Detergent cosmetic compositions containing an anionic surfactant derived from amino acids and salts thereof and a soluble conditioning agent and uses thereof

[0001] The present invention relates to novel cosmetic compositions comprising, in a cosmetically acceptable medium, at least one anionic surfactant chosen from the N-acylated compounds of mono- and polyamidated polycarboxylic amino acids and the salts of said acids and at least one particular soluble conditioning agent.

[0002] The use of detergent compositions (shampoos and shower gels) based essentially on conventional surfactants of the anionic, nonionic and/or amphoteric type, but more particularly of the anionic type, is common for cleansing and/or washing the hair and/or the skin. These compositions are applied to wet hair or skin and the foam generated by massaging or rubbing with the hands allows, after rinsing with water, the removal of the various types of dirt initially present on the hair or the skin.

[0003] These base compositions indeed possess good washing power, but the intrinsic cosmetic properties attached to them remain nevertheless fairly weak, in particular because of the fact that the relatively aggressive nature of such a cleansing treatment can cause in the long term damage to the keratinous materials which is marked to a greater or lesser degree, linked in particular to the gradual removal of the lipids or proteins contained in or at the surface thereof.

[0004] Accordingly, to improve the cosmetic properties of the above detergent compositions, and more particularly of those that are intended to be applied to sensitive hair (i.e. hair which has become damaged or which has been made fragile especially under the chemical action of atmospheric agents and/or of hair treatments such as permanent waving, dyeing or bleaching), it is now customary to introduce therein additional cosmetic agents called conditioning agents, intended mainly to repair or limit the harmful or undesirable effects induced by the various treatments or attacks to which the hair fibres are subjected more or less repeatedly. These conditioning agents can of course also improve the cosmetic behaviour of natural hair.

[0005] The conditioning agents most commonly used to date in shampoos are cationic polymers, silicones and/or silicone-based derivatives, which indeed confer on washed, dry or wet hair greatly improved ease of disentanglement, softness and sleekness compared to what may be obtained with the corresponding cleansing compositions not containing them.

[0006] However, in spite of the progress recently made in the field of shampoos based on cationic polymers and/or silicone, the latter are not completely truly satisfactory, such that a high demand currently still exists in relation to being able to have novel products exhibiting better performance at the level of at least one of the cosmetic properties mentioned above.

[0007] The N-acylated anionic surfactants of mono- and polyamidated polycarboxylic amino acids and their salts have already been recommended in detergent cosmetic compositions. They have been described, for example, in patent application WO 97/03171, the disclosure of which is hereby incorporated by reference.

[0008] The washing compositions for the hair using these surfactants alone may not lead to completely satisfactory cosmetic properties.

[0009] The aim of the invention is therefore to provide detergent cosmetic compositions having at least one improved cosmetic property, such as disentanglement, sleekness and/or softness of the hair.

[0010] However, the inventors have now found that the combination of particular soluble conditioning agents and a particular anionic surfactant and their salts makes it possible to achieve at least one of these aims.

[0011] These novel compositions can make it possible to better deposit these conditioning agents on keratinous materials (especially the hair) than a composition containing conventional anionic surfactants such as the salts of N-cocoylglutamic acid.

[0012] The compositions in accordance with the invention confer on the keratinous materials, in particular the hair, a remarkable treatment effect which manifests itself in particular by at least one of the properties of lightness, sleekness, softness, suppleness, and ease of disentanglement with minimal sensation of a charged feel.

[0013] The subject of the invention is thus a detergent cosmetic composition, characterized in that it comprises, in a cosmetically acceptable medium, at least one anionic surfactant chosen from the N-acylated compounds of mono- and polyamidated polycarboxylic amino acids and the salts of said acids and at least one soluble conditioning agent chosen from:

[0014] I) anionic polymers,

[0015] II) nonionic polymers,

[0016] III) cationic polymers, such as cationic proteins and hydrolysates of cationic proteins

[0017] IV) amphoteric polymers, and

[0018] V) cationic surfactants chosen from quaternary ammonium salts comprising at least one amide functional group, quaternary ammonium salts of imidazoline, quaternary diammonium salts, quaternary ammonium salts containing at least one ester functional group.

[0019] Another subject of the invention relates to the use of at least one anionic surfactant chosen from the N-acylated compounds of mono- and polyamidated polycarboxylic amino acids and the salts of said acids in, or for the manufacture of a cosmetic composition comprising at least one soluble conditioning agent as defined above.

[0020] Another subject of the invention relates to a method for treating a keratinous material, such as the hair, comprising applying to said material an effective amount of a cosmetic composition according to the invention.

[0021] A subject of the invention is also the use of a composition according to the invention in order to increase at least one of disentanglement and sleeking of the hair, in order to impart at least one of volume, lightness, softness, suppleness and manageability on the hair.

[0022] According to the present invention, the expression keratinous material is understood to encompass the hair, the eyelashes, the eyebrows, the skin, the mucous membranes or the scalp, and more particularly the hair.

[0023] Various aspects of the invention will now be presented in detail. All the meanings and definitions of the compounds used in the present invention given below are valid for all aspects of the invention.

[0024] N-Acylated Anionic Surfactants of Mono and Polyamidated Polycarboxylic Amino Acids

[0025] The N-acylated anionic surfactants of mono- and polyamidated polycarboxylic amino acids and their salts may have the following formula (I):

[0026] in which:

[0027] R is chosen from linear and branched, saturated and unsaturated, hydrocarbon radicals comprising from 5 to 29 carbon atoms. For example, R is chosen from mono- and polyunsaturated alkyl and alkenyl radicals comprising from 5 to 29 carbon atoms and as a further example from 7 to 22 carbon atoms,

[0028] n is an integer chosen from 1 and 2.

[0029] An additional example would be N-acylated compounds of mono- and polyamidated polycarboxylic amino acids of formula (I) in which R is chosen from linear, branched, and saturated alkyl radicals comprising from 7 to 29 carbon atoms, such as from 7 to 22 carbon atoms.

[0030] The salts of the compounds of formula (I) may be salts of alkali metals (for example sodium and potassium), of alkaline-earth metals (which may be, for example, calcium and magnesium), salts of aqueous ammonia, salts of amines such as those of monoethanolamine, diethanolamine, triethanolamine, 3-amino-1,2-propanediol, and ammonium salts derived from basic amino acids such as lysine, arginine, sarcosine, ornithine, citrulline.

[0031] Among the surfactants of formula (I), there may be mentioned for example the salts of N-cocoylglutamine and in particular the triethanolamine salt of N-cocoylglutamine such as the product marketed under the name FOAM UP DOUCE GM by the company KYOWA HAKKO.

[0032] According to the invention, the anionic surfactant(s) chosen from the N-acylated compounds of mono- and polyamidated polycarboxylic amino acids and their salts may, for example, represent from 1% to 30% by weight, such as from 3% to 15% by weight relative to the total weight of the final composition.

[0033] The expression water-soluble conditioning agents is understood to mean conditioning agents soluble in water at a concentration greater than or equal to 0.1% by weight in water at 25° C., that is to say that they form a macroscopically isotropic transparent solution, meaning that the solution is homogeneous to the naked eye and, to the naked eye, has properties that do not vary with direction.

[0257] provided, however, that the sum x+y+z is equal to 1 to 15, that when x is equal to 0, then R16 is R20 and that when z is equal to 0, then R18 is R22.

[0258] For example, R15 can be linear. Further examples of the quaternary diammonium salts are compounds chosen from the formula above wherein R15 is chosen from methyl, ethyl, hydroxyethyl and dihydroxypropyl radicals, R16 is chosen from hydrocarbon radicals R20 having from 12 to 22 carbon atoms and hydrocarbon radicals having from 1 to 3 carbon atoms, R18 is chosen from hydrocarbon radicals R22 having from 1 to 3 carbon atoms, R17, R19 and R21, are chosen from saturated and unsaturated, linear and branched C11-C21 hydrocarbon radicals, such as saturated and unsaturated, linear and branched C11-C21 alkyl and alkenyl radicals, x and z are integers chosen from 0 and 1, y is 1, n, p and r are equal to integers chosen from 2 and 3, such as 2, and/or X− is chosen from halides such as chloride, bromide, and iodide and alkyl sulphates, such as methyl sulphate, methane sulphonate, phosphate, nitrate, tosylate, anions derived from an organic acid such as acetate or lactate, and ammonium compatible anions containing an ester functional group.

[0259] A further example of a quaternary diammonium salt is a compound corresponding to the formula above wherein X− is chosen from chloride and methyl sulphate, and the sum of x +y +z equals an integer from 1 to 10.

[0260] Additional examples of ammonium salts are those of formula (XXIV) in which:

[0261] R15 is chosen from methyl and ethyl radicals;

[0262] x and y are equal to 1;

[0263] z is an integer chosen from 0 and 1;

[0264] n, p and r are equal to 2;

[0265] R16 is chosen from:

[0266] the radical

[0267] methyl, ethyl and C14-C22 hydrocarbon radicals and a hydrogen atom;

[0268] R18 is chosen from:

[0269] the radical

[0270] and a hydrogen atom; and

[0271] R17, R19 and R21, which may be identical or different, are chosen from saturated and unsaturated, linear and branched C13-C17 hydrocarbon radicals, such as saturated and unsaturated, linear and branched C13-C17 alkyl and alkenyl radicals and further such as saturated and unsaturated, linear C13-C17 alkyl and alkenyl radicals.

[0272] There may be mentioned, for example, compounds of formula (XXIV) such as the salts, such as the chloride and methyl sulfate salts, of diacyloxyethyldimethylammonium, diacyloxyethylhydroxyethylmethylammonium, monoacyloxyethyldihydroxyethylmethylammonium, triacyloxyethylmethylammonium, monoacyloxyethylhydroxyethyldimethylammonium and mixtures thereof. The acyl radicals, for example, have 14 to 18 carbon atoms and may be obtained, for example, from a vegetable oil, such as palm and sunflower oil. When the compound contains several acyl radicals, the latter may be identical or different.

[0273] These products are obtained, for example, by direct esterification of optionally oxyalkylenated triethanolamine, triisopropanolamine, alkyldiethanolamine or alkyldiisopropanolamine with fatty acids or with mixtures of fatty acids of plant or animal origin or by transesterification of their methyl esters. This esterification is followed by quaternization using an alkylating agent such as an alkyl (such as methyl and ethyl) halide, a dialkyl (such as methyl and ethyl) sulphate, methyl methanesulphonate, methyl para-toluenesulphonate, glycol and glycerol chlorohydrin.

[0274] Such compounds are, for example, marketed under the names DEHYQUART by the company HENKEL, STEPANQUAT by the company STEPAN, NOXAMIUM by the company CECA, and REWOQUAT WE 18 by the company REWO-WITCO.

[0275] Thus, for example, the composition of the invention may contain a mixture of quaternary ammonium mono-, di- and triester salts with a majority, by weight, of diester salts.

[0276] Examples of the mixture of ammonium salts include the mixture containing 15 to 30% by weight of acyloxyethyldihydroxyethylmethylammonium methyl sulphate, 45 to 60% of diacyloxyethylhydroxyethylmethylammonium methyl sulphate and 15 to 30% of triacyloxyethylmethyl-ammonium methyl sulphate, the acyl radicals having from 14 to 18 carbon atoms and being obtained from optionally partially hydrogenated palm oil.

[0277] The ammonium salts containing at least one ester functional group which are disclosed in Patents U.S. Pat. No. 4,874,554 and U.S. Pat. No. 4,137,180, the disclosures of which are hereby incorporated by reference, may also be used.

[0278] According to the invention, the soluble conditioning agent(s) according to the invention may, for example, represent from 0.001% to 20% by weight, for example, from 0.01% to 10% by weight, such as from 0.05 to 3% by weight, relative to the total weight of the final composition.

[0279] The compositions of the invention may also contain, in addition, at least one other surfactant which is, for example, present in a quantity of from 0.1% to 40% by weight approximately, for example from 3% to 30%, such as from 5% to 20%, relative to the total weight of the composition.

[0280] This surfactant may be chosen from anionic, amphoteric and nonionic surfactants, and mixtures thereof.

[0281] Additional surfactants for carrying out the present invention can be chosen from the following:

[0282] (i) Anionic Surfactant(s):

[0283] Their nature may not be of critical importance within the context of the present invention.

[0284] Thus, by way of example of anionic surfactants that can be employed, by themselves or as mixtures, in the context of the present invention, there may be mentioned (nonlimiting list) the salts (for example alkali metal salts such as sodium, ammonium salts, amine salts, amino alcohol salts and magnesium salts) of the following compounds: alkyl sulphates, alkyl ether sulphates, alkylamido ether sulphates, alkylaryl-polyether sulphates, monoglyceride sulphates, alkyl sulphonates, alkyl phosphates, alkylamidesulphonates, alkyl aryl sulphonates, α-olefinsulphonates, paraffin-sulphonates, alkyl sulphosuccinates, alkyl ether sulphosuccinates, alkylamidesulphosuccinates, alkyl sulphosuccinamates, alkyl sulphoacetates, alkyl ether phosphates, acyl sarcosinates, acyl isethionates and N-acyltaurates, the alkyl or acyl radical of all these different compounds containing from 8 to 24 carbon atoms, and the aryl radical chosen from a phenyl and benzyl group. Among the anionic surfactants there may also be mentioned the salts of fatty acids such as the salts of oleic, ricinoleic, palmitic and stearic acids, the acids of copra oil or of hydrogenated copra oil, and acyl lactylates in which the acyl radical contains 8 to 20 carbon atoms. Weakly anionic surfactants may also be employed such as alkyl-D-galactosideuronic acids and salts thereof, as well as the polyoxyalkylenated carboxylic (C6-C24)alkyl ether acids, the polyoxyalkylenated carboxylic (C6-C24)alkylaryl ether acids, the polyoxyalkylenated carboxylic (C6-C24)alkyl amidoether acids and their salts, such as those containing from 2 to 50 ethylene oxide groups and mixtures thereof.

[0285] Additional examples of anionic surfactants include the salts of alkyl sulphates and of alkyl ether sulphates and mixtures thereof.

[0286] (ii) Nonionic Surfactant(s):

[0287] The nonionic surfactants themselves are also compounds which are well known per se (in this respect see the “Handbook of Surfactants” by M. R. Porter, published by Blackie & Son (Glasgow and London), 1991, pp. 116-178) and, in the context of the present invention, their nature may not be of critical importance. They can thus be chosen from (nonlimiting list) alcohols, alpha-diols, alkylphenols and polyethoxylated, polypropoxylated or polyglycerolated fatty acids which have a fatty chain containing, for example, 8 to 18 carbon atoms, it being possible, for example, for the number of ethylene oxide or propylene oxide groups to range from 2 to 50 and it being possible, for example, for the number of glycerol groups to range from 2 to 30. The copolymers of ethylene oxide and propylene oxide and the condensates of ethylene oxide and propylene oxide with fatty alcohols may also be mentioned by way of example. Examples of these copolymers and condensates include the polyethoxylated fatty amides containing, for example, from 2 to 30 mol of ethylene oxide, the polyglycerolated fatty amides on average containing, for example, 1 to 5 glycerol groups, such as 1.5 to 4, the polyethoxylated fatty amines containing, for example, 2 to 30 mol of ethylene oxide, the oxyethylenated fatty acid esters of sorbitan containing, for example, from 2 to 30 mol of ethylene oxide, the fatty acid esters of sucrose, the fatty acid esters of polyethylene glycol, alkylpolyglycosides, N-alkylglucamine derivatives, amine oxides such as the oxides of (C10-C14) alkylamines, and the N-acylaminopropylmorpholine oxides. Alkylpolyglycosides are still another example of nonionic surfactants for the present invention.

[0288] (iii) Amphoteric Surfactant(s):

[0289] The additional amphoteric surfactants, the nature of which may not be of critical importance in the context of the present invention, may be (nonlimiting list) chosen from derivatives of aliphatic secondary and tertiary amines in which the aliphatic radical is chosen from linear and branched chains comprising 8 to 22 carbon atoms and comprising at least one water-solubilizing anionic group (for example carboxylate, sulphonate, sulphate, phosphate or phosphonate); (C8-C20)alkylbetaines, sulphobetaines, (C8-C20)alkylamido(C1-C6)alkylbetaines and (C8-C20)alkylamido(C1-C6)al kylsulphobetaines.

[0290] Among the amine derivatives there may be mentioned the products sold under the name Miranol, as described in U.S. Pat. No. 2,528,378 and U.S. Pat. No. 2,781,354, the disclosures of which are hereby incorporated by reference and of structures:

R2—CONHCH2CH2—N(R3)(R4)(CH2COO—) (2)

[0291] in which: R2 is chosen from alkyl radicals derived from an acid R2—COOH present in hydrolysed copra oil, such as a heptyl, nonyl and undecyl radicals;

[0292] R3 is a beta-hydroxyethyl group; and R4 is chosen from a carboxymethyl group and

R5—CONHCH2CH2—N(B)(C) (3)

[0293] in which:

[0294] B is chosen from —CH2CH2OX′;

[0295] (C) represents —(CH2)2—Y″, wherein z is an integer chosen from 1 and 2;

[0296] X′ is chosen from the radical —CH2CH2—COOH and a hydrogen atom;

[0297] Y′ is chosen from —COOH and the radical —CH2—CHOH—SO3H; and

[0298] R5 is chosen from alkyl radicals of a carboxylic acid present in an oil chosen from copra oil and hydrolysed linseed oil, such as C7, C9, C11, C13, and C17 alkyl radicals, iso C17 alkyl radicals and unsaturated C17 radicals.

[0299] These compounds are classified in the CTFA dictionary, 7th edition, 1997, under the names Disodium Cocoamphodiacetate, Disodium Lauroamphodiacetate, Disodium Capryloamphodiacetate, Disodium Caproamphodiacetate, Disodium Cocoamphodipropionate, Disodium Lauroamphodipropionate, Disodium Caproampho-dipropionate, Disodium Capryloamphodipropionate, Lauro-amphodipropionic acid, and Cocoamphodipropionic acid.

[0300] By way of example, there may be mentioned the commercial product of disodium cocoamphodiacetate marketed under the trade name MIRANOL® C2M concentrate by the company RHODIA CHIMIE.

[0301] Thus, representative compositions of the invention may include mixtures of surfactants such as mixtures of anionic surfactants and mixtures of anionic surfactants and amphoteric and/or nonionic surfactants.

[0302] Examples of such mixtgures of surfactants include the following anionic surfactants: sodium, triethanolamine and ammonium (C12-C14)alkyl sulphates, oxyethylenated sodium, triethanolamine and ammonium (C12-C14)alkyl ether sulphates containing 2.2 mol of ethylene oxide, sodium cocoyl isethionate and sodium (C14-C16)alphaolefin sulphonate mixed with an amphoteric surfactant.

[0303] The amphoteric surfactant in such representative mixtures may, for example, be chosen from the amine derivatives called disodium cocoamphodipropionate and sodium cocoamphopropionate marketed by the company RHODIA CHIMIE under the trade name “MIRANOL® C2M CONC” in aqueous solution at 38% of active substance or under the name MIRANOL® C32 and alkylbetaines, such as cocobetaine marketed under the name “DEHYTON® AB 30” in aqueous solution at 32% AS by the company HENKEL and the (C8-C20)alkylamido(C1-C6)alkylbetaines, such as TEGOBETAINE® F 50 marketed by the company GOLDSCHMIDT.

[0304] Anionic surfactant(s) different from the N-acylated compounds of mono- and polyamidated polycarboxylic amino acids according to the invention are generally, for example, present in an amount of about 1 to about 30% by weight such as 3 to 15% by weight, relative to the total weight of the composition.

[0305] The amphoteric or nonionic surfactant(s) are generally present, for example, in an amount of about 0.5 to about 15% by weight such as from 1 to 5% by weight, relative to the total weight of the composition.

[0306] The quantity and the quality of the surfactants are those sufficient to confer a satisfactory foaming and/or detergent power on the final composition.

[0307] In the composition according to the present invention, all the detergent surfactants generally, for example, represent from 4 to 50% by weight, for further example, from 6 to 35% by weight such as from 8 to 25% by weight relative to the total weight of the composition.

[0308] The composition of the invention may also contain at least one additive chosen from thickeners, perfumes, pearlescent agents, preservatives, sunscreens, silicones, ceramides, pseudoceramides, linear and branched chain C16-C40 acids such as 18-methyleicosanoic acid, hydroxy acids, vitamins, provitamins such as panthenol, vegetable oils, mineral oils and synthetic oils, antidandruff agents and any other additive conventionally used in the cosmetic field which does not affect the stability and the properties of the compositions according to the invention.

[0309] These additives may be present in the composition according to the invention in proportions which may, for example, range from 0.0001 to 50% by weight relative to the total weight of the composition. The precise quantity of each additive is easily determined by a person skilled in the art according to its nature and its function.

[0310] The cosmetically acceptable medium may consist solely of water or the cosmetically acceptable medium may comprise a mixture of water and a cosmetically acceptable solvent, for example, a lower C1-C4 alcohol, such as ethanol, isopropanol, tert-butanol and n-butanol, and alkylene glycols, such as propylene glycol and glycol ethers. By way of example, the composition may comprise from 50 to 95% by weight of water relative to the total weight of the composition.

[0311] The detergent compositions according to the invention have a final pH which is generally, for example, from 3 to 10, such as a pH from 4 to 8. The adjustment of the pH to the desired value may be carried out conventionally by addition of a base (organic or inorganic) to the composition, for example aqueous ammonia and primary, secondary and tertiary (poly)amines, such as monoethanolamine, diethanolamine, triethanolamine, isopropanolamine and 1,3-propanediamine, or by the addition of an acid, for example a carboxylic acid such as citric acid.

[0312] The compositions in accordance with the invention may comprise, in addition to the combination defined above, viscosity-regulating agents such as electrolytes or thickening agents. As examples there may be mentioned sodium chloride, scleroglucans, xanthan gums, fatty acid alkanolamides, alkyl ether carboxylic acid alkanolamides which are optionally oxyethylenated with up to 5 mol of ethylene oxide, such as the product marketed under the name “AMINOL A15” by the company CHEM Y, crosslinked polyacrylic acids and crosslinked acrylic acid/C10-C30 alkyl acrylate copolymers. These viscosity-regulating agents are used in the compositions according to the invention in proportions which may be up to 10% by weight relative to the total weight of the composition.

[0313] The compositions in accordance with the invention may also contain up to 5% of pearlescent or opacifying agents well known in the state of the art, such as sodium and magnesium palmitates, sodium and magnesium stearates and hydroxystearates, fatty chain-containing acylated derivatives, such as ethylene glycol and polyethylene glycol monostearates and distearates, and fatty chain-containing ethers such as distearyl ether and 1-(hexadecyloxy)-2-octadecanol.

[0314] The compositions according to the invention may also contain foam synergists selected from C10-C18 1,2-alkanediols and fatty alkanolamides derived from mono- and diethanolamine.

[0315] The compositions in accordance with the invention may be used for washing and treating a keratinous material such as the hair, the skin, the eyelashes, the eyebrows, the nails, the lips, the scalp. A common example would be treatement of hair.

[0316] Examples of the detergent compositions according to the invention are shampoos, shower gels and foam baths. The compositions of the invention may also be provided in the form of rinse-off after-shampoos and leave-in after-shampoos, of compositions for permanent waving, straightening, dyeing or bleaching, or in the form of rinse-off compositions, to be applied before or after dyeing, bleaching, permanent waving or straightening or between the two stages of permanent waving or straightening. The compositions of the invention may also be provided in the form of make-up removing products.

[0317] The compositions according to the invention may be provided in forms selected from gels, milks, creams, emulsions, thickened lotions thickened foams and may be used for the skin, the scalp, the nails, the eyelashes, the lips and the hair.

[0318] These detergent compositions may be foaming and the foaming power of the compositions according to the invention, characterized by a foam height, is generally greater than 75 mm, such as greater than 100 mm, measured according to the modified ROSS-MILES method (NF T 73-404/ISO696). The modified method is as follows: The measurement is carried out at the temperature of 22° C. with osmosed water. The concentration of the solution is 2 g/l. The drop height is 1 m. The quantity of composition which drops is 200 ml. These 200 ml of composition fall into a measuring cylinder having a diameter of 50 mm and containing 50 ml of the composition tested. The measuring is made 5 minutes after stopping the flow of the composition.

[0319] The subject of the invention is also a method for treating a keratinous material, such as the skin and the hair, characterized in that it comprises applying to the keratinous material a cosmetic composition as defined above, and then optionally rinsing off, with water, for example.

[0320] Thus, the method according to the invention allows the treatment of, care of, washing of, and/or removal of make-up from the skin, the hair or any other keratinous material.

[0321] In the text which follows or in the preceding text, the percentages expressed are by weight. The invention will now be illustrated more fully with the aid of the following examples which cannot be considered as limiting the embodiments described. In the examples, AS means active substance.
