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

Description

[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 silicone.

[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 fibers 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 poly-amidated 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 silicones and a particular anionic surfactant makes it possible to achieve at least one of these aims.

[0011] These novel compositions can make it possible to better deposit these silicones on a keratinous material such as 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 ease of disentanglement, lightness, sleekness, softness and suppleness 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 silicone.

[0014] 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 silicone.

[0015] Another subject of the invention relates to a method for treating a keratinous material, such as hair, comprising applying to said materials an effective amount of a cosmetic composition according to the invention. 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.

[0016] According to the present invention, the expression keratinous material is understood to encompass the hair, the eyelashes, the eyebrows, the skin, the nails, the mucous membranes or the scalp, and as a common example the hair.

[0017] 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 the aspects of the invention.

N-acylated Anionic Surfactants of Mono and Polyamidated Polycarboxylic Amino Acids

[0018] The N-acylated anionic surfactants of mono- and polyamidated polycarboxylic amino acids and their salts may have the following formula (I):

[0019] in which:

[0020] 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, and

[0021] n is an integer chosen from 1 and 2.

[0022] An additional example would be the 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.

[0023] 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, and citrulline.

[0024] 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.

[0025] According to the invention, the at least one anionic surfactant 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.

[0026] Silicones

[0027] The silicones which may be used in accordance with the invention may be soluble or insoluble in water or in the final composition. They may be volatile or nonvolatile.

[0028] Polyorganosiloxanes are an example of the silicones which may be used in accordance with the invention, the polyorganosiloxanes being insoluble in the composition. Polyorganosiloxanes may be provided in a form chosen from oils, waxes, resins and gums.

[0029] The insoluble silicones are dispersed in the compositions in the form of particles generally having a mean size in numerical terms of between 2 nanometres and 100 microns, for example, between 20 nanometres and 20 microns. As will be recognized by one skilled in the art, the mean size of the particles may be measured by a technique suitable for the size measurement being taken, for example, for particles essentially spherical, by scattering techniques such as static light scattering in which a laser granulometer such as MALVERN or an optical particle counter such as Coulter counter by Coultronix may be employed, and dynamic light scattering, in which a laser granulometer such as Brookhaven is employed.

[0030] The organopolysiloxanes are defined in greater detail in the book by Walter NOLL “Chemistry and Technology of Silicones” (1968) Academie Press.

[0031] The organopolysiloxanes may be volatile or nonvolatile. Volatile silicones may be chosen, for example, from those possessing a boiling point of between 60° C. and 260° C. Additional examples of volatile silicones include those silicones chosen from:

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 and polyglycerolated fatty acids which have a fatty chain containing, for example, 8 to 18 carbon atoms, it being possible for the number of ethylene oxide or propylene oxide groups to range from 2 to 50 and it being possible 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. Further examples are chosen from polyethoxylated fatty amides containing for example from 2 to 30 mol of ethylene oxide, polyglycerolated fatty amides containing for example 1 to 5 glycerol groups, such as 1.5 to 4, polyethoxylated fatty amines containing for example 2 to 30 mol of ethylene oxide, oxyethylenated fatty acid esters of sorbitan containing, for example, from 2 to 30 mol of ethylene oxide, fatty acid esters of sucrose, fatty acid esters of polyethylene glycol, alkylpolyglycosides, N-alkylglucamine derivatives, amine oxides such as the oxides of (C10-C14) alkylamines, and N-acylaminopropylmorpholine oxides. Alkylpolyglycosides are still another example of nonionic surfactants for the present invention.

[0129] (iii) Amphoteric surfactant(s):

[0130] The additional amphoteric surfactants, the nature of which may not be of critical importance in the context of the present invention, may be chosen from (nonlimiting list) derivatives of aliphatic secondary and tertiary amines in which the aliphatic radical is chosen from linear and branched chains containing 8 to 22 carbon atoms and containing at least one water-solubilizing anionic group (for example carboxylate, sulphonate, sulphate, phosphate and phosphonate); (C8-C20)alkylbetaines, sulphobetaines, (C8-C20)alkylamido(C1-C6)alkylbetaines and (C8-C20)alkylamido(C1 -C6)alkylsulphobetaines.

[0131] 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 and of structures chosen from:

R2 —CONHCH2 CH2 —N(R3)(R4)(CH2COO—) (2)

[0132] in which R2 is chosen from alkyl radicals derived from R2—COOH acids present in hydrolysed copra oil, such as a heptyl, nonyl and undecyl radical; R3 is a beta-hydroxyethyl group; and R4 is chosen from a carboxymethyl group and

R5—CONHCH2CH2—N(B)(C) (3)

[0133] in which:

[0169] The modifications of the method are the following:

[0170] 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.

[0171] The subject of the invention is also a method for treating a keratinous material such as skin and hair, characterized in that it comprises applying to the keratinous material an effective amount of a cosmetic composition as defined above, and then in optionally rinsing, such as with water.

[0172] Thus, the method according to the invention allows for at least one of treatment of, care of, washing of and removal of make-up from a keratinous material such as skin hair and any other keratinous material.
