Description
COMPOSITION AND PROCESS FOR DYEING KERATIN FIBERSTECHNICAL FIELD
[0001] The present invention relates to a composition. In particular, the present invention relates to a composition for dyeing the keratin fibers such as the hair. The present invention also relates to a process for dyeing the keratin fibers such as the hair.BACKGROUND ART
[0002] Many people have for a long time sought to modify the color of their hair, and especially to mask their grey hair.
[0003] In the field of dyeing keratin fibers, in particular human keratin fibers, it is already known practice to dye hair keratin fibers via various techniques using direct dyes or pigments for non-permanent dyeing, or dye precursors for permanent dyeing.
[0004] There are essentially three types of process for dyeing the hair:
[0005] a) “permanent” dyeing, the function of which is to afford a substantial modification to the natural color and which uses oxidation dyes which penetrate into the hair fibers and form the dye via an oxidative condensation process;
[0006] b) non-permanent, semi-permanent, or direct dyeing, which does not use the oxidative condensation process and withstands four or five shampoo washes; it consists of dyeing the hair with dye compositions containing direct dyes;
[0007] c) temporary dyeing, which gives rise to a modification of the natural color of the hair that remains from one shampoo wash to the next, and which serves to enhance or correct a shade that has already been obtained. It may also be likened to a “makeup” process.
[0008] The temporary dyeing method consists of using pigments. Specifically, the use of pigment on the surface of keratin fibers generally makes it possible to obtain visible colourings on dark hair, since the surface pigment masks the natural color of the fibers.
[0009] Compositions for temporarily dyeing and / or making up the hair may lead to a hair feel that is uncosmetic and / or not natural; the hair thus dyed may in particular lack softness and / or suppleness and / or strand separation.
[0010] Thus, there is a need to develop a composition for dyeing the keratin fibers such as the hair which has the advantage of good cosmetic properties of the hair such as softness and suppleness while retaining hair with good strand separation.SUMMARY OF THE INVENTION
[0011] One aim of the present application is to provide a composition for dyeing the keratin fibers such as the hair, which presents good cosmetic properties of the hair such as softness and suppleness while retaining hair with good strand separation.
[0012] Another aim of the present application is to provide a process for dyeing the keratin fibers such as the hair.
[0013] Thus, the present invention provides a composition, preferably for dyeing the keratin fibers such as the hair, comprising:
[0014] a) at least one protein with a molecular weight of at least 10 kDa;
[0015] b) at least one cationic surfactant chosen from tertiary amidoamine; and
[0016] c) at least one colouring agent chosen from pigments, direct dyes, and mixtures thereof.
[0017] Preferably, the composition according to the present invention is a composition for dyeing the keratin fibers such as the hair.
[0018] The present invention also relates to a process for dyeing the keratin fibers such as the hair comprising applying the composition as described above onto the keratin fibers such as the hair.
[0019] The inventors found that the composition according to the present invention makes it possible to obtain colored coating hairs having good strand separation and a smoother feel, being softer and more supple and which are easy to disentangle.

[0079] They may be natural, of natural origin, or non-natural.
[0080] These pigments may be in pigment powder or paste form. They may be coated or uncoated.
[0081] The pigments may be chosen, for example, from mineral pigments, organic pigments, lakes, pigments with special effects such as nacres or glitter flakes, and mixtures thereof.
[0082] The pigment may be a mineral pigment. The term “mineral pigment” refers to any pigment that satisfies the definition in Ullmann’s encyclopedia in the chapter on inorganic pigments.

[0096] The pigments in accordance with the invention may also be in the form of composite pigments, as described in patent EP 1 184 426. These composite pigments may be composed notably of particles including an inorganic core, at least one binder for attaching the organic pigments to the core, and at least one organic pigment which at least partially covers the core.
[0097] The organic pigment may also be a lake. The term “lake” refers to dyes adsorbed onto insoluble particles, the assembly thus obtained remaining insoluble during use.
[0098] The mineral substrates onto which the dyes are adsorbed are, for example, alumina, silica, calcium sodium borosilicate or calcium aluminum borosilicate and aluminum.
[0099] Among the dyes, mention may be made of carminic acid. Mention may also be made of the dyes 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 5 (CI 61 570) , D&C Yellow 10 (CI 77 002) , D&C Green 3 (CI 42 053) , D&C Blue 1 (CI 42 090) .
[0100] An example of a lake that may be mentioned is the product known under the following name: D&C Red 7 (CI 15 850: 1) .
[0101] The pigment may also be a pigment with special effects. The term “pigments with special effects” means pigments that generally create a coloured appearance (characterized by a certain shade, a certain vivacity, and a certain level of luminance) that is non-uniform and that changes as a function of the conditions of observation (light, temperature, angles of observation, etc. ) . They thereby differ from coloured pigments, which afford a standard uniform opaque, semi-transparent, or transparent shade.
[0102] Several types of pigments with special effects exist: those with a low refractive index, such as fluorescent or photochromic pigments, and those with a higher refractive index, such as nacres, interference pigments, or glitter flakes.
[0103] Examples of pigments with special effects that may be mentioned include nacreous pigments such as mica covered with titanium or with bismuth oxychloride, coloured nacreous pigments such as mica covered with titanium and with iron oxides, mica covered with iron oxide, mica covered with titanium and notably with ferric blue or with chromium oxide, mica covered with titanium and with an organic pigment as defined previously, and also nacreous pigments based on bismuth oxychloride. Nacreous pigments that may be mentioned include the nacres Cellini sold by BASF (mica-TiO2-lake) , Prestige sold by Eckart (mica-TiO2) , Prestige Bronze sold by Eckart (mica-Fe2O3) and Colorona sold by Merck (mica-TiO2-Fe2O3) .
[0104] Mention may also be made of the gold-coloured nacres sold notably by the company BASF under the name Brilliant gold 212G (Timica) , Gold 222C (Cloisonne) , Sparkle gold (Timica) , Gold 4504 (Chromalite) and Monarch gold 233X (Cloisonne) ; the bronze nacres sold notably by the company Merck under the name Bronze fine (17384) (Colorona) and Bronze (17353) (Colorona) and by the company BASF under the name Super bronze (Cloisonne) ; the orange nacres sold notably by the company BASF under the name Orange 363C (Cloisonne) and Orange MCR 101 (Cosmica) and by the company Merck under the name Passion orange (Colorona) and Matte orange (17449) (Microna) ; the brown nacres sold notably by the company BASF under the name Nu-antique copper 340XB (Cloisonne) and Brown CL4509 (Chromalite) ; the nacres with a copper tint sold notably by the company BASF under the name Copper 340A (Timica) ; the nacres with a red tint sold notably by the company Merck under the name Sienna fine (17386) (Colorona) ; the nacres with a yellow tint sold notably by the company BASF under the name Yellow (4502) (Chromalite) ; the red nacres with a gold tint sold notably by the company BASF under the name Sunstone G012 (Gemtone) ; the pink nacres sold notably by the company BASF under the name Tan opale G005 (Gemtone) ; the black nacres with a gold tint sold notably by the company BASF under the name Nu antique bronze 240 AB (Timica) , the blue nacres sold notably by the company Merck under the name Matte blue (17433) (Microna) , the white nacres with a silvery tint sold notably by the company Merck under the name Xirona Silver, and the golden-green pink-orange nacres sold notably by the company Merck under the name Indian summer (Xirona) , and mixtures thereof.
[0105] Still, as examples of nacreous agents, mention may also be made of particles including a borosilicate substrate coated with titanium oxide.
[0106] Particles comprising a glass substrate coated with titanium oxide are notably sold under the name Metashine MC1080RY by the company Toyal.
[0107] Finally, examples of nacres that may also be mentioned include polyethylene terephthalate glitter flakes, notably those sold by the company Meadowbrook Inventions under the name Silver 1P 0.004X0.004 (silver glitter flakes) . It is also possible to envisage multilayer pigments based on synthetic substrates, such as alumina, silica, calcium sodium borosilicate, calcium aluminum borosilicate, and aluminum.
[0108] The pigments with special effects may also be chosen from reflective particles, i.e. notably from particles whose size, structure, notably the thickness of the layer (s) of which they are made and their physical and chemical nature, and surface state, allow them to reflect incident light. This reflection may, where appropriate, have an intensity sufficient to create at the surface of the composition or of the mixture, when it is applied to the support to be made up, highlight points that are visible to the naked eye, i.e. brighter points that contrast with their environment, making them appear to sparkle.
[0109] The reflective particles may be selected so as not to significantly alter the colouring effect generated by the colouring agents with which they are combined, and more particularly so as to optimize this effect in terms of colour rendition. They may more particularly have a yellow, pink, red, bronze, orange, brown, gold and / or coppery colour or tint.
[0110] These particles may have varied forms and may notably be in platelet or globular form, in particular in spherical form.
[0111] The reflective particles, whatever their form, may or may not have a multilayer structure and, in the case of a multilayer structure, may have, for example, at least one layer of uniform thickness, notably of a reflective material.
[0112] When the reflective particles do not have a multilayer structure, they may be composed, for example, of metal oxides, notably titanium or iron oxides obtained synthetically.
[0113] When the reflective particles have a multilayer structure, they may include, for example, a natural or synthetic substrate, notably a synthetic substrate at least partially coated with at least one layer of a reflective material, notably of at least one metal or metallic material. The substrate may be made of one or more organic and / or inorganic materials.
[0114] More particularly, it may be chosen from glasses, ceramics, graphite, metal oxides, aluminas, silicas, silicates, notably aluminosilicates and borosilicates, and synthetic mica, and mixtures thereof, this list not being limiting.
[0115] The reflective material may include a layer of metal or of a metallic material.
[0116] Reflective particles are notably described in documents JP-A-09188830, JP-A-10158450, JP-A-10158541, JP-A-07258460, and JP-A-05017710.
[0117] Again as an example of reflective particles including a mineral substrate coated with a layer of metal, mention may also be made of particles including a silver-coated borosilicate substrate.
[0118] Particles with a silver-coated glass substrate, in the form of platelets, are sold under the name Microglass Metashine REFSX 2025 PS by the company Toyal. Particles with a glass substrate coated with nickel / chromium / molybdenum alloy are sold under the names Crystal Star GF 550 and GF 2525 by this same company.
[0119] Use may also be made of particles comprising a metal substrate, such as silver, aluminum, iron, chromium, nickel, molybdenum, gold, copper, zinc, tin, magnesium, steel, bronze, or titanium, said substrate being 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 oxides and mixtures thereof.
[0120] Examples that may be mentioned include aluminum powder, bronze powder, or copper powder coated with SiO2 sold under the name Visionaire by the company Eckart.
[0121] Mention may also be made of pigments with an interference effect which are not attached to a substrate, such as liquid crystals (Helicones HC from Wacker) or interference holographic glitter flakes (Geometric Pigments or Spectra f / x from Spectratek) . Pigments with special effects also comprise fluorescent pigments, whether these are substances that are fluorescent in daylight or that produce an ultraviolet fluorescence, phosphorescent pigments, photochromic pigments, thermochromic pigments, and quantum dots, sold, for example, by the company Quantum Dots Corporation.
[0122] The variety of pigments that may be used in the present invention makes it possible to obtain a wide range of colours, and also particular optical effects such as metallic effects or interference effects.
[0123] The size of the pigment used in the composition according to the present invention is generally between 10 nm and 200μm, preferably between 20 nm and 80μm, and more preferentially between 30 nm and 50μm.
[0124] The pigments may be dispersed in the composition by means of a dispersant.
[0125] The dispersant serves to protect the dispersed particles against their agglomeration or flocculation. This dispersant may be a surfactant, an oligomer, a polymer, or a mixture of several thereof, bearing one or more functionalities with a strong affinity for the surface of the particles to be dispersed. In particular, they may become physically or chemically attached to the surface of the pigments. These dispersants also contain at least one functional group that is compatible with or soluble in the continuous medium. In particular, esters of 12-hydroxystearic acid in particular and of C8 to C20 fatty acid and of polyols such as glycerol or diglycerol are used, such as poly (12-hydroxystearic acid) stearate with a molecular weight of approximately 750 g / mol, such as the product sold under the name Solsperse 21 000 by the company Avecia, polyglyceryl-2 dipolyhydroxystearate (CTFA name) sold under the reference Dehymyls PGPH by the company Henkel, or polyhydroxystearic acid such as the product sold under the reference Arlacel P100 by the company Uniqema, and mixtures thereof.
[0126] As other dispersants that may be used in the compositions of the invention, mention may be made of quaternary ammonium derivatives of polycondensed fatty acids, for instance Solsperse 17 000 sold by the company Avecia, and polydimethylsiloxane / oxypropylene mixtures such as those sold by the company Dow Corning under the references DC2-5185 and DC2-5225 C.
[0127] The pigments used in the composition may be surface-treated with an organic agent.
[0128] Thus, the pigments surface-treated beforehand that are useful in the context of the invention are pigments which have been completely or partially subjected to a surface treatment of chemical, electronic, electrochemical, mechanochemical, or mechanical nature with an organic agent, such as those described notably in Cosmetics and Toiletries, February 1990, Vol. 105, pages 53-64, before being dispersed in the composition in accordance with the invention. These organic agents may be chosen, for example, from waxes, for example carnauba wax and beeswax; fatty acids, fatty alcohols, and derivatives thereof, such as stearic acid, hydroxystearic acid, stearyl alcohol, hydroxystearyl alcohol, and lauric acid and derivatives thereof; 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; alkanolamines; silicone compounds, for example silicones, notably polydimethylsiloxanes; organofluorine compounds, for example perfluoroalkyl ethers; fluorosilicone compounds.
[0129] The surface-treated pigments that are useful in the composition may also have been treated with a mixture of these compounds and / or may have undergone several surface treatments.
[0130] The surface-treated pigments that are useful in the context of the present invention may be prepared according to surface-treatment techniques that are well known to those skilled in the art, or may be commercially available as is.
[0131] Preferably, the surface-treated pigments are coated with an organic layer.
