Abstract

The present invention relates to a process for treating keratin fibres with a composition comprising at least two different specific fatty acids and at least one modified polysaccharide.

Description

TECHNICAL FIELD

[0001] The present invention relates to a process for treating keratin fibres using a composition comprising at least two different specific fatty acids and at least one modified polysaccharide. BACKGROUND

[0002] Hair is damaged and weakened by external atmospheric agents such as pollution and bad weather and also by mechanical or chemical treatments such as brushing, combing, dyeing, bleaching, permanent waving, relaxing and repeated washing. As a result, the hair becomes damaged and, in the long term, can become dry, rough, brittle, dull, split and / or limp or sensitive to humidity, making it unmanageable, often frizzy and / or difficult to style in a humid environment, in particular in a very humid environment.

[0003] Thus, in order to overcome these drawbacks, it is usual practice to resort to hair treatments which use compositions intended to properly condition the hair by imparting satisfactory cosmetic properties to the hair, in particular a sense of suppleness (the hair is no longer rough), good disentangling properties (thus easy to comb) and good manageability of the hair (thus easy to style).

[0004] However, these hair treatments, generally based on silicone-based starting materials, can impart to the hair a greasy, heavy feel which is not always pleasant for the user. Furthermore, these hair treatments have little effect on controlling the volume of the keratin fibres and / or maintaining the hairstyle and / or the order of the hair in a humid or very humid environment.

[0005] In addition, the formulation of cosmetic products that are environmentally friendly, i.e. products whose design and development take into account environmental problems, is becoming an important issue in helping to meet global challenges. It therefore proves necessary to propose more sustainable compositions, thus making it possible in particular to respond to these environmental challenges by reducing the use of compounds of petroleum chemical origin.

[0006] Thus, there is a real need to develop a hair treatment process which can remedy these drawbacks and which makes it possible in particular to preserve or even improve the quality of the fibres, in particular the suppleness, the disentangling, the smoothness, the order and / or the shine, and to limit the formation of frizz and / or the increase in volume of the whole head of hair in a humid environment, in order to facilitate the styling of the hair in a humid environment. Ideally, such a process must not use any silicone starting materials.

[0007] The applicant has surprisingly discovered that all or some of these objectives can be achieved by the process according to the invention. SUMMARY

[0207] The pigments that can be used are especially chosen from organic and / or mineral pigments known in the art, especially those described in Kirk-Othmer’s Encyclopedia of Chemical Technology and Ullmann’s Encyclopedia of Industrial Chemistry.

[0208] They can be natural, of natural origin or non-natural.

[0210] The pigments can be chosen, for example, from mineral pigments, organic pigments, lakes, pigments with special effects such as nacres or glitter flakes, and mixtures thereof.

[0211] The pigments can be mineral pigments. The term “mineral pigments” means any pigment meeting the definition in the chapter on inorganic pigments in Ullmann’s encyclopaedia. Among the mineral pigments that can be used in the application, mention can be made of iron oxides, chromium oxides, manganese violet, ultramarine blue, chromium hydrate, ferric blue and titanium oxides.

[0212] The pigments can be organic pigments. The term "organic pigments" means any pigment satisfying the definition in the chapter on organic pigments in Ullmann's encyclopedia.

These composite pigments can in particular be composed of particles comprising an inorganic core, at least one binder for attaching an organic pigment to the core and at least one organic pigment at least partially covering the core.

[0226] The organic pigments can also be lakes. The term "lake" means a dye adsorbed onto an insoluble particle, the assembly thus obtained remaining insoluble during use.

[0227] The inorganic substrate onto which the dye is adsorbed is, for example, alumina, silica, calcium sodium borosilicate, or calcium aluminum borosilicate and aluminum.

[0228] Among these dyes, mention can be made of carminic acid. Mention can 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 (CI 61 570), D&C Yellow 10 (CI 77 002), D&C Green 3 (CI 42 053), D&C Blue 1 (CI 42090).

[0229] An example of a lake that can be mentioned is the product known under the name D&C Red 7 (CI 15 850:1).

[0230] The pigments can also be pigments with special effects. The term "pigments with special effects" means pigments that generally produce a colored appearance that is not uniform and that varies as a function of the conditions of observation (light, temperature, angle of observation, etc.) (characterized by a certain shade, a certain vivacity and a certain level of luminance). They are thus distinguished from colored pigments that provide a standard uniform opaque, semi-opaque or transparent shade.

[0231] There are several types of pigments with special effects: those with low refractive index, such as fluorescent or photochromic pigments, and those with higher refractive index, such as nacres, interference pigments or glitter flakes.

[0232] Examples of pigments with special effects that can be mentioned include nacreous pigments such as mica coated with titanium or coated with bismuth oxychloride; colored nacreous 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 with chromium oxides, mica coated with titanium and an organic pigment as defined previously, and also nacreous pigments based on bismuth oxychloride. Nacreous pigments that can be mentioned include the nacres Cellini (mica-Ti02-lake) sold by the company BASF, Prestige (mica-Ti02) sold by the company Eckart, Prestige Bronze (mica-Fe203) sold by the company Eckart and Colorona (mica-Ti02-Fe203) sold by the company Merck.

[0233] Mention can also be made of gold-colored nacres sold notably by the company BASF under the names Brilliant Gold 212G (Timica), Gold 222C (Cloisonne), Sparkle Gold (Timica), Gold 4504 (Chromalite) and Monarch Gold 233X (Cloisonne); bronze-colored nacres sold notably by the company Merck under the names Bronze Fine (17384) (Colorona) and Bronze (17353) (Colorona) and by the company BASF under the name Super Bronze (Cloisonne); orange-colored nacres sold notably by the company BASF under the names Orange 363C (Cloisonne) and Orange MCR 101 (Cosmica) and by the company Merck under the names Passion Orange (Colorona) and Matte Orange (17449) (Microna); brown-colored nacres sold notably by the company BASF under the names Nu-antique Copper 340XB (Cloisonne) and Brown CL4509 (Chromalite); nacres with a coppery tint sold notably by the company BASF under the name Copper 340A (Timica); nacres with a reddish tint sold notably by the company Merck under the name Sienna Fine (17386) (Colorona); nacres with a yellowish tint sold notably by the company BASF under the name Yellow (4502) (Chromalite); red nacres with a golden tint sold notably by the company BASF under the name Sunstone G012 (Gemtone); pink nacres sold notably by the company BASF under the name Tan Opale G005 (Gemtone); black nacres with a golden tint sold notably by the company BASF under the name Nu-antique Bronze 240 AB (Timica); blue nacres sold notably by the company Merck under the name Matte Blue (17433) (Microna); white nacres with a silvery tint sold notably by the company Merck under the name Xirona Silver; and golden green pink-orange nacres sold notably by the company Merck under the name Indian Summer (Xirona); and mixtures thereof.

[0234] As still examples of nacres, mention can also be made of particles comprising a borosilicate substrate coated with titanium oxide.

[0235] Particles comprising a glass substrate coated with titanium oxide are especially sold under the name Metashine MC1080RY by the company Toyal.

[0236] Finally, examples of nacres that can also be mentioned include polyethylene terephthalate glitter flakes, especially those sold under the name Silver Glitter Flakes 1 P 0.004 X 0.004 by the company Meadowbrook Inventions. Multilayer pigments based on synthetic substrates such as alumina, silica, calcium sodium borosilicate, calcium aluminum borosilicate and aluminum can also be envisaged.

[0237] Pigments with special effects can also be chosen from reflective particles, i.e. especially from particles whose size, structure, especially the thickness of the layer they are made of, and their physical and chemical properties and surface state allow them to reflect incident light. If appropriate, this reflection can be of sufficient intensity, when they are applied to the support to be made up, to produce, at the surface of the composition or mixture, points of highlights visible to the naked eye, i.e. points that appear sparkling, brighter in contrast with their environment.

[0238] Reflective particles can be chosen so as not to significantly alter the coloring effect produced by the coloring agents with which they are combined, and more particularly so as to optimize this effect in terms of color rendering. They can more particularly have a yellow, pink, red, bronze, orange, brown, gold and / or copper color or tint.

[0239] These particles can have different forms and especially can be in flaky or globular form, in particular in spherical form.

[0240] Regardless of their form, reflective particles can or can not have a multilayer structure, and in the case of a multilayer structure, can have, for example, at least one layer of uniform thickness, especially of reflective material.

[0241] When reflective particles do not have a multilayer structure, they can consist, for example, of metal oxides, especially titanium or iron oxides obtained synthetically.

[0242] When reflective particles have a multilayer structure, they can comprise, for example, a natural or synthetic substrate, especially a synthetic substrate at least partially coated with at least one layer of reflective material, especially at least one metal or metallic material. The substrate can be made of one or more organic and / or mineral materials.

[0243] More particularly, it can be chosen from glass, ceramic, graphite, metal oxides, aluminum oxide, silicon dioxide, silicates, especially aluminosilicates and borosilicates, and synthetic mica, and mixtures thereof, this list not being limiting.

[0244] The reflective material can comprise a metallic layer or a layer of a metallic material.

[0245] Reflective particles are notably described in JP-A-09188830, JP-A-10158450, JP-A-10158541, JP-A-07258460 and JP-A-05017710.

[0246] Furthermore, as an example of reflective particles comprising a mineral substrate coated with a metallic layer, mention can also be made of particles comprising a silver-coated borosilicate substrate.

[0247] Particles with a silver-coated glass substrate in the form of flakes are sold by the company Toyo under the name Microglass Metashine REFSX 2025 PS. Particles with a glass substrate coated with a nickel / chromium / molybdenum alloy are sold by the same company under the names Crystal Star GF 550 and GF 2525.

[0248] Particles comprising a metallic substrate, such as silver, aluminium, iron, chromium, nickel, molybdenum, gold, copper, zinc, tin, magnesium, steel, bronze or titanium, coated with at least one layer of at least one metal oxide, such as titanium oxide, aluminium oxide, iron oxide, cerium oxide, chromium oxide, silicon oxide, and mixtures thereof, can also be used.

[0249] Examples that can be mentioned include aluminium, bronze or copper powders coated with Si02, sold by the company Eckart under the name Visionaire.

[0250] Interference pigments not attached to a substrate, such as liquid crystals (Helicones HC from Wacker) or interference holographic flakes (Geometric Pigments or Spectraf / x from Spectratek) can also be mentioned. Special-effect pigments also include fluorescent pigments (whether these are substances that fluoresce under daylight or substances that produce ultraviolet fluorescence), phosphorescent pigments, photochromic pigments, thermochromic pigments and quantum dots (for example sold by the company Quantum Dots Corporation).

[0251] The various pigments that can be used in the present application make it possible to obtain a wide range of colours, and also specific optical effects, such as metallic effects or interference effects.

[0252] The size of the pigments used in the composition according to the application is generally between 10 nm and 200 pm, preferably between 20 nm and 80 pm and more preferentially between 30 nm and 50 pm.

[0253] The pigments can be dispersed in the composition by means of a dispersant.

[0254] The dispersants serve to protect the dispersed particles from their agglomeration or flocculation. The dispersants can be surfactants, oligomers, polymers or mixtures of several of these, carrying one or more functional groups having 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 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 and of C8 to C20 fatty acids, and esters of polyols such as glycerol or diglycerol, 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, are used in particular.

[0255] As other dispersants that can be used in the composition of the application, mention can be made of quaternary ammonium derivatives of polycondensed fatty acids, such as Solsperse 17 000 sold by the company Avecia, and polydimethylsiloxane / oxypropylene mixtures, such as those sold under the references DC2-5185 and DC2-5225 C by the company Dow Corning.

[0256] The pigments used in the composition can be surface-treated with organic agents.

[0257] Thus, the pigments that have been previously subjected to surface treatment usable in the context of the application are pigments that have been subjected, in whole or in part, to a surface treatment of chemical, electronic, electrochemical, mechanochemical or mechanical nature with organic agents, such as those described notably in Cosmetics and Toiletries, February 1990, Volume 105, pages 53-64, then dispersed in the composition according to the application. These organic agents can be chosen, for example, from waxes, such as 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; lecithin; sodium, potassium, magnesium, iron, titanium, zinc or aluminium salts of fatty acids, such as aluminium stearate or aluminium laurate; metal alkoxides; polyethylenes; (meth)acrylic polymers, such as polymethyl methacrylate; polymers and copolymers containing acrylate units; alkanolamines; silicone compounds, such as silicones, in particular polydimethylsiloxanes; organofluoro compounds, such as perfluoroalkyl ethers; fluorosilicone compounds.

[0258] The surface-treated pigments that can be used in the composition can also have been treated with a mixture of these compounds and / or can have undergone several surface treatments.

[0259] The surface-treated pigments that can be used in the context of the application can be prepared according to surface treatment techniques well known to the person skilled in the art or can be purchased as such.

[0260] Preferably, the surface-treated pigments are coated with an organic layer.

[0261] The organic agents that treat the pigments can be deposited on the pigments by evaporation of the solvent, by chemical reaction between the molecules of the surface agent or by formation of a covalent bond between the surface agent and the pigments.

[0262] The surface treatment can thus be carried out, for example, by chemical reaction of the surface agent with the surface of the pigments and by formation of a covalent bond between the surface agent and the pigments or fillers. This method is described notably in patent US 4 578 266.

[0263] Preferably, organic agents that covalently bond to the pigments are used.

[0264] The agents used for the surface treatment can represent from 0.1 % to 50% by weight relative to the total weight of the surface-treated pigments, preferably from 0.5% to 30% by weight relative to the total weight of the surface-treated pigments and even more preferentially from 1 % to 20% by weight.

[0265] Preferably, the surface treatment agent of the pigments is chosen from the following treatment agents:

[0266] - PEG-silicone treatment agents, such as AQ surface treatment agent sold by LCW;

[0267] - Dimethicone treatment agents, such as Covasil 3.05 surface treatment agent sold by LCW;

[0268] - Dimethicone / methyl trimethiconate treatment agents, such as Covasil 4.05 surface treatment agent sold by LCW;

[0275] - Dimethicone / methyl trimethiconate treatment agents, such as Covasil 4.05 surface treatment agent sold by LCW;

[0276] - Dimethicone / methyl trimethiconate treatment agents, such as Covasil 4.05 surface treatment agent sold by LCW;

[0280] - Dimethicone / methyl trimethiconate treatment agents, such as Covasil 4.05 surface treatment agent sold by LCW.

[0281] According to a particular embodiment of the application, the dispersant is present with the organic or mineral pigments in the form of microparticles of sub-micrometric size.

[0282] The term "sub-micrometric" or "sub-micron" means that the pigments have a particle size which has been micronized by a micronization process and have an average particle size of less than a micrometer (pm), in particular between 0.1 and 0.9 pm, and preferably between 0.2 and 0.6 pm.

[0332] Composition (C)

[0333] According to a second aspect, a subject of the application is a composition (C) as previously described.

[0334] Use

[0335] According to a third aspect, a subject of the application is the use of a composition (C) as previously described for caring for keratin fibres, preferably for imparting a sense of suppleness and / or smoothness and / or shine to keratin fibres, more preferentially for imparting a sense of suppleness and / or smoothness to them.

[0336] According to a fourth aspect, a subject of the application is the use of a composition (C) as previously described for protecting keratin fibres from moisture, preferably for limiting the formation of curls and / or the increase in volume of a whole head of hair in a humid environment. Examples

[0337] The following examples will allow the application to be more clearly understood, however they are not limiting in nature. In the following examples, all the amounts are expressed in percentage by mass relative to the total weight of the composition, unless otherwise indicated.

[0338] The following compositions C1 to C9 were prepared according to the preparation protocol described below:

[0339] [Table 1]

[0340]

[0341] [Table 2]

[0342]

[0343] Method for preparing compositions C1 to C9

[0344] The two acids were mixed in a flask. The mixture was heated at 70°C under stirring for 1 hour. After the temperature of the reaction medium had returned to room temperature, compound E was added to the resulting liquid and the mixture was heated again at 70°C under stirring for 20 minutes. After return to room temperature, compositions C1 to C9 were obtained in the form of colourless, transparent, slightly viscous, oily liquids.

[0345] Example 1: Evaluation of hair hold in a humid environment

[0346] The hold of the hair styles, i.e. the curl formation and volume increase of the whole head of hair in a humid environment, of compositions C1 to C4 was evaluated according to the evaluation protocol described hereafter.

[0347] Hair tresses used

[0348] A 27 cm long tress of Brazilian hair having type IV curls was used, 2.7 g.

[0349] Evaluation protocol

[0350] Before application of the test compositions, the tresses were washed with DOP shampoo (0.4 g / g of hair).

[0351] Then 81 mg of each test composition was applied to a separate wet tress, the wet tresses being previously wrung out and wiped dry on blotting paper. This application was carried out by hand, while massaging the hair fibres.

[0352] The hair tresses were then combed, detangled and placed in a glove box at 20% relative humidity at 25°C for 2 hours.

[0353] The tresses were then placed in an oven at 80% relative humidity, 25°C for 24 hours.

[0354] The volume and curliness measurements were carried out by measuring the width at the middle height of the tresses on leaving the oven and were compared with the values obtained for reference tresses not treated with a composition according to the application.

[0355] Evaluation results

[0356] The measurements of the width at the middle height of the tresses (in cm) are summarised in the following table:

[0357] [Table 3]

[0358]

[0359] It can be seen that the values of the width at the middle height of the tresses of the tresses treated via the process according to the application are lower than those of the reference tresses.

[0360] The method according to the application thus makes it possible to limit the formation of curls and the increase in the volume of the hair in a humid environment, even in the absence of silicone-based starting materials.

[0361] Example 2: Evaluation of "smooth feel" via strain determination method

[0362] The method comprises recording the friction of a dry or wet hair strand when it is displaced in the root / ends direction between two pads clamping it with constant compression. This method thus makes it possible to evaluate the "smoothness" by imitating the passage of two fingers along the strand.

[0363] The smaller the friction, the smoother the surface state of the hair.

[0364] The "smoothness" of compositions C1, C2, C7 and C8 was evaluated according to the evaluation protocol described below.

[0365] Hair strands used

[0366] For this study, bleached Caucasian hair strands (alkali solubility AS20) were used.

[0367] Evaluation protocol

[0368] The test compositions were applied according to the leave-on and rinse-off protocols described below, followed by wet and dry measurements.

[0369] The force ratio between the treated hair and the untreated hair was thus determined: F 经处理的 (W) / F 未经处理的 (W).

[0370] Leave-on protocol

[0371] 1 ) The strands were washed with DOP shampoo using a bath ratio of 0.4 g / g of hair;

[0372] 2) The composition was applied to the still wet hair at a bath ratio of 0.15 g / g of hair, without leave-on time.

[0373] Rinse-off protocol

[0374] 1 ) The strands were washed with DOP shampoo using a bath ratio of 0.4 g / g of hair;

[0375] 2) The composition was applied to the still wet hair at a bath ratio of 0.4 g / g of hair, followed by a leave-on time of 5 min.

[0376] 3) Rinse: 15 times under tap water, 2 times dried with the fingers, wetted with water and then finally dried with tweezers.

[0377] The measurements were carried out on still wet hair or on hair dried in an oven at 60°C for 15 min.

[0378] Results

[0379] The results are summarized in the following table:

[0380] [Table 4]

[0381]

[0382] Compared to untreated hair, lower friction on dry and wet hair was observed for hair treated via the method according to the application. The hair surface is smoother even in the absence of silicone-based starting materials. The treated hair is softer and easier to comb and detangle compared to untreated hair.
