Description

Technical Field

[0001] The present invention relates to a cosmetic composition comprising at least one natural resin, at least one volatile oil and at least one volatile alcohol in specific weight ratios. The present invention also relates to a cosmetic method which implements the application of such a cosmetic composition to keratin materials, in particular human keratin materials such as skin, hair or eyelashes. Background Art

[0002] Cosmetic products often require the use of film-forming polymers in order to obtain a product deposit with good cosmetic properties on keratin materials. The film-forming deposit needs to have good persistence for the deposit needs not to transfer during contact with fingers or clothing and also needs to have good resistance in contact with water (especially rain) or during showering, and the deposit needs to be insensitive to sweat or sebum and food fats (especially dietary fats such as oils).

[0003] Dispersions of polymer particles (usually acrylic acid) in an organic medium (such as hydrocarbon-based oils) are often used as film formers in cosmetic products such as mascara, eyeliner, eye shadow or lipstick. In order to improve the durability of cosmetics, silicone-based resins are also used. These dispersions are not always satisfactory in terms of tolerance to fatty substances, in particular dietary fat or sebum, which may limit their use in lip makeup, for example.

[0004] Furthermore, the field of cosmetic formulations is undergoing rapid changes. Consumers expect to use more natural products and need peace of mind regarding the ingredients in cosmetic formulations, in particular regarding their harmlessness, their low environmental footprint, their origin, or their renewable nature. In recent years, replacing synthetic polymers, and in particular silicones, in cosmetic formulations has become a major challenge.

[0005] Although some natural resins such as rosin (rosin resin) have been explored as tackifying resins, this must be combined with a high proportion of silicone resin, for example in order to increase the gloss and good durability of lip makeup (FR 2918272). However, document WO 2013 / 147113 discusses several problems encountered with such ingredients, such as: as the amount of silicone resin increases, a decrease in the flexibility of the cosmetic film is often observed; as the amount of rosin increases, a sticky effect of the cosmetic film occurs. This can produce a "heavy", thick or caked cosmetic feel.

[0006] Consumers are accustomed to certain sensory properties and textures, such as those characteristic of silicones and synthetic polymer fillers. Cosmetic chemists therefore have to deal with a double challenge: naturalness on the one hand, where silicone resins and synthetic polymers are increasingly being replaced by more natural starting materials or starting materials of more natural origin, and performance and sensory properties on the other hand, so that more natural formulations have efficacy and sensory properties that are at least comparable to those of the less natural formulations they are designed to replace.

[0007] Finally, it remains a technical challenge to successfully formulate natural resins that are solid at ambient temperature (25° C.) in cosmetics with a fluid liquid texture. Generally, natural resins are said to be soluble in chlorinated solvents, or benzene compounds, or large amounts of alcohol. Such solvents cannot be considered for cosmetic uses for the care or make-up of the skin, especially the lips, where even ethanol above a certain content may cause discomfort, dryness, irritation or even a burning sensation of the skin. Therefore, the present invention also aims to enable and simply prepare a cosmetic composition that provides improved persistence, based on ingredients that are as natural as possible and in a cosmetically acceptable medium.

[0008] In particular, the object of the present invention is to provide a cosmetic composition whose residual film after application adheres well to keratin materials, is elastic and shows the least possible chipping and the least possible detachment from the substrate, which is not sticky, has good durability with respect to external aggressors such as friction, is resistant to sweat and sebum, and is relatively insensitive to oils such as dietary oils.

[0009] Surprisingly, the inventors have shown that a specific combination of volatile alcohols and volatile oils not only makes it possible to effectively dissolve natural resins (including semi-solid and solid natural resins) at ambient temperature (25° C.), but also makes it possible to obtain a cosmetic composition the application of which gives rise to a film that proves to be both particularly resistant to friction and non-tacky.

[0029] The compositions according to the invention contain a physiologically acceptable medium.

[0030] In the present invention, the term "physiologically acceptable medium" means a non-toxic medium compatible with keratin materials, in particular with human skin (including the inside of the eyelids), mucous membranes, hair or lips. Cosmetic compositions are products that have a pleasant appearance, taste and feel and are intended for topical application.

[0031] The term "anhydrous composition" means a composition that contains less than 5% by weight of water relative to the total weight of the composition, preferably less than 1% by weight of water relative to the total weight of the composition, even more preferably less than 0.5% by weight of water, and in particular, is free of water.

[0038] Composition (A) - Oily Phase

[0039] According to a first aspect, a subject of the present invention is a composition as previously defined.

[0040] The Applicant has surprisingly observed that a composition A according to the invention comprising a natural resin, in particular a dissolved natural resin, in a specific mixture of a volatile oil and a volatile alcohol as defined below, makes it possible to obtain films having improved durability and being resistant to friction and non-tacky.

[0041] Natural resin

[0042] Resins are generally defined as solid, highly viscous or liquid substances of vegetable or synthetic origin. Resins have a number of characteristics specific to them, such as:

[0043] - the ability to harden permanently, for example for synthetic resins under the influence of temperature and for natural resins under the influence of oxygen;

[0044] - They are insoluble in water and most importantly their good adhesive and bonding properties.

[0045] Standard ISO 4618:2014 (fr) defines resin as "a generally amorphous macromolecular product with a consistency ranging from solid to liquid".

[0046] Natural resins are of virtually only plant origin (fossilized or harvested) and are secreted by plants and then exuded for defense, protection, and communication purposes in their ecosystems. Shellac is an exception, being of animal origin and secreted by the insect Coccus lacca.

[0047] For the purposes of the present invention, "natural resin", and in particular "plant resin", means any substance containing a minimum content of terpene compounds, i.e. at least 30% by weight of terpene compounds relative to the total weight of the substance (or material) in question, as chemically defined below, which substances are derived directly or indirectly from the secretions and exudates mainly of plants (and less frequently of animals) that serve as substances for the role of defence, protection and communication in their ecosystems.

[0048] Advantageously, the natural resins according to the invention are insoluble in water at ambient temperature (eg, unlike latex or gum).

[0049] Natural resins are also considered natural adhesives, which have the inherent ability to polymerize consistently and predictably without synthetic chemistry.

[0050] Preferably, the natural resin used in the composition according to the invention has a number average molecular weight less than or equal to 10 000 g / mol. The resin preferably has a number average molecular weight less than or equal to 10 000 g / mol, in particular in the range of 250 to 10 000 g / mol, preferably less than or equal to 5000 g / mol, in particular in the range of 250 to 5000 g / mol, better still less than or equal to 2000 g / mol, in particular in the range of 250 to 2000 g / mol, and even better still less than or equal to 1000 g / mol, in particular in the range of 250 to 1000 g / mol. The number average molecular weight (Mn) is determined by gel permeation liquid chromatography (THF solvent, calibration curve established using linear polystyrene standards, refractometer).

[0051] Thermal properties

[0052] - Softening point is the temperature at which a product reaches a certain softening degree under standardized conditions. The softening point indicates the temperature at which the product changes from a quasi-solid state to a plastic state during heating. The softening point can be measured for resins by the ring and ball method (or RBT, ring and ball temperature) according to standard ASTM E284;

[0053] -The melting point (or melting temperature) of a substance at a given pressure corresponds to the temperature at which the liquid and solid states of the substance can coexist in equilibrium;

[0054] - The glass transition temperature (Tg) of a material represents the temperature range through which the material passes from a rubbery state to a glassy, ​​solid (rigid) state.

[0055] The thermal properties of the resin, in particular Mp and Tg, can be measured by DSC (Differential Scanning Calorimetry), for example by a DSC 8000 apparatus from Perkin Elmer according to the following protocol:

[0056] - Protocol 1: Determination of melting temperature Mp and crystallization temperature Tc: Starting material alone or dissolved / dispersed in solvent, stainless steel plate, scan from 5°C to 90°C, scan rate 5°C.min-1.

[0057] - Protocol 2: Determination of glass transition temperature Tg: Measurement on second heating. Using an aluminum pan (40 μl) containing the starting material, a temperature scan (with isotherms) between -100°C and 150°C was performed to observe the glass transition temperature. For the glass transition temperature, the temperature ramp applied was 10°C / min (2 cycles).

[0058] Preferably, the glass transition temperature of the resin of the present invention is preferably in the range of 0°C to 200°C, more preferably 10°C to 100°C, even more preferably 20°C to 90°C, and even more preferably 30°C to 70°C.

[0059] Advantageously, the resins according to the invention are characterized in that they have a softening point, which represents the temperature at which they pass from the quasi-solid state to the plastic state during heating.

[0060] Preferably, the softening point of the resin of the present invention is preferably in the range of 20°C to 150°C, more preferably 30°C to 100°C, even more preferably 40°C to 90°C.

[0061] Depending on their category, some of the resins according to the invention may also have a melting temperature preferably below 360°C, preferably below 190°C and even more preferably below 90°C.

[0062] According to a preferred form of the invention, the resin does not have a melting temperature.

[0063] Botanical definition of resin:

[0064] Natural resins of plant or animal origin are generally defined by Ullmann's Encyclopedia of Industrial Chemistry, “Resins, Synthetic” 2012 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim, DOI: 10.1002 / 14356007.a23_089.pub2.

[0065] Natural resin can be Its botanical aspects Resins can be derived from gymnosperms (uncovered seeds) and angiosperms (covered seeds); angiosperms are subdivided into monocots (with one embryonic leaf) and dicots (with two embryonic leaves). They can also be selected based on their physical and chemical properties.

[0066] Natural resins include, inter alia, rosins (tall oil rosins, woods or gums derived from tree and plant exudates; wood extracts; or by-products from papermaking), fossil resins such as amber; extracted resins such as asphaltic rock; shellacs, such as those produced from insect secretions; and major derivatives thereof.

[0067] The resins of the invention are preferably of vegetable origin, in particular from plants or trees.

[0068] Fossil resins are (hard and semi-hard) resins collected from underground, where ancient forests that once disappeared for a long time were. Some of them are indeed no longer known. Due to aging or aging, some fossil resins have undergone considerable changes in their chemical structure, which may have taken thousands of years. The transition from fossil resins to modern resins may change. For example, they can include resins not only found in fossil form but also harvested from living plants. Semi-fossil varieties are collected from the foot of the tree that produces them (Ullmann's Encyclopedia of Industrial Chemistry [Ullmann's Encyclopedia of Industrial Chemistry], "Resins, Natural [natural resins] "2012 Willy-VCH Publishing Company (Wiley-VCHVerlag GmbH & Co.KGaA), Weinheim [Weinheim], DOI: 10.1002 / 14356007.a23_073) (Techniques de l'Ingénieur [Engineering Technology], "Résines Naturelles" [natural resins], 1982Bernard Delmond).

[0069] Harvested resin is recent (tender). Harvested resin is harvested from all living plants. Based on the composition of harvested resin, it is subdivided into:

[0070] -Oleoresins: natural solutions of resins in essential oils;

[0071] - Balsam: a resin characterized by a high proportion of benzoic and cinnamic acids and their esters;

[0072] - Gums: Resins consisting essentially of polysaccharides;

[0073] - Gums-resins: mixtures of resins and hydrophilic gums;

[0074] - Latex: milky composition of an organic substance dispersed in an aqueous medium: (Techniques de l'Ingénieur [Engineering techniques], "Résines Naturelles" [Natural resins], 1982 Bernard Delmond).

[0075] Among the resins of the present invention, particularly modern resins, those soluble in oil and / or alcohol are preferably in a water-soluble form such as a latex or gum.

[0076] According to a preferred mode of the invention, the resins of the invention are harvested resins; these are particularly advantageous from an ecological point of view since they are self-regenerating.

[0077] Preferably, the resins of the invention are modern. Advantageously, the resins used according to the invention rely on resources that do not compete with resins intended for food applications. Advantageously, the resins used in the compositions of the invention are derived from the recycling of by-products of the paper industry.

[0078] Chemical definition of resin

[0079] Chemically, natural resins are complex mixtures of several classes of compounds, whose presence and content define the class of resin (oleoresin, balsam, gum, etc.): essential oils, neutral and acidic components, and polysaccharides (exclusively found in gums).

[0080] The components that characterize the resins are the terpene compounds they contain, preferably in a content of at least 30% by weight relative to the weight of the resin.

[0081] "Terpenic compounds" means terpenes, hydrocarbons formed from isoprene with the general formula (C5H8)n and its many derivatives (alcohols, aldehydes, ketones, acids, etc.) containing the terpene structure (Website of the Académie de Montpellier [Montpellier Academy] on "lesterpènes" [terpenes]).

[0082] Among the terpene hydrocarbons, a distinction is made between monoterpenes of the empirical formula C10H16 (n=2), sesquiterpenes of the empirical formula C15H24 (n=3), diterpenes (C20H32) (n=4), disesquiterpenes (C25H40) (n=5), triterpenes (C30H48) (n=6), tetraterpenes (C40H64) (n=8) and other polyterpenes. Some have an acyclic structure; they include a plurality of double bonds, which corresponds to their empirical formula: 3 for C10H16, 5 for C20H32, 7 for C30H48. The rest have one or more rings, so that the number of double bonds is reduced, for example one ring and 2 double bonds for C10H16, or 2 rings and one double bond.

[0083] Advantageously, the resin of the invention contains at least 30% by weight of terpene compounds, preferably at least 40% by weight of terpene compounds, preferably at least 50% of terpene compounds and even more preferably at least 60% by weight of terpene compounds relative to the total weight of the resin or resinous substance used as starting material in the composition according to the invention.

[0084] Monoterpenes and sesquiterpenes are the main volatile compounds constituting, for example, essential oils. Polyterpenes derived from terpenes where n is greater than or equal to 4 (such as derivatives of diterpenes and triterpenes) are resinous compounds with a rather solid nature.

[0085] According to a preferred embodiment of the invention, the resin comprises at least 10% by weight, preferably at least 20% by weight, preferably at least 30% by weight, preferably at least 35% by weight of polyterpenoids, i.e. compounds derived from terpenes in which n is greater than or equal to 4, relative to the total weight of the resin representing 100%. Thus, resins having a fraction that is solid at ambient temperature (25° C.) are preferred. Advantageously, the resin used according to the invention is not volatile.

[0086] Advantageously, the polyterpene compounds of the resin or resinous substance used in the composition of the invention are mainly (more than 50% by weight relative to the total weight of polyterpenes) derived from diterpenes and / or triterpenes.

[0087] According to a preferred embodiment of the invention, the resin comprises less than 70% by weight of monoterpene or sesquiterpene compounds, i.e. compounds derived from terpenes in which n is less than 4, relative to the total weight of the resin representing 100%; preferably, the resin comprises less than 60% by weight, preferably less than 50% by weight, preferably less than 30% by weight, preferably less than 15% by weight of monoterpene or sesquiterpene compounds derived from terpenes in which n is less than 4, relative to the total weight of the resin representing 100%. Therefore, for the composition of the invention, it is preferred to limit the use of the most volatile resins, since they are less effective in terms of the durability of the cosmetic film.

[0088] A non-exhaustive list of terpene compounds that may be included in the natural resins of the present invention has been generated. This list lists families of terpene compounds that are subdivided based on the characteristic groups (alcohol function, ketone function, acid function, etc.) of each compound (as listed below).

[0110] a) Gramineae resin

[0111] Grass resin is a modern resin isolated from the species of Xanthorrhoea produced in Australia. Appearance. Known grass resins are yellow or red, and also differ from each other in their physical properties. Red grass resin is the most important. Acid value 60-110 (red), 125-140 (yellow); saponification value 160-200 (red), 200-240 (yellow). Unlike the red resin type, the yellow type contains benzoic acid cinnamic acid, p-coumaric acid ester and yellow resin tannin (about 80%). The red type contains erythritol tannin (about 85%).

[0112] According to one embodiment, the natural resin is selected from: a) grass resin a).

[0113] b) Amber

[0114] Amber is a fossilized resin from a coniferous tree (Pinites succinifera) of the Tertiary period. Amber was probably formed by a continuous stream of resin, which was shaped into its current form due to pressure, temperature and other influences over the course of thousands of years. Amber is mainly found in Sambia (Baltic coast) and the Kaliningrad Peninsula (Parmanikon region). They are obtained by collecting or fishing on the coast (sea amber), or by separation from the "blue earth" extracted in Parmanikon. Amber ranges from bright yellow to slightly brown (similar to the color of amber). The resin has an angular or rounded shape and different sizes, and may contain inclusions. Amber is a very hard resin that is almost insoluble in all solvents and is a very good dielectric. Amber acquires a negative charge by mechanical friction, and is therefore called "electronin" in ancient Greek. Amber decomposes at about 370°C without melting. Unlike other resins, amber contains organically bound sulfur. The composition of amber can vary greatly. The approximate elemental composition can be found in the literature: 78% carbon, 9.9% hydrogen, 11.7% oxygen, 0.4% sulfur and 0.2% ash; acid number 15-35, saponification number 90-125.

[0115] According to a specific embodiment of the present invention, the resin is selected from b) amber.

[0116] c) Asphalt rock and black asphalt

[0117] Asphaltenes are fossil resins also known by the name glossy pitch (see Asphalteet Bitume [Bitumen and Asphalt], Chapter 2). Asphaltenes are neutral resins based on thermoplastic hydrocarbons. According to DIN 55 946, asphaltenes are defined as natural bitumens with a low mineral content and a high level of hardness. This natural product appears to be formed from crude oil by evaporation of volatile components and by natural auto-oxidation and polymerization reactions. Hard natural bitumens (asphaltites) are found in Utah / Colorado (black asphalt), Virginia and Syria. The Utah asphalt deposits were discovered in 1860 by SH Gilson. Asphalt is extracted from Trinidad (Trinidad asphalt), Bermuda, Cuba, Mexico and Palestine. The color of black asphalt is dark brown to black and shiny.

[0118] Black asphalt has a softening point (ring and ball) between 145°C and 195°C; an acid value of 2.3; and a density of 1.03 to 1.15 g / cm3. Black asphalt is soluble in carbon disulfide and aromatic compounds, less soluble in fatty oils and mineral oils. Black asphalt tends to thicken in solution when stored, with lower alcohols and glycols acting as diluents, and black asphalt is only partially soluble in ketones and some glycol ethers.

[0119] The approximate elemental composition of black asphalt is 80% to 90% (such as 85%) carbon by weight, between 5% and 15% (such as 10%) hydrogen by weight, between 1% and 5% (such as 2.5%) nitrogen by weight, between 0.5% and 2.5% (such as 1.5%) oxygen by weight and between 0.1% and 1% (such as 0.3%) sulfur by weight. Black asphalt contains 40% to 70% (about 50% to 65%) asphaltenes by weight, 30% to 50% (such as 35% to 45%) resins by weight, 0.5% to 10% (such as 1% to 5%) oils by weight and 0.05% to 0.5% (such as 0.2%) ash by weight. As the softening point increases, the proportion of asphaltene in the resin increases, and the proportion of oil decreases.

Its acid value is between 50 and 70, and its saponification value is 60-90; Mp is about 105°C (capillary).

[0170] o) Myrrh

[0171] Myrrh is a modern tree resin derived from various species of the genus Commiphora. The resin originates from southern Arabia and Somalia and was known in biblical times. Myrrh oozes from the plant in the form of milk and dries to form beads, which are then collected. Myrrh is in the form of irregular round pearls or crumbs, which are orange-chestnut brown in color with lighter areas and a bitter taste. A variety of myrrh oils can be found, which contain up to 10% myrrh (a mixture of terpenes and sesquiterpenes).

[0172] p) Sandra

[0174] q) Shellac

[0175] Shellac is a modern resin of animal origin produced in India and Thailand. Shellac is produced by female cochineal beetles of species lac insects living in the forests of Southeast Asia (particularly Assam and Thailand). This insect settles on the trunks of trees (ficus and castanea) and uses the resin secreted by them to fix themselves. They are harvested from empty shells (Coccus lacca or Laccifer lacca) from certain trees. Resin is then secreted from the empty shell juice. The word "laksham" means 100,000, because thousands of these shells cover branches (producing the term sticklac). Harvesting is carried out twice a year (April-May and November-December). Shellac contains pure shellac between 50% and 90% (preferably 60% to 80%) by weight and shellac wax of 1% to 10% (preferably 4% to 6%) by weight in particular. Purified resins, also known by the name shellac beads, contain 80 to 95% by weight (preferably 85 to 90%) of pure shellac, as well as 2 to 10% by weight (preferably 5 to 8%) of shellac wax and 0.5 to 4% by weight (preferably 2 to 3%) of impurities. The purified resins can be dewaxed by dissolving them in aqueous sodium carbonate solution or by selective dissolution with certain solvents. Shellac can be treated with alkali metal or alkaline earth metal hypochlorites, in particular to obtain a light color.

[0176] Shellac comes in the form of bright orange or brown, shiny, transparent flakes. The various grades are India button (handmade) and shellac flakes; machine-processed shellac flakes, with or without wax; bleached shellac; and special shellac (water-soluble). Special shellac has been pre-treated with alkaline agents or amines and can be dissolved in water.

[0177] Shellac has an Mp of 65°C-77°C; an acid number of 67 to 90; and a saponification number between 190 and 260. Shellac is soluble in ethanol, glycol ethers, acetic acid, and alkaline water, and is insoluble in aliphatic and aromatic compounds. In alcohol-based solutions, shellac attacks iron. Some shellacs lose their solubility (over many years) due to polycondensation. The resin contains a hydroxycarboxylic acid with five hydroxyl groups, causing polycondensation.

[0178] r) Styrax (Styrax balsam)

[0179] Styrax or styrax balsam is a modern resin isolated from the bark of the Liquidambar orientali tree (Hamamelidaceae) produced in Asia Minor. Styrax is obtained from the living tree once it has been injured.

[0180] Styrax is commonly known as benzoic acid resin. It is aromatic, semi-solid, and has a yellow-brown color. Styrax contains a large amount of cinnamic acid and its derivatives. The acid value of Styrax is about 105.

[0181] s) Venetian turpentine (larch, turpentine essence)

[0182] Modern Venetian turpentine resin is extracted from Larix europaea, a tree found in Europe.

[0183] t) Rosin

[0184] Preferably, the natural resin is selected from rosin. Rosin is a modern resin from renewable resources and may be modified (eg esterified, hydrogenated, substituted).

[0185] Rosin gum is preferably purified and distilled from the balsam of various pine essences (up to 80 different species).

[0186] The composition of rosin is determined by climate, soil composition and other plant and meteorological factors. For example, rosin derived from the following may be mentioned: Pinus austriaca (black pine) Austria, Central America, Caribbean (slash pine), United States, Caribbean, Pinus koraiensis Japan, Pinus elliottii United States, Pinus mediterraneanus (Aleppo pine) Greece, Portugal, Spain, Pinus longifolia India, Pinus maritime (seaside pine) France, Spain, Portugal, Pinus massoniana (Chinese red pine) China, Pinus kalimantanensis Indonesia, Myanmar, Philippines, Pinus nigra (black pine) Austria, Pinus ovata Central America, Honduras, Pinus rapa (swamp pine) United States, (long leaf pine), false white pine Central America, Mexico, Pinus scoparia (Scots pine) Germany, Poland, Pinus sutchuenensis China, Pinus yunnanensis China.

[0187] The average composition is about 70% to 75% rosin and 20% to 25% turpentine essence.

[0188] Wood rosin[8050-09-7]

[0189] Rosin is sourced from tree stumps in the United States that have been left above ground for at least 10 years to obtain the resin-rich heartwood.

[0190] Pine stumps contain between 10 and 30% (about 19%) rosin by weight, between 1 and 10% (preferably 4%) turpentine by weight, between 1 and 10% (preferably 4%) resins insoluble in petroleum ether by weight, between 20 and 30% (preferably 23%) water by weight and between 40 and 60% (preferably 50%) cellulose and lignin types by weight.

[0191] According to a specific embodiment of the present invention, the resin is selected from rosin.

[0192] u) Tall oil rosin (rosin and rosin acid esters) [8052-10-6]

[0193] Tall oil rosin generally contains small amounts of higher fatty acids, in particular fatty acids having a carbon number greater than or equal to 6 carbon atoms. According to one embodiment, the tall oil rosin does not contain oxocarboxylic acids. Tall oil rosin is particularly soluble in organic solvents.

[0194] The rosin resin of the present invention specifically includes abietic acid which belongs to terpene. Abietic acid is used as an example to explain the numbering of carbon atoms in the abietic acid molecule.

[0195] Abietic acid has the molecular formula C 20 H 30 O2, and therefore belongs to the diterpene family (four isoprene units). There are a large number of isomers of tricyclic abietic acid, which differ in the position of the two double bonds.

[0196] Advantageously, the resin according to the invention is chosen from gum rosins obtained by notching on living trees, wood rosins extracted from pinewood or stumps and tall oil obtained from by-products originating from paper production ("tall oil rosin"). Advantageously, the resin comprises abietic acid, preferably mainly chosen from acids of the abietic and pimaric acid type, and in particular chosen from levorotatory pimaric acid, neoabietic acid, abietic acid, dehydroabietic acid, tetrahydroabietic acid, dihydroabietic acid, dextrorotatory pimaric acid, isodextrorotatory pimaric acid or palustric acid, and mixtures thereof.

[0197] Rosin derivatives may in particular result from the polymerization, hydrogenation and / or esterification (for example with polyols such as ethylene glycol, glycerol or pentaerythritol) of rosin acids. Examples that may be mentioned include the rosin esters sold under the references Foral 85, Pentalyn H and Staybelite Ester 10 by Hercules; Sylvatac 95 and Zonester 85 by Arizona Chemical or Unirez 3013 by Union Camp.

[0198] According to one embodiment of the invention, the resin is selected from rosinates (salts of alkaline agents of rosin acid, in particular salts of alkali metals such as sodium or potassium, alkaline earth metals such as calcium, or metals such as zinc or magnesium).

[0199] According to another preferred embodiment of the invention, the resin is chosen from rosin acid esters, in particular esters of rosin acid as defined above with (C1-C6)alkanols, polyhydroxy (C1-C6)alkane polyols such as glycerol, pentaerythritol and mixtures thereof, more preferably chosen from glycerol rosinate sold under the name RESIESTER GUM A 35, glycerol rosinate as a mixture with hydrogenated vegetable oil and / or castor oil (hydrogenated vegetable oil, castor oil, glycerol rosinate sold by EFP BIOTEK), pentaerythritol rosinate sold under the names RESIESTER N 35S and RESIESTER 80.

[0200] According to another embodiment of the present invention, the resin is selected from poly(carboxy)(C2-C6)alkane or poly(carboxy)(C2-C6)olefin adducts, in particular adducts of maleic acid and rosin acid.

[0201] According to another embodiment of the invention, the resin is selected from phenol-modified rosins, in particular those modified by (C1-C4) alkylenephenols or diphenols, which are optionally substituted by one or more (C1-C4) alkyl groups such as methyl or tert-butyl, more particularly rosins modified by 4-tert-butylphenol and 4,4'-isopropylidene diphenol (bisphenol A).

[0202] According to another embodiment of the invention, the resin is selected from dimerized rosins, in particular those in which abietic acid is polymerized. The rosin preferably contains more than 50% dimer acid and is therefore called dimerized rosin. According to one embodiment, the rosin is polymerized and contains 30 to 90% dimer acid by weight (in particular at least 40%, 60% or 80% dimer acid).

[0203] According to a preferred embodiment of the invention, the resin is selected from hydrogenated rosin. Double bonds, in particular those of acids such as abietic acid, are subject to oxidation, which can be eliminated by hydrogenation. Of course, the resins of the invention can be esterified, salified, adducted, phenol-modified and / or dimerized and additionally hydrogenated.

[0204] According to a preferred embodiment, the resin contains at least one ester of rosin acid selected from the group consisting of glycerol rosinate, pentaerythritol rosinate, silicone rosinate, diethylene glycol rosinate, hydrogenated rosinate dilinoleyl dimer, dipentaerythritol hexahydroxystearate / hexastearate / hexarosinate, glyceryl dibehenate / hydrogenated rosinate, glyceryl diisostearate / hydrogenated rosinate, trihydrogenated glycerol rosinate, glycol rosinate, hydrogenated methyl rosinate, methyl rosinate, hydrogenated pentaerythritol rosinate, hydrogenated triethylene glycol rosinate and mixtures thereof.

[0205] According to a particular embodiment, the resin of the invention is chosen from hydrogenated pentaerythritol rosinate (pentaerythritol hydrogenated rosinate), hydrogenated methyl rosinate (methyl hydrogenated rosinate) sold under the name SYMRISE BIO4326.

[0206] Furthermore, the resin of the invention may be mixed with a fatty substance c), in particular a wax or a butter, as defined below. Mention may be made of mixtures of glyceryl rosinate with one or more fatty substances c), in particular chosen from waxes or butters, such as mixtures with shea butter or olive oil, such as (glyceryl rosinate, castor oil, hydrogenated vegetable oil), shea butter glyceryl rosinate, OLEA EUROPEAA (olive) oil unsaponifiable glyceryl rosinate, OLEA EUROPEAA (olive) oil unsaponifiable sold by SHEA BUTTER & GLYCERYL ROSINATE & OILS.

[0207] v) Resins extracted from plant waxes

[0208] Natural plant waxes themselves are not considered resins. Although they are among the substances secreted / excreted by plants and naturally contain very low levels of resins, they contain less than 30% terpenes by weight relative to the total weight of the wax. For example, carnauba wax is naturally secreted by the leaves of the palm tree (Copernica cerifera) to prevent the leaves from dehydrating. Candelilla wax is obtained from a shrub called Euphorbia antisyphilitica originating from northern Mexico. The wax protects the plant from the effects of its environment and prevents excessive evaporation. For example, Candelilla wax is mainly composed of hydrocarbons (about 50%, chains of 29 to 33 carbon atoms), higher molecular weight esters (20% to 29%), free acids (7% to 9%) and resins (12%-14%, mainly triterpene esters).

[0209] However, for the purposes of the present invention, the definition of "natural resin" also includes resins resulting from plant waxes, when they have been previously concentrated, separated or extracted from these waxes, as long as the resinous or terpenic component in question contains the minimum content of terpenes required by the invention (30% by weight relative to the total weight of the component). Mention may in particular be made of the Candelilla resin with the INCI name: EUPHORBIA CERIFERA (Candelilla) wax extract, sold under the name CANDELILLA RESIN E-1 by JAPAN NATURAL PRODUCTS (pure 100% resin, extracted from the corresponding wax). Document WO 2013 / 147113 A1 also relates to carnauba resins, i.e. terpene resins extracted from carnauba wax, which have physical properties similar to those of the natural resins traditionally described, such as a softening temperature instead of a melting temperature, which distinguishes the resin from the wax.

[0210] Table 1 of Examples shows some characteristic differences between waxes according to the invention and resins with respect to their thermal properties.

[0211] Resins have a softening point and a glass transition temperature, but not a melting temperature.

[0212] The opposite applies to waxes, which have a melting temperature.

[0213] The resin is preferably chosen from resins j), k) and t) as defined previously, and resins v) extracted from waxes, in particular candelilla or carnauba wax, and mixtures thereof.

[0383] These sizes were obtained using the MasterSizer from Malvern. The measurement is carried out by static light scattering using a commercial particle size analyzer of the type 1000, making it possible to determine the particle size distribution of all particles over a wide range that can extend from 0.01 μm to 1000 μm. The data are processed based on the standard Mie scattering theory. This theory is most applicable to size distributions ranging from submicron to multimicron; it allows the effective particle size to be determined. This theory is described in particular in the following publication: Van de Hulst, HC, Light Scattering by Small Particles, Chapters 9 and 10, Wiley, New York, 1957.

[0384] D

[50] represents the maximum dimension possessed by 50% by volume of the particles.

[0385] In the context of the present invention, mineral pigments are more particularly iron oxide and / or titanium dioxide. By way of example, mention may be made more particularly of the mineral pigments produced, for example, by MIYOSHI KASEI under the reference number Sold titanium dioxide and iron oxide coated with aluminum stearoyl glutamate.

For the purposes of the present invention, the term "stable" means the absence of the effect that the color changes with the viewing angle or also changes in response to temperature changes.

[0394] For example, such materials can be chosen from particles with metallic shimmer, goniochromatic colorants, diffractive pigments, thermochromic agents, optical brighteners, and also fibers, in particular interference fibers. Of course, these different materials can be combined in order to provide a simultaneous display of two effects, indeed even with novel effects according to the invention.

[0409] According to a particular form of the invention, the composition according to the invention comprises at least one pigment coated with at least one lipophilic or hydrophobic compound, and is in particular as described in detail below.

[0410] This type of pigment is particularly advantageous, considering that it can be combined with large amounts of water in relatively large quantities. Furthermore, in the case of treating them with hydrophobic compounds, they show a major affinity for the oily gel phase which can then transport them.

[0411] Of course, the composition according to the invention can concurrently contain uncoated pigments.

[0412] The coating may also comprise at least one additional non-lipophilic compound.

[0413] For the purposes of the present invention, "coating" of a pigment according to the present invention generally means a total or partial surface treatment of the pigment with a surfactant which is absorbed, adsorbed or grafted onto the pigment.

[0414] The surface treated pigments can be prepared according to chemical, electrical, mechanochemical or mechanical surface treatment techniques well known to those skilled in the art. Commercial products can also be used.

[0415] Surfactants can be absorbed, adsorbed or grafted onto the pigment by solvent evaporation, chemical reaction and covalent bond formation.

[0416] According to one variant, the surface treatment consists of coating with pigments.

[0417] The coating may represent 0.1% to 20% by weight and in particular 0.5% to 5% by weight relative to the total weight of the coated pigment.

[0418] The coating can be produced, for example, by absorbing a liquid surfactant onto the surface of the solid particles by simply mixing the particles with said surfactant under stirring, optionally with heating, before incorporating the particles into the other ingredients of the cosmetic or care composition.

[0419] The coating can be produced, for example, by chemical reaction of a surfactant with the surface of the solid pigment particles and formation of covalent bonds between the surfactant and the particles. This method is described in particular in patent US 4,578,266.

[0420] Chemical surface treatment may include diluting the surfactant in a volatile solvent, dispersing the pigment in this mixture, and then slowly evaporating the volatile solvent so that the surfactant is deposited at the surface of the pigment.

[0431] A method for surface treating a pigment with polymethylhydrogensiloxane comprises dispersing the pigment in an organic solvent and then adding a silicone compound. When the mixture is heated, a covalent bond is formed between the silicone compound and the pigment surface.

[0432] According to a preferred embodiment, the silicone surfactant may be a non-elastomeric organopolysiloxane, in particular selected from polydimethylsiloxane.

[0548] i) Hydrophobic Silica Aerogel

[0549] Hydrophobic silica aerogels are porous materials obtained by replacing the liquid component of silica gel with air, in particular by drying. They are usually synthesized by the sol-gel process in a liquid medium and then dried, usually by extraction with a supercritical fluid, the most commonly used supercritical fluid being supercritical CO2. This type of drying makes it possible to avoid shrinkage of the pores and the material. The sol-gel process and various drying operations are described in detail in Brinker CJ and Scherer GW, Sol-Gel Science, New York, Academic Press, 1990.

[0550] The hydrophobic silica aerogel used according to the invention is preferably a silica silylate aerogel (INCI name: SILICA SILYLATE).

[0551] The term "hydrophobic silica" means that the surface of the silica is treated with a silylating agent, for example, a silane halide such as an alkylchlorosilane, a siloxane, in particular a dimethylsiloxane such as hexamethyldisiloxane or a silazane, so as to form a hydrophobic silica with Si-R n Any silica having silyl groups functionalized with OH groups, such as trimethylsilyl.

[0552] Regarding the preparation of hydrophobic silica aerogel particles surface-modified by silylation, reference may be made to US Pat. No. 7,470,725.

[0553] Aerogel particles formed from hydrophobic silica which has been surface-modified with trimethylsilyl groups (trimethylsiloxylated silica) will in particular be used.

[0554] The term "hydrophobic aerogel particles" means particles of any aerogel type which exhibit a water absorption capacity at the wet point of less than 0.1 ml / g, ie less than 10 g of water per 100 g of particles.

[0555] The absorption capacity measured at the wet point and indicated as WP corresponds to the amount of solvent (expressed in grams or milliliters) that needs to be added to 1 g of granules in order to obtain a homogeneous paste. It is measured according to the "wet point" method or the method for determining the solvent (water or oil) absorption of powders described in standard NF T 30-022. It corresponds to the amount of solvent adsorbed onto the available surface of the powder and / or absorbed by the powder, measured by the wet point measurement method described below:

[0556] A glass plate (25×25 mm) is placed on a balance, an amount w of 1 g of powder is weighed out on the glass plate and then a solvent (e.g. water or isononanoate) is added dropwise. The solvent is gradually added to the powder, all kneading regularly (every 3 to 4 drops) using a spatula. When a homogeneous paste is obtained, the addition of solvent is stopped. This paste must be able to be spread on the glass plate without breaking or forming lumps. The weight of solvent required to obtain the wet point is recorded. The average of three tests is taken. Since the density of the solvent is known, the volume Vs (in ml) of the solvent used is deduced from it. The solvent absorption rate corresponds to the ratio Vs / w.

[0557] Preferably, the hydrophobic silica aerogel particles according to the invention preferably have an oil absorption capacity measured at the wet point ranging from 5 to 18 ml / g, preferably from 6 to 15 ml / g and better still from 8 to 12 ml / g.

[0558] The hydrophobic silica aerogel particles used in the present invention preferably have a particle size in the range of 200 to 1500 m 2 / g, preferably 600 to 1200m 2 / g and better still a specific surface area per unit weight (SM) of 600 to 800 m2 / g, and a size expressed as a volume average diameter (D[0.5]) of less than 1500 μm and preferably in the range of 1 to 30 μm, preferably 5 to 25 μm, better still 5 to 20 μm and even better still 5 to 15 μm.

[0559] The specific surface area per unit weight can be determined by the nitrogen adsorption method known as the BET (Bruno-Emmett-Teller) method, which is described in The Journal of the American Chemical Society, Vol. 60, p. 309, February 1938 and corresponds to the international standard ISO 5794 / 1 (Annex D). The BET specific surface area corresponds to the total specific surface area of ​​the particles under consideration.

[0560] The size of the aerogel particles according to the invention can be sized using a Mastersizer from Malvern The measurements are made by static light scattering using a commercial particle size analyzer of the type 1000. The data are processed based on the Mie scattering theory. This theory, which is accurate for isotropic particles, allows the determination of the effective particle size in the case of non-spherical particles. This theory is described in particular in the following publication: Van de Hulst, HC, Light Scattering by Small Particles, Chapters 9 and 10, Wiley, New York, 1957.

[0561] The hydrophobic silica aerogel particles used in the present invention may advantageously have a hydrophobicity in the range of 0.02 g / cm 3 Up to 0.10g / cm 3 And preferably 0.02g / cm 3 Up to 0.08g / cm 3 The tap density.

[0562] In the context of the present invention, this density can be assessed according to the following scheme, known as the tap density scheme:

[0563] 40 g of powder were poured into a measuring cylinder; the measuring cylinder was then placed in a Stav from Stampf Volumeter. machine; the cylinder is then subjected to a series of 2500 tapping actions (this operation is repeated until the volume difference between two consecutive tests is less than 2%); the final volume Vf of the tapped powder is then measured directly on the cylinder. The tapped density is determined by the ratio m / Vf, in this case 40 / Vf (Vf is expressed in cm 3 denoted by , and m is denoted by g).

[0564] According to one embodiment, the hydrophobic aerogel particles used in the present invention have a particle size ranging from 5 to 60 μm. 2 / cm 3 , preferably 10 to 50 m 2 / cm 3 And also better 15 to 40m 2 / cm 3 The specific surface area per unit volume (S V ).

[0565] The specific surface area per unit volume is given by the following relationship:

[0566] S V =S M .ρ, where ρ is expressed in g / cm 3 represents the tap density, and S M m 2 The specific surface area per unit weight expressed by % / g is as defined above.

[0567] According to a particular embodiment, the aerogel particles used are inorganic and more particularly hydrophobic silica aerogel particles having the properties previously described.

[0568] As hydrophobic silica aerogel that can be used in the present invention, mention may be made of, for example, the aerogel sold by the company Dow Corning under the name VM-2260 (INCI name: Silica Silylate), the particles of which have an average size of about 1000 microns and a particle size ranging from 600 to 800 microns. 2 / g of specific surface area per unit weight.

[0572] The hydrophobic aerogel particles represent from 0.05% to 10% by weight, preferably from 0.1% to 8% by weight, better still from 0.2% to 5% by weight and more preferably from 0.3% to 3% by weight relative to the total weight of the composition.

[0575] They may be fumed silica.

[0576] These fumed silicas can be obtained by high temperature hydrolysis of volatile silicon compounds in an oxyhydrogen flame, producing finely divided silica. This method makes it possible in particular to obtain hydrophilic silicas with a large number of silanol groups on their surface. The surface of the silica can be chemically modified by chemical reactions, causing a reduction in the number of silanol groups. In particular, the silanol groups can be replaced by hydrophobic groups: hydrophobic silicas are then obtained.

[0577] The hydrophobic group can be:

[0578] (a) trimethylsiloxy groups, which are obtained in particular by treating fumed silica in the presence of hexamethyldisilazane. According to the CTFA (6th edition, 1995), silicas thus treated are called silylated silicas;

[0579] (b) Dimethylsiloxy or polydimethylsiloxane groups, which are obtained in particular by treating fumed silica in the presence of polydimethylsiloxane or dimethyldichlorosilane. According to the CTFA (6th edition, 1995), the silica thus treated is known as dimethylsilylated silica.

[0620] Ethanol (volatile alcohol) and isododecane (volatile oil) were used to dissolve each resin.

[0621] Example 1 - Solubility Test

[0622] Procedure and equipment used for each test:

[0623] Each resin (A, B, C) was dissolved in a mixture of ethanol and isododecane at ambient temperature according to the weight proportion indicated in each row (No. 1 to 21) of Table 1 below.

[0624] plan:

[0625] - Each resin was dissolved in a 20 ml flask at ambient temperature (25° C.) under magnetic stirring at 1200 rpm for 24 hours.

[0626] - The solubility of the resins in volatile cosmetic solvents at ambient temperature was assessed visually and the following solubility scale was established:

[0627] Soluble - transparent solution

[0628] Partially soluble - opaque solution

[0629] Insoluble - fragments of starting material present

[0630] Results of visual assessment of resin solubility

[0631] [Table 3]

[0632]

[0633]

[0634] The mixture of volatile alcohols and volatile alkanes used according to the invention makes it possible to dissolve the natural resins at ambient temperature (25° C.), even for low contents of volatile alcohol (5.56% for glycerol rosinate, 11.1% for Scutellaria septoria resin, 16.67% for Candelilla wax extract).

[0635] Within the ethanol range of between 11.1% and 83.3% ethanol by weight, 5.56% of the Candelilla resin was soluble or at least partially soluble.

[0636] In the ethanol range between 11.1% and 94.4% ethanol by weight, 5.56% of the Aesculus quinata resin was soluble or at least partially soluble.

[0637] 5.56% of glycerol rosinate resin is soluble at between 5.56% by weight and 66.7% by weight of ethanol.

[0638] The percentage contents are by weight relative to the total weight of the ternary composition representing 100%.

[0639] Considering these results, the preferred solubilization range for these three resins is between 11.1% and 66.7% ethanol for 5.56% resin.

[0640] In a 50 / 50 by weight mixture of ethanol and isododecane, the resins were soluble over a concentration range of up to 44.4% for both candelilla and glycerol rosinate resins.

[0641] Comparative test based on wax (Comparative Example 22):

[0642] Testing of 5.56% by weight of candelilla wax (instead of candelilla resin) under the same conditions showed that the wax was insoluble in ethanol or isododecane or any ethanol / isododecane mixture.

[0643] The mixture of volatile alcohol and volatile alkane according to the invention makes it possible to dissolve natural resins and thus optimize the spreading properties of these resins during and after application of the composition.

[0644] Example 2 - Comparative card durability test (in vitro)

[0645] The natural resin compositions dissolved in a mixture of volatile oils and volatile alcohols were evaluated for rub resistance by colorimetric measurement of the dry film before and after abrasion, the test protocol being described in detail below.

[0646] The following coloring starting materials were added to the composition of the example:

[0647] -Organic Pigment Red 7 or

[0648] - Mineral pigment coated iron oxide.

[0649] Colored compositions were produced using a rotor-stator according to the same protocol as above at ambient temperature (25° C.) to incorporate these pigments into each of the compositions tested.

[0650] Scheme for spreading the composition into a film:

[0651] The product is spread on a spreading table (Elcometer 4340Applicator) so that the spreading speed and also the spreading distance can be adjusted. The table is equipped with a suction system connected to a pump so that the support on which the product is spread cannot move. An uncoated contrast card with a black background and a white background (1byko-chart, uncoated N2A, code 2831) is used. The spreading thickness can be adjusted using a square spreader placed on the support so that the platform is set to spread by leveling when it is in operation. Each edge face of the spreader can achieve a spreading with different thicknesses ranging from 25μm to 200μm. The selected thickness is 25μm so as to approach the film thickness in vivo. During spreading, a weight of 960g is added to the spreader. The spreading rate is set to 1" / second, i.e. 2.54cm / s. The film is dried on a heating plate at 34°C and ambient RH for 24 hours.

[0652] Friction resistance test solution:

[0653] The abrasion resistance test was performed by colorimetric measurement of the dry film before and after abrasion. The abrasion was performed by attaching a piece of tissue to the 25 μm spreader edge surface. During abrasion, a weight of 960 g was added to the spreader. The stage speed was set to 2.54 cm / s.

[0654] The color before and after abrasion was measured using a Konica Minolta CM-700d spectrophotometer. The measurement under contact enables the absence of stray light to be guaranteed.

[0655] Selected settings: Aperture 8 mm; Uncertainty: 0.04; SCI / SCE measurement; d / 8° geometry.

[0656] The measurement of the color on two backgrounds (black background BB and white background WB) enables the hiding power of the foundation to be characterized by calculating the contrast ratio (CR%), i.e. YBB / YWB x 100, where YBB and YWB are the brightness values ​​measured on the black background and white background respectively, the higher these values, the greater the hiding power of the foundation.

[0657] To evaluate the friction resistance, the contrast ratio before friction (CR dry deposit, %) and the contrast ratio after wear (CR friction dry deposit, %) were measured respectively. The ratio [CR friction dry deposit / CR dry deposit]*100 as a percentage represents the resistance of the film to friction: the higher the ratio, the greater the resistance of the film to friction.

[0658] Note: For each contrast value, at least 2 contrast cards were used for each composition, and 3 CR measurements were performed on each card. Therefore, each CR value represents the average of 6 measurements.

[0659] Results of the abrasion resistance of the tested compositions

[0660] [Table 4]

[0661]

[0662] *The coated iron oxides have the following INCI names: Iron Oxides (and) Disodium Stearoyl Glutamate (and) Aluminum Hydroxide.

[0663] Deposits based on candelilla resins have better rub resistance when containing 1% by weight of resin in the composition. For film deposits made from compositions according to the invention containing at least 2% by weight of resin (Example 26), the rub resistance is high (at least 60%). For film deposits produced from compositions according to the invention containing at least 7.5% by weight of resin (Example 24), the rub resistance is particularly high (at least 80%) for the same content of volatile alcohol (Example 24: 41.25%) and volatile oil (Example 24: 41.25%), see also Example 29 using other pigments.

[0664] Example 3 - Adhesion Test

[0665] Protocol for measuring viscosity

[0666] The support used was a strip of "Supplale": synthetic leather sheet (polyurethane adhesively bonded to polyester cotton fabric), white in colour and having dimensions of 150 mm x 25 mm, sold under the name Supplale, code DFSUP15025B, supplier Soudotique).

[0667] The product is deposited on the Supplale strip over a length of 10 cm using an applicator so as to obtain a uniform deposit (the applicator is passed 4 times over the entire length, re-immersing the applicator in the product between passes). The support with the sample is placed on a plate thermostatically controlled at 32°C and ambient RH to dry for 1 hour. Next, the specimen is placed on the base of a texture analyzer or on a metal plate provided with double-sided adhesive tape in order to fix the sample. The viscosity is measured using a TAXT2 plus texture analyzer. A 20 mm diameter tape containing a circle of fixed white The axis (tip) is positioned on the texture analyzer.

[0668] The parameters for the compression test regarding retention over time were as follows: approach speed (or pre-speed): 1 mm / s; speed (starting from contact detection): 0.5 mm / s; force: 800 g; hold time: 5 s; return speed (or post-speed): 40 mm / s.

[0669] The stickiness is characterized by the work of detachment measured during the unloading (stretching phase) corresponding to the integral of the curve under the time axis. This work is expressed as positive joules per square meter. The lower the value of the work measured, the less sticky the deposit is.

[0670] [Table 5]

[0671]

[0672]

[0673] The viscosity limit was determined to be 1.5 J / m2. Beyond this, the deposit became noticeably sticky.

[0674] All deposits showed a lack of tack after the films had dried (at 60 min).

[0675] The test results in the above table show that the films deposited from each of the compositions according to the present invention (Example 30 and Example 31) had no tacky effect (0.12 J / m2).

[0679] Candelilla resin was dissolved in ethanol, isododecane and / or cyclotetrasiloxane, and a mixture of undecane and tridecane (Cetiol UT from BASF) at ambient temperature according to the same protocol as above (1200 rpm for 24 hours at ambient temperature (25° C.)) according to the weight proportions shown in Table 6. The solubility of the resin in volatile cosmetic solvents at ambient temperature was visually evaluated.

[0680] Compared with Example 34 or Example 35 based on at least 10% volatile silicone oil, it was found that for Example 32 and Example 33, the natural resin Dissolve Easier and faster.

[0681] Then the coloring ingredients were added to the composition of Table 6 (talc coated with aluminum stearoyl glutamate, titanium dioxide and iron oxide red, iron oxide yellow and iron oxide black, manufactured by Miyoshi Chemicals Co., Ltd. under the reference number Sale).

[0682] Colored compositions were produced using a rotor-stator according to the same protocol as above at ambient temperature (25° C.) to incorporate these pigments into each of the compositions tested.

[0683] Membrane evaluation:

[0684] After spreading the composition into a film (same protocol as above), the deposits based on Examples 32 and 33 were compared and found to be visually more uniform than Examples 34 or 35. The abrasion resistance in the case of Examples 32 and 33 (according to the same protocol as above) was found to be higher.
