Abstract

The present invention relates to a method for treating keratin fibers using 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 method for treating keratin fibers using a composition comprising at least two different specific fatty acids and at least one modified polysaccharide. [Background technology]

[0002] Hair is damaged and weakened by external atmospheric agents, such as pollution and bad weather, as well as by mechanical or chemical treatments, such as brushing, combing, hair dyeing, bleaching, permanent waves, relaxing, and repeated washing. Consequently, hair becomes damaged and, over time, dry, rough, brittle, dull, and split, and / or softened or humidity-sensitive, making it difficult to manage, often with frizz, and / or difficult to style in humid environments, especially very humid ones.

[0003] Therefore, in order to overcome these shortcomings, it is common to rely on hair treatments that utilize compositions intended to properly condition the hair by providing satisfactory cosmetic properties, particularly a soft feel (the hair is no longer coarse), good detangle properties that allow for easy combing, and good manageability that makes the hair easy to style.

[0004] However, hair treatments, which are often based on silicone-based starting materials, can give hair a greasy and heavy feel, which is not always pleasant for the user. Furthermore, these hair treatments have little to no effect on regulating the amount of keratin fibers and / or maintaining hairstyle and / or hair discipline in humid or very wet environments.

[0005] Furthermore, the formulation of environmentally friendly cosmetics—that is, products designed and developed with environmental issues in mind—is becoming a major concern for contributing to the solution of global challenges. Therefore, it has proven essential to propose more sustainable compositions, thereby enabling the meeting of these environmental challenges, particularly by reducing the use of petrochemical compounds. [Overview of the project] [Problems that the invention aims to solve]

[0006] Therefore, there is a real need to develop a hair treatment method that can improve upon its shortcomings and maintain or further improve the quality of the fibers, especially their softness, ease of detangling, smoothness, discipline, and / or shine, and that can continuously limit the formation of frizz and / or increase in hair volume in humid environments in order to facilitate hair styling in humid environments. Such a method should ideally not use silicone starting materials.

[0120] The usable pigments are selected from organic and / or inorganic pigments known in the art, particularly those described in Kirk-Othmer's Encyclopedia of Chemical Technology and Ullmann's Encyclopedia of Industrial Chemistry.

[0121] These may be natural products, of natural origin, or non-natural products.

[0122] The pigment may be in the form of a pigment powder or a paste. It may be coated or uncoated.

[0123] The pigments may be selected from, for example, inorganic pigments, organic pigments, lakes, pearlescent agents, or glitter flakes, as well as mixtures thereof, that have special effects.

[0124] The pigment may be an inorganic pigment. The term "inorganic pigment" refers to any pigment that meets the definition in the chapter on inorganic pigments in Ullmann's encyclopaedia. Among the inorganic pigments useful for the present invention are iron oxide, chromium oxide, manganese violet, ultramarine blue, chromium hydrate, ferric blue, and titanium dioxide.

[0125] The pigment may be an organic pigment. The term "organic pigment" refers to any pigment that meets the definition in the chapter on organic pigments in Ullmann's encyclopedia.

[0126] Organic pigments can be selected from, in particular, nitroso, nitro, azo, xanthene, pyrene, quinoline, anthraquinone, triphenylmethane, fluorane, phthalocyanine, metal complexes, isoindolinone, isoindoline, quinacridone, perinone, perylene, diketopyrrolopyrrole, indigo, thioindigo, dioxazine, triphenylmethane, and quinophthalone compounds.

The composite pigments may, in particular, consist of particles comprising an inorganic core material, at least one binder for bonding an organic pigment to the core material, and at least one organic pigment covering at least a portion of the core material.

[0130] Organic pigments can also be lakes. The term "lake" refers to a pigment adsorbed onto insoluble particles, and therefore the resulting composite remains insoluble even when in use.

[0131] Examples of inorganic substrates for adsorbing dyes include alumina, silica, sodium calcium borosilicate or aluminum calcium borosilicate, and aluminum.

[0132] Among dyes, carminic acid is one example. Other dyes known by the following names can also be mentioned: 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), and D&C Blue 1 (CI 42 090).

[0133] An example of a rake is the product known as D&C Red 7 (CI 15 850:1).

[0134] The pigments may also be pigments with special effects. The term "pigments with special effects" generally refers to pigments that produce a non-uniform and variable colored appearance (characterized by a specific hue, a specific brilliance, and a specific level of brightness) depending on the observation conditions (light, temperature, observation angle, etc.). Thus, they differ from colored pigments that exhibit a standard, uniform opaque, translucent, or transparent hue.

[0135] There are several types of pigments that have special effects: those with a low refractive index, such as fluorescent or photochromic pigments, and those with a high refractive index, such as pearlescent agents, interference pigments, or luminous flakes.

[0136] Examples of pigments with special effects that can be mentioned include pearlescent pigments such as mica coated with titanium or bismuth oxychloride, colored pearlescent pigments such as mica coated with titanium and iron oxide, mica coated with iron oxide, mica coated with titanium, and especially mica coated with ferric blue or chromium oxide, mica coated with titanium and coated with the organic pigments defined above, and pearlescent pigments based on bismuth oxychloride. Examples of pearlescent pigments include pearlisers such as Cellini (mica-TiO2-lake) sold by BASF, Prestige (mica-TiO2) sold by Eckart, Prestige Bronze (mica-Fe2O3) sold by Eckart, and Colorona (mica-TiO2-Fe2O3) sold by Merck.

[0137] Gold pearlescent polishes, especially those sold by BASF under the names Brilliant Gold 212G (Timica), Gold 222C (Cloisonne), Sparkle Gold (Timica), Gold 4504 (Chromalite), and Monarch Gold 233X (Cloisonne); bronze pearlescent polishes, especially those sold by Merck under the names Bronze Fine (17384) (Colorona) and Bronze (17353) (Colorona), and by BASF under the name Super Bronze (Cloisonne); orange pearlescent polishes, especially those sold by BASF under the names Orange 363C (Cloisonne) and Orange MCR 101 (Cosmica), and by Merck under the names Passion Orange (Colorona) and Matte Products sold under the name Orange (17449) (Microna); brown pearlescent polishes, especially those sold by BASF under the names Nu-antique Copper 340XB (Cloisonne) and Brown CL4509 (Chromalite); copper-colored pearlescent polishes, especially those sold by BASF under the name Copper 340A (Timica); reddish pearlescent polishes, especially those sold by Merck under the name Sienna Fine (17386) (Colorona); yellowish pearlescent polishes, especially those sold by BASF under the name Yellow (4502) (Chromalite); golden-colored red pearlescent polishes, especially those sold by BASF under the name Sunstone G012 (Gemtone); pink pearlescent polishes, especially those sold by BASF under the name Tan Opale Products sold under the name G005 (Gemtone); golden-tinged black pearlescent polishes, especially those sold by BASF under the name Nu-Antique Bronze 240 AB (Timica); blue pearlescent polishes, especially those sold by Merck under the name Matte Blue (17433) (Microna); silvery-tinged white pearlescent polishes, especially those sold by Merck under the name Xirona Silver;Also mentioned are gold, green, pink, and orange pearlescent lusters, particularly those sold by Merck under the name Indian Summer (Xirona); and mixtures thereof.

[0138] Further examples of pearlescent agents include particles containing a borosilicate substrate coated with titanium dioxide.

[0139] Particles containing a glass substrate coated with titanium dioxide are sold by Toyal under the name Metashine MC1080RY.

[0140] Finally, as an example of a pearlescent luster, polyethylene terephthalate glitter flakes, particularly those sold by Meadowbrook Inventions under the name Silver 1P 0.004X0.004 (silver glitter flakes), can also be mentioned. Synthetic substrates, such as multilayer pigments based on alumina, silica, calcium sodium borosilicate, calcium aluminum borosilicate, and aluminum, can also be considered.

[0141] Pigments with special effects can also be selected from reflective particles, i.e., particles capable of reflecting incident light due to their size, structure, especially the thickness of the layers comprising them, as well as their physical and chemical properties and surface condition. This reflection can, where appropriate, be strong enough to produce visible bright spots on the surface of the composition or mixture when applied to a support to be made up, i.e., brighter spots that stand out more than their surroundings.

[0142] Reflective particles may be selected to optimize this effect, more specifically in terms of color rendering, so as not to significantly alter the color effect produced by the colorants they are combined with. More specifically, these may have colors or hues of yellow, pink, red, bronze, orange, brown, gold, and / or copper.

[0143] These particles can have various forms, particularly plate-like or spherical forms, and especially spherical forms.

[0144] Reflective particles, regardless of their form, may or may not have a multilayer structure, and in the case of a multilayer structure, they may have, for example, at least one layer of a reflective material having a uniform thickness.

[0145] If the reflective particles do not have a multilayer structure, they may be composed of metal oxides, particularly titanium oxide or iron oxide obtained by synthesis.

[0146] If the reflective particles have a multilayer structure, they may include, for example, a natural or synthetic substrate, particularly a synthetic substrate, at least partially coated with a reflective material, especially at least one layer of at least one metal or metallic material. The substrate can be made from one or more organic and / or mineral materials.

[0147] More specifically, this can be selected from, but is not limited to, glass, ceramics, graphite, metal oxides, alumina, silica, silicates, especially aluminosilicates and borosilicates and synthetic mica and mixtures thereof.

[0148] The reflective material may include a layer of metal or metallic material.

[0149] Reflective particles are described in particular in Japanese Patent Publication No. 09-188830A, Japanese Patent Publication No. 10-158450A, Japanese Patent Publication No. 10-158541A, Japanese Patent Publication No. 07-258460A, and Japanese Patent Publication No. 05-017710A.

[0150] Further examples of reflective particles containing inorganic substrates coated with a metal layer include particles containing a silver-coated borosilicate substrate.

[0151] Small plate-shaped silver-coated glass substrate particles are sold by Toyal under the name Microglass Metashine REFSX 2025 PS. Glass substrate particles coated with nickel / chromium / molybdenum alloy are sold by the same company under the names Crystal Star GF 550 and GF 2525.

[0152] Particles containing a metal substrate such as silver, aluminum, iron, chromium, nickel, molybdenum, gold, copper, zinc, tin, magnesium, steel, bronze, or titanium may also be used, and the substrate is 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 oxide, and mixtures thereof.

[0153] Examples include SiO2-coated aluminum powder, bronze powder, or copper powder, which are sold by Eckart under the name Visionaire.

[0154] Other examples include interference pigments that are not bonded to a substrate, such as liquid crystals (Helicones HC from Wacker) or interference holographic flakes (Geometric Pigments or Spectra f / x from Spectratek). Special effect pigments also include fluorescent pigments (these are either substances that fluoresce in daylight or substances that produce ultraviolet fluorescence), phosphorescent pigments, photochromic pigments, thermochromic pigments, and quantum dots, such as those sold by Quantum Dots Corporation.

[0155] The diversity of pigments that can be used in this invention makes it possible to obtain a wide range of colors, and it is also possible to obtain specific optical effects such as metallic effects or interference effects.

[0156] The size of the pigments used in the compositions according to the present invention is generally 10 nm to 200 μm, preferably 20 nm to 80 μm, and more preferably 30 nm to 50 μm.

[0157] The pigment may be dispersed in the composition using a dispersant.

[0158] The dispersant plays a role in preventing aggregation or floc formation of dispersed particles. This dispersant may be a surfactant, oligomer, polymer, or a mixture thereof having one or more functional groups that have a strong affinity for the surface of the particles to be dispersed. In particular, these may be physically or chemically bonded to the pigment surface. This dispersant also includes at least one functional group that is miscible with or soluble in the continuous medium. In particular, esters of 12-hydroxystearic acid, especially C8-C20 fatty acids and polyols such as glycerol or diglycerol, for example, poly(12-hydroxystearic acid) stearate with a molecular weight of approximately 750 g / mol, for example, the product sold by Avecia under the name Solsperse 21000, polyglyceryl-2 dipolyhydroxystearate (CTFA name) sold by Henkel under the trade code Dehymyls PGPH, or other polyhydroxystearic acid, for example, the product sold by Uniqema under the trade code Arlacel P100, and mixtures thereof are used.

[0159] Other dispersants that may be used in the compositions of the present invention include quaternary ammonium derivatives of polycondensed fatty acids, such as Solsperse 17000 sold by Avecia, and polydimethylsiloxane / oxypropylene mixtures, such as those sold by Dow Corning under reference numbers DC2-5185 and DC2-5225 C.

[0160] The pigments used in the composition may be surface-treated with organic agents.

[0161] Therefore, pre-surface-treated pigments useful in connection with the present invention are pigments that have been subjected to a surface treatment with chemical, electronic, electrochemical, mechanochemical, or mechanical properties using an organic agent, either entirely or partially, such as those described in particular in Cosmetics and Toiletries, February 1990, Vol. 105, pp. 53-64, and are then dispersed in the composition of the present invention. The organic agent can be selected from, for example, waxes, such as 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, lecithin, sodium, potassium, magnesium, iron, titanium, zinc, or aluminum salts of fatty acids, such as stearic acid or aluminum laurate, metal alkoxides, polyethylene, (meth)acrylic polymers, such as polymethyl methacrylate, polymers and copolymers containing acrylate units, alkanolamines, silicone compounds, such as silicones, particularly polydimethylsiloxane, organofluorine compounds, such as perfluoroalkyl ethers and fluorosilicone compounds.

[0162] Surface-treated pigments useful in this composition may be treated with a mixture of the compound and / or subjected to several surface treatments.

[0163] Surface-treated pigments useful in connection with the present invention may be prepared according to surface treatment techniques well known to those skilled in the art, or they may be commercially available as is.

[0164] Preferably, the surface-treated pigment is coated with an organic layer.

[0165] Organic agents for treating pigments can be deposited on the pigment by evaporating the solvent, causing a chemical reaction between the molecules of the surface treatment agent, or by forming covalent bonds between the surface treatment agent and the pigment.

[0166] Therefore, surface treatment can be carried out, for example, by chemically reacting a surface treatment agent with the pigment surface to create a covalent bond between the surface treatment agent and the pigment or filler. This method is described in particular in U.S. Patent No. 4,578,266.

[0167] Organic agents that form covalent bonds with the pigment are preferably used.

[0168] The agent used for surface treatment may constitute 0.1% to 50% by mass, preferably 0.5% to 30% by mass, and more preferably 1% to 20% by mass, relative to the total mass of the pigment to be surface treated.

[0169] Preferably, the surface treatment agent for the pigment is one of the following: -PEG-silicone treatment agents, e.g., AQ surface treatment agents sold by LCW; - Methicone treatment agents, for example, SI surface treatment agents sold by LCW; - Dimethicone treatment agents, for example, Covasil 3.05 surface treatment agent sold by LCW, - Dimethicone / trimethylsiloxysilicate treatment agents, for example, Covasil 4.05 surface treatment agent sold by LCW, - Magnesium myristate treatment agents, for example, MM surface treatment agents sold by LCW, - Aluminum dimyristate treatment agents, for example, MI surface treatment agents sold by Miyoshi, - Perfluoropolymethylisopropyl ether treatment agents, for example, FHC surface treatment agents sold by LCW, - Isostearyl sebacate treatment agents, e.g., HS surface treatment agents sold by Miyoshi; - Perfluoroalkyl phosphate treatment agents, such as PF surface treatment agents sold by Daito; -Acrylate / dimethicone copolymers and perfluoroalkyl phosphate treatment agents, such as FSA surface treatment agents sold by Daito; - Polymethylhydrogenosiloxane / perfluoroalkyl phosphate treatment agents, such as FS01 surface treatment agent sold by Daito; - Acrylates copolymer / dimethicone treatment agents, such as the ASC surface treatment agent sold by Daito; - Isopropyl titanium triisostearate treatment agents, e.g., ITT surface treatment agents sold by Daito; - Acrylates copolymer treatment agents, such as the APD surface treatment agent sold by Daito; - Perfluoroalkyl phosphate / isopropyl titanium triisostearate treatment agents, e.g., PF+ITT surface treatment agents sold by Daito.

[0217] The following examples will allow for a clearer understanding of the present invention, but they do not limit the nature of the invention. In the following examples, unless otherwise specified, all quantities are expressed as mass percentages of the total mass of the composition.

[0218] Compositions C1 to C9 were prepared according to the preparation protocol described below.

[0219] [Table 15]

[0220]

Table 16

[0221] Method for preparing Compositions C1 to C9 Mix two acids in a flask. Heat the mixture with stirring at 70 °C for 1 hour. After the temperature of the reaction medium returns to room temperature, add Compound E to the resulting liquid and heat the mixture again with stirring at 70 °C for 20 minutes. After returning to room temperature, Compositions C1 to C9 are obtained in the form of a colorless, transparent, slightly viscous oily liquid.

[0222] Example 1: Evaluation of hairstyle hold in a humid environment Hairstyle hold, i.e., the formation of curls and the increase in hair volume in a humid environment, was evaluated for Compositions C1 to C4 according to the evaluation protocol described below.

[0223] Hair bundle used A 2.7 g hair bundle of Brazilian human hair with Type IV curls 27 cm long was used.

[0224] Evaluation protocol The hair bundle was washed with DOP shampoo (0.4 g per 1 g of hair) and then the test composition was applied.

[0225] Next, 81 mg of each test composition was applied to separate wet hair bundles, which were pre-wrung and gently patted on absorbent paper. This application was done with the fingers while massaging the hair fibers.

[0226] Next, the hair bundle was combed, the tangles were loosened, and it was placed in a glove box at 20% relative humidity and 25 °C for 2 hours.

[0227] Next, the hair bundle was placed in an oven at 80% relative humidity and 25 °C for 24 hours.

[0228] Volume and curl were measured by measuring the width of the hair bundle at an intermediate height after it came out of the oven, and compared with the values ​​obtained for a reference hair bundle that had not been treated with the composition according to the present invention.

[0229] Evaluation results The measurement results for the width (cm) of hair bundles at an intermediate height are summarized in the table below.

[0230] [Table 17]

[0231] It can be seen that the width value of the hair bundle at the intermediate height is lower for the hair bundle processed by the method according to the present invention than for the reference hair bundle.

[0232] Therefore, the method according to the present invention makes it possible to limit the formation of frizz and the increase in hair volume in a humid environment, even when silicone-based starting materials are not present.

[0233] Example 2: Evaluation of "smooth feel" using elongation measurement method This method involves recording the frictional force of a dry or wet hair bundle during root / end displacement between two pads that clamp it with constant compression. Thus, this method allows for the evaluation of a "smooth feel" by mimicking the passage of two fingers along a hair bundle.

[0234] The lower the friction, the smoother the surface of the hair becomes.

[0235] The "smooth feel" of compositions C1, C2, C7, and C8 was evaluated according to the evaluation protocol described below.

[0236] Hair bundles used For the study, bleached Caucasian human hair strands (alkaline solubility AS20) were used.

[0237] Evaluation protocol The test compositions were applied according to the leave-on and rinse-off protocols described below, followed by wet and dry measurements.

[0238] In this way, the force ratio between treated hair and untreated hair: F 処理 (W) / F 未処理 (W) was decided.

[0239] Leave-on protocol 1) Wash the hair strands with DOP shampoo using a bathing ratio of 0.4g per gram of hair; 2) Apply the composition to the hair while it is still wet, without any leave-on time, at a bathing ratio of 0.15 g / g of hair.

[0240] Rinse-off protocol 1) Wash the hair strands with DOP shampoo using a bathing ratio of 0.4g per gram of hair; 2) The composition was applied to the hair while it was still wet, at a bathing ratio of 0.4 g / g of hair, followed by a 5-minute leave-on period. 3) Rinsing: Rinse 15 times under running water, dry twice with fingers, moisten with water, and then dry completely with forceps.

[0241] Measurements were taken using either wet hair or hair dried in a 60°C oven for 15 minutes.

[0242] result The measurement results are summarized in the table below.

[0243] [Table 18]

[0244] Compared to untreated hair, lower friction is observed on both dry and wet hair treated by the method according to the present invention. The hair surface is smoother even without silicone-based starting materials. Treated hair is softer and easier to comb and detangle compared to untreated hair.
