Description

Technical Field

[0001] This invention relates to the field of cosmetic treatments of keratin fibers, preferably hair. Therefore, the present invention aims to provide novel compositions comprising a specific copolymer containing acetoacetate units combined with two types of hydrocarbon compounds, which offer excellent technical properties, particularly in terms of the uniformity and abrasion characteristics of the coatings they enable.

[0002] More specifically, the present invention relates to a composition intended for treating human keratin fibers such as hair, comprising a copolymer formed from monomers having acetoacetate functional groups and C6 to C6... 16 Hydrocarbon compounds and two types of C4-C compounds containing at least two oxygen atoms 30 A combination of oxygen-containing hydrocarbon compounds.

[0003] The present invention also relates to a method of using the composition to treat keratin fibers such as hair. Background Technology

[0004] In the field of processing keratin fibers, particularly hair fibers, it is known to use one or more film-forming polymers to obtain high-quality deposits of the product on the fibers.

[0005] Document WO 2013 / 103528 proposes a non-organized copolymer in particulate form, one of whose monomers carries an acetoacetate functional group, particularly for hair applications. Document WO 2014 / 098052 proposes an acrylic resin emulsion for use as a setting agent, which has been stably dispersed with polyvinyl alcohol resin. However, the compositions described in these documents exhibit unsatisfactory hold-up over time.

[0006] In addition, "hair cosmetic" products have recently been developed that offer temporary hair color that lasts for 1 to 3 shampoo washes. For consumers, these are a particularly attractive alternative to permanent hair coloring, provided that the color effect is maintained with good abrasion properties upon contact with water and several shampoo washes. This requirement can be met, in particular, by using effective film-forming agents.

[0007] Therefore, for this purpose, document FR 2 741 530 proposes the use of a dispersion of film-forming polymer particles containing at least one acidic functional group and at least one pigment dispersed in a continuous phase of said dispersion for temporary coloring of keratin fibers. However, the coloring obtained by this dyeing method has the disadvantage of being removed too quickly when washed with shampoo.

[0008] Furthermore, FR 2 907 678 proposes the use of a composition comprising a polysiloxane / polyurea block copolymer and a pigment to produce colored hair coatings. However, with this composition, the resulting coating is not always very uniform, and the hair strand separation is not always satisfactory.

[0009] Therefore, there remains a need for compositions that can deposit colored or colorless coatings on keratin fibers, which are potent and uniform, while being resistant to shampoo washing, sebum, and various aggressors that hair may be subjected to, such as brushing and / or friction.

[0010] This invention enables these needs to be met. Summary of the Invention

[0013] Applying this composition to keratin fibers results in a particularly uniform coating. It provides a water-resistant coating, especially resistant to shampoo and sebum. This coating is resistant to various external aggressors that keratin fibers may be subjected to, such as blow-drying, brushing, friction, and sweat.

[0108] Pigments that can be used are selected, in particular, from organic and / or mineral pigments known in the art, especially from Kirk-Othmer. Encyclopedia of Chemical Technology Those described in the Kirk-Osmer Encyclopedia of Chemical Technology and Ullmann's Encyclopedia of Industrial Chemistry.

[0109] They can be natural, of natural origin, or non-natural.

[0110] These pigments can be in the form of pigment pastes or powders. They can be coated or uncoated.

[0111] Pigments can be selected from mineral pigments, organic pigments, lakes, special effects pigments such as mother-of-pearl or glitter and mixtures thereof.

[0112] The pigment can be a mineral pigment. The term "mineral pigment" refers to any pigment that meets the definition in the chapter on inorganic pigments in Ullmann's encyclopedia. Among the mineral pigments available in this invention, iron oxides, chromium oxides, manganese violet, ultramarine, chromium hydrate, iron blue, and titanium oxides may be mentioned.

[0113] Pigments can be organic pigments. The term "organic pigment" refers to any pigment that meets the definition in the chapter on organic pigments in Ullmann's Encyclopedia.

[0114] Organic pigments can be selected in particular from nitroso, nitro, azo, xanthene, pyrene, quinoline, anthraquinone, triphenylmethane, fluorane, phthalocyanine, metal complexes, isoindolineone, isoindoline, quinacridone, violetone, perylene, diketonepyrrolopyrrole, indigo, thioindigo, dioxazine, triphenylmethane, and quinoline phthalocyanine compounds.

[0115] Specifically, white or colored organic pigments may be selected from carmine, carbon black, aniline black, azo yellow, quinacridone, phthalocyanine blue, blue pigments numbered CI 42090, 69800, 69825, 74100, and 74160 in the Color Index; yellow pigments numbered CI 11680, 11710, 19140, 20040, 21100, 21108, 47000, and 47005 in the Color Index; green pigments numbered CI 61565, 61570, and 74260 in the Color Index; and pigments numbered CI 42090, 69800, 69825, 74100, and 74160 in the Color Index.

[0117] 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 for attaching an organic pigment to the core, and at least one organic pigment that at least partially covers the core.

[0118] Organic pigments can also be lakes. The term "lake" refers to a dye adsorbed onto insoluble particles, thereby forming an assembly that remains insoluble during use.

[0119] The inorganic substrates on which the dye is adsorbed are, for example, alumina, silicon dioxide, sodium calcium borosilicate, or aluminum calcium borosilicate and aluminum.

[0120] Among these dyes, carmine acid may be mentioned. Dyes known by the following names may also be mentioned: 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 5 (CI 61 570), D&C Yellow 10 (CI 77 002), D&C Green 3 (CI 42 053), and D&C Blue 1 (CI 42 090).

[0121] An example of a lake that may be mentioned is a product known by the following name: D&C Red 7 (CI 15 850:1).

[0122] Pigments can also be special effects pigments. The term "special effects pigment" refers to pigments that typically produce an uneven colored appearance (characterized by a certain chroma, vivacity, and brightness level) that varies with viewing conditions (light, temperature, viewing angle, etc.). Therefore, they differ from colored pigments that provide standard, uniform opaque, translucent, or transparent hues.

[0123] There are several types of special effect pigments: those with low refractive index, such as fluorescent or photochromic pigments, and those with high refractive index, such as mother-of-pearl, interference pigments, or glitter sheets.

[0124] Examples of special effects pigments that may be mentioned include pearlescent pigments, such as mica coated with titanium or bismuth oxychloride; colored pearlescent pigments, such as mica coated with titanium and iron oxides, mica coated with iron oxides, mica coated with titanium and especially with iron blue or chromium oxides, mica coated with titanium and organic pigments as previously defined, and also pearlescent pigments based on bismuth oxychloride. Pearlescent pigments that may be mentioned include Cellini (mica-TiO2-lake) marketed by BASF, Prestige (mica-TiO2) marketed by Eckart, Prestige Bronze (mica-Fe2O3) marketed by Eckart, and Colorona (mica-TiO2-Fe2O3) marketed by Merck.

[0125] Also noteworthy are the golden mother-of-pearls sold by BASF under the names Brilliant Gold 212G (Timica), Gold 222C (Cloisonne), Sparkle Gold (Timica), Gold 4504 (Chromalite), and Monarch Gold 233X (Cloisonne); the bronze mother-of-pearls sold by Merck under the names Bronze Fine (17384) (Colorona) and Bronze (17353) (Colorona), and by BASF under the name Super Bronze (Cloisonne); the orange mother-of-pearls sold 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); and the mother-of-pearls sold by BASF under the names Nu-antique Copper 340XB (Cloisonne) and Brown. Brown mother-of-pearl sold under CL4509 (Chromalite); particularly copper-toned mother-of-pearl sold by BASF under the name Copper 340A (Timica); particularly red-toned mother-of-pearl sold by Merck under the name Sienna Fine (17386) (Colorona); particularly yellow-toned mother-of-pearl sold by BASF under the name Yellow (4502) (Chromalite); particularly red-toned mother-of-pearl sold by BASF under the name Sunstone G012 (Gemtone); particularly pink mother-of-pearl sold by BASF under the name Tan Opale G005 (Gemtone); particularly black mother-of-pearl sold by BASF under the name Nu-antique Bronze 240 AB (Timica); particularly blue mother-of-pearl sold by Merck under the name Matte Blue (17433) (Microna); particularly mother-of-pearl sold by Merck under the name Xirona Silver sells white mother-of-pearl with a silvery hue; and especially Merck sells gold-green, pink, and orange mother-of-pearl under the name Indian Summer (Xirona); and mixtures thereof.

[0126] As another example of mother-of-pearl, we can also mention particles comprising a borosilicate substrate coated with titanium dioxide.

[0127] The particles containing titanium oxide-coated glass substrates are particularly sold by Toyal Corporation under the name Metashine MC1080RY.

[0128] Finally, examples of mother-of-pearl that can also be mentioned include polyethylene terephthalate glitter flakes, especially those marketed by Meadowbrook Inventions under the name Silver 1P 0.004X0.004 (Silver Glitter Flakes). Multilayer pigments based on synthetic substrates, such as alumina, silica, sodium calcium borosilicate, aluminum calcium borosilicate, and aluminum, are also conceivable.

[0129] Special effect pigments can also be selected from reflective particles, particularly those whose size, structure, especially the thickness of the layer to which they are made, as well as their physical and chemical properties and surface condition, allow them to reflect incident light. If appropriate, when applied to a carrier to be made up, this reflection can have an intensity sufficient to produce visible highlights on the surface of the composition or mixture, i.e., points that make them appear shimmering and brighter in contrast to their environment.

[0130] Reflective particles can be selected so as not to significantly alter the coloring effect produced by the colorants combined with them, and more specifically, to optimize this effect in color reproduction. They can more specifically have yellow, pink, red, bronze, orange, brown, gold and / or copper colors or hues.

[0131] These particles can take different forms and can be in particular flake or spherical form, especially spherical form.

[0132] Regardless of their form, reflective particles may or may not have a multilayer structure, and in the case of a multilayer structure, they may have, for example, at least one layer of reflective material of uniform thickness.

[0133] When reflective particles do not have a multilayer structure, they can be composed of, for example, metal oxides, especially synthetically obtained titanium oxide or iron oxide.

[0134] When reflective particles have a multilayer structure, they may include, for example, natural or synthetic substrates, particularly synthetic substrates at least partially coated with a layer of at least one reflective material, especially at least one metal or metallic material. The substrate may be made of one or more organic and / or mineral materials.

[0135] More specifically, it can be selected from glass, ceramics, graphite, metal oxides, alumina, silicon dioxide, silicates (especially aluminosilicates and borosilicates), and synthetic mica, and mixtures thereof, and this list is not restrictive.

[0136] Reflective materials may include a metal layer or a layer of metallic material.

[0137] Reflective particles are particularly described in JP-A-09188830, JP-A-10158450, JP-A-10158541, JP-A-07258460 and JP-A-05017710.

[0138] Furthermore, as an example of reflective particles comprising mineral substrates coated with a metal layer, particles comprising borosilicate substrates coated with silver can also be mentioned.

[0139] The sheet-like particles with a silver-coated glass substrate are sold by Toyo Co., Ltd. under the name Microglass Metashine REFSX 2025 PS. Particles with a nickel / chromium / molybdenum alloy-coated glass substrate are sold by the same company under the names Crystal Star GF 550 and GF 2525.

[0140] Particles containing a metal substrate, such as silver, aluminum, iron, chromium, nickel, molybdenum, gold, copper, zinc, tin, magnesium, steel, bronze, or titanium, may also be used. The substrate is coated with a layer of at least one metal oxide, such as titanium oxide, aluminum oxide, iron oxide, cerium oxide, chromium oxide, silicon oxide, and mixtures thereof.

[0141] Examples that may be mentioned include aluminum powder, bronze powder, or copper powder coated with SiO2, which is sold by ECAR under the name Visionaire.

[0142] Interference pigments that are not attached to the substrate can also be mentioned, such as liquid crystals (Helicones HC from Wacker) or interference holographic glitter sheets (Geometric Pigments or Spectraf / x from Spectratek). Special effects pigments also include fluorescent pigments (whether these fluoresce in sunlight or produce ultraviolet fluorescence), phosphorescent pigments, photochromic pigments, thermochromic pigments, and quantum dots (such as those sold by QuantumDots Corporation).

[0143] The various pigments that can be used in this invention enable a wide range of colors to be obtained, as well as specific optical effects, such as metallic or interference effects.

[0144] The pigments used in the compositions according to the invention are typically between 10 nm and 200 µm, preferably between 20 nm and 80 µm, and more preferably between 30 nm and 50 µm.

[0145] Pigments can be dispersed in the composition using dispersants.

[0146] Dispersants are used to protect dispersed particles from agglomeration or flocculation. The dispersant can be a surfactant, oligomer, polymer, or mixture thereof carrying one or more functional groups with a strong affinity for the surface of the particles to be dispersed. In particular, they can become physically or chemically attached to the surface of the pigment. These dispersants also contain at least one functional group that is compatible with or soluble in the continuous medium. Specifically, esters of 12-hydroxystearic acid and esters of C8 to C20 fatty acids, as well as esters of polyols such as glycerol or diglycerol, are used, such as poly(12-hydroxystearic acid) stearate with a molecular weight of about 750 g / mol, such as the product sold by Avecia under the name Solsperse 21 000, polyglycerol-2-dimeric hydroxystearate (CTFA name) sold by Henkel under the index number Dehymyls PGPH, or polyhydroxystearic acid such as the product sold by Lirkma under the index number Arlacel P100, and mixtures thereof.

[0147] As other dispersants that can be used in the compositions of the present invention, quaternary ammonium derivatives of condensed fatty acids, such as Solsperse 17 000 sold by Avecia, and polydimethylsiloxane / oxypropylene mixtures, such as those sold by Dow Corning under index numbers DC2-5185 and DC2-5225 C, may be mentioned.

[0148] The pigments used in the composition can be surface-treated with organic reagents.

[0149] Therefore, the pre-treated pigments used in the context of this invention are pigments that have undergone, in whole or in part, chemical, electronic, electrochemical, mechanochemical, or mechanical surface treatment with organic reagents, and are then dispersed in the compositions according to the invention, such organic reagents as those specifically described in Cosmetics and Toiletries, February 1990, Vol. 105, pp. 53-64. These organic reagents may be selected, 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 and 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 acid polymers, such as polymethyl methacrylate; polymers and copolymers containing acrylate units; alkanolamines; silicone compounds, such as silicones, especially polydimethylsiloxane; organofluorine compounds, such as perfluoroalkyl ethers; fluorosilicone compounds.

[0150] Surface-treated pigments that can be used in the composition may have been treated with mixtures of these compounds and / or may have undergone several surface treatments.

[0151] The surface-treated pigments used in the context of this invention can be prepared according to surface treatment techniques well known to those skilled in the art, or can be commercially available as is.

[0152] Preferably, the surface-treated pigment is coated with an organic layer.

[0153] Organic reagents for treating pigments can be deposited on pigments through solvent evaporation, chemical reactions between surface agent molecules, or the formation of covalent bonds between the surface agent and the pigment.

[0154] Surface treatment can therefore be performed, for example, by a chemical reaction between a surface agent and the pigment surface, and the formation of covalent bonds between the surface agent and the pigment or filler. This method is particularly described in patent US 4,578,266.

[0155] Organic reagents that are covalently bonded to pigments are preferred.

[0156] The reagent used for surface treatment may account for 0.1% to 50% by weight of the total weight of the surface-treated pigment, preferably 0.5% to 30% by weight of the total weight of the surface-treated pigment, and even more preferably 1% to 20% by weight.

[0157] Preferably, the surface treatment agent for the pigment is selected from the following treatment agents: - PEG-silicone treatment agents, such as AQ surface treatment agents sold by LCW; - Polymethylsiloxane treatment agents, such as SI surface treatment agents sold by LCW; - Polydimethylsiloxane treatment agents, such as Covasil 3.05 surface treatment agent sold by LCW; - Polydimethylsiloxane / trimethylsiloxane treatment agents, such as Covasil 4.05 surface treatment agent sold by LCW; - Magnesium myristate treatment agents, such as MM surface treatment agents sold by LCW; - Aluminum dimyristate treatment agents, such as MI surface treatment agents sold by Miyoshi Corporation; - Perfluoropolymethyl isopropyl ether treatment agents, such as FHC surface treatment agents sold by LCW; - Sebacic acid isostearyl ester treatment agent, such as HS surface treatment agent sold by Miyoshi Chemical Co., Ltd.; - Perfluoroalkyl phosphate treatment agents, such as PF surface treatment agents sold by Daito Corporation; - Acrylic ester / polydimethylsiloxane copolymer and perfluoroalkyl phosphate treatment agents, such as FSA surface treatment agent sold by Daito Co., Ltd.; - Polymethylhydrosiloxane / perfluoroalkyl phosphate treatment agents, such as FS01 surface treatment agent sold by Daito Co., Ltd.; - Acrylic ester copolymer / polydimethylsiloxane treatment agents, such as ASC surface treatment agent sold by Daito Co., Ltd.; - Triisostearate titanate isopropyl ester treatment agent, such as ITT surface treatment agent sold by Daito Co., Ltd. - Acrylic copolymer treatment agents, such as APD surface treatment agent sold by Daito Co., Ltd.; - Perfluoroalkyl phosphate / triisostearate titanate treatment agents, such as PF + ITT surface treatment agent sold by Daito Co., Ltd.

[0158] According to a specific embodiment of the invention, the dispersant is present together with organic or mineral pigments in the form of submicron-sized particles.

[0159] The term "submicron size" or " submicron "" refers to the pigment having been micronized by a micronization method and having an average particle size of less than micrometers (µm), particularly between 0.1 and 0.9 µm, and preferably between 0.2 and 0.6 µm.

[0160] According to one embodiment, the dispersant and pigment are present in an amount of (dispersant: pigment) according to a weight ratio between 1:4 and 4:1, particularly between 1.5:3.5 and 3.5:1, or even better between 1.75:3 and 3:1.

[0161] Therefore, dispersants can have a silicone backbone, such as silicone polyether and amino silicone type dispersants. Among suitable dispersants, the following can be mentioned: - Amino silicones, i.e., silicones containing one or more amino groups, such as those sold under the following names and index numbers: BYK LPX 21879 from BYK Chemical Company, and GP-4, GP-6, GP-344, GP-851, GP-965, GP-967, and GP-988-1 sold by Genesee Polymers. - Silicone acrylates, such as Tego® RC 902, Tego® RC 922, Tego® RC 1041 and Tego® RC 1043 sold by Evonik. - Carboxyl-containing polydimethylsiloxane (PDMS) silicones such as Shin-Etsu's X-22162 and X-22370, epoxy silicones such as Genecast Polymers' GP-29, GP-32, GP-502, GP-504, GP-514, GP-607, GP-682 and GP-695, or Evonik's Tego® RC 1401, Tego® RC 1403 and Tego® RC 1412.

[0162] According to a specific embodiment, the dispersant is of the aminosilicone type and is cationic.

[0165] Preferably, the pigment is selected from iron oxide, especially red, brown, or black iron oxide. As an example of iron oxide, one may mention iron oxide sold by Sun Chemical under the name SunPuro® Red Iron Oxide.

[0166] Direct dyes

[0167] The compositions according to the present invention may contain one or more direct dyes.

[0168] The term "direct dyes" refers to natural and / or synthetic dyes, excluding oxidative dyes. These are dyes that are superficially spread onto fibers. They can be ionic, such as cationic or anionic, or nonionic.

[0169] Examples of suitable direct dyes that may be mentioned include azo direct dyes; (poly)methimide dyes, such as cyanine, hemicyanine and styryl dyes; carbonyl dyes; azazine dyes; nitro(hetero)aryl dyes; tri(hetero)arylmethane dyes; porphyrin dyes; phthalocyanine dyes and natural direct dyes, either alone or in mixtures.

[0238] The present invention also relates to the use of the composition for the care of keratin fibers, and particularly hair.

[0239] In the context of processing methods, its uses are as described above.

[0240] The invention will now be described in more detail by way of examples, which do not in any way limit the scope of the invention. However, these examples enable the display of specific features, variations, and preferred embodiments of the invention.

[0241] Example

[0242] The following examples use isobutyl acrylate / tert-butyl acrylate / acetylacetoxyethyl methacrylate (25 / 65 / 10) copolymer CP synthesized according to the scheme described below: 62.5 g of isobutyl acrylate, 162.5 g of tert-butyl acrylate, 25 g of acetyl methacrylate, 2.5 g of Trigonox T21S radical initiator, and 360 g of isododecane / ethyl acetate (50 / 50) solvent were introduced into a 1 L pilot reactor. The medium was degassed with argon and then heated to 90°C with stirring. The reaction medium was maintained at 90°C for 7 hours. Then, stripping with 300 ml of isododecane was performed to remove residual monomers. At the end of the reaction, a polymer in solution in isododecane was obtained.

[0243] Example 1: Preparation of the composition

[0244] The following compositions were prepared by mixing the ingredients indicated in Table 1 below, wherein the content is expressed as a weight percentage of the starting material relative to the total weight of the composition (am represents the active material).

[0245] [Table 1]

[0246] (1) The isobutyl acrylate / tert-butyl acrylate / acetyl acetoxyethyl methacrylate (25 / 65 / 10 by weight) statistical copolymer obtained according to the preparation method described above is used as a solution of 65.4% by weight in isododecane; (2) Sold by Titan Kogyo under the name Tarox Iron Oxide R-516 HP.

[0247] Example 2: Evaluation of the composition

[0248] Compositions A to C from Example 1 were evaluated on a 1 g strand of natural hair containing 90% gray hair.

[0249] The application plan is as follows: Apply each composition to a section of dry hair at a ratio of 0.6 g of the composition (0.6 g / g hair bath ratio). Spread it on the hair section with your fingers.

[0250] After a 2-minute leave-on time, dry the hair strands using a hot brush and a hairdryer.

[0251] Then, the tolerance to shampoo washing was evaluated 24 hours after the application of the composition. Tolerance to shampoo washing was evaluated by measuring colorimetric data for each hair strand.

[0252] Colorimetric measurements were performed in the CIELab system using a Konica Minolta 3600 spectrochromista (light source D65, angle 10°, including specular reflection component).

[0253] In the L a b In the system, L Indicates the brightness of a color, a Indicates the green / red axis and b Indicates the blue / yellow axis.

[0254] L The smaller the value, the stronger the coloring.

[0255] Color retention was evaluated by the color difference ΔE between colored hair strands before shampoo washing and after five consecutive shampoo washes. The lower the ΔE value, the longer the color lasts relative to shampoo washing.

[0256] Calculate the value of ΔE according to the following equation:

[0257] In this equation, L a and b This indicates the value measured after the hair has been colored and after five shampoo washes, and L0 a0 and b0 This indicates the value measured after the hair has been colored but before five shampoo washes.

[0258] The results are summarized in Table 2 below.

[0259] [Table 2]

[0260] Compared to the comparative composition, the two compositions according to the invention produce stronger color (lower L) before undergoing five shampoo washes. value).

[0261] Hair strands colored with the two compositions according to the invention exhibit a much smaller color difference ΔE between the colored strands before shampoo washing and after five shampoo washes than those colored with composition A. Therefore, the durability of the coloring obtained with compositions B and C according to the invention is significantly improved compared to the coloring obtained with comparative composition A.

[0262] Therefore, the colored coating obtained by means of the composition according to the invention has stronger coloring and improved durability compared to shampoo washing.
