Description

Title of the invention: Hair coloring composition comprising at least one (poly)carbodiimide compound and at least one non-carboxylic anionic thickening agent

[0001] The present invention relates to a hair coloring composition comprising at least one (poly)carbodiimide compound, and at least one non-carboxylic anionic thickening agent.

[0002] The present invention also relates to a hair coloring process comprising the application of said composition and a hair coloring device. technical field

[0003] 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.

[0004] There are essentially three types of hair coloring processes:

[0005] 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;

[0006] 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;

[0007] c) Temporary hair coloring that results in a change to the natural hair color that lasts from one shampoo to the next and serves to enhance or correct a previously achieved shade. It can also be considered a "makeup" process.

[0008] 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.

[0009] 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. However, the colors obtained by this coloring method have the disadvantage of having low resistance to shampoos as well as to external agents such as sebum, perspiration, brushing and / or friction.

[0010] In addition, temporary hair coloring compositions may also have qualities of use which do not give complete satisfaction, in particular in terms of texture, ease and / or homogeneity of distribution on the hair.

[0011] There therefore remains a need for a hair coloring composition which has the advantage of obtaining a homogeneous and smooth colored coating on the hair, while forming a coating that is resistant to shampoos and to the various aggressions that hair can undergo such as brushing and / or rubbing without damaging the hair, and which has good stability over time, as well as good qualities of use.

[0012] Thus, the aim of the present invention is to develop a hair coloring composition which has the advantage of obtaining a homogeneous and smooth colored coating on the hair, while forming a coating that is resistant to shampoos and to the various aggressions that the hair may undergo such as brushing and / or rubbing without damaging the hair, and which has good stability over time and good qualities of use, in particular in terms of texture, ease and / or homogeneity of distribution on the hair. Description of the invention

[0013] The present invention therefore relates to a hair coloring composition C comprising: - at least one (poly)carbodiimide compound, and;

[0014] - at least one non-carboxylic anionic thickening agent.

[0015] The present invention also relates to a hair coloring process, such as for hair, comprising the application to the hair keratin fibers of at least one composition C according to the invention.

[0016] The present invention also relates to a hair coloring device, comprising at least one compartment containing:

[0017] - in a first compartment (El), a composition C according to the invention; and

[0018] - optionally in a second compartment (E2), a composition D such that defined below.

[0019] Thanks to the coloring composition C according to the invention, colored coatings are obtained on the hair, providing visible color on all hair types that is permanent after shampooing, while preserving the physical qualities of the hair's keratin fibers. Such a coating can be resistant to external aggressions. It protects against external factors that hair can experience, such as blow-drying and perspiration. In particular, it helps to achieve a smooth and even finish.

[0020] Furthermore, composition C exhibits good stability over time, particularly after periods of storage at room temperature or at temperatures up to 55°C.

[0021] Furthermore, the composition according to the invention exhibits good performance qualities, particularly in terms of texture, ease and even distribution on the hair, minimizing potential dripping problems. Advantageously, the composition according to the invention has a gel-like texture.

[0022] For the purposes of this invention, "residual color after shampooing" means that the color obtained persists after one shampoo, preferably after 3 shampoos, more preferably after 5 shampoos.

[0023] The expression "at least one" means one or more.

Non-carboxylic anionic thickening agent

[0192] Composition C further comprises at least one non-carboxylic anionic thickening agent.

[0193] For the purposes of the present invention, "non-carboxylic agent" means an agent that does not include a carboxylic acid (-COOH) or carboxylate (-COO) function.

[0194] For the purposes of this invention, a thickening agent is defined as a compound which increases the viscosity of a composition into which it is introduced at a concentration of 0.05% by weight relative to the total weight of the composition, by at least 20 cps, preferably at least 50 cps, at room temperature (25°C), at atmospheric pressure and at a shear rate of 1 s⁻¹ (the viscosity can be measured using a cone / plate viscometer, Haake R600 rheometer or similar).

[0195] Preferably, the non-carboxylic anionic thickening agent(s) are chosen from among non-carboxylic anionic polymers, more preferentially from among anionic polymers with sulfonic group(s).

[0196] For the purposes of this invention, anionic polymer means a polymer comprising one or more anionic or anionizable groups and not comprising any cationic or cationizable group.

[0197] Advantageously, the non-carboxylic anionic thickening agent(s) are chosen from anionic polymers comprising at least one monomer with ethylenic unsaturation and a sulfonic group, in free form or partially or totally neutralized.

[0198] These polymers can be crosslinked or non-crosslinked. They are preferably crosslinked.

[0199] These polymers may be associative or non-associative, preferably non-associative.

[0200] It is recalled that "associative polymers" are polymers capable, in an aqueous medium, of reversibly associating with each other or with other molecules.

[0201] Their chemical structure includes more particularly at least one hydrophilic zone and at least one hydrophobic zone.

[0202] By "hydrophobic group" is meant a radical or hydrocarbon chain polymer, saturated or unsaturated, linear or branched, comprising at least 8 carbon atoms, preferably 10 to 30 carbon atoms, in particular 12 to 30 carbon atoms and more preferably 18 to 30 carbon atoms.

[0203] Preferably, the hydrocarbon group is derived from a monofunctional compound. For example, the hydrophobic group may be derived from a fatty alcohol such as stearyl alcohol, dodecyl alcohol, or decyl alcohol. It may also refer to a hydrocarbon polymer such as polybutadiene.

[0204] Monomers with ethylenic unsaturation and a sulfonic group are selected in particular from vinylsulfonic acid, styrenesulfonic acid, (meth)acrylamido(Ci-C22)alkylsulfonic acids, N-(CrC22)alkyl(meth)acrylamido-(Ci-C22)alkylsulfonic acids such as undecyl-acrylamido-methane-sulfonic acid and their partially or totally neutralized forms.

[0206] In particular, 2-acrylamido-2-methylpropanesulfonic acid (AMPS) and its partially or totally neutralized forms will be used.

These polymers may also contain other ethylenically unsaturated hydrophilic monomers selected, for example, from (meth)acrylic acid derivatives, such as their esters obtained with monoalcohols or mono- or polyalkylene glycols, (meth)acrylamides, vinylpyrrolidone, or mixtures of these compounds.

[0210] Preferred polymers of this family are chosen from among associative copolymers of AMPS and at least one hydrophobic monomer with ethylenic unsaturation.

[0211] These same copolymers may further contain one or more ethylenically unsaturated monomers without a fatty chain such as (meth)acrylic acid derivatives, in particular their esters obtained with monoalcohols or mono- or poly-alkylene glycols, (meth)acrylamides, vinylpyrrolidone, or mixtures of these compounds.

[0335] The pigments that can be used are in particular chosen 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.

[0336] They may be natural, of natural origin, or not.

[0337] These pigments may be in the form of powder or pigment paste. They may be coated or uncoated.

[0338] 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.

[0339] 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 oxide.

[0340] 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.

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.

[0354] 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.

[0355] The inorganic substrates on which the dyes are adsorbed are, for example, alumina, silica, calcium sodium borosilicate or calcium aluminium borosilicate, and aluminium.

[0356] Among the colorants, we can mention carminic acid. We can also mention the colorants known under the following names: D & C Red 21 (CI 45 380), D & C Orange 5 (CI 45 370), D & C Red 27 (CI 45 410), D & C Orange 10 (CI 45 425), D & C Red 3 (CI 45 430), D & C Red 4 (CI 15 510), D & C Red 33 (CI 17 200), D & C Yellow 5 (CI 19 140), D & C Yellow 6 (CI 15 985), D & C Green (CI 61 570), D & C Yellow 1 O (CI 77 002), D & C Green 3 (CI 42 053), D & C Blue 1 (CI 42 090).

[0357] As examples of lacquers, we can cite the product known under the following name: D & C Red 7 (CI 15 850 :1).

[0358] 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.

[0359] 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.

[0360] 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 pearlescent pigments marketed by Eckart (Mica-Fe2O3), and Colorona pearlescent pigments marketed by Merck (Mica-TiO2-Fe2O3).

[0361] 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 MERCK under the name Sienna fine (17386) (Colorona); yellow-tinted mother-of-pearl, notably marketed by BASF under the name Yellow (4502) (Chromalite); red-tinted mother-of-pearl with a gold sheen, notably marketed by BASF under the name Sunstone G012 (Gemtone); pink mother-of-pearl, notably marketed by BASF under the name Tan opale G005 (Gemtone);black mother-of-pearl with a gold sheen, notably marketed by BASF under the name Nu antique bronze 240 AB (Timica); blue mother-of-pearl, notably marketed by MERCK under the name Matte blue (17433) (Microna); white mother-of-pearl with a silver sheen, notably marketed by MERCK under the name Xirona Silver; and orange-pink-green-gold mother-of-pearl, notably marketed by MERCK under the name Indian summer (Xirona), and their mixtures.

[0362] As further examples of nacres, we can also mention particles comprising a borosilicate substrate coated with titanium oxide.

[0363] Particles with a glass substrate coated with titanium oxide are notably sold under the name METASHINE MC1080RY by the company TOYAL.

[0364] 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.

[0365] 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.

[0366] 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 may, in particular, have a yellow, pink, red, bronze, orange, brown, gold and / or copper color or reflection.

[0367] These particles can have various shapes, including being platelet-shaped or globular, particularly spherical.

[0368] 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.

[0369] 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.

[0370] 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.

[0371] More specifically, it can be selected from glasses, ceramics, graphite, metal oxides, aluminas, silicas, silicates, in particular alumino- silicates and borosilicates, synthetic mica and their mixtures, this list is not exhaustive.

[0372] The reflective material may include a layer of metal or a metallic material.

[0373] Reflective particles are described in particular in documents JP-A-09188830, JP-A-10158450, JP-A-10158541, JP-A-07258460 and JP-A-05017710.

[0374] 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.

[0375] 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.

[0376] 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.

[0377] An example can be cited as aluminium, bronze or copper powders coated with SiO2 marketed under the name VISIONAIRE by the company ECKART.

[0378] Other examples include non-substrate interference pigments such as liquid crystals (Wacker's Helicones HC) and interference holographic glitter (Spectratek's Geometry Pigments or Spectra f / x). Special effect pigments also include fluorescent pigments, whether daylight fluorescent or ultraviolet fluorescent, phosphorescent pigments, photochromic pigments, thermochromic pigments, and quantum dots, marketed, for example, by Quantum Dots Corporation.

[0379] 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.

[0380] 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.

[0381] The pigments can be dispersed in the composition by means of a dispersing agent.

[0382] 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 bind 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, 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.

[0383] 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.

[0384] The pigments used in the composition can be surface treated with an organic agent.

[0385] Thus the pigments previously treated on the surface useful within the framework of the invention are pigments which have undergone totally or partially a surface treatment of a chemical, electronic, electro-chemical, mechano-chemical or mechanical nature, with an organic agent such as those described in particular in Cosmetics and Toiletries, February 1990, Vol. 105, p. 53-64 before being dispersed in the composition according to the invention.These organic agents may be chosen, for example, 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 aluminum salts of fatty acids, for example aluminum stearate or laurate; metal alkoxides; polyethylene; (meth)acrylic polymers, for example polymethyl methacrylates; polymers and copolymers containing acrylate units; alkanoamines; silicone compounds, for example silicones, in particular polydimethylsiloxanes; fluorinated organic compounds, for example perfluoroalkyl ethers; Fluoro-silicon compounds.

[0386] Surface-treated pigments useful in the composition may also have been treated by a mixture of these compounds and / or having undergone several surface treatments.

[0387] The surface-treated pigments useful in the context of the present invention can be prepared according to surface treatment techniques well known to those skilled in the art or found as such in the commercial market.

[0388] Preferably, the surface-treated pigments are covered by an organic layer.

[0389] 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.

[0390] 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.

[0391] Preferably, an organic agent covalently linked to the pigments will be used.

[0392] The surface treatment agent may represent from 0.1 to 50% by weight of the total weight of the pigment treated on the surface, preferably from 0.5 to 30% by weight, and even more preferably from 1 to 20% by weight of the total weight of the pigment treated on the surface.

[0393] Preferably, the surface treatments of the pigments are chosen from the following treatments:

[0394] - a PEG-Silicone treatment such as the AQ surface treatment marketed by LCW;

[0395] - a Methicone treatment such as the SI surface treatment marketed by LCW;

[0396] - a Dimethicone treatment such as the Covasil 3.05 com surface treatment marketed by LCW;

[0407] - an Acrylate copolymer treatment such as the APD surface treatment marketed by Daito;

[0828] (6) sold by the company ROHM and HAAS under the trade name ACULYN 22® (methacrylic acid / ethyl acrylate / oxyalkylated stearyl methacrylate terpolymer with 30% active ingredient)

[0829] The appearance of the compositions is observed at the end of their preparation, at T0.

[0830] Compositions Al and A2 are in the form of a fluid and smooth gel.

[0831] Composition A3 is presented as a thick gel. Composition A4 is presented as a soft, smooth, and glossy gel.

[0832] Compositions B1 and B2 are in the form of a coloured, viscous and stringy gel.

[0833] Then, the compositions are stored for 10 days at 55°C, at atmospheric pressure. The stability of each of the compositions is then evaluated by visual observation.

[0834] It appeared that composition A3 was in the form of a very thick gel, and that composition A4 was in the form of a very brittle, dry and matte gel.

[0835] Thus, the stability of compositions A3 and A4 is unsatisfactory, unacceptable.

[0836] On the other hand, the stability of the compositions Al, A2, B1 and B2 is acceptable. Example 3:

[0837] Compositions Al, A2 and B1 to B2, as described above in Example 2, were prepared.

[0838] Two mixtures are then made.

[0839] Composition Al is mixed with composition B1 at a mass ratio of 50 / 50 to obtain composition CL

[0840] Composition A2 is mixed with composition B2 at a mass ratio of 50 / 50 to obtain composition C2.

[0841] Thus, compositions Cl and C2 are compositions according to the invention.

[0842] Then, composition D as described below was prepared: quantities are expressed in g of raw material as is / 100g.

[0843] [Tables3] Compositions D Organopolysiloxane with carboxylic group(7) 2 Isododecane qsp 100

[0844] (7) sold by SHIN ETSU under the trade name X-22-3701E Protocol:

[0845] Each of the compositions Cl to C2 is applied to strands of dry natural hair that is 90% white, at a rate of 0.5g of composition per gram of strand.

[0846] The hair strands are then dried with a hairdryer and combed.

[0847] Then, composition D is applied to said dry hair strands treated with compositions Cl to C2, at a rate of 0.5g of composition per gram of strand.

[0848] The hair strands are then left at room temperature for 24 hours.

[0849] The hair strands thus colored are then subjected to a test of several repeated shampooings to assess the tenacity (residual effect) of the co The color obtained with shampoos, according to the shampoo protocol described below. Shampoo protocol:

[0850] The colored hair strands are combed, moistened under water at 35°C before being passed between the fingers 5 times for 5 seconds. The hair strands are then squeezed between two fingers.

[0851] A standard shampoo (Garnier Ultra Doux) is applied evenly to the colored strands at a rate of 0.4g of standard shampoo per gram of strands, gently massaging the strands of hair along their length (6 passes) for 15 seconds, from root to tip.

[0852] The strands of hair are then placed in a watch glass and left to rest for 1 minute.

[0853] Next, the hair strands are rinsed with water by passing the strand between the fingers (15 passes). The hair strands are then squeezed dry between two fingers before the next shampoo.

[0854] Once the tests of several shampoos have been carried out, the strands of hair are combed and dried with a hairdryer. Results :

[0855] The persistence of the color of the strands was evaluated in the CIE L*a*b* system, using a Minolta Spectrophotometer CM3600A colorimeter (illuminant D65, angle 10°, specular component included).

[0856] In this L*a*b* system, L* represents the intensity of the color, a* indicates the green / red color axis and b* the blue / yellow color axis.

[0857] The permanence of the color is assessed by the color difference AE between the colored strands before shampooing, and then after 5 shampoos according to the protocol described above. The lower the AE value, the more the color remains after shampooing.

[0858] The value of AE is calculated according to the following equation:

[0859] ¥ ur 2

[0860] In this equation, L*a*b* represent the values ​​measured after hair coloring and after shampooing, and Lo*ao*bo* represent the values ​​measured after hair coloring but before shampooing.

[0861] [Tables4] Composition Cl +D (invention) Number of shampoos L* a* b* AE 0 34.8 28.1 21.9 - 5 42.9 21.4 16.8 11.7 C2 + D (invention) 0 35.2 28.3 22.4 - 5 37.2 26.2 19.9 3.8

[0862] Hair strands treated with each of the compositions (Cl and C2) + D, and washed with five shampoos, exhibit low AE values. Thus, the colored coating obtained with the compositions (Cl and C2) + D shows good shampoo retention.

[0863] In addition, a homogeneous and smooth colour coating on the hair can be observed.< / c>
