The present invention relates to a composition for treating keratin fibers such as the hair, comprising at least one silicone of formula (I) as described below, at least one silicone of formula (II) as described below, at least one coloring agent chosen from pigments, direct dyes and mixtures thereof and optionally at least one metallic compound.
The present invention also relates to a method for treating keratin fibers such as the hair, comprising a step of applying to the keratin fibers a composition (A) comprising at least one metallic compound; and a step of applying to the keratin fibers a composition (B) comprising at least one silicone of formula (I), and at least one silicone of formula (II), the composition (A) and/or the composition (B) comprising at least one coloring agent chosen from pigments, direct dyes and mixtures thereof.
In the field of dyeing of keratin fibers, in particular human keratin fibers, it is already known practice to dye keratin fibers via various techniques starting from direct dyes or pigments for nonpermanent dyeing or from dye precursors for permanent dyeing.
There are essentially three types of process for dyeing the hair:
For this last type of dyeing, it is known practice to use colored polymers formed by grafting one or more dyes of azo, triphenylmethane, azine, indoamine or anthraquinone nature to a polymer chain. These colored polymers are not entirely satisfactory, in particular as regards the homogeneity of the coloring obtained and its resistance, not to mention the problems associated with their manufacture and in particular with their reproducibility.
Another dyeing method consists in using pigments. Specifically, the use of pigment on the surface of keratin fibers generally makes it possible to obtain visible colorings on dark hair, since the surface pigment masks the natural color of the fiber. However, the colorings obtained via this dyeing method have the drawback of having poor resistance to shampoo washing and also to external agents such as sebum, perspiration, brushing and/or rubbing.
In addition, there are no effective makeup-removing compositions for removing this type of temporary dye composition when it is persistent with respect to shampoo washing.
Furthermore, such a pigment-based dye may require the application of high heat and/or the application of heat over a prolonged time to the keratin fibers in order to accelerate the formation of the colored coating on the keratin fibers and to improve the persistence of the colored coating with respect to shampoo washing and to external agents.
However, this requires the use of a particular heating tool which makes the application of the composition on the keratin fibers more complex.
The need thus remains to have available a composition for treating keratin fibers, in particular the hair, which exhibits the advantage of obtaining a homogeneous and smooth colored coating on the hairs, while forming a covering which is persistent toward shampooing operations and to the various attacking factors to which the hair may be subjected, such as brushing and/or rubbing actions, without degrading the hair and without applying excessive heat. There is also the need to be able to eliminate this colored coating when so desired.
The applicant has discovered, surprisingly, that all of these objectives can be achieved by means of the composition according to the present invention.
The present invention relates to a composition for treating keratin fibers such as the hair, comprising:
The present invention also relates to a method for treating, in particular for dyeing, keratin fibers, such as the hair, wherein the composition according to the invention as described below is applied to said fibers.
The present invention also relates to the use of the composition as described below for treating keratin fibers such as the hair, in particular for dyeing keratin fibers such as the hair.
The present invention also relates to a method for treating keratin fibers such as the hair, comprising:
Through the use of this composition, colored coatings are obtained on the hair that make it possible to obtain a coloring that is visible on all types of hair in a manner that is persistent with respect to shampoo washing, while at the same time preserving the physical qualities of the keratin fibers. Such a coating may be resistant to the external attacking factors to which the hair may be subjected, such as blow-drying and perspiration. It makes it possible in particular to obtain a smooth and uniform deposit on the keratin fibers.
Furthermore, such a composition does not require the application of excessive heat to the keratin fibers.
Advantageously, the colored coating thus obtained can be readily eliminated by means of a makeup-removing composition.
For the purposes of the present invention, the expression “coloring that is persistent with respect to shampoo washing” is understood to mean that the coloring obtained persists after one shampoo wash, preferably after three shampoo washes.

The expression “at least one” means one or more.
The expression “keratin fibers” is understood particularly to mean human keratin fibers, such as the hair, eyelashes, eyebrows and body hair, preferentially the hair, eyebrows and eyelashes, more preferentially still the hair.
For the purposes of the present invention, the expression “hair” means the hair of the head. It does not refer to eyelashes, eyebrows and body hair.
For the purposes of the present invention, the expression “successive steps” is understood to mean steps performed in the indicated order.
For the purposes of the present invention, the term “silicone” denotes any organosilicon polymer or oligomer of linear or cyclic, branched or crosslinked structure, of variable molecular weight, obtained by polymerization and/or by polycondensation of suitably functionalized silanes, and constituted essentially of a repetition of main units in which the silicon atoms are linked together via oxygen atoms (siloxane bond —Si—O—Si—), optionally substituted hydrocarbon-based radicals being directly bonded via a carbon atom to said silicon atoms.

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).
The pigment may also be a special effect pigment. The term “special effect pigments” means pigments that generally create a colored 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 colored pigments, which afford a standard uniform opaque, semi-transparent or transparent shade.
Several types of special effect pigments exist: those with a low refractive index, such as fluorescent or photochromic pigments, and those with a higher refractive index, such as pearlescent agents, interference pigments or glitter flakes.
Examples of special effect pigments that may be mentioned include pearlescent pigments such as mica covered with titanium or with bismuth oxychloride, colored pearlescent 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 pearlescent pigments based on bismuth oxychloride. Mention may be made, as pearlescent pigments, of the pearlescent agents Cellini sold by BASF (mica-TiO2-lake), Prestige sold by Eckart (mica-TiO2), Prestige Bronze sold by Eckart (mica-Fe2O3) or Colorona sold by Merck (mica-TiO2—Fe2O3).
Mention may also be made of the gold-colored pearlescent agents 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 pearlescent agents 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 pearlescent agents 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 pearlescent agents sold notably by the company BASF under the name Nu-antique copper 340XB (Cloisonne) and Brown CL4509 (Chromalite); the pearlescent agents with a copper glint sold notably by the company BASF under the name Copper 340A (Timica); the pearlescent agents with a red glint sold notably by the company Merck under the name Sienna fine (17386) (Colorona); the pearlescent agents with a yellow glint sold notably by the company BASF under the name Yellow (4502) (Chromalite); the red pearlescent agents with a gold glint sold notably by the company BASF under the name Sunstone G012 (Gemtone); the pink pearlescent agents sold notably by the company BASF under the name Tan opal G005 (Gemtone); the black pearlescent agents with a gold glint sold notably by the company BASF under the name Nu antique bronze 240 AB (Timica), the blue pearlescent agents sold notably by the company Merck under the name Matte blue (17433) (Microna), the white pearlescent agents with a silvery glint sold notably by the company Merck under the name Xirona Silver, and the golden-green pink-orange pearlescent agents sold notably by the company Merck under the name Indian summer (Xirona), and mixtures thereof.
Still as examples of pearlescent agents, mention may also be made of particles including a borosilicate substrate coated with titanium oxide.
Particles comprising a glass substrate coated with titanium oxide are notably sold under the name Metashine MC1080RY by the company Toyal.
Finally, examples of pearlescent agents that may also be mentioned include polyethylene terephthalate glitter flakes, notably those sold by Meadowbrook Inventions under the name Silver 1P 0.004X0.004 (silvery 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. The special effect pigments 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. The reflective particles may be selected so as not to significantly alter 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 rendition. They may more particularly have a yellow, pink, red, bronze, orange, brown, gold and/or coppery color or glint.
These particles may have varied forms and may notably be in platelet or globular form, in particular in spherical form.
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.
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. 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. 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.
The reflective material may include a layer of metal or of a metallic material.
Reflective particles are notably described in documents JP-A-09188830, JP-A-10158450, JP-A-10158541, JP-A-07258460 and JP-A-05017710.
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.
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.
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.
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.
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). Special effect pigments also comprise fluorescent pigments, whether these are substances which are fluorescent in daylight or which produce an ultraviolet fluorescence, phosphorescent pigments, photochromic pigments, thermochromic pigments and quantum dots, for example sold by Quantum Dots Corporation.
The variety of the pigments that may be used in the present invention makes it possible to obtain a rich palette of colors and also specific optical effects, such as metallic effects or interference effects.
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 preferentially between 30 nm and 50 μm.
The pigments may be dispersed in the composition by means of a dispersant.
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 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 Avecia, polyglyceryl-2 dipolyhydroxystearate (CTFA name) sold under the reference Dehymyls PGPH by Henkel, or else polyhydroxystearic acid such as the product sold under the reference Arlacel P100 by Uniqema, and mixtures thereof.
