Description

Technical Field

[0001] The present invention relates to a hair coloring composition comprising at least one (poly)carbodiimide compound and at least one compound having at least one hydroxyl functional group.

[0002] The subject of the present invention is also a method for coloring hair keratin fibers, which method comprises applying said composition, and also an apparatus for coloring hair keratin fibers.

Background Art

[0003] In the field of coloring hair keratin fibers, particularly human hair keratin fibers, it is already known to color hair keratin fibers via various techniques using direct dyes or pigments for non-permanent coloring or dye precursors for permanent coloring.

[0004] There are essentially three methods for coloring hair. a) "Permanent" coloring: Its action can significantly modify the original color, penetrate the hair fibers, and uses oxidation dyes that generate pigments via an oxidative condensation process. b) Non-permanent, semi-permanent or direct dyes: Do not use the oxidative condensation process and withstand 4 - 5 shampoo washings. This involves coloring the hair keratin fibers using a coloring composition containing direct dyes. c) Temporary coloring: Modifies the original color of the hair, remains from the first shampoo wash to the next shampoo wash, and serves to enhance or correct the already obtained color tone. This can also be associated with the "makeup" method.

[0005] Regarding the last-mentioned type of coloring, a technique using a colored polymer produced by grafting one or more dyes having the properties of azo, triphenylmethane, azine, indamine or anthraquinone onto a polymer chain is known. Such colored polymers are not entirely satisfactory, particularly with regard to the uniformity of the colored color and its resistance, and needless to say, with regard to the problems associated with their production, particularly reproducibility.

[0006] Another coloring method involves using pigments. Specifically, when pigments are used on the surface of hair keratin fibers, the pigments on the surface can hide the original color of the fibers, making it possible to achieve coloring that can be recognized even on generally dark-colored hair. However, the coloring obtained by this coloring method has the drawback that it is inferior not only in resistance to shampoo washing but also in resistance to external agents such as sebum, sweat, brushing and / or friction.

[0007] Furthermore, compositions for temporary hair coloring may also have a working quality that is not entirely satisfactory, particularly with regard to texture and ease of spreading and / or uniformity on the hair.

[0008] Therefore, there is still a need for a composition for coloring hair keratin fibers that has the advantage of producing a uniform and smooth coloring coating on the hair, while at the same time forming a coat that is resistant to shampoo washing and various attacking factors that the hair may be subjected to, such as brushing and / or friction without deteriorating the hair, and has good stability over time and good storage over time, i.e., good protection against microorganisms and good working quality. Summary of the Invention Problems to be Solved by the Invention

[0009] Accordingly, an object of the present invention is to have the advantage of generating a uniform and smooth coloring coating on the hair, and at the same time, to form a coat that can withstand various attack factors that the hair may receive, such as shampoo washing and brushing and / or friction, without degrading the hair, and also has good stability over time and good storage over time, i.e., good protection against microorganisms and good working quality. The object is to develop a hair coloring composition.

Means for Solving the Problems

Embodiments for Carrying Out the Invention

[0013] With the coloring composition C according to the invention, a colored coating is obtained on the hair, thereby making it possible to obtain a visible coloring on all hair types that is persistent with respect to shampooing and at the same time maintains the physical quality of the hair keratin fibers. This type of coating can withstand drying by blowing and external aggressors to which the hair can be exposed, such as sweat. It gives a particularly smooth and uniform deposit.

[0014] Furthermore, the color composition C according to the invention has good stability over time, particularly after a storage period at a temperature in the range of room temperature or up to 45°C. The color composition C according to the invention also has good storage over time, i.e., good protection against microorganisms, particularly after a storage period of up to two months at a temperature in the range of room temperature or up to 55°C.

[0101] Examples of lakes can include products known by the following names: D&C Red 7 (CI 15 850:1).

[0102] The pigment can be a special effect pigment. The term "special effect pigment" generally means a pigment that produces a non-uniform and colored appearance (characterized by a specific hue, a specific brilliance and a specific level of luminance) that varies according to the conditions of observation (light, temperature, angle of observation, etc.). Thereby, they are different from colored pigments that exhibit standard uniform opaque, translucent or transparent hues.

[0103] There are several types of special effect pigments: those with a low refractive index such as fluorescent or photochromic pigments and those with a high refractive index such as nacreous pearlescent agents, interference pigments or glitter flakes.

[0104] Examples of pigments with special effects that may be mentioned include nacreous pearlescent pigments such as mica coated with titanium or bismuth oxychloride, colored nacreous pearlescent pigments such as mica coated with titanium and iron oxide, mica coated with iron oxide, mica coated with titanium, especially mica coated with Prussian blue or chromium oxide, mica coated with titanium and coated with an organic pigment as defined above, and nacreous pearlescent pigments based on bismuth oxychloride.

[0106] As a further example of nacreous pearlescent agents, particles comprising a borosilicate substrate coated with titanium oxide may also be mentioned.

[0107] Particles comprising a glass substrate coated with titanium oxide are sold, in particular, by Toyal under the name Metashine MC1080RY.

[0108] Finally, as an example of nacreous pearlescent agents, polyethylene terephthalate glitter flakes, especially those sold by Meadowbrook Inventions under the name Silver 1P 0.004X0.004 (silver glitter flakes) may also be mentioned. Multilayer pigments based on synthetic substrates such as alumina, silica, calcium sodium borosilicate, calcium aluminum borosilicate and aluminum etc. can also be envisaged.

[0109] Pigments with special effects can also be selected from reflective particles, i.e. particles capable of reflecting incident light due to their size, structure, in particular the thickness of the layers that make them up, as well as their physical and chemical properties and surface state. This reflection can, where appropriate, create highlight points visible to the naked eye on the surface of the composition or mixture when it is applied to the support on which it is constituted, i.e. brighter points that appear to shine compared to their surroundings with sufficient intensity to do so.

[0110] The reflective particles can be selected so as not to significantly change the color effect brought about by the colorant combined therewith, and more specifically to optimize this effect from the viewpoint of color rendering. These can more specifically have colors or shades of yellow, pink, red, bronze, orange, brown, gold and / or copper.

[0111] These particles can have various forms, especially in the form of small plates or small spheres, particularly spherical form.

[0112] Regardless of their form, the reflective particles may or may not have a multilayer structure. In the case of a multilayer structure, for example, they may have at least one layer of a reflective material, especially with a uniform thickness.

[0113] When the reflective particles do not have a multilayer structure, they can be composed of metal oxides, especially titanium oxide or iron oxide obtained by synthesis.

[0114] When the reflective particles have a multilayer structure, they can include, for example, a natural or synthetic substrate, especially a synthetic substrate, at least partially coated with at least one layer of a reflective material, especially at least one metal or metallic material. The substrate can be made from one or more organic materials and / or mineral materials.

[0115] More specifically, this can be selected from, but is not limited to, the list of glass, ceramics, graphite, metal oxides, alumina, silica, silicates, especially aluminosilicates and borosilicates, and synthetic mica, and mixtures thereof.

[0116] The reflective material can include a layer of a metal or metallic material.

[0117] The reflective particles are described, in particular, in JP-A-09-188830, JP-A-10-158450, JP-A-10-158541, JP-A-07-258460, and JP-A-05-017710.

[0118] As a further example of reflective particles including an inorganic substrate coated with a metal layer, particles including a borosilicate substrate coated with silver can also be mentioned.

[0119] Particles of the silver-coated glass substrate in the form of small plates are sold by Toyal under the name Microglass Metashine REFSX 2025 PS. Particles of the glass substrate coated with a nickel / chromium / molybdenum alloy are sold by the company under the names Crystal Star GF 550 and GF 2525.

[0120] Particles containing a metal substrate such as silver, aluminum, iron, chromium, nickel, molybdenum, gold, copper, zinc, tin, magnesium, steel, bronze or titanium can also be used, and the substrate is coated with at least one layer of at least one metal oxide such as titanium oxide, aluminum oxide, iron oxide, cerium oxide, chromium oxide, silicon oxide and mixtures thereof.

[0121] Examples thereof include aluminum powder, bronze powder or copper powder coated with SiO2, sold by Eckart under the name Visionaire.

[0122] Pigments showing interference effects such as liquid crystals (Helicones HC from Wacker) or holographic glitter flakes (Geometric Pigments from Spectratek or Spectra f / x) not bonded to the substrate can also be mentioned. Pigments with special effects include fluorescent pigments (either substances that fluoresce in daylight or substances that produce ultraviolet fluorescence), phosphorescent pigments, photochromic pigments, thermochromic pigments and quantum dots sold, for example, by Quantum Dots Corporation.

[0123] The diversity of pigments that can be used in the composition according to the present invention makes it possible to obtain a wide range of colors and also to obtain specific optical effects such as metallic effects or interference effects.

[0124] The size of the pigments used in the composition according to the present invention is generally from 10 nm to 200 μm, preferably from 20 nm to 80 μm, and more preferably from 30 nm to 50 μm.

[0125] The pigment can be dispersed in the composition by a dispersant.

[0126] The dispersant serves to prevent aggregation or soft aggregation of the dispersed particles. This dispersant can be a surfactant, oligomer, polymer or a mixture of several of these having one or more functional groups with a strong affinity for the surface of the particles to be dispersed. In particular, these can be physically or chemically bonded to the pigment surface. These dispersants also contain at least one functional group that is compatible with the continuous medium or soluble in the continuous medium. In particular, 12-hydroxystearic acid, especially esters of C8-C20 fatty acids and polyols such as glycerol or diglycerol, for example poly(12-hydroxystearic acid) stearate with a molecular weight of about 750 g / mol, for example a product sold under the name Solsperse 21000 from Avecia, polyglyceryl-2 dipolyhydroxystearate (CTFA name) sold under the trade symbol Dehymyls PGPH from Henkel or polyhydroxystearic acid, for example a product sold under the trade symbol Arlacel P100 from Uniqema and mixtures thereof are used.

[0127] Other dispersants that can be used in the composition of the present invention include quaternary ammonium derivatives of polycondensed fatty acids, such as Solsperse 17000 sold by Avecia, and polydimethylsiloxane / oxypropylene mixtures, such as those sold under the trade symbols DC2-5185 and DC2-5225 C by Dow Corning.

[0128] The pigment that can be used in the composition can be surface-treated with an organic agent.

[0129] Therefore, the pre-surface-treated pigments useful in connection with the present invention are pigments that have been surface-treated, either fully or partially, with organic agents to modify their chemical, electronic, electrochemical, mechanochemical, or mechanical properties, such as those described in Cosmetics and Toiletries, February 1990, Vol. 105, pp. 53-64. After such treatment, they are dispersed in the compositions of the present invention. These organic agents include, for example, 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; lecithin; sodium, potassium, magnesium, iron, titanium, zinc, or aluminum salts of fatty acids, such as aluminum stearate or aluminum laurate; metal alkoxides; polyethylene; (meth)acrylic polymers such as polymethyl methacrylate; polymers and copolymers containing acrylate units; alkanolamines; silicone compounds such as silicones, especially polydimethylsiloxane; organic fluorine compounds such as perfluoroalkyl ethers; and fluorosilicone compounds, and can be selected therefrom.

[0130] The surface-treated pigments useful in the present composition can be those treated with a mixture of these compounds and / or can be those that have been surface-treated several times.

[0131] The surface-treated pigments useful in connection with the present invention can be prepared according to surface treatment techniques well known to those skilled in the art or can be commercially available as such.

[0132] Preferably, the surface-treated pigments are coated with an organic layer.

[0133] The organic agents used to treat the pigments can be deposited on the pigments by evaporating the solvent, causing a chemical reaction between the molecules of the surface treatment agent, or forming a covalent bond between the surface treatment agent and the pigment.

[0134] Therefore, the surface treatment can be carried out, for example, by causing a chemical reaction between a surface treatment agent and the pigment surface to generate a covalent bond between the surface treatment agent and the pigment or filler. This method is particularly described in U.S. Patent No. 4,578,266.

[0135] Organic agents that covalently bond to the pigment will preferably be used.

[0136] The surface treatment agent can account for 0.1% to 50% by mass, preferably 0.5% to 30% by mass, and more preferably 1% to 20% by mass of the total mass of the pigment to be surface-treated.

[0137] Preferably, the surface treatment agent for the pigment is selected from the following treatment agents: - PEG-silicone treatment agents, such as the AQ surface treatment agent sold by LCW; - Methicone treatment agents, such as the SI surface treatment agent sold by LCW; - Dimethicone treatment agents, such as the Covasil 3.05 surface treatment agent sold by LCW; - Dimethicone / trimethylsiloxysilicate treatment agents, such as the Covasil 4.05 surface treatment agent sold by LCW; - Magnesium myristate treatment agents, such as the MM surface treatment agent sold by LCW; - Aluminum dimyristate treatment agents, such as the MI surface treatment agent sold by Miyoshi Kasei Co., Ltd.; - Perfluoropolyisopropyl methyl ether treatment, such as surface treatment using FHC sold by LCW; - Isostearyl sebacate treatment agents, such as the HS surface treatment agent sold by Miyoshi Kasei Co., Ltd.; - Perfluoroalkyl phosphate treatment agents, such as the PF surface treatment agent sold by Daito Kasei Kogyo Co., Ltd.; - Acrylate / dimethicone copolymer and perfluoroalkyl phosphate treatment agents, such as the FSA surface treatment agent sold by Daito Kasei Kogyo Co., Ltd.; - Polymethylhydrogensiloxane / perfluoroalkyl phosphate treatment agent, such as FS01 surface treatment agent sold by Daito Kasei Kogyo Co., Ltd.; - Acrylate / dimethicone copolymers treatment agent, such as ASC surface treatment agent sold by Daito Kasei Kogyo Co., Ltd.; - Isopropyl titanate triisostearate treatment agent, such as ITT surface treatment agent sold by Daito Kasei Kogyo Co., Ltd.; - Acrylate copolymer treatment agent, such as APD surface treatment agent sold by Daito Kasei Kogyo Co., Ltd.; - Perfluoroalkyl phosphate / isopropyl titanate triisostearate treatment agent, such as PF+ITT surface treatment agent sold by Daito Kasei Kogyo Co., Ltd.

[0138] According to a particular embodiment of the present invention, the dispersant is present together with an organic or mineral pigment in the form of submicron-sized particles.

[0139] The term "submicron" or "submicron-sized" refers to pigments having a particle diameter micronized by a micronization method and having an average particle diameter of less than 1 micrometer (μm), particularly 0.1 to 0.9 μm, preferably 0.2 to 0.6 μm.

[0140] According to one embodiment, the dispersant and the pigment are present in an amount (dispersant:pigment) of 1:4 to 4:1, particularly 1.5:3.5 to 3.5:1 or even more preferably 1.75:3 to 3:1, depending on the mass ratio.

[0144] In a variant of the present invention, the pigment is an organic pigment, preferably an organic pigment surface-treated with an organic agent selected from silicone compounds. In another variant of the present invention, the pigment is a mineral pigment.

[0145] Direct dye The composition C according to the present invention may contain one or more direct dyes.

[0146] The term "direct dye" means natural and / or synthetic dyes other than oxidative dyes. These are dyes that will diffuse superficially onto the fiber.

[0147] These can be ionic or non-ionic, preferably cationic or non-ionic.

[0148] Examples of suitable direct dyes include azo direct dyes, alone or in mixture form; (poly)methine dyes such as cyanine, hemicyanine and styryl; carbonyl dyes; azine dyes; nitro(hetero)aryl dyes; tri(hetero)arylmethane dyes; porphyrin dyes; phthalocyanine dyes; and natural direct dyes.

[0434] Then, this last compound (8) is reacted with 1 eq. of the compound (4’): R1-X1-C(O)-NH-L1-(N=C=N-L1) n -N=C=O (4’) (the compound (4’) can be synthesized by reacting 0.5 eq. of a nucleophile R1-X1-H with 1 equivalent of the compound (3)) to give the (poly)carbodiimide (9) of the present invention: R1-X1-C(O)-NH-L1-(N=C=N-L1) n -NH-C(O)-[E-C(O)-NH-L1-(N=C=N-L1) z w -NHC(O)-X2-R2(9)​​ (In formula (9), L1, R1, X1, R2, X2, n, z, w, and E are as defined above) can be generated.

[0435] (Poly)carbodiimide compounds and all reaction intermediates and reagents as well can be purified by conventional methods known to those skilled in the art, for example, extraction, precipitation, centrifugation, filtration, and / or chromatography using water and an organic solvent immiscible with water.

[0436] Example 1: Method for synthesizing a (poly)carbodiimide compound 50 g of 4,4'-dicyclohexylmethane diisocyanate and 0.5 g of 4,5-dihydro-3-methyl-1-phenyl-1H-phosphole 1-oxide are charged with stirring into a 500 mL three-necked round-bottom flask equipped with a thermometer, a stirrer, and a reflux tube.

[0437] While monitoring the reaction by the absorption of isocyanate groups at 2200 - 2300 cm -1 in infrared spectroscopy, the reaction medium is heated at 140 °C for 4 hours in nitrogen and then cooled to 120 °C.

[0438] A mixture of 5.3 g of polyethylene glycol monomethyl ether and 1.2 g of 1,4-butanediol is introduced into the reaction medium with stirring. While monitoring by infrared spectroscopy at 2200 - 2300 cm -1 the temperature is maintained at 120 °C until the isocyanate groups completely disappear, and then it is cooled to room temperature.

[0439] After cooling to room temperature, the reaction medium is added dropwise with vigorous stirring to a 500 mL glass beaker containing 85 g of distilled water to obtain the desired product in the form of a translucent yellow liquid.

[0440] Example 2 The following compositions A1 - A11 were prepared: The amounts are expressed as g / 100 g of the starting materials obtained.

[0441]

Table 1

[0442]

Table 2

[0443] Therefore, compositions A1 to A8 are the compositions according to the present invention, and compositions A9 to A11 are comparative compositions.

[0444] a. Evaluation of stability When the composition is prepared, the appearance of the composition is observed at T0.

[0445] Compositions A1 to A8 are in the form of a smooth fluid gel.

[0446] Next, the composition is stored at 45 °C and atmospheric pressure for 2 months. Then, the stability of each composition is evaluated by visual observation.

[0447] The stability of compositions A1 to A8 is acceptable.

[0448] b. Evaluation of performance regarding protection from pathogenic bacteria Two tests related to this evaluation are conducted: the "orientation" test and the "confirmation" test.

[0449] Scoring method: The effectiveness of the preservative according to the present invention is evaluated by a challenge test that enables determination of the level of antibacterial protection of the composition.

[0450] It consists of the artificial contamination of the test product by various microorganisms (bacteria, yeasts, and molds) and the monitoring of the number of viable pathogenic bacteria over time.

[0451] Therefore, cleanliness control must be carried out before the start of the test. This makes it possible to confirm that the preparation to be tested in the challenge test is not contaminated or meets the acceptance criteria. Therefore, multiple contaminations are avoided for the accurate progress of the challenge test.

[0452] A sufficiently protected product must enable the decontamination of the introduced microorganisms, and this decontamination is more or less rapid as a function of the microbial strain, the type of product, the conditioning article, etc.

[0453] The product is distributed into as many pill bottles as there are microorganisms to be tested. A calibrated microbial suspension is introduced into each of these bottles to obtain a pathogen content of 10 6 per gram of product (each microbial suspension is counted to determine the exact content inoculated into the product).

[0454] The contaminated product is stored at 32.5 °C ± 2.5 °C for 24 hours or for 48 hours in the case of a mold.

[0455] The effectiveness of the protection of the preparation is tested with a microbial spectrum selected from among the species that are likely to contaminate the product both during manufacture and during its use, although limited.

[0456] The microbial spectrum combines various microorganisms used to conduct challenge tests. It includes gram-positive bacteria (Enterococcus faecalis) for the orientation test, yeast (Candida albicans), and mold (Aspergillus niger), as well as four bacteria (Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Enterococcus faecalis), yeast (Candida albicans), and mold (Aspergillus niger) for the confirmation test.

[0457] Part 1 of the test: Orientation This is a screening test to direct the remaining tests and identify formulations with insufficient protection in a short time. After 7 days of contact between the product and the pathogen, samples are taken for the purpose of counting the microorganisms remaining in the product. Detection limit by this method: 250 cfu / g. Therefore, the most favorable result is less than 250 pathogens / g (no microbial colonies on the dish).

[0458] Part 2 of the test: Confirmation Except in special cases, only the formulations retained at the end of the orientation test can undergo the confirmation process.

[0459] Regarding orientation, after 7 days of contact between the product and the pathogen, the first sample collection is performed to count the microorganisms remaining in the product.

[0460] The main difference between the confirmation process and the orientation process is that two other sample collections are performed to monitor changes in antibacterial protection over time. A sample is taken on the 14th day and another sample is taken on the 28th day. The dilutions made for counting are seeded on Petri dishes. The bacteria remaining in the product are counted. Example: 4.3×105 Pathogenic bacteria / g. Detection limit by this method: 200 cfu / g. Therefore, the most preferable result is less than 200 pathogenic bacteria / g (no microbial colonies are present on the Petri dish). To confirm the stability of the antibacterial protection over time, this test is repeated on the formulation after accelerated aging at 45°C for 2 months.

[0461] The results are collated in the following table.

[0462]

Table 3

[0463] Therefore, the compositions A1 - A8 according to the present invention show good protection against microorganisms, which does not apply to the comparative compositions A9 - A11.

[0464] Therefore, the compositions A1 - A8 according to the present invention show good storage over time.

[0465] Therefore, the composition according to the present invention has both good stability over time and good protection against microorganisms, and thus has good storage over time.

[0466] Example 3: The compositions A3 and A4 described above in Example 2 were prepared.

[0467] Next, the composition B described below was prepared: The amounts are expressed as g / 100 g of the starting materials obtained.

[0468]

Table 4

[0469] Next, two mixing procedures are carried out.

[0470] The composition A3 and the composition B are mixed at a mass ratio of 50 / 50 to obtain the composition C1.

[0471] Mix composition A4 and composition B in a mass ratio of 50 / 50 to obtain composition C2.

[0472] Therefore, compositions C1 and C2 are compositions according to the present invention.

[0473] Next, the following composition D was prepared. The amounts are expressed as g / 100g of the obtained starting materials.

[0474]

Table 5

[0475] Protocol: Each of compositions C1 and C2 is applied to a tuft of dry natural hair containing 90% white hair at a rate of 0.8 g of composition per gram of tuft.

[0476] Next, the hair tresses are dried with a hair dryer and then combed.

[0477] Next, composition D is applied to the said tuft of dry hair treated with compositions C1 and C2 at a rate of 0.5 g of composition per gram of tuft.

[0478] Next, the hair tresses are dried with a hair dryer and then combed. Next, the hair tresses are stored at room temperature and ambient humidity for 24 hours.

[0479] Then, the thus-colored hair tresses are subjected to several repeated shampooing tests in order to evaluate the fastness (persistence) of the colorant obtained with respect to shampooing according to the shampooing protocol described below.

[0480] Shampooing protocol: Comb the colored hair tresses, moisten them with water at 35°C, and then pass them through the fingers 5 times for 5 seconds. Next, wring the hair tresses dry between two fingers.

[0481] Apply a standard shampoo (Garnier Ultra Doux) uniformly to the colored hair bundle at a ratio of 0.4 g of the standard shampoo per 1 g of the hair bundle, and gently knead it along the longitudinal direction of the hair bundle from the root to the tip for 15 seconds (6 times).

[0482] Then place the hair bundle in a watch glass and leave it for 1 minute.

[0483] Then, rinse the hair bundle with water while passing it through the fingers (15 times). Next, wring the hair strands dry between two fingers before the next shampoo wash.

[0484] After finishing the test with several shampoo washes, comb the hair bundle and dry it with a hair dryer.

[0485] Results: The color persistence of the hair bundle was evaluated in the CIE L*a*b* system using a Minolta Spectrophotometer CM3600A colorimeter (D65 light source, 10° angle, including the specular component).

[0486] In this L*a*b* system, L* represents the color intensity, a* represents the green / red axis, and b* represents the blue / yellow axis.

[0487] The color persistence of the coloring is evaluated by the color difference ΔE between before shampooing the dyed hair bundle and after performing 5 shampoo washes according to the procedure described above. The lower the ΔE value, the higher the color persistence against shampoo washing.

[0488] The ΔE value is obtained according to the following formula.

Equation

[0489] In this formula, L*a*b* represents the values measured after performing the shampoo wash after hair dyeing, and L0*a0*b0* represents the values measured before performing the shampoo wash after hair dyeing.

[0490]

Table 6

[0491] The hair tresses treated with each of the compositions (C1 and C2)+D and washed with 5 shampoo washings have low ΔE values. Therefore, the colored coating of the hair keratin fibers obtained using the compositions (C1 and C2)+D shows good persistence with respect to shampoo washing.

[0492] Furthermore, a smooth and uniform color coating on the hair is observed.
