Description

Composition comprising at least one alkoxysilane of formula (I), at least one non amino silicone of formula (II) and at least one coloring agent

[0001] The present invention relates to a composition for treating keratin fibers such as the hair, comprising at least one alkoxysilane chosen from the compounds of formula (I), at least one non amino silicone of formula (II) and at least one coloring agent chosen from pigments, direct dyes and mixtures thereof.

Technical field

[0002] In the field of the 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.

[0003] There are essentially three types of process for dyeing the hair:

[0004] a) "permanent" dyeing, the function of which is to afford a substantial modification to the natural color and which employs oxidation dyes which penetrate into the hair fiber and forms the dye via an oxidative condensation process;

[0005] b) nonpermanent, semipermanent or direct dyeing, which does not employ the oxidative condensation process and withstands four or five shampoo washes; it consists in dyeing keratin fibers with dye compositions containing direct dyes;

[0006] c) temporary dyeing, which gives rise to a modification to the natural color of the head of hair which remains from one shampooing operation to the next, and which serves to enhance or correct a shade which has already been obtained. It can also be likened to a "makeup" process.

[0007] 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.

[0008] Another dyeing method consists in using pigments. Specifically, the use of pigment at 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 exhibit the disadvantage of having poor resistance to shampooing operations and also to external agents, such as sebum, perspiration, brushing and/or rubbing actions.

[0009] 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.

[0010] 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. There is also a need to be able to eliminate this colored coating when so desired.

[0011] Thus, the aim of the present invention is to develop 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 coating 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. Advantageously, the colored coating can be readily removed when so desired.

Disclosure of the invention

[0012] The present invention relates to a composition for treating keratin fibers such as the hair, comprising: a) at least one alkoxysilane chosen from the compounds of formula (I) as described below, oligomers thereof and/or mixtures thereof; b) at least one non amino silicone of formula (II) as described below; and c) at least one coloring agent chosen from pigments, direct dyes and mixtures thereof.

[0013] The present invention also relates to a process for the cosmetic treatment, in particular the dyeing, of keratin fibers such as the hair, wherein the composition as described below is applied to said fibers.

[0014] The present invention also relates to the use of composition as described below for the cosmetic treatment of, in particular for dyeing, keratin fibers such as the hair.

[0015] 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.

[0016] For the purposes of the present invention, " coloring which is persistent with regard to shampooing operations " is understood to mean that the coloring obtained persists after one shampooing operation, preferably after three shampooing operations, more preferentially after five shampooing operations.

[0017] Advantageously, the colored coating thus obtained can be readily eliminated by means of a makeup-removing composition.

Special effect pigments is understood to mean pigments which create in a general way a colored appearance (characterized by a certain shade, a certain vividness and a certain brightness) which is nonuniform and which changes as a function of the conditions of observation (light, temperature, angles of observation, and the like). They thereby contrast with colored pigments, which provide a conventional uniform opaque, semitransparent or transparent shade.

[0076] Several types of special effect pigments exist: those having a low refractive index, such as fluorescent or photochromic pigments, and those having a higher refractive index, such as pearlescent agents, interference pigments or glitters.

[0077] Mention may be made, as examples of special effect pigments, of pearlescent pigments, such as mica coated 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 in particular with ferric blue or with chromium oxide, mica covered with titanium and with an organic pigment as defined above, and also pearlescent pigments based on bismuth oxychloride.

[0081] Finally, mention may also be made, as examples of pearlescent agents, of polyethylene terephthalate glitter, in particular that sold by Meadowbrook Inventions under the name Silver IP 0.004X0.004 (silver glitter). It is also possible to envisage multilayer pigments based on synthetic substrates, such as alumina, silica, calcium sodium borosilicate or calcium aluminum borosilicate and aluminum.

[0082] The special effect pigments can also be chosen from reflective particles, that is to say in particular particles having a size, a structure, in particular a thickness of the layer or layers of which it is composed and their physical and chemical nature, and the surface condition which allow them to reflect incident light. This reflection may, if appropriate, have an intensity sufficient to create, at the surface of the composition or of the mixture, when the latter is applied to the support to be made up, highlight points visible to the naked eye, that is to say more luminous points which contrast with their environment by appearing to sparkle.

[0083] The reflective particles can be selected so as not to detrimentally affect, to a significant extent, the coloring effect generated by the coloring agents which are combined with them and more particularly so as to optimize this effect in terms of color rendition. They can more particularly have a yellow, pink, red, bronze, orangey, brown, gold and/or coppery color or glint.

[0084] These particles can exhibit varied forms and can in particular be in the platelet or globular form, especially the spherical form.

[0085] The reflective particles, whatever their form, may or may not exhibit a multilayer structure and, in the case of a multilayer structure, may exhibit, for example, at least one layer of uniform thickness, in particular of a reflective material.

[0086] When the reflective particles do not exhibit a multilayer structure, they can be composed, for example, of metal oxides, in particular of titanium or iron oxides obtained synthetically.

[0087] When the reflective particles exhibit a multilayer structure, they can, for example, comprise 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 of at least one metal or metal material. The substrate can be made of one or more organic and/or inorganic materials.

[0088] More particularly, it can be chosen from glasses, ceramics, graphite, metal oxides, aluminas, silicas, silicates, in particular aluminosilicates and borosilicates, synthetic mica and mixtures thereof, this list not being limiting.

[0089] The reflective material can comprise a layer of metal or of a metal material. [0090] Reflective particles are described in particular in the documents JP-A-09188830, JP- A-10158450, JP-A-10158541, JP-A-07258460 and JP-A-05017710.

[0091] Mention may also be made, still by way of example of reflective particles comprising an inorganic substrate coated with a layer of metal, of the particles comprising a borosilicate substrate coated with silver.

[0092] Particles comprising a glass substrate coated with silver, in the form of platelets, are sold under the name Microglass Metashine REFSX 2025 PS by Toyal. Particles comprising 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.

[0093] 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.

[0094] Mention may be made, by way of examples, of aluminum powder, bronze powder or copper powder coated with SiCk sold under the name Visionaire by Eckart.

[0095] 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 (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.

[0096] The variety of the pigments which can 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.

[0097] 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 preferentially between 30 nm and 50 pm.

[0098] The pigments can be dispersed in the composition by virtue of a dispersing agent. [0099] The dispersing agent serves to protect the dispersed particles from the agglomeration or flocculation thereof. This dispersing agent can be a surfactant, an oligomer, a polymer or a mixture of several of them carrying one or more functionalities having a strong affinity for the surface of the particles to be dispersed. In particular, they can become attached physically or chemically to the surface of the pigments. These dispersants additionally exhibit at least one functional group compatible with or soluble in the continuous medium. Use is made in particular of esters of 12-hydroxy stearic acid, in particular, and of Cx to C20 fatty acid and of polyol, for instance glycerol or diglycerol, such as poly( 12-hydroxy stearic acid) stearate with a molecular weight of approximately 750 g/mol, such as that sold under the name of Solsperse 21 000 by Avecia, polyglyceryl-2 dipolyhydroxystearate (CTFA name), sold under the reference Dehymyls PGPH by Henkel, or polyhydroxystearic acid, such as that sold under the reference Arlacel PI 00 by Uniqema, and mixtures thereof.

[00100] Mention may be made, as other dispersant which can be used in the compositions of the invention, of the quaternary ammonium derivative of polycondensed fatty acids, such as Solsperse 17 000, sold by Avecia, and polydimethylsiloxane/oxypropylene mixtures, such as those sold by Dow Corning under the references DC2-5185 and DC2-5225 C.

[00101] The pigments used in the composition can be surface-treated with an organic agent.

[00102] Thus, the pigments surface-treated beforehand of use 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 which are described in particular 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 can, for example, be chosen from waxes, for example 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; 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; or fluorosilicone compounds.

[00103] The surface-treated pigments of use in the composition may also have been treated with a mixture of these compounds and/or may have undergone several surface treatments.

[00104] The surface-treated pigments of use in the context of the present invention can be prepared according to surface treatment techniques well known to those skilled in the art or found as such commercially.

[00105] Preferably, the surface-treated pigments are covered with an organic layer.

[00106] The organic agent with which the pigments are treated can be deposited on the pigments by evaporation of solvent, chemical reaction between the molecules of the surface agent or creation of a covalent bond between the surface agent and the pigments.

[00107] The surface treatment can thus be carried out, for example, by chemical reaction of a surface agent with the surface of the pigments and creation of a covalent bond between the surface agent and the pigments or fillers. This method is described in particular in the patent US 4 578 266.

[00108] Preferably, use will be made of an organic agent covalently bonded to the pigments.

[00109] The agent for the surface treatment can represent from 0.1% to 50% by weight of the total weight of the surface-treated pigment, preferably from 0.5% to 30% by weight and more preferentially still from 1% to 20% by weight of the total weight of the surface-treated pigment.

[00110] Preferably, the surface treatments of the pigments are chosen from the following treatments:

- a PEG-silicone treatment, for instance the AQ surface treatment sold by LCW;

- a methicone treatment, for instance the SI surface treatment sold by LCW;

- a dimethicone treatment, for instance the Covasil 3.05 surface treatment sold by LCW;

- a dimethicone/trimethyl siloxysilicate treatment, for instance the Covasil 4.05 surface treatment sold by LCW;

- a magnesium myristate treatment, for instance the MM surface treatment sold by LCW; - an aluminum dimyri state treatment, such as the MI surface treatment sold by Miyoshi;

- a perfluoropolymethylisopropyl ether treatment, for instance the FHC surface treatment sold by LCW;

- an isostearyl sebacate treatment, for instance the HS surface treatment sold by Miyoshi;

- a perfluoroalkyl phosphate treatment, for instance the PF surface treatment sold by Daito;

- an acrylate/dimethicone copolymer and perfluoroalkyl phosphate treatment, for instance the FSA surface treatment sold by Daito;

- a polymethylhydrogenosiloxane/perfluoroalkyl phosphate treatment, for instance the FS01 surface treatment sold by Daito;

- an acrylate/dimethicone copolymer treatment, for instance the ASC surface treatment sold by Daito;

- an isopropyl titanium triisostearate treatment, for instance the ITT surface treatment sold by Daito;

- an acrylate copolymer treatment, for instance the APD surface treatment sold by Daito;

- a perfluoroalkyl phosphate/isopropyl titanium triisostearate treatment, for instance the PF + ITT surface treatment sold by Daito.

[00111] According to a specific embodiment of the invention, the dispersing agent is present with organic or inorganic pigments in particulate form of submicronic size in the dye composition.

[00112] "Submicronic" is understood to mean pigments, the particle size of which has been micronized by a micronization method and the mean particle size of which is less than a micrometer (pm), in particular between 0.1 and 0.9 pm, and preferably between 0.2 and 0.6 pm.

[00114] The dispersing agent(s) can thus have a silicone backbone, such as silicone polyether and dispersing agents of aminosilicone type other than the alkoxysilanes described above. Mention may be made, among the suitable dispersing agents, of: - amino silicones, i.e. silicones comprising one or more amino groups such as those sold under the names and references: BYK LPX 21879 by BYK, GP-4, GP-6, GP-344, GP-851, GP-965, GP-967 and GP-988-1, sold by Genesee Polymers,

[00115] According to a specific embodiment, the dispersing agent(s) are of aminosilicone type, other than the alkoxysilanes described above, and are cationic.

[00116] Preferably, the pigment(s) is (are) chosen from mineral, mixed mineral-organic or organic pigments.

[00117] In one variant of the invention, the pigment(s) according to the invention are organic pigments, preferentially organic pigments surface-treated with an organic agent chosen from silicone compounds. In another variant of the invention, the pigment(s) according to the invention are mineral pigments.

[00204] Process for treating keratin fibers [00205] The present invention also relates to a process for the cosmetic treatment, in particular the dyeing, of keratin fibers such as the hair, wherein the composition as described above is applied to said fibers.

[00206] Preferably, the composition according to the invention is a composition for dyeing keratin fibers, such as the hair.

[00207] The composition according to the invention can be used on wet or dry keratin fibers, and also on all types of fair or dark, natural or dyed, permanent-waved, bleached or relaxed, fibers.

[00208] According to a specific embodiment of the process of the invention, the fibers are washed before application of the composition described above.

[00209] The application of the dye composition to the keratin fibers can be carried out by any conventional means, in particular by means of a comb, a fine brush, a coarse brush or with the fingers.

[00210] The dyeing process, i.e. application of the dye composition to the keratin fibers, is generally carried out at ambient temperature (between 15°C and 25°C).

[00211] After application of the composition, the fibers may be left to dry or may be dried, for example at a temperature of greater than or equal to 30°C.

[00212] The process according to the invention may comprise a step of applying heat to the keratin fibers using a heating tool.

[00213] Preferably, after application of the composition according to the invention to the keratin fibers, there is a waiting time of at least 30 seconds, preferably of at least 1 minute and more preferentially of at least 5 minutes, before the step of applying heat to the keratin fibers.

[00214] The heat application step of the process of the invention can be carried out using a hood, a hairdryer, a straightening iron, a curling iron, a climazon, and the like.

[00215] Preferably, the heat application step of the process of the invention is carried out using a hairdryer and/or a straightening iron.

[00216] When the process of the invention involves a step of applying heat to the keratin fibers, the step of applying heat to the keratin fibers takes place after the application of the composition to the keratin fibers. [00217] During the step of applying heat to the keratin fibers, a mechanical action may be exerted on the locks, such as combing, brushing or running the fingers through.

[00218] When the step of applying heat to the keratin fibers is performed using a hood or a hairdryer, the temperature is preferably between 30°C and 110°C, preferentially between 50°C and 90°C.

[00219] When the step of applying heat to the keratin fibers is performed using a straightening iron, the temperature is preferably between 110°C and 220°C, preferably between 140°C and 200°C.

[00220] In a specific variant, the process of the invention employs a step (bl) of applying heat using a hood, a hairdryer or a climazon, preferably a hairdryer, and a step (b2) of applying heat using a straightening or curling iron, preferably a straightening iron.

[00221] Step (bl) can be carried out before step (b2).

[00222] During step (bl), also referred to as the drying step, the fibers may be dried, for example at a temperature above or equal to 30°C. According to one particular embodiment, this temperature is above 40°C. According to a particular embodiment, this temperature is above 45°C and below 110°C.

[00223] Preferably, if the fibers are dried, they are dried, in addition to a supply of heat, with a flow of air. This flow of air during the drying makes it possible to improve the individualization of the coating.

[00224] During the drying, a mechanical action may be exerted on the locks, such as combing, brushing or running the fingers through.

[00225] During step (b2), the passage of the straightening or curling iron, preferably the straightening iron, can be carried out at a temperature ranging from 110°C to 220°C, preferably between 140°C and 200°C.

[00226] Preferably, after application of the composition according to the invention to the keratin fibers and after optionally a step of applying heat to the keratin fibers, there is a waiting time of at least 30 minutes before the first shampooing operation, preferably at least 1 h before the first shampooing operation, more preferentially at least 10 h before the first shampooing operation, better still at least 24 h before the first shampooing operation.

[00227] The present invention also relates to a process for treating keratin fibers such as the hair, comprising the following steps: a) applying to the keratin fibers a composition as defined above, and b) applying to the dyed keratin fibers a makeup-removing composition preferably comprising at least one hydrocarbon-based oil.

[00228] The present invention also relates to a kit for treating keratin fibers such as the hair, comprising a composition as defined above, and a makeup-removing composition comprising at least one hydrocarbon-based oil.

[00229] Thus, the process according to the invention may comprise a step of applying a makeup-removing composition to dyed keratin fibers such as the hair. This step may take place following the dyeing of the keratin fibers by the dye composition according to the invention after the optional step of applying heat to the keratin fibers, or after a defined time, i.e. days or weeks, after the application of the dye composition to the keratin fibers and the optional step of applying heat to the keratin fibers.

[00230] The makeup-removing composition may correspond to a makeup-removing composition conventionally used in cosmetics. Preferably, the makeup-removing composition comprises at least one hydrocarbon-based oil.

[00231] Preferably, the hydrocarbon-based oil(s) are chosen from synthetic esters of formula R1COOR2 wherein Ri represents a fatty acid residue including from 8 to 29 carbon atoms, and R2 represents a branched or unbranched hydrocarbon-based chain containing from 3 to 30 carbon atoms, and mixtures thereof, more preferentially from isopropyl myristate, isononyl isononanoate and/or mixtures thereof.

[00232] Preferably, the application of the dye composition to the keratin fibers such as the hair is carried out before the application of the makeup-removing composition.

[00233] The step of applying heat to the keratin fibers may be performed after the application of the dye composition and before the application of the makeup-removing composition to the keratin fibers.

[00234] The application of the makeup-removing composition may be performed on dry dyed keratin fibers or wet dyed keratin fibers and also on all types of fibers.

[00235] The makeup-removing process is generally performed at ambient temperature (between 15°C and 25°C).

[00236] The application of the makeup-removing composition may be performed immediately after the application of the dye composition (i.e. a few minutes to a few hours after the application of the dye composition), or in the days or weeks following the application of the dye composition.

[00237] The makeup-removing composition may be applied with the aid of any suitable support, which is in particular capable of absorbing it, for example a fibrous makeup- removing disk, for example a woven or nonwoven fabric, cotton wool, a flocked film, a sponge, a wipe, or a twisted or injection- molded mascara application brush.

[00238] The makeup-removing composition may be contained in a container and taken up gradually each time makeup is removed. As a variant, the makeup-removing composition impregnates the support used for makeup removal, the support possibly being packaged, in this case, for example in leaktight packaging.

[00239] After the makeup-removing composition has been used, it is possible for the keratin fibers not to be rinsed. As a variant, they may be rinsed. The rinsing may be performed, for example, with running water, without addition of a soap.

[00240] The present invention also relates to the use of the composition as described above, for the cosmetic treatment, in particular the dyeing, of keratin fibers, in particular keratin fibers such as the hair.

[00241] The present invention will now be described more specifically by means of examples, which do not in any way limit the scope of the invention. However, the examples make it possible to support preferred embodiments, variants and specific characteristics of the invention.

Example:

[00242] In the examples, the temperature is given in degrees Celsius and corresponds to ambient temperature (20-25°C), unless otherwise indicated, and the pressure is atmospheric pressure, unless otherwise indicated.

[00243] The following compositions are prepared (in g/100 g, AM: Active material): [00244] [Table 1]

[00245] Protocol:

[00246] The composition A is applied to locks of dry natural hair having 90% white hairs, in a proportion of 1 g of composition per gram of lock.

[00247] The locks of hair are left at ambient temperature for 5 min.

[00248] The locks of hair are subsequently combed and dried with a hairdryer for 3 minutes.

[00249] The locks of hair are left at ambient temperature for 24 hours. [00250] The locks of hair thus dyed are then subjected to a test of several repeated shampoo washes so as to evaluate the fastness (persistence) of the coloring obtained with respect to shampoo washes, according to the shampoo wash protocol described below.

[00251] Protocol of the shampooing operation:

[00252] The locks are washed using a standard shampoo (Gamier Ultra Doux).

[00253] The locks of hair are subsequently rinsed, combed and dried with a hairdryer.

[00254] The following shampooing operation is carried out on the locks obtained after the application of the hairdryer.

[00255] Results:

[00256] The persistence of the color of the locks was evaluated in the CIE L*a*b* system, using a Minolta Spectrophotometer CM3600A colorimeter (illuminant D65, angle 10°, specular component included).

[00257] In this L*a*b* system, L* represents the intensity of the color, a* indicates the green/red color axis and b* indicates the blue/yellow color axis.

[00258] The persistence of the coloring is evaluated by the color difference DE between the dyed locks before shampooing, then after having undergone five shampooing operations according to the protocol described above. The lower the DE value, the more persistent the color with respect to shampoo washes.

[00259] The DE value is calculated according to the following equation:

[00261] In this equation, L*a*b* represent the values measured after dyeing the hair and after performing the shampoo washes, and L*oao*bo* represent the values measured after dyeing the hair but before shampoo washes. [00262] [Table 2]

[00263] The locks of hair dyed with composition A according to the invention, and washed with five shampoo washes, have low DE values.

[00264] Thus, the colored coating of the keratin fibers obtained with composition A according to the invention shows good persistence with respect to shampoo washes. Specifically, the locks of hair dyed with composition A according to the invention and washed with five shampoo washes show good persistence of the color.
