., Klucel EF from Aqualon); mixed (poly)hydroxy(C10-C4)alkyl-(C10-C4)alkylcelluloses such as hydroxypropylmethylcelluloses (e.g., Methocel E4M from Dow Chemical); hydroxyethyl-methylcelluloses, hydroxyethyl celluloses, (for example, Bermocoll E 481 FQ from Akzo Nobel) and hydroxybutylmethylcelluloses.

[0171] Among the anionic cellulose ethers without a fat chain, (poly)carboxy(Ci-C4)alkylcelluloses and their salts may be mentioned. By way of example, carboxymethylcelluloses, carboxymethylmethylcelluloses (for example Blanose 7M from Aqualon) and carboxymethylhydroxyethylcelluloses, and their sodium salts may be mentioned.

[0172] Among cationic cellulose ethers without a fat chain, cationic cellulose derivatives such as cellulose copolymers or cellulose derivatives grafted with a water-soluble quaternary ammonium monomer may be mentioned, and described in particular in US patent 4,131,576, such as (poly)hydroxy(Ci-C4)alkyl celluloses, for example, hydroxymethyl-, hydroxyethyl-, or hydroxypropylcelluloses grafted in particular with a salt of methacryloylethyltrimethylammonium, methacrylamidopropyltrimethylammonium, or dimethyldiallylammonium. Commercial products corresponding to this definition are, in particular, the products sold under the names Celquat L 200 and Celquat H 100 by the National Starch company.

[0173] The degree of hydroxyalkylation, which corresponds to the number of alkylene oxide molecules consumed by the number of free hydroxyl functions present on the guar gum, can, for example, range from 0.4 to 1.2.

[0174] The quantity of hydrophilic thickener(s) in the composition according to the present invention can range from 0.1% to 10% by weight, preferably from 0.3% to 5% by weight, more preferably from 0.5% to 3% by weight, relative to the total weight of the composition.

[0280] The present invention will be described in more detail by means of examples. However, these should not be interpreted as limiting the scope of the present invention. [Preparations]

[0281] Each of the compositions in the form of an oil-in-water emulsion according to Example 1 and Comparative Examples 1 and 2 was prepared by mixing the ingredients listed in Table 1. When melting behenyl alcohol, thickeners, and similar substances, the mixture was heated to 70 °C until the ingredient had completely melted. The numerical values ​​of the quantities of ingredients in Table 1 are all based on the "% by weight" of the ingredients relative to the total weight of the composition, unless otherwise indicated – MA: Active Ingredient. [Assessment] (Viscosity)

[0282] The viscosity of the resulting composition was measured with a Rheomat RM 180 rheometer equipped with a No. 4 spindle at 25 °C. The measurement was carried out for 30 seconds after rotating the spindle in the composition for 1 minute at 200 rpm. (Sensory Appreciation)

[0283] 2.7 g of a strand of bleached Chinese hair with a length of 27 cm were Each hair strand was prepared. It was washed once with a clarifying shampoo. After shampooing, the strand was rinsed with water and then towel-dried. One gram of each of the compositions from Example 1 and Comparative Examples 1 and 2 was applied to the hair strand, which was then left for 5 minutes at room temperature. The hair strand was then rinsed with water and blow-dried to obtain the treated hair.

[0284] The sensory aspects of softness and smooth texture of the treated hair were evaluated by several panelists in a hair care domain with scores from 1 to 3 in accordance with the following criteria and were averaged.

[0296] ** : sold by DOW under the trade name XIAMETER MEM-8299 EMULSION (containing 56% to 61% active ingredient)

[0297] *2: sold by BASF under the trade name PLANTAREN 2000 UP (containing ap (approximately 53% active ingredient)

[0298] As can be seen from the tables, the compositions according to Example 1, which include the specific combination of ingredients (a) to (d), exhibited improved softening and smoothing efficacy and the desired increased viscosity. Since the composition exhibits improved revitalizing effects, such as imparting softness and a smooth texture to keratin fibers, it can be said that it does not weigh down the keratin fibers.

[0299] On the other hand, the compositions according to Comparative Example 1, which do not include the (d) betaine compound, could not exhibit good softening and smoothing efficacy on keratinous fibers. Furthermore, the viscosity of the composition according to Comparative Example 1 was insufficient. Moreover, the composition according to Comparative Example 2, which includes only 1% by weight of the betaine compound, could not exhibit good softening and smoothing efficacy on keratinous fibers. Furthermore, the viscosity of the composition according to Comparative Example 2 was insufficient.

[0300] Consequently, it can be said that the composition according to the present invention is very suitable as a cosmetic composition for the treatment of keratinous fibers, such as hair, because it can offer keratinous fibers the improved cosmetic effect of softening and smoothing keratinous fibers, and also exhibit a desired increased viscosity without weighing down the hair.
