Composition for treating keratinous materials, comprising a hydroxycarboxylic acid and a protective and/or conditioning agent

[0002] The invention relates to a composition for treating keratinous materials, preferably human keratinous fibers such as the hair, comprising, in a physiologically and preferably cosmetically acceptable medium, at least one of protective and conditioning agent, and at least one particular hydroxycarboxylic acid, or salts thereof.

BACKGROUND OF THE INVENTION

[0003] It is well known that hair is sensitized or embrittled to varying degrees by the action of atmospheric agents and especially of light, water and humidity, and also by the repeated action of various hair treatments such as washing, permanent-waving, relaxing, dyeing and bleaching. Many publications disclose that natural light destroys certain amino acids of the hair. Since these attacks impair the hair fiber, they reduce its mechanical properties, for instance the tensile strength, the breaking load and the elasticity, or its resistance to swelling in an aqueous medium. The hair then becomes dull, coarse and brittle. In contrast with the skin, the hair becomes lighter in colour.

[0004] It is also known that the light and washing agents have a tendency to attack the natural colour of the hair, and also the artificial colour of dyed hair. The colour of the hair gradually fades or changes to shades that are unattractive or undesirable.

[0005] Substances for protecting the hair against the degradations caused by atmospheric attack, such as the light and heat, and treatments, have been sought for many years in the cosmetics industry. Preferably, products are sought that protect the colour of naturally coloured or artificially dyed keratinous fibers and that preserve or reinforce the intrinsic mechanical properties of the keratinous fibers (tensile strength, breaking load and elasticity, or their resistance to swelling in an aqueous medium).

[0006] To combat these degradations of hair keratin, it has already been proposed to use certain substances capable of screening out light radiation, for instance 2-hydroxy-4-methoxybenzophenone-5-sulphonic acid or salts thereof (FR-A-2 627 085), 4-(2-oxo-3-bornylidenemethyl)benzenesulphonic acid or salts thereof (EP-A-329 032) or lactoferrin (FR-A-2 673 839).

[0007] However, when these screening agents are efficient, they are only efficient at high concentrations. However, at these concentrations, hair treated with these screening agents has a coarse, laden feel. Furthermore, such hair is extremely difficult to disentangle.

[0008] It has already been recommended, in compositions for washing or caring for keratinous materials such as the hair, to use conditioning agents, preferably cationic polymers or silicones, to facilitate the disentangling of the hair and to give it softness and suppleness. However, the cosmetic advantages mentioned above are unfortunately also accompanied, on dried hair, by certain cosmetic effects considered undesirable, namely heaviness of the hairstyle (lack of lightness of the hair), and lack of smoothness (hair that is not uniform from the root to the tip).

[0009] In addition, the use of cationic polymers for this purpose presents various drawbacks. On account of their high affinity for the hair, some of these polymers become deposited in large amounts during repeated use, and lead to adverse effects such as an unpleasant, laden feel, stiffening of the hair or adhesion between the fibers, which affects the styling. These drawbacks are accentuated in the case of fine hair, which lacks liveliness and volume.

[0010] It is well known that hair that has been sensitized (i.e., damaged and/or embrittled) to varying degrees by the action of atmospheric agents or by the action of mechanical or chemical treatments, such as dyeing, bleaching and/or permanent-waving, is often difficult to disentangle and to style, and lacks softness.

[0011] In summary, it is found that the current cosmetic compositions containing protective and/or conditioning agents are not entirely satisfactory.

[0012] Moreover, cosmetic compositions generally contain a complexing agent for complexing the metal cations liable to be present in trace amounts in these compositions, and also those that may be present on the hair and that originate from the ambient air, from the water with which this hair has been washed, or from shampoos or other hair products with which the hair has been treated. Specifically, it is very important to neutralize these metal cations, since they are capable of catalysing the oxidation reactions of hair fibers, and of doing so in an uncontrolled manner, which may be reflected by severe adverse effects such as brittleness of the hair or burning of the scalp.

DETAILED DESCRIPTION

[0013] The complexing agents most commonly used at the present time in oxidizing compositions for dyeing, bleaching or permanently reshaping keratinous fibers are ethylenediaminetetraacetic acid (EDTA) and its derivatives, for instance diethylenetriaminepentaacetic acid (DPTA), generally in weight proportions of about from 0.1% to 1%.

[0014] However, in the context of its research, the Applicant has found that EDTA and derivatives thereof have insufficient complexing properties in compositions of this type. These findings, which are corroborated by the results obtained by other research teams, justify the search for novel complexing agents.

SUMMARY OF THE INVENTION

[0015] A complexing agent intended to form part of the constitution of cosmetic compositions must satisfy numerous requirements. Specifically, in addition to the fact that it must have high complexing power with respect to metals, so as to eliminate or, at the very least, minimize the risk of catalysis of oxidation reactions on the keratinous fibers by the metallic traces liable to be present in these compositions and on these fibers, it must be compatible, and preferably must not react, with the other constituents. It must also be stable in solution. It must also be totally harmless to these fibers and to the skin, and must preferably be lacking in any allergenic nature.

[0016] The Applicant has now discovered that the combination of a particular complexing agent with protective and/or conditioning agents makes it possible to increase the deposition of the agent for protecting or conditioning keratinous materials and thereby to increase the protection or conditioning.

[0017] An improvement in the cosmetic properties is observed, such as, preferably, the ease of styling, the hold, the liveliness or the volume of the treated hair.

[0018] All these discoveries form the basis of the present invention.

[0019] Thus, according to the present invention, novel cosmetic compositions are now proposed, comprising, in a physiologically and preferably cosmetically acceptable medium, at least one particular agent for protecting or conditioning keratinous materials and at least one particular hydroxycarboxylic acid or salts thereof.

[0020] One preferred embodiment of the invention is thus a composition for treating keratinous materials, preferably human keratinous fibers such as the hair, comprising, in a physiologically and preferably cosmetically acceptable medium, at least one hydroxycarboxylic acid or salts thereof corresponding to the general formula (I) below:

R—(CHOH)4—CO2X (I)

[0021] in which:

[0022] R represents a group CO2X, and

[0023] X represents a hydrogen atom or a monovalent or divalent cation derived from a transition metal, from an alkali metal or alkaline-earth metal, from an organic amine or from an ammonium ion,

[0024] and at least one of protective agent and conditioning agent, the said conditioning agent being chosen from synthetic oils, plant oils, fluoro or perfluoro oils, natural or synthetic waxes, silicones, non-polysaccharide cationic polymers, compounds of ceramide type, cationic surfactants, fatty amines, fatty acids and derivatives thereof, and also mixtures of these various compounds.

[0025] Another preferred embodiment of the invention relates to the use of at least one particular hydroxycarboxylic acid or salts thereof in, or for the manufacture of, a cosmetic composition comprising an agent for protecting or conditioning keratinous materials.

[0026] Yet another preferred embodiment of the invention is also the use of at least one particular hydroxycarboxylic acid or salts thereof in a composition comprising an agent for protecting or conditioning keratinous materials, to increase the efficacy of this agent for protecting or conditioning keratinous materials.

[0027] Another preferred embodiment of the present invention is also the use of at least one particular hydroxycarboxylic acid or salts thereof in a composition comprising an agent for protecting or conditioning keratinous materials, to improve the deposition and/or fixing of the said protective and/or conditioning agent on the keratinous materials.

The teaching of these two patent applications is included in its entirety in the present application by way of reference.

[0298] The term “fluorohydrocarbon compounds” denotes compounds whose chemical structure contains a carbon skeleton in which certain hydrogen atoms have been replaced with fluorine atoms.

[0299] The fluoro oils can also be fluorocarbons such as fluoroamines, for example perfluorotributylamine, fluorohydrocarbons, for example perfluorodecahydronaphthalene, fluoro esters and fluoro ethers.

[0300] The perfluoropolyethers are sold, for example, under the trade names Fomblin by the company Montefluos and Krytox by the company Du Pont.

[0301] Among the fluorohydrocarbon compounds, mention may also be made of fluorine-containing fatty acid esters such as the product sold under the name Nofable FO by the company Nippon Oil.

[0302] Needless to say, it is possible to use mixtures of conditioning agents.

[0305] This surfactant may be chosen from anionic, amphoteric, nonionic surfactants, or mixtures thereof.

[0306] The surfactants that are suitable for carrying out the present invention are preferably the following:

[0307] (i) Anionic Surfactant(s):

[0308] In the context of the present invention, their nature does not represent a truly critical factor.

[0309] Thus, as examples of anionic surfactants which can be used, alone or as mixtures, in the context of the present invention, mention may be made preferably (non-limiting list) of salts (preferably alkaline salts, preferably sodium salts, ammonium salts, amine salts, amino alcohol salts or magnesium salts) of the following compounds: alkyl sulphates, alkyl ether sulphates, alkylamido ether sulphates, alkylarylpolyether sulphates, monoglyceride sulphates; alkyl sulphonates, alkyl phosphates, alkylamide sulphonates, alkylaryl sulphonates, α-olefin sulphonates, paraffin sulphonates; alkyl sulphosuccinates, alkyl ether sulphosuccinates, alkylamide sulphosuccinates; alkyl sulphosuccinamates; alkyl sulphoacetates; alkyl ether phosphates; acyl sarcosinates; acyl isethionates and N-acyltaurates, the alkyl or acyl radical of all of these various compounds preferably containing from 8 to 24 carbon atoms, and the aryl radical preferably denoting a phenyl or benzyl group.

[0311] (ii) Nonionic Surfactant(s):

[0312] The nonionic surfactants are, themselves also, compounds that are well known per se (see for example in this respect “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 is not a critical feature. Thus, they can be chosen preferably from (non-limiting list) polyethoxylated, polypropoxylated or polyglycerolated fatty acids, alkylphenols, α-diols or alcohols having 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 preferably from 2 to 50 and for the number of glycerol groups to range preferably from 2 to 30. Mention may also be made of copolymers of ethylene oxide and of propylene oxide, condensates of ethylene oxide and of propylene oxide with fatty alcohols; polyethoxylated fatty amides preferably having from 2 to 30 mol of ethylene oxide, polyglycerolated fatty amides containing on average 1 to 5, and preferably 1.5 to 4, glycerol groups; oxyethylenated fatty acid esters of sorbitan having 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 (C10-C14)alkylamine oxides or N-acylaminopropylmorpholine oxides. It will be noted that the alkylpolyglycosides constitute nonionic surfactants that are particularly preferred in the context of the present invention.

[0313] (iii) Amphoteric Surfactant(s):

[0314] The amphoteric surfactants, whose nature is not a critical feature in the context of the present invention, can be, preferably (non-limiting list), aliphatic secondary or tertiary amine derivatives in which the aliphatic radical is a linear or branched chain containing 8 to 22 carbon atoms and containing at least one water-soluble anionic group (for example carboxylate, sulphonate, sulphate, phosphate or phosphonate); mention may also be made of (C8-C20) alkylbetaines, sulphobetaines, (C8-C20) alkylamido (C1-C6) alkylbetaines or (C8-C20) alkylamido (C1-C6) alkylsulphobetaines.

[0315] Among the amine derivatives, mention may be made of the products sold under the name Miranol, as described in U.S. Pat. Nos. 2,528,378 and 2,781,354 and having the structures:

R2—CONHCH2CH2—N(R3)(R4)(CH2COO—) (2)

[0316] in which: R2 denotes an alkyl radical derived from an acid R2—COOH present in hydrolysed coconut oil, a heptyl, nonyl or undecyl radical, R3 denotes a β-hydroxyethyl group and R4 denotes a carboxymethyl group; and

R5—CONHCH2CH2—N(B)(C) (3)

[0322] These compounds are classified in the CTFA dictionary, 5th edition, 1993, under the names disodium cocoamphodiacetate, disodium lauroamphodiacetate, disodium caprylamphodiacetate, disodium capryloamphodiacetate, disodium cocoamphodipropionate, disodium lauroamphodipropionate, disodium caprylamphodipropionate, disodium capryloamphodipropionate, lauroamphodipropionic acid, cocoamphodipropionic acid.

[0323] By way of example, mention may be made of the cocoamphodiacetate sold under the trade name Miranol C2M Concentrate by the company Rhodia Chimie.

[0324] In the compositions in accordance with the invention, mixtures of surfactants are preferably used, and preferably mixtures of anionic surfactants and mixtures of anionic surfactants and of amphoteric or nonionic surfactants. One mixture that is particularly preferred is a mixture consisting of at least one anionic surfactant and of at least one amphoteric surfactant.

[0325] The anionic surfactant preferably used is chosen from sodium, triethanolamine or ammonium (C12-C14)alkyl sulphates, sodium, triethanolamine or ammonium (C12-C14)alkyl ether sulphates oxyethylenated with 2.2 mol of ethylene oxide, sodium cocoyl isethionate and sodium α-(C14-C16)olefin sulphonate, and mixtures thereof, with:

[0326] either an amphoteric surfactant such as the amine derivatives known as disodium cocoamphodipropionate or sodium cocoamphopropionate sold preferably by the company Rhodia Chimie under the trade name Miranol C2M CONC as an aqueous solution containing 38% active material, or under the name Miranol C32;

[0327] or an amphoteric surfactant of zwitterionic type such as alkylbetaines, preferably the cocobetaine sold under the name Dehyton AB 30 as an aqueous solution containing 32% AM by the company Cognis.

[0328] The composition of the invention may also contain at least one additive chosen from thickeners, fragrances, nacreous agents, preserving agents, anionic or nonionic polymers, non-cationic proteins, non-cationic protein hydrolysates, 18-methyleicosanoic acid, hydroxy acids, polymers other than those of the invention and preferably polyether nonionic or cationic associative polyurethanes, and any other additive conventionally used in cosmetics that does not affect the properties of the compositions according to the invention.

[0329] These additives are present in the composition according to the invention in proportions that may range from 0 to 20% by weight relative to the total weight of the composition. The precise amount of each additive is readily determined by a person skilled in the art, depending on its nature and its function.

[0330] The compositions in accordance with the invention may be used more preferably for washing or treating keratinous materials such as the hair, the skin, the eyelashes, the eyebrows, the nails, the lips or the scalp, and more preferably the hair.

[0331] Preferably, the compositions according to the invention are detergent compositions such as shampoos, shower gels and bubble baths. In this embodiment of the invention, the compositions comprise a washing base, which is generally aqueous.

[0332] The surfactant(s) forming the washing base may be chosen, without discrimination, alone or as mixtures, from the anionic, amphoteric and nonionic surfactants as defined above.

[0333] The quantity and quality of the washing base are those that are sufficient to give the final composition satisfactory foaming power and/or detergent power.

[0334] Thus, according to the invention, the washing base can represent from 4% to 50% by weight, preferably from 6% to 35% by weight and even more preferably from 8% to 25% by weight, relative to the total weight of the final composition. Preferably, the washing base contains at least 3% by weight and more preferably from 4% to 30% by weight of anionic surfactants relative to the total weight of the composition.

[0335] The pH of the composition applied to the keratinous materials is generally between 2 and 11. It is preferably between 3 and 8, and may be adjusted to the desired value by means of acidifying or basifying agents that are well known in the prior art for compositions applied to keratinous materials.

[0336] Among the basifying agents that may be mentioned, for example, are aqueous ammonia, alkali metal carbonates, alkanolamines such as monoethanolamine, diethanolamine and triethanolamine and also derivatives thereof, oxyethylenated and/or oxypropylenated hydroxyalkylamines and ethylenediamines, sodium hydroxide, potassium hydroxide and the compounds of formula (XX) below:

[0337] in which R is a propylene residue optionally substituted with a hydroxyl group or a C1-C4 alkyl radical; R38, R39, R40 and R41, which may be identical or different, represent a hydrogen atom, a C1-C4 alkyl radical or a C1-C4 hydroxyalkyl radical.

[0338] The acidifying agents are conventionally, for example, mineral or organic acids, for instance hydrochloric acid, orthophosphoric acid, carboxylic acids, for instance tartaric acid, citric acid or lactic acid, or sulphonic acids.

[0339] The physiologically and preferably cosmetically acceptable medium may consist solely of water, of a cosmetically acceptable solvent or of a mixture of water and a cosmetically acceptable solvent such as a C1-C4 lower alcohol, for instance ethanol, isopropanol, tert-butanol or n-butanol; polyols, for instance propylene glycol, lycerol, diethylene glycol, polyol ethers.

[0340] A subject of the invention is also a process for treating keratinous materials such as the skin or the hair, characterized in that it consists in applying to the keratinous materials a cosmetic composition as defined above, and then in optionally rinsing with water.

[0341] Thus, this process according to the invention allows holding of the hairstyle and the treatment, care or washing of or removal of makeup from the skin, the hair or any other keratin material.

[0342] The compositions of the invention may also be in the form of a rinse-out or leave-in conditioner, permanent-waving, hair-relaxing, dyeing or bleaching compositions, or alternatively in the form of rinse-out compositions to be applied before or after dyeing, bleaching, permanent-waving or relaxing the hair, or alternatively between the two steps of a permanent-waving or hair-relaxing operation.

[0343] The compositions of the invention may also be in the form of washing compositions for the skin, preferably in the form of bath or shower solutions or gels or makeup-removing products.

[0344] The compositions according to the invention may also be in the form of aqueous or aqueous-alcoholic lotions for skincare and/or haircare.

[0345] The cosmetic compositions according to the invention may be in the form of a gel, a milk, a cream, an emulsion, a thickened lotion or a mousse and may be used for the skin, the nails, the eyelashes, the lips and, more preferably, the hair.

[0346] The compositions may be packaged in various forms, preferably in vaporizers, pump-dispenser bottles or in aerosol containers to allow the composition to be applied in vaporized form or in the form of a mousse. Such packaging forms are indicated, for example, when it is desired to obtain a spray, a lacquer or a mousse for treating the hair.

[0347] Throughout the text hereinabove and hereinbelow, the percentages expressed are on a weight basis.

[0348] The invention will now be illustrated more fully with the aid of the examples that follow, which cannot be considered as limiting it to the embodiments described.

[0349] In the examples, AM means active material.
