Description

Title of the invention: A hair coloring process comprising the application of a (poly)carbodiimide compound, a silicone acrylic copolymer, and a coloring agent

[0001] The present invention relates to a hair coloring process comprising the application to the hair of at least one composition C comprising one or more (poly)carbodiimide compounds (i); one or more silicone acrylic copolymers (ii); and at least one coloring agent (iii), the compounds (i), (ii) and / or (iii) being packaged together or separately in one or more aerosol devices in the presence of at least one propellant. technical field

[0002] In the field of hair keratin fiber coloring, particularly human hair, it is already known to color hair keratin fibers by different techniques from direct dyes or pigments for non-permanent colorings or from dye precursors for permanent colorings.

[0003] There are essentially three types of hair coloring processes: a) so-called permanent coloring which has the function of bringing about a significant change in the natural color and which uses oxidation dyes which penetrate the hair fiber and form the dye by a process of oxidative condensation; b) non-permanent, semi-permanent or direct coloring, which does not implement the oxidative condensation process and resists 4 or 5 shampoos; consists of dyeing the keratin fibers with dyeing compositions containing direct dyes; c) Temporary hair coloring, which results in a change to the natural hair color that lasts from one shampoo to the next and is used to enhance or correct an existing shade. It can also be considered a "makeup" procedure.

[0004] For this latter type of coloring, it is known to use colored polymers formed by grafting one or more dyes of azo, triphenyl-methanic, azinic, indoamine, or anthraquinone nature onto a polymer chain. These colored polymers are not entirely satisfactory, particularly with regard to the homogeneity of the color obtained and its resistance, not to mention the problems related to their manufacture and especially their reproducibility.

[0005] Another coloring method involves using pigments. Indeed, the use of pigment on the surface of keratin fibers generally makes it possible to obtain visible colors on dark hair since the pigment on the surface masks the natural color of the fiber.

[0006] However, temporary hair coloring compositions can lead to cosmetic properties that do not give complete satisfaction, more particularly hair conditioning properties, especially in terms of detangling, suppleness and smooth feel of the hair.

[0007] There therefore remains a need for a hair coloring process which has the advantage of obtaining a homogeneous colored coating on the hair, and which allows for improved hair conditioning properties, particularly in terms of detangling, suppleness and smooth feel of the hair.

[0008] Thus, the object of the present invention is to develop a hair coloring process that has the advantage of obtaining a homogeneous colored coating and providing improved hair conditioning properties, particularly in terms of detangling, suppleness, and a smooth feel.

[0010] Thanks to the hair coloring process according to the invention, colored coatings are obtained on the hair, resulting in visible coloring on all hair types and excellent hair conditioning properties, particularly in terms of detangling, suppleness, and a smooth feel. In particular, it allows for a homogeneous deposit.

[0011] In addition, the colour coating on the hair is obtained quickly and easily.

[0096] The pigments that can be used are chosen in particular from among the organic and / or mineral pigments known in the art, in particular those described in Kirk-Othmer's Encyclopedia of Chemical Technology and in Ullmann's Encyclopedia of Industrial Chemistry.

[0097] They may be natural, of natural origin, or not.

[0098] These pigments may be in the form of a powder or pigment paste. They may be coated or uncoated.

[0099] Pigments can, for example, be chosen from mineral pigments, organic pigments, lacquers, special effect pigments such as mother-of-pearl or glitter, and mixtures thereof.

[0100] The pigment may be a mineral pigment. By mineral pigment, we mean any pigment that meets the definition in the Ullmann Encyclopedia in the chapter on inorganic pigments. Examples of mineral pigments useful in the present invention include iron or chromium oxides, manganese violet, ultramarine blue, chromium hydrate, ferric blue, and titanium dioxide.

[0101] The pigment may be an organic pigment. By "organic pigment" is meant any pigment that meets the definition in the Ullmann encyclopedia in the chapter on organic pigment.

[0102] The organic pigment may in particular be selected from the following compounds: nitroso, nitro, azo, xanthene, pyrene, quinoline, quinoline, anthraquinone, triphenylmethane, fluorane, phthalocyanine, metal complex type, isoindolinone, isoindoline, qui-nacridone, perinone, perylene, diketopyrrolopyrrole, indigo, thioindigo, dioxazine, triphenylmethane, quinophthalone.

[0105] The pigments according to the invention can also be in the form of composite pigments as described in patent EP 1 184 426. These composite pigments can be composed in particular of particles comprising an inorganic core, at least one binder ensuring the fixation of organic pigments on the core, and at least one organic pigment covering at least partially the core.

[0106] The organic pigment can also be a lacquer. By lacquer, we mean colorants adsorbed onto insoluble particles, the whole thus obtained remaining insoluble during use.

[0107] The inorganic substrates on which the dyes are adsorbed are, for example, alumina, silica, calcium sodium borosilicate or calcium aluminium borosilicate, and aluminium.

[0108] Among the colorants, carminic acid may be mentioned. Other colorants known by the following names may also be mentioned: D&C Red 21 (CI 45380), D&C Orange 5 (CI 45370), D&C Red 27 (CI 45410), D&C Orange 10 (CI 45425), D&C Red 3 (CI 45430), D&C Red 4 (CI 15510), D&C Red 33 (CI 17200), D&C Yellow 5 (CI 19140), D&C Yellow 6 (CI 15985), D&C Green (CI 61570), D&C Yellow 1 O (CI 77 002), D & C Green 3 (CI 42 053), D & C Blue 1 (CI 42 090).

[0109] As examples of lacquers, we can cite the product known under the following name: D & C Red 7 (CI 15 850 :1).

[0110] The pigment can also be a special effects pigment. Special effects pigments are defined as pigments that generally create a non-uniform and changing colored appearance (characterized by a certain shade, vibrancy, and clarity) depending on the viewing conditions (light, temperature, viewing angles, etc.). They are thus distinct from colored pigments that provide a uniform opaque, semi-transparent, or conventionally transparent tint.

[0111] There are several types of special effect pigments, those with a low refractive index such as fluorescent or photochromic pigments, and those with a higher refractive index such as mother-of-pearl, interference pigments or glitter.

[0112] Examples of special effect pigments include pearlescent pigments such as titanium-coated mica or bismuth oxychloride, colored pearlescent pigments such as titanium-coated mica with iron oxides, iron oxide-coated mica, titanium-coated mica, particularly with ferric blue or chromium oxide, titanium-coated mica with an organic pigment as defined above, and bismuth oxychloride-based pearlescent pigments. Examples of pearlescent pigments include Cellini pearlescent pigments marketed by BASF (Mica-TiO2-lake), Prestige pearlescent pigments marketed by Eckart (Mica-TiO2), Prestige Bronze marketed by Eckart (Mica-Fe2O3), and Colorona marketed by Merck (Mica-TiO2-Fe2O3).

[0113] We can also mention gold-colored mother-of-pearl, notably marketed by BASF under the names Brilliant Gold 212G (Timica), Gold 222C (Cloisonne), Sparkle Gold (Timica), Gold 4504 (Chromalite) and Monarch Gold 233X (Cloisonne); bronze mother-of-pearl, notably marketed by MERCK under the names Bronze Fine (17384) (Colorona) and Bronze (17353) (Colorona) and by BASF under the name Super Bronze (Cloisonne); orange mother-of-pearl, notably marketed by BASF under the names Orange 363C (Cloisonne) and Orange MCR 101 (Cosmica) and by MERCK under the names Passion Orange (Colorona) and Matte Orange (17449) (Microna); brown-tinted mother-of-pearl, notably marketed by BASF under the names Nu-antique copper 340XB (Cloisonne) and Brown CL4509 (Chromalite); copper-tinted mother-of-pearl, notably marketed by BASF under the name Copper 340A (Timica);red-tinted mother-of-pearl, notably marketed by the company MERCK under the name Sienna fine (17386) (Colorona); yellow-tinted mother-of-pearl, notably marketed by the company BASF under the name; Yellow (4502) (Chromalite); red-tinted pearlescent pigments with a gold sheen, notably marketed by BASF under the name Sunstone G012 (Gemtone); pink pearlescent pigments, notably marketed by BASF under the name Tan opale G005 (Gemtone); black pearlescent pigments with a gold sheen, notably marketed by BASF under the name Nu antique bronze 240 AB (Timica); blue pearlescent pigments, notably marketed by MERCK under the name Matte blue (17433) (Microna); white pearlescent pigments with a silver sheen, notably marketed by MERCK under the name Xirona Silver; and orange-pink-green-gold pearlescent pigments, notably marketed by MERCK under the name Indian summer (Xirona), and their mixtures.

[0114] As further examples of nacres, we can also mention particles comprising a borosilicate substrate coated with titanium oxide.

[0115] Particles with a glass substrate coated with titanium oxide are notably sold under the name METASHINE MC1080RY by the company TOYAL.

[0116] Finally, examples of mother-of-pearl include polyethylene terephthalate flakes, particularly those marketed by Meadowbrook Inventions under the name Silver IP 0.004X0.004 (silver flakes). Multilayer pigments based on synthetic substrates such as alumina, silica, calcium sodium borosilicate or calcium aluminum borosilicate, and aluminum can also be considered.

[0117] Special effect pigments may also be selected from reflective particles, that is to say, particles whose size, structure, including the thickness of the layer(s) that constitute them and their physical and chemical nature, and surface condition, enable them to reflect incident light. This reflection may, where appropriate, have sufficient intensity to create, on the surface of the composition or mixture, when applied to the makeup support, highlights visible to the naked eye, that is to say, brighter points that contrast with their surroundings by appearing to shine.

[0118] The reflective particles can be selected so as not to significantly alter the coloring effect generated by the coloring agents associated with them, and more particularly so as to optimize this effect in terms of color rendering. They can, in particular, have a yellow, pink, red, bronze, orange, brown, gold and / or copper color or reflection.

[0119] These particles can have various shapes, including being platelet-shaped or globular, particularly spherical.

[0120] Reflective particles, whatever their shape, may or may not have a multilayer structure and, in the case of a multilayer structure, for example at least one layer of uniform thickness, in particular of a reflective material.

[0121] When reflective particles do not have a multilayer structure, they can be composed, for example, of metal oxides, in particular titanium or iron oxides obtained by synthesis.

[0122] When reflective particles have a multilayer structure, they may, for example, comprise a natural or synthetic substrate, in particular a synthetic substrate at least partially coated by at least one layer of a reflective material, in particular at least one metal or metallic material. The substrate may be monomaterial, multimaterial, organic and / or inorganic.

[0123] More particularly, it may be selected from glasses, ceramics, graphite, metal oxides, aluminas, silicas, silicates, in particular aluminosilicates and borosilicates, synthetic mica and their mixtures, this list not being exhaustive.

[0124] The reflective material may include a layer of metal or a metallic material.

[0125] Reflective particles are described in particular in documents JP-A-09188830, JP-A-10158450, JP-A-10158541, JP-A-07258460 and JP-A-05017710.

[0126] As further examples of reflective particles comprising a mineral substrate coated with a layer of metal, one can also mention particles comprising a borosilicate substrate coated with silver.

[0127] Silver-coated glass substrate particles in the form of wafers are sold under the name MICROGLASS METASHINE REFSX 2025 PS by the company TOYAL. Nickel / chromium / molybdenum alloy-coated glass substrate particles are sold under the names CRYSTAL STAR GF 550, GF 2525 by the same company.

[0128] Particles comprising a metallic substrate such as silver, aluminum, iron, chromium, nickel, molybdenum, gold, copper, zinc, tin, magnesium, steel, bronze, titanium may also be used, said substrate being coated with at least one layer of at least one metallic oxide such as titanium oxide, aluminum oxide, iron oxide, cerium oxide, chromium oxide, silicon oxides and mixtures thereof.

[0129] An example can be cited as aluminium, bronze or copper powders coated with SiO2 marketed under the name VISIONAIRE by the company ECKART.

[0130] We can also mention non-substrate-fixed interference pigments such as liquid crystals (Wacker's Helicones HC), interference holographic glitter (Spectratek's Geometry Pigments or Spectra f / x). Special effect pigments also include fluorescent pigments, whether substances that fluoresce in daylight or produce ultraviolet fluorescence, the phosphorescent pigments, photochromic pigments, thermo-chromic pigments and quantum dots, marketed for example by the company Quantum Dots Corporation.

[0131] The variety of pigments that can be used in the present invention makes it possible to obtain a rich palette of colors, as well as particular optical effects such as metallic, interference effects.

[0132] The size of the pigment used in the composition according to the present invention is generally between 10 nm and 200 µm, preferably between 20 nm and 80 µm, and more preferably between 30 nm and 50 µm.

[0133] The pigments can be dispersed within the composition by means of a dispersing agent.

[0134] The dispersing agent serves to protect the dispersed particles from agglomeration or flocculation. This dispersing agent may be a surfactant, an oligomer, a polymer, or a mixture of several of these, possessing one or more functionalities with a strong affinity for the surface of the particles to be dispersed. In particular, they may adhere physically or chemically to the surface of the pigments. These dispersants also have at least one functional group that is compatible with or soluble in the continuous medium.In particular, esters of 12-hydroxystearic acid are used, especially C8 to C20 fatty acids and polyols such as glycerol and diglycerin, such as poly(12-hydroxystearic acid) stearate with a molecular weight of approximately 750g / mol, such as that sold under the name Solsperse 21 000 by Avecia, polyglyceryl-2 dipolyhydroxystearate (name CTFA) sold under the reference Dehymyls PGPH by Henkel, or polyhydroxystearic acid such as that sold under the reference Arlacel P100 by Uniqema and their mixtures.

[0135] As another dispersant that can be used in the compositions of the invention, we can mention quaternary ammonium derivatives of polycondensed fatty acids such as Solsperse 17 000 sold by Avecia, poly dimethylsiloxane / oxypropylene mixtures such as those sold by Dow Corning under the references DC2-5185, DC2-5225 C.

[0136] The pigments used in the composition can be surface treated with an organic agent.

[0137] Thus, the surface-treated pigments useful within the scope of the invention are pigments that have undergone, totally or partially, a surface treatment of a chemical, electronic, electrochemical, mechanochemical, or mechanical nature with an organic agent such as those described in particular in Cosmetics and Toiletries, February 1990, Vol. 105, pp. 53-64, before being dispersed in the composition according to the invention. These organic agents may, for example, be chosen from waxes, such as carnauba wax and beeswax; fatty acids, fatty alcohols and their derivatives, such as stearic acid, hydroxystearic acid, Stearyl alcohol, hydroxystearyl alcohol, lauric acid and their derivatives; anionic surfactants; lecithins; sodium, potassium, magnesium, iron, titanium, zinc or aluminium salts of fatty acids, for example aluminium stearate or laurate; metal alkoxides; polyethylene; (meth)acrylic polymers, for example polymethyl methacrylates; polymers and copolymers containing acrylate motifs; alkanoamines; silicone compounds, for example silicones, in particular polydimethylsiloxanes; fluorinated organic compounds, for example perfluoroalkyl ethers; fluorosilicone compounds.

[0138] The surface-treated pigments useful in the composition may also have been treated by a mixture of these compounds and / or have undergone several surface treatments.

[0139] The surface-treated pigments useful in the context of the present invention can be prepared using surface treatment techniques well known to those skilled in the art or found as such in the commercial market.

[0140] Preferably, the surface-treated pigments are covered by an organic layer.

[0141] The organic agent with which the pigments are treated can be deposited on the pigments by solvent evaporation, chemical reaction between the molecules of the surfactant or creation of a covalent bond between the surfactant and the pigments.

[0142] Surface treatment can thus be achieved, for example, by a chemical reaction of a surfactant with the surface of the pigments and the creation of a covalent bond between the surfactant and the pigments or fillers. This method is described in particular in US patent 4,578,266.

[0318] Each of the compositions Cl and C2 is applied with the finger to strands of light brown hair (level 4), at a rate of 0.8g of composition per gram of strand. The hair strands are dried with a hairdryer on medium heat while combing them.

[0319] The hair strands are then stored at ambient temperature and humidity for 24 hours.

[0320] The properties in terms of detangling and smooth feel were then evaluated. Evaluation of the detangling process

[0321] Detangling was carried out on the colored strands as previously prepared, without prior detangling.

[0322] It is assessed using a fine-toothed comb, in a single movement: the comb slides through the strand and when it gets stuck, the detangled length is measured.

[0323] This evaluation is carried out on a single strand per composition.

[0324] The results are summarized in Table 5 below.

[0325] [Tables5] Method using composition Cl (invention) C2 (comparative) Length of untangled strand (cm) 20 15

[0326] It is clear that the strand of hair treated with the process according to the invention has a greater length of untangled strand than that of the strand of hair treated with a comparative process.

[0327] Thus, the colored coating obtained with the process according to the invention exhibits improved detangling

[0328] Evaluation of the smoothness and suppleness of the hair:

[0329] Performance in terms of smooth touch and suppleness on strands of The previously prepared colored hair was evaluated by 6 experts.

[0330] Performance was assessed in a blind test in which each of the 6 experts assigned a score in the range from 0 (very poor level of smoothness / very poor flexibility) to 5 (very good level of smoothness / very good flexibility) to each of the strands of hair.

[0331] To assess the smooth touch property, the expert grasps the strand of hair between their thumb and forefinger and slides their fingers along the strand from the top to the tips. They assess whether the hair has any roughness or catches on the fingers.

[0332] To evaluate the flexibility property, the expert takes the lock of hair and tries to bend it in the hollow of his palm by squeezing it 3 times, for 1 second per squeezing.

[0333] The more easily the hair can be bent and curved, the better its suppleness.

[0334] The results are summarized in Tables 6 and 7 below.

[0335] [Tableauxô] Smooth touch property Cl (invention) C2 (comparative) Average 3.2 2.5

[0336] [Tables?] Flexibility property Cl (invention) C2 (comparative) Average 3.2 2.3

[0337] It is clear that the hair strands treated with the process according to the invention have a significantly smoother feel and better suppleness than the smooth feel and suppleness of the hair strands treated with a comparative process.

[0338] Thus, the coloured coating obtained with the process according to the invention has an improved smooth feel and improved flexibility.
