Description

Title of the invention: Cosmetic composition comprising amino acids, hydroxylated (poly)carboxylic acids and associative polymers, and cosmetic treatment method

[0001] The present invention relates to a cosmetic composition, in particular a hair composition, comprising one or more amino acid compounds, one or more hydroxycarboxylic acids, and one or more associative polymers. The invention also relates to a cosmetic treatment method using said composition.

[0002] Consumers around the world generally come into contact with a wide variety of water sources which are not without impact on hair, particularly on its cosmetic properties and / or the performance of hair products.

[0003] So-called mineral waters contain, for example, varying quantities of minerals present in the form of dissolved ions such as calcite (present in the form of calcium), dolomite (present in the form of calcium and magnesium), magnetite (present in the form of iron) and chalcanthite (present in the form of copper). So-called hard waters are also concentrated in minerals such as calcium and magnesium, and swimming pool waters are concentrated in copper salts from algaecides used in swimming pool treatment.

[0004] Hair has a strong tendency to absorb these minerals and / or their metallic salts due to the presence on their surface of anionic functions which correspond in particular to the sulfonic or carboxylic functions of keratin. Furthermore, the isoelectric point of the hair is generally described between 3.2 and 4. As a result, in everyday life, the pH of the water applied to the hair is higher than such values ​​which leads to a negatively charged fiber.

[0005] Minerals, often polyvalent cations, will therefore be attracted and captured by this negatively charged fiber, forming chemical bonds that prevent their release by conventional hair treatment processes. This results in a possible accumulation of minerals on the hair over time. Such fixation depends not only on the hardness of the water, the frequency and / or duration of exposure of the hair to the water in question, but also on the nature and length of the hair (in particular porosity and charge) as well as its state of damage.

[0006] The accumulation of these minerals and / or their metallic salts can cause changes in the hair fiber and, in particular, a more or less marked change in the cosmetic properties of the hair. Thus, an accumulation of calcium and of magnesium can lead to dry, lackluster hair, while a buildup of copper can lead to greening of the hair.

[0007] Furthermore, the accumulation of metallic salts (iron, copper, for example) can accelerate damage to the hair because they catalyze redox reactions and generate HO° hydroxyl radicals which can be harmful to the keratin fiber, even at low levels.

[0008] This can result in photo-degradation of the fiber, lightening of the fiber, as well as an alteration of the properties of the hair, which can lead to premature breakage of the hair; these phenomena are particularly observed during the subsequent use of lightening products or coloring products.

[0009] In other words, hair can become less resistant, more weakened, or even break more easily, or even lose its shine, due to the accumulation of minerals and / or their metallic salts.

[0010] There is therefore a real need to have compositions that make it possible to combat the accumulation of metal ions, originating from minerals and metal salts dissolved in water, or even to make it possible to extract them from keratin fibers, in order to limit their negative impacts and overcome all of the drawbacks mentioned above.

[0011] The composition which is the subject of the present invention, and its implementation, make it possible to achieve this goal.

[0012] The present invention therefore relates to a cosmetic composition, preferably for hair, comprising:

[0013] - one or more amino acid type compounds, preferably present in one total content of at least 0.5% by weight, relative to the total weight of the composition,

[0014] - one or more hydroxylated (poly)carboxylic acids, comprising 2 to 8 atoms of carbon, and / or their salts, preferably present in a total content of at least 0.5% by weight, relative to the total weight of the composition, and

[0015] - one or more associative polymers, preferably present in a total content of at least 0.5% by weight, relative to the total weight of the composition.

[0016] It has been found that the composition according to the invention makes it possible to improve the resistance to breakage of the hair, to strengthen the hair and also to significantly limit its reduction or loss of shine, undesirable effects likely to be caused by the presence of metal ions, in particular copper or calcium, within said fibers.

[0017] After application of the composition, the fibers are as if reinforced, said reinforcement being improved with successive applications of the composition.

[0018] It has also been found that the composition according to the invention also makes it possible to provide conditioning properties to the hair, in particular a feel smoothness, softness, shine and easy detangling, while providing strength, body and a mass effect to the hair.

[0019] It finds a very particular application in the cosmetic treatment, in particular the washing and / or conditioning, of sensitized, weakened and / or damaged keratin fibers, in particular following physical (repeated brushing) and / or chemical treatments, for example coloring, bleaching, perming and / or straightening.

[0020] It is particularly suitable for the cosmetic treatment, in particular the washing and / or conditioning, of keratin fibers loaded with metals, in particular calcium and / or copper, at contents of at least 100 ppm, better still at least 200 ppm; in particular loaded with copper, in particular at contents of at least 100 ppm, better still at least 200 ppm and / or loaded with calcium in particular at contents of at least 4,000 ppm, better still at least 10,000 ppm.

[0021] In what follows, and unless otherwise indicated, the limits of a domain of values ​​are included in this domain, in particular in the expressions “between” and “ranging from ... to ...”.

[0097] in which: R2 represents an alkylene radical having from 1 to 20 carbon atoms, linear or branched, comprising or not a saturated or unsaturated cycle, or an arylene radical, one or more of the carbon atoms being able to be replaced by a heteroatom chosen from N, S, O, P; R1 and R3, identical or different, denote a linear or branched C1-C30 alkyl or alkenyl radical, an aryl radical, at least one of the carbon atoms being able to be replaced by a heteroatom chosen from N, S, O, P; A is a physiologically acceptable anionic counterion such as a halide like chloride or bromide, or a mesylate.

[0098] As regards the meaning of Y, a hydrophilic group is understood to mean a polymeric or non-polymeric water-soluble group.

[0099] By way of example, when not polymers, ethylene glycol, diethylene glycol and propylene glycol may be mentioned.

[0100] When it is a hydrophilic polymer, examples that may be mentioned are polyethers, sulfonated polyesters, sulfonated polyamides, or a mixture of these polymers. Preferably, the hydrophilic compound is a polyether and in particular a poly(ethylene oxide) or poly(propylene oxide).

[0101] The cationic associative polyurethanes of formula (Ia) according to the invention are formed from diisocyanates and various compounds having labile hydrogen functions. The labile hydrogen functions may be alcohol, primary or secondary amine or thiol functions giving, after reaction with the dii-isocyanate functions, respectively polyurethanes, polyureas and polythioureas. The term "polyurethanes" of the present invention encompasses these three types of polymers, namely polyurethanes themselves, polyureas and polythioureas as well as copolymers thereof.

[0102] A first type of compound used in the preparation of the polyurethane of formula (Ia) is a compound comprising at least one amine-functional unit. This compound may be multifunctional, but preferably the compound is difunctional, that is to say that according to a preferred embodiment, this compound comprises two labile hydrogen atoms carried for example by a hydroxyl, primary amine, secondary amine or thiol function. It is also possible to use a mixture of multifunctional and difunctional compounds in which the percentage of multifunctional compounds is low.

[0103] As indicated above, this compound may comprise more than one amine-functional unit. It is then a polymer carrying a repetition of the amine-functional unit.

[0104] This type of compounds can be represented by one of the following formulas: HZ-(P)n-ZH, or HZ-(P')p-ZH, in which Z, P, P', n and p are as defined above.

[0105] Examples that may be mentioned include N-methyldiethanolamine, N-tert-butyldiethanolamine and N-sulfoethyldiethanolamine.

[0106] The second compound used in the preparation of the polyurethane of formula (Ia) is a diisocyanate corresponding to the formula: O=C=N-R4-N=C=O in which R4 is defined above.

[0107] By way of example, mention may be made of methylenediphenyl diisocyanate, methylenecyclohexanediisocyanate, isophoronediisocyanate, toluenediisocyanate, naphthalenediisocyanate, butanediisocyanate, hexanediisocyanate.

[0108] A third compound used in the preparation of the polyurethane of formula (Ia) is a hydrophobic compound intended to form the terminal hydrophobic groups of the polymer of formula (Ia).

[0109] This compound consists of a hydrophobic group and a labile hydrogen function, for example a hydroxyl, primary or secondary amine, or thiol function.

[0110] For example, this compound may be a fatty alcohol, such as stearyl alcohol, dodecyl alcohol, decyl alcohol. When this compound comprises a polymer chain, it may be, for example, alpha-hydroxyl hydrogenated polybutadiene.

[0111] The hydrophobic group of the polyurethane of formula (Ia) can also result from the quaternization reaction of the tertiary amine of the compound comprising at least one tertiary amine unit. Thus, the hydrophobic group is introduced by the quaternizing agent. This quaternizing agent is a compound of type RQ or R'Q, in which R and R' are as defined above and Q denotes a leaving group such as a halide, a sulfate, etc.

[0112] The cationic associative polyurethane may further comprise a hydrophilic sequence. This sequence is provided by a fourth type of compound entering into the preparation of the polymer. This compound can be multifunctional. It is preferably difunctional. We can also have a mixture where the percentage of multifunctional compound is low.

[0113] The labile hydrogen functions are alcohol, primary or secondary amine, or thiol functions. This compound can be a polymer terminated at the ends of the chains by one of these labile hydrogen functions.

[0114] By way of example, when not polymers, ethylene glycol, diethylene glycol and propylene glycol may be mentioned.

[0115] When it is a hydrophilic polymer, examples that may be mentioned are polyethers, sulfonated polyesters, sulfonated polyamides, or a mixture of these polymers. Preferably, the hydrophilic compound is a polyether and in particular a poly(ethylene oxide) or poly(propylene oxide).

[0116] The hydrophilic group denoted Y in formula (Ia) is optional. Indeed, the units with a quaternary or protonated amine function may be sufficient to provide the solubility or hydrodispersibility necessary for this type of polymer in an aqueous solution.

[0117] Although the presence of a hydrophilic Y group is optional, cationic associative polyurethanes comprising such a group are preferred.

[0627] The cosmetic composition according to the invention finds in particular a particularly interesting application in the hair field, in particular for cleaning and / or conditioning the hair. The hair compositions are preferably lotions, masks or conditioners, but can also be presented in the form of a shampoo, particularly a conditioner, which can be rinsed out; or in the form of a pre-shampoo, which can be rinsed out or not before applying a shampoo.

[0628] The cosmetic composition may or may not be rinsed after being applied to keratin materials, in particular to the hair. It is thus possible to optionally rinse, for example with water, after a possible exposure time. Preferably, it is rinsed after a possible exposure time.

[0629] The invention also relates to a process for cosmetic treatment, in particular hair treatment, in particular for washing and / or conditioning keratin fibres, in particular hair, comprising the application to said fibres of a cosmetic composition according to the invention, preferably followed by rinsing, after a possible application time.

[0630] Preferably, it is a hair treatment process, in particular washing and / or conditioning, of sensitized, weakened and / or damaged hair, or even hair loaded with metal ions, in particular copper and / or calcium.

[0631] In particular, it may be a cosmetic treatment process for strengthening hair, particularly sensitized, weakened and / or damaged hair.

[0632] It may also be a process for limiting the loss of shine in hair, particularly when it is sensitized, weakened and / or damaged.

[0633] Said method may also comprise at least two successive application steps, on the hair, in particular sensitized, weakened and / or damaged hair, of a composition as defined above; this is then referred to as a multi-application method.

[0634] The following examples serve to illustrate the invention without, however, being limiting in nature.

[0635] In the following examples, all quantities are indicated, unless otherwise indicated, as a percentage by mass of active ingredient (g% MA) relative to the total weight of the composition. Example 1

[0636] The following compositions A according to the invention and A' comparative were prepared from the ingredients indicated in the tables below (g% MA):

[0637] [Tables 1] Composition A A' CITRIC ACID 1.5 1.5 GLYCINE 2.5 2.5 PEG-150 / DECYL ALCOHOL / SMDI COPOLYMER 0.6 - AMODIMETHICONE 1.1 1.1 BEHENTRIMONIUM CHLORIDE 3 3 HYDROXYPROPYL GUAR 0.15 0.15 CETEARYL ALCOHOL 7 7 CETYL ESTERS 1.5 1.5 ISOPROPYL ALCOHOL 0.7 0.7 GLYCERIN 1 1 POLYQUATERNIUM-37 0.08 0.08 PROPYLENE GLYCOL 0.2 0.2 STEARETH-100 0.25 0.25 Preservatives Qs Qs Water Qs 100% Qs 100%

[0638] Composition A is in the form of a cream and can advantageously be used before shampooing as a pre-shampoo or after shampooing as a hair mask.

[0639] This composition can be used for detangling hair, providing care and strength (body and mass effect) and leads to an improved hair feel, even from root to tip (smooth feel).

[0640] The composition also exhibits reinforcing properties.

[0641] The smoothness of the fiber is evaluated using the extensometry method.

[0642] The compositions were applied to strands of moderately bleached Caucasian hair, previously washed with shampoo and rinsed.

[0643] 0.4 g of composition is then applied per g of hair and rinsed; the locks are then dried in an oven (30 min, 60°C), then the measurement is taken.

[0644] Principle of the method: the method consists of measuring the friction forces of a wick, during its movement (in the root / tip direction) at constant speed, between two pads clamping it at constant compression. This method thus makes it possible to evaluate the “smoothness to the touch” by mimicking the passage of two fingers along a wick of hair.

[0645] The lower the forces required to travel the length of the strand, the smoother the surface condition of the hair.

[0646] We obtain the following results (average over 3 strands):

[0647] [Tables2] Work (mJ) Standard deviation Composition A 55.48 8.68 Composition A' 102.74 17.23

[0648] The lower the measured work, the better the performance of the evaluated formula in terms of smoothness.
