Description

[Technical Field]

[0001] The invention more particularly relates to the cosmetic field of keratinous fibers, in particular for caring for, styling and / or dyeing keratinous fibers, preferably hair.

[0002] The object of the present invention is therefore to propose new treatment methods, in particular cosmetic methods, in which oils functionalized with acetoacetate functional groups are applied to keratin fibers, optionally together with at least one crosslinking agent, which methods are most particularly advantageous in terms of their technical performance, in particular in terms of the persistence of the deposit obtained and the sensory experience provided to the user. [Background technology]

[0003] Cosmetics commonly require the use of one or more film-forming polymers in order to obtain a good deposition of these cosmetics on keratinous materials, especially on keratinous fibers, in particular to meet the requirements detailed below.

[0004] Therefore, in the field of hair care, it is most particularly expected that the deposit formed should have good durability in contact with water, especially rain, in contact with water during showering or even perspiration, and even in contact with sebum. Moreover, this deposit must also be visually appealing, transparent if uncolored, or even glossy. It must also allow the hair to move without changing its appearance, i.e., without cracking and / or flaking. There is also a demand for deposits that can withstand multiple shampoo washings.

[0005] For this purpose, dispersions of nanometer-sized polymer particles are used as film-forming agents in hair care products, more particularly in their organic phase, especially the oily phase.

[0006] However, such compositions of the prior art have had insufficient staying power over time, particularly in terms of styling hold.

[0007] Moreover, in the field of hair care, a new range of products known as "Hair Makeup" has recently been developed, which promise temporary hair dyeing that lasts for one to three shampoo washes.

[0008] They are therefore a particularly attractive option for consumers as an alternative to permanent hair color, provided, of course, that the coloring effect is reliably guaranteed to last even after contact with water and several shampoo washes.

[0009] This need is also met inter alia by the use of effective film formers.

[0010] Thus, French Patent No. FR 2,741,530 proposes the use of a dispersion of film-forming polymer particles, which dispersion contains at least one acidic functional group and at least one pigment dispersed in the continuous phase of the dispersion, for the temporary dyeing of keratin fibers. However, the coloring obtained through this dyeing method has the drawback that it is easily washed off by shampooing.

[0011] Furthermore, French Patent No. FR 2,907,678 proposes to color coat hair with a composition comprising a polysiloxane / polyurea block copolymer and a pigment, but when using such a composition, the coating obtained is not always uniform and the individualization of the hair strands is not always very good.

[0012] Compositions, particularly film-forming cosmetic compositions, are known that comprise at least one fatty phase and at least one copolymer obtained by polymerization with ethylene-based monomers, some of which have specific groups (see, for example, International Publication No. WO2022 / 136104). Nevertheless, such compositions require the presence of a fatty phase, which may limit their application to certain fields. Moreover, these compositions do not necessarily satisfy the naturalness needs of some consumers.

[0013] From EP 1,392,222 it is also known to use cosmetic compositions for the care and / or treatment of keratinous materials, which comprise a supramolecular polymer comprising a polymer backbone and at least two groups capable of forming at least three hydrogen bonds, and from EP 1,435,900 it is also known to use hair compositions, which comprise a supramolecular polymer comprising a polymer backbone and at least two groups capable of forming at least three hydrogen bonds, and a surfactant or hair conditioning agent. However, these two composition options still provide insufficient performance in terms of styling retention over time or in terms of water resistance.

[0014] A method for producing a composition containing a modified polysaccharide is also known from International Publication No. WO 2020 / 026143. Furthermore, US Patent Application Publication No. US 2006 / 0079599 describes a polymer-based tissue adhesive for medical use, which comprises a polyvinyl alcohol polymer having ACAC groups in a hydrogel form together with a polyamine. US Patent Nos. US 3,342,806 and US 3,361,585 describe acetoacetylated starch compounds.

[0015] Moreover, WO 06 / 042169 describes tissue adhesives for medical and veterinary use, which are formed by the reaction of polyhydroxy compounds derived from acetoacetate groups and / or polyamine compounds derived from acetoacetamide groups with amino-functional crosslinking compounds.

[0016] The synthesis of acetoacetate diester triglycerides is also described in International Publication No. WO2016 / 164870.

[0017] Generally, the treatment methods described above do not make it possible to obtain a deposit on keratin fibers that meets all of the above-mentioned requirements (i.e. very good durability, in particular very good durability against shampooing of the hair and / or very good durability against fatty substances, thereby allowing the hair to move without cracking and / or flaking, thereby making it possible to adjust the gloss or invisibility properties, and in the case of hair care uses, providing very satisfactory styling power or color durability).

[0018] Additionally, there is high consumer demand for compositions that have a reduced impact on the environment. Summary of the Invention [Problem to be solved by the invention]

[0019] There is therefore still a need for a treatment method, in particular a cosmetic treatment method, intended for application to keratin fibers, which makes it possible to obtain a deposit that is non-sticky, virtually transfer-resistant, glossy and persistent.

[0020] There also remains a need for treatment methods, especially cosmetic treatment methods, which make it possible to obtain deposits that are resistant to water and fatty substances, especially sebum.

[0021] Additionally, there remains a need for treatments, particularly cosmetic treatments, that provide deposits that have shiny and / or invisibility properties.

[0022] There is also a need for color treatment methods, especially color cosmetic treatment methods, which are intended for application to hair to ensure color durability over time comparable to direct dyeing and which provide deposits with good resistance to water and shampoo washing.

[0023] There is also a need for treatments, especially cosmetic treatments, especially non-coloring treatments, that are intended for application to hair and that provide water-resistant styling properties, especially curl retention.

[0024] The present invention is specifically directed to meeting these needs in whole or in part. [Means for solving the problem]

[0026] According to a preferred embodiment, the treatment method of the invention also comprises a step iii) of applying to the keratinous fibers at least a cosmetic active agent.

[0027] According to a preferred embodiment, the method according to the invention comprises applying to the keratinous fibers i) at least one compound of formula (I) as defined above, its optical or geometric isomers, and / or solvates thereof, such as hydrates, or a composition comprising said compounds, and optionally ii) applying at least one crosslinking agent and / or iii) applying at least one cosmetic active agent.

[0028] When one or more of said cosmetic active agents iii) are present, said one or more cosmetic active agents iii) may be applied simultaneously with i) and / or simultaneously with ii), if ii) is used, or further, when ii) is present, said cosmetic active agent iii) may be applied before i) and / or before ii).

[0031] According to another embodiment, the method comprises applying i), optionally ii), and optionally iii) to dry keratinous fibers.

[0032] The inventors have therefore surprisingly discovered that applying component i), optionally component ii), and optionally component iii) to keratinous fibers makes it possible to obtain a deposit on the keratinous fibers that has good resistance to external attacking factors, such as water, oil, especially food oils, sweat, and / or sebum, and therefore has very good staying power over time. Advantageously, the deposit obtained via the method according to the invention is neither sticky nor transferrable. Applying component i), and optionally component ii) and / or component iii), to keratinous fibers also provides a deposit on the keratinous fibers that has good resistance to shampooing and excellent water resistance.

[0033] The application of component i), and optionally component ii), and / or component iii), to keratinous fibers also provides a shiny deposit.

[0200] The monounsaturated fatty acids are in particular chosen from palmitoleic acid, oleic acid, 9-eicosenoic acid, 11-eicosenoic acid, erucic acid, and nervonic acid.

[0201] The polyunsaturated fatty acids are selected, inter alia, from linoleic acid, α-linolenic acid, γ-linolenic acid, dihomo-γ-linolenic acid, arachidonic acid, eicosapentaenoic acid, docosahexaenoic acid, luminic acid, and hydroxyl monounsaturated fatty acids, in particular 10-hydroxy-cis-12-octadecenoic acid, 10-hydroxy-trans-11-octadecenoic acid, 12-hydroxy-cis-9-octadecenoic acid, 13-hydroxy-cis-9-octadecenoic acid, ricinoleic acid, isoricinoleic acid, and hydroxyl monounsaturated fatty acids selected from polyunsaturated hydroxyl fatty acids, and polyunsaturated fatty acids, in particular densipolic acid, auricolic acid, dimorphecolic acid.

[0203] Second step

[0204] In a second step, all or part of one or more unsaturated groups of one or more AK'2 moieties are converted a) via an epoxidation reaction to give derivatives (III) shown in the scheme described below, e.g., starting compound a1, or b) via a thiol-ene reaction with a (poly)hydroxylated thiol or a thiol bearing one or more acid functional groups to give derivatives (IV) shown in the scheme described below, e.g., compound b3.

[0205] The thiol-ene reaction b) is carried out by the synthesis of (poly)hydroxylated thiols, e.g. of the formula HS-(CH) k This can be carried out using linear hydroxylated thiols with -OH (where k is an integer from 1 to 12, preferably from 1 to 6), such as 2-mercaptoethanol, 3-mercapto-1-propanol, 6-mercapto-1-hexanol, 4-mercapto-1-butanol, or for example branched hydroxylated thiols, preferably containing 1 to 6 carbon atoms, such as 3-mercapto-3-methylbutanol, 3-mercapto-2-butanol, or for example polyhydroxylated thiols, preferably containing 1 to 6 carbon atoms, such as 3-mercapto-1,2-propanediol HS-CH(OH)-CHOH.

[0206] Therefore, the resulting compound (IV) is -S-AK3-(OH) v wherein v is greater than 1, for example 2, if the thiol is hydroxylated; and wherein A K and v are as defined above for compounds of formula (I).

[0207] The third step

[0208] In the third step, all or some of the epoxy groups of the compound of formula (III) are ring-opened with a nucleophilic compound, in particular i) with an alcohol, preferably a C1-C4 alcohol, such as methanol or ethanol or a polyol, to give a compound of formula (IIIi), such as compound b2 shown in the scheme described later in this specification, or ii) with a carboxylic acid, preferably a C1-C6 carboxylic acid, such as lactic acid, pyruvic acid, benzoic acid, glycolic acid or 2,2-bishydroxymethylpropionic acid, more preferably a carboxylic acid substituted with at least one hydroxyl moiety, such as lactic acid, to give a compound of formula (IIIii), such as compound b1 shown in the scheme described later in this specification.

[0209] According to a preferred embodiment, the carboxylic acid ii) is selected from lactic acid, glycolic acid or 2,2-bishydroxymethylpropionic acid (epoxy acid reaction), the reaction being carried out in the presence of a catalyst, such as imidazole, 1-methylimidazole, N,N-dimethylbenzylamine or caffeine.

In particular, certain compounds (where m' is equal to m, p is equal to 0, and Z preferably represents -CH2-CH-CH2-) are commercially available products. When p is equal to 0 and m' is equal to m, the compound is an ester of an optionally hydroxylated unsaturated fatty acid, in particular a triglyceride of castor oil, soybean oil, canola oil, or linseed oil. The synthesis of compounds (Ia) to (Ie) begins with the second step described above.

[0217] For example, starting from unsaturated triglycerides, a thiol-ene reaction can be carried out to give (poly)hydroxyl thiols, e.g., SH—(CH) x OH (where x is preferably an integer from 1 to 4), and then the transesterification reaction (as described in Desroches, M., Caillol, S., Lapinte, V., Auvergne, R. and Boutevin, B.

More preferably, the metal belonging to the group of rare earth metals is selected from cerium and yttrium, and combinations thereof.

[0384] Preferably, the metal M″ belonging to the group of rare earth metals is in the oxidation state +III.

[0385] According to the invention, the compounds of metals belonging to the rare earth metal group are selected from rare earth metal salts and rare earth metal complexes.

[0386] The term "rare earth metal complex" refers to a combination of a metal M'' and one or more ligands.

[0387] Hereinafter, the term "ligand" refers to an ion or molecule having groups that are bonded to the metal M" via ionic and / or coordinate bonds. The same ligand may have multiple groups that are bonded via ionic and / or coordinate bonds.

[0388] Definitions of rare earth metal salts or complexes can be found in Progress in the Science and Technology of the Rare Earths, Volume 1, edited by Leroy Eyring in 1964, published by Macmillan Company and written by F. Gaume-Mahn, page 259 et seq.

[0389] The rare earth metal salts and complexes according to the invention are characterized in that they contain at least one metal atom M'' belonging to the group of rare earth metals, said atom being in the +III oxidation state.

[0390] The metal M" belonging to the group of rare earth metals can then associate via its electron shell with n1 anionic groups which form ionic bonds with M" and / or with n2 groups which form coordinate bonds with M". Groups which form coordinate bonds are, for example, groups with a donor doublet, such as carbonyl or amine groups.

[0391] When n2=0, the compound of the metal belonging to the group of rare earth metals forms a salt in which the metal M″ belonging to the group of rare earth metals is associated with three anionic groups.

[0397] c) The ligand may contain one or more groups that form coordinate bonds and one or more groups that have functional groups that form ionic bonds.

[0398] Thus, the ligand can be a monocarboxylate or polycarboxylate molecule, such as acetate or succinate. In this case, the carboxylate functionality is considered to function as an anionic group through the hydroxyl group of the carboxyl group and as a coordinate bond-forming group through the lone pair of electrons on the oxygen atom of the carbonyl functionality. Thus, the resulting rare earth metal compound is M″(R—(COO) n ) 3 / nThe ligand may have other functional groups, such as hydroxyl or amine, in addition to one or more carboxylates. Thus, the ligand may be composed entirely or partially of hydroxycarboxylic acids or aminocarboxylic acids. Monocarboxylic or polycarboxylic acid compounds with additional functional groups include tartrate, citrate, glycolate, or ethylenediaminetetraacetate (EDTA) ions.

[0399] The ligand may have a non-localized anionic charge, such as acetylacetonate. The rare earth metal compound is M"(acetylacetonate) or M"(acetylacetonate)3·7H2O, where each acetonate is bonded to the metal M" via its two carbonyl functionalities, one of which functions as the anionic group and the other as the coordinative bonding group.

[0547] Example

[0548] Methods and Measurements

[0549] Application to hair

[0550] The hair dye evaluation protocol is described in detail below.

[0551] The evaluation is carried out according to three different protocols: 1-step, 2-step, or 3-step. Each protocol is carried out using natural hair tresses with 90% white hair.

[0552] a) One-step protocol

[0553] The compound of formula (I) having acetoacetate functionality and the crosslinker are mixed together prior to application, and the system remains fluid long enough to allow application to a substrate.

[0554] The composition is applied to tresses of dry, natural hair containing 90% white hair at a ratio of 1 gram of composition per gram of tress.

[0555] The hair tresses are left at room temperature for 5 minutes.

[0556] The hair strands are then combed and dried with a hairdryer for 3 minutes.

[0557] The tresses are left at room temperature at 80% relative humidity for 18 hours. The hair is dyed evenly and deeply.

[0558] b) Two-step protocol

[0559] A first composition, called the base coat, is applied to a tress of dry natural hair containing 90% white hair at a ratio of 0.5 g per gram of tress. The tress is then combed. This deposit is applied to the keratinous material and then left at room temperature (25°C) for 30 minutes.

[0560] After this first gesture, a second composition, called the top coat, is applied at a rate of 0.5 g per gram of lock.

[0561] After application, the locks are combed and dried with a hairdryer.

[0562] The locks are left at room temperature in a fume cupboard for 24 hours. The hair is dyed evenly and deeply.

[0563] The hair tresses thus colored are then subjected to a repeated shampoo wash test in order to evaluate the fastness (durability) of the color obtained with respect to shampoo wash, according to the shampoo wash protocol described below.

[0564] c) Three-step protocol

[0565] A first composition containing pigment carried in a cosmetic solvent is applied to a tress of dry natural hair containing 90% white hair at a ratio of 0.5 g of composition per gram of tress and then left to stand for 1 minute at room temperature (25°C).

[0566] A second composition, called base coat, is applied to the colored locks at a ratio of 0.5 g per gram of lock, which is then combed and left to stand for 30 minutes at room temperature (25°C).

[0567] After this second gesture, a third composition, called the top coat, is applied at a rate of 0.5 g per gram of lock.

[0568] After application, the locks are combed and dried with a hair dryer.

[0569] The locks are left at room temperature in a fume cupboard for 24 hours. The hair is dyed evenly and deeply.

[0570] The hair tresses thus colored are then subjected to a repeated shampoo wash test in order to evaluate the fastness (durability) of the color obtained with respect to shampoo wash, according to the shampoo wash protocol described below.

[0571] Shampoo Cleansing Protocol

[0572] The dyed locks of hair are combed, moistened with water at 35°C, and then passed through the fingers five times for five seconds each time. The locks are then squeezed dry between two fingers.

[0573] A standard shampoo (Garnier Ultra Doux) is applied evenly to the dyed tresses at a ratio of 0.4g per gram of tress, whereupon the tresses are gently massaged along their length from root to tip for 15 seconds (6 times).

[0574] The tuft of hair is then placed on the watch glass and left for 1 minute.

[0575] The lock of hair is then rinsed with water (15 times) while passing the lock between the fingers.The lock of hair is then squeezed dry between two fingers before the next shampoo wash.

[0576] Once the multiple shampoo wash test is completed, the hair tresses are combed and dried with a hair dryer.

[0577] Persistence Protocol

[0578] The color durability of the bundles was evaluated in the CIE L*a*b* system with a Minolta Spectrophotometer CM3600A color difference meter (illuminant D65, angle 10°, including specular reflection component).

[0579] In this L*a*b* system, L* represents the color intensity, a* represents the green / red color axis, and b* represents the blue / yellow color axis.

[0580] The durability of the color was evaluated by the color difference ΔE between the dyed tresses before shampooing, 24 hours after the last application of the composition of formula (I) in the case of the 1-gesture protocol 1, or 24 hours after the application of the "top coat" in the case of the 2-gesture protocol and the 3-gesture protocol, and the dyed tresses after shampooing, after 3 or 5 shampooings according to the protocols described above.

[0581] The lower the ΔE value, the more durable the color is after shampooing.

[0582] ΔE is calculated according to the following formula:

number

[0583] In this formula, L*a*b* represents the measurement after dyeing and shampooing the hair, and L0*a0*b0* represents the measurement after dyeing the hair but before shampooing.

[0584] Styling Application: Styling Evaluation Protocol

[0585] The styling evaluation protocol is detailed below.

[0586] 2 g of a solution containing the formulation described below is sprayed onto a tress (90% Natural White (NW) hair, 20.5 cm long). The tress is weighed before and after application. Approximately 0.5 g of the composition is effectively deposited on the tress.

[0587] The bundle is wrapped around a brush (approximately 2 cm in diameter and 3 cm in length) and left at room temperature (25°C).

[0588] After 24 hours, the tress is removed from the brush and hung up. The length of the tress is measured. After 24 hours of hanging, the length of the tress is measured again.

[0589] A comparison of curl retention is made between compositions according to the invention and comparative compositions.
