Description

Title of the invention: COMPOSITION AND PROCESS FOR DYEING KERATINOUS FIBERS Technical field

[0001] The present invention relates to a composition. In particular, the present invention relates to a composition for dyeing keratinous fibers such as hair. The present invention also relates to a process for dyeing keratinous fibers such as hair. STATE OF THE ART

[0002] Many people have long been looking for ways to change their hair color, especially to hide gray hair.

[0003] In the field of dyeing keratinous fibers, in particular human keratinous fibers, it is already known to dye hair keratinous fibers via various techniques using direct dyes or pigments for non-permanent dyeing, or dye precursors for permanent dyeing.

[0004] There are basically three types of hair dyeing processes: a. “permanent” dyeing, the function of which is to make a substantial change to the natural color and which uses oxidation dyes which penetrate the hair fibers and form the dye by a process of oxidative condensation; 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; c. temporary dyeing, which results in a change in the natural hair color that remains from one shampoo to the next, and which serves to enhance or correct an already obtained shade. It can also be likened to a “makeup” process.

[0005] The temporary dyeing process involves the use of pigments. Specifically, the use of pigments on the surface of keratinous fibers generally makes it possible to obtain visible colorations on dark hair, because the surface pigment masks the natural color of the fibers.

[0006] Temporary hair dyeing and / or makeup compositions may result in a non-cosmetic and / or unnatural hair feel; in particular, hair so dyed may lack softness and / or suppleness and / or strand separation.

[0007] Thus, there is a need to develop a composition for dyeing keratinous fibers such as hair which has the advantage of having good cosmetic properties for the hair such as softness and suppleness while maintaining hair with good separation of the strands. Summary of the invention

[0008] An objective of the present application is to provide a composition for dyeing keratinous fibers such as hair, which has good cosmetic properties for the hair such as softness and suppleness while maintaining hair with good separation of the strands.

[0009] Another objective of the present application is to provide a process for dyeing keratinous fibers such as hair.

[0010] Thus, the present invention provides a composition, preferably for dyeing keratinous fibers such as hair, comprising: a. at least one protein with a molecular weight of at least 10 kDa; b. at least one cationic surfactant chosen from a tertiary amidoamine; and c. at least one coloring agent chosen from pigments, direct dyes and their mixtures.

[0011] Preferably, the composition according to the present invention is a composition for dyeing keratinous fibers such as hair.

[0012] The present invention also relates to a process for dyeing keratinous fibers such as hair comprising applying the composition as described above to the keratinous fibers such as hair.

[0013] The inventors have discovered that the composition according to the present invention makes it possible to obtain colored hair which has good separation of the strands and a smoother feel, is softer and more supple and easy to detangle.

[0014] Other subjects and characteristics, aspects and advantages of the present invention will become even more apparent upon reading the detailed description and examples which follow. DETAILED DESCRIPTION OF THE INVENTION

These pigments composites may be composed in particular of particles including an inorganic core, at least one binder for fixing the organic pigments to the core, and at least one organic pigment which at least partially covers the core.

[0080] The organic pigment may also be a lake. The term "lake" designates dyes adsorbed on insoluble particles, the whole thus obtained remaining insoluble during use.

[0081] The mineral substrates on which the dyes are adsorbed are, for example, alumina, silica, calcium-sodium borosilicate or calcium-aluminum and aluminum borosilicate.

[0082] Among the dyes, we can cite carminic acid. Other dyes known as: D&C Red 21 (CI 45380), D&C Orange 5 (CI 45370), D&C Red 27 (CI 45410), D&C Orange 10 (CI 45425), D&C Red 3 (CI 45430), D&C Red 4 (CI 15510), D&C Red 33 (CI 17200), D&C Yellow 5 (CI 19140), D&C Yellow 6 (CI 15985), D&C Green 5 (CI 61570), D&C Yellow 10 (CI 77002), D&C Green 3 (CI 42053), D&C Blue 1 (CI 42090).

[0083] An example of a lake that can be cited is the product known under the following name: D&C Red 7 (CI 15 850:1).

[0084] The pigment may also be a special effect pigment. The term "special effect pigments" refers to pigments that generally create a colored appearance (characterized by a certain hue, vibrancy, and luminance level) that is non-uniform and changes depending on viewing conditions (light, temperature, viewing angles, etc.). They are thus distinguished from colored pigments that provide a standard uniform opaque, semi-transparent, or transparent shade.

[0085] 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 pearlescent pigments, interference pigments or glitter flakes.

[0086] Examples of special effect pigments that may be cited 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 oxide, mica coated with titanium and in particular ferric blue or chromium oxide, mica coated with titanium and an organic pigment as defined above, as well as pearlescent pigments based on bismuth oxychloride. Pearlescent pigments that may be cited include Cellini pearlescent pigments sold by BASF (mica-TiO2 lake), Prestige pearlescent pigments sold by Eckart (mica-TiO2), Prestige Bronze pearlescent pigments sold by Eckart (mica-Fe2O3) and Colorona pearlescent pigments sold by Merck (mica-TiO2-Fe2O3).

[0087] We can also cite the golden mother-of-pearl sold in particular by the company BASF under the names Brillant gold 212G (Timica), Gold 222C (Cloisonne), Sparkle gold (Timica), Gold 4504 (Chromalite) and Monarch gold 233X (Cloisonne); bronze mother-of-pearl sold in particular 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 sold in particular 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 mother-of-pearl sold in particular by BASF under the names Nu-antique copper 340XB (Cloisonne) and Brown CL4509 (Chromalite); copper-tinted mother-of-pearl sold in particular by BASF under the name Copper 340A (Timica), red-tinted mother-of-pearl sold in particular by Merck under the name Sienna fine (17386)(Colorona);yellow-tinted mother-of-pearl sold in particular by BASF under the name Yellow (4502) (Chromalite); red mother-of-pearl with a golden tint sold in particular by BASF under the name Sunstone G012 (Gemtone); pink mother-of-pearl sold in particular by BASF under the name Tan opale G005 (Gemtone); black mother-of-pearl with a golden tint sold in particular by BASF under the name Nu antique bronze 240 AB (Timica), blue mother-of-pearl sold in particular by Merck under the name Matte blue (17433) (Microna), white mother-of-pearl with a silver tint sold in particular by Merck under the name Xirona Silver and green-gold and pink-orange mother-of-pearl sold in particular by Merck under the name Indian summer (Xirona), and mixtures thereof. ;

[0088] Still as examples of pearlescent agents, we can also cite particles including a borosilicate substrate coated with titanium oxide.

[0089] The particles comprising a glass substrate coated with titanium oxide are notably sold under the name Metashine MC1080RY by the company Toyal.

[0090] Finally, examples of nacres which may also be cited include polyethylene terephthalate glitter flakes, in particular those sold by the company Mea-dowbrook Inventions under the name Silver IP 0.004X0.004 (silver glitter flakes). It is also possible to envisage multi-layer pigments based on synthetic substrates, such as alumina, silica, calcium-sodium borosilicate, calcium-aluminum borosilicate and aluminum.

[0091] The special effect pigments may also be chosen from reflective particles, that is to say in particular particles whose size, structure, in particular the thickness of the layer(s) of which they are composed as well as their physical and chemical nature and their surface state, 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 it is applied to the support to be made up, highlights visible to the naked eye, that is to say brighter points that contrast with their surroundings and appear to sparkle.

[0092] The reflective particles may be chosen so as not to significantly modify the coloring effect generated by the coloring agents with which they are combined, and more particularly so as to optimize this effect in terms of color rendering. They may more particularly have a yellow, pink, red, bronze, orange, brown, gold and / or copper color or tint.

[0093] These particles can have various shapes and can in particular be in platelet or globular form, in particular in spherical form.

[0094] The reflective particles, whatever their shape, may or may not have a multi-layer structure and, in the case of a multi-layer structure, may have, for example, at least one layer of uniform thickness, in particular of a reflective material.

[0095] When the reflective particles do not have a multilayer structure, they may be composed, for example, of metal oxides, in particular synthetically obtained titanium or iron oxides.

[0096] When the reflective particles have a multi-layer structure, they may include, for example, a natural or synthetic substrate, in particular a synthetic substrate at least partially coated with at least one layer of a reflective material, in particular at least one metal or metallic material. The substrate may consist of one or more organic and / or inorganic materials.

[0097] More particularly, it can be chosen from glasses, ceramics, graphite, metal oxides, aluminas, silicas, silicates, in particular aluminosilicates and borosilicates, and synthetic mica, and mixtures thereof, this list not being exhaustive.

[0098] The reflective material may include a layer of metal or metallic material.

[0099] The reflective particles are described in particular in documents JP-A-09188830, JP-A-10158450, JP-A-10158541, JP-A-07258460 and JP-A-05017710.

[0100] As another example of reflective particles including a mineral substrate coated with a layer of metal, mention may also be made of particles including a borosilicate substrate coated with silver.

[0101] The 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. The particles with a nickel / chromium / molybdenum alloy-coated glass substrate are sold under the names Crystal Star GF 550 and GF 2525 by the same company.

[0102] Particles comprising a metallic substrate such as silver, aluminum, iron, chromium, nickel, molybdenum, gold, copper, zinc, tin, magnesium, steel, bronze or titanium may also be used, said substrate being coated with at least one of the following: 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.

[0103] Examples that may be cited include aluminum powder, bronze powder or SiO2 coated copper powder sold under the name Visionaire by the company Eckart.

[0104] Also included are interference effect pigments that are not fixed to a substrate, such as liquid crystals (Helicones HC from Wacker) and holographic interference glitter flakes (Geometry Pigments or Spectra f / x from Spectratek). Special effect pigments also include fluorescent pigments, whether substances that fluoresce in daylight or produce ultraviolet fluorescence, phosphorescent pigments, photochromic pigments, thermochromic pigments, and quantum dots, sold, for example, by Quantum Dots Corporation.

[0105] The variety of pigments that can be used in the present invention makes it possible to obtain a wide range of colors, as well as particular optical effects such as metallic effects or interference effects.

[0106] The size of the pigment used in the composition according to the present invention is generally between 10 nm and 200 pm, preferably between 20 nm and 80 pm, and more preferably between 30 nm and 50 pm.

[0107] The pigments may be dispersed in the composition by means of a dispersant.

[0108] The dispersing agent 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 of these, carrying one or more functionalities with a strong affinity for the surface of the particles to be dispersed. In particular, they may attach physically or chemically to the surface of the pigments. These dispersants also contain at least one functional group which is compatible with the continuous medium or soluble therein.In particular, esters of 12-hydroxy stearic acid in particular and of C8 to C20 fatty acid and 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.

[0109] As other dispersants which can be used in the compositions of the invention, mention may be made of quaternary ammonium derivatives of polycondensed fatty acids, for example Solsperse 17 000 sold by the company Avecia, and mixtures polydimethylsiloxane / oxypropylene such as those sold by Dow Corning under the references DC2-5185 and DC2-5225 C.

[0110] The pigments used in the composition may be surface treated with an organic agent.

[0111] Thus, the pre-surface-treated pigments which are useful in the context of the invention are pigments which have been entirely or partially subjected to a surface treatment of a chemical, electronic, electrochemical, mechano-chemical or mechanical nature with an organic agent, such as those described in particular in Cosmetics and Toiletries, February 1990, Vol. 105, pages 53 to 64, before being dispersed in the composition in accordance with the invention.These organic agents may be chosen, for example, from waxes, for example camauba 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; 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, in particular polydimethylsiloxanes; organofluorine compounds, for example perfluoroalkyl ethers; fluorosilicone compounds.

[0112] 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.

[0113] Surface-treated pigments that are useful in the context of the present invention may be prepared according to surface treatment techniques well known to those skilled in the art, or may be commercially available as is.

[0114] Preferably, the surface-treated pigments are coated with an organic layer.

[0115] The organic agent with which the pigments are treated may be deposited on the pigments by solvent evaporation, chemical reaction between the surfactant molecules or creation of a covalent bond between the surfactant and the pigments.

[0116] The surface treatment can thus be carried out, for example, by chemical reaction of a surfactant with the surface of the pigments and 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.
