Description

Title of the invention: POWDERY COMPOSITION WITH GOOD SEBUM ABSORPTION AND GOOD TEXTURE technical field

[0001] The present invention relates to a powder composition suitable for cosmetic treatments of keratinous materials such as skin. PRIORITY OF THE TECHNOLOGY

[0002] Skin makeup cosmetics can generally be used to give an attractive color to the skin, especially the face, but can also be used to mask skin imperfections, such as redness, marks and wrinkles.

[0003] Some makeup cosmetics may be in the form of a powder cosmetic composition. A powder cosmetic composition generally comprises a high powder content, for example, at least about 70% by weight of powders, relative to the total weight of the composition. DISCLOSURE OF THE INVENTION

[0004] Some conventional powder cosmetic compositions do not offer sufficiently long-lasting cosmetic effects on the skin. For example, if such a conventional powder cosmetic composition is used over a long period, it may be difficult for the composition to keep the skin matte and / or maintain its color unchanged for an extended period due to the sebum, including oil, that is secreted onto the skin over time. Given their ease of use, long-lasting cosmetic effects are desirable for powder cosmetic compositions. Thus, good sebum absorption capacity is required for long-lasting cosmetic effects from powder cosmetic compositions.

[0005] In addition, a good texture is also required for powdered cosmetic compositions.

[0006] However, it was difficult for some conventional powdered cosmetic compositions to have both good sebum absorption capacity and a good texture. In general, powdered cosmetic compositions with good sebum absorption capacity tend to have a poor texture, while powdered cosmetic compositions with a good texture tend to have a low sebum absorption capacity.

[0007] Thus, one objective of the present invention is to propose a composition powdery which can have both a good sebum absorption capacity and a good texture.

[0008] The above objective can be achieved by a composition, preferably a cosmetic composition and, even better, a cosmetic composition for the makeup of keratinous materials such as skin, comprising:

[0009] (a) at least one particle having

[0010] a wetting point for the oil of at least 150 ml / 100 g, and preferably of at least 180 ml / 100 g;

[0011] and

[0012] (b) at least one charge other than the (a) particle,

[0013] in which

[0014] the total quantity of the (a) particle(s) and the (b) charge(s) is greater than 80% by weight, preferably greater than 85% by weight and, even better, greater than 90% by weight, relative to the total weight of the composition.

[0015] The particle (a) may have a wetting point for water of at least 200 ml / 100 g, preferably at least 250 ml / 100 g and, even better, at least 300 ml / 100 g.

[0016] The ratio between the wetting point for water and the wetting point for oil of the (a) particle may be less than or equal to 5, preferably less than or equal to 4 and, even better, less than or equal to 2.

[0017] The average size of the particle (a) may be 50 µm or less, preferably 30 µm or less, and even better 10 µm or less.

[0018] The (a) particle may be porous.

[0019] The (a) particle may comprise at least one polysaccharide, preferably cellulose.

[0020] The quantity of the (a) particle(s) in the composition according to the present invention can be from 1% to 40% by weight, preferably from 5% to 35% by weight and, even better, from 10% to 30% by weight, relative to the total weight of the composition.

[0021] The charge (b) may have been coated.

[0022] The (b) filler may be selected from the group consisting of micas, surface-treated micas, and mixtures thereof, preferably selected from the group consisting of muscovite, synthetic fluorophlogopite, surface-treated synthetic fluorophlogopite, and a mixture thereof, and better still, selected from the group consisting of muscovite, synthetic fluorophlogopite, methylhydrogen polysiloxane-treated synthetic fluorophlogopite, and a mixture thereof.

[0023] The quantity of the (b)filler(s) in the composition according to the present invention can be from 40% to 80% by weight, preferably from 45% to 75% by weight and, even better, from 50% to 70% by weight, relative to the total weight of the composition.

[0024] Thus, the quantity of silica powder in the composition according to the present invention may be less than 3% by weight, preferably less than 2% by weight and, better still, less than 1% by weight, relative to the total weight of the composition.

[0025] Thus, the quantity of a resin or plastic powder in the composition according to the present invention can be less than 3% by weight, preferably less than 2% by weight and, even better, less than 1% by weight, relative to the total weight of the composition.

[0026] The composition according to the present invention may be in the form of a loose powder, or a compact or pressed powder, preferably in the form of a loose powder.

[0027] The present invention also relates to a cosmetic care method for keratinous materials such as skin, comprising:

[0028] the application on keratin fibers of the composition according to the present invention.

[0029] The present invention may also relate to a use of (a) a particle having:

[0030] a wetting point for the oil of at least 150 ml / 100 g and preferably of at least 180 ml / 100 g

[0031] in a composition comprising (b) at least one filler other than (a) particle, wherein the total quantity of (a) particle(s) and (b) filler(s) is greater than 80% by weight, preferably greater than 85% by weight and, even better, greater than 90% by weight, relative to the total weight of the composition,

[0032] to improve both sebum absorption and the texture of the composition. Best embodiment of the invention

[0033] After careful research, the inventors discovered that it is possible to provide a powder composition that can have both a good sebum absorption capacity and a good texture.

[0034] The composition according to the present invention is a composition, preferably a cosmetic composition and, even better, a cosmetic composition for the makeup of keratinous materials such as skin, comprising:

[0035] (a) at least one particle having

[0036] a moisture point for the oil of at least 150 ml / 100 g, and preferably of at least 180 ml / 100 g;

[0037] and

[0038] (b) at least one charge other than the (a) particle,

[0039] in which

[0040] the total quantity of the (a) particle(s) and the (b) charge(s) is greater than 80% by weight, preferably greater than 85% by weight and, even better, greater than 90% by weight, relative to the total weight of the composition.

[0041] Since the total quantity of the (a) particle(s) and the (b) filler(s) is greater than 80% by weight, relative to the total weight of the composition according to the present invention, the composition according to the present invention can be considered as a powder composition.

[0042] The composition according to the present invention can offer both good oil / sebum absorption capacity and a good texture. Consequently, the composition according to the present invention can offer both long-lasting cosmetic effects against sebum secreted over time on the skin and a comfortable feel during use. Thus, the composition according to the present invention can offer good suitability for use:

[0043] If the particle (a) has a water wetting point of at least 200 ml / 100 g, preferably at least 250 ml / 100 g, and, even better, at least 300 ml / 100 g, the composition according to the present invention can also have good water absorption capacity and, consequently, it can also offer good water resistance. Therefore, in this case, the composition according to the present invention can also offer lasting cosmetic effects against rain or perspiration.

[0044] If the quantity of a silica powder, in particular a porous silica powder, in the composition according to the present invention is less than 3% by weight, relative to the total weight of the composition, the risk of inhalation of the silica powder can be reduced or avoided.

[0045] If the quantity of a resin or plastic powder, in particular a polyamide powder and a poly(meth)acrylate powder such as a Nylon® powder and a polymethyl methacrylate powder, in the composition according to the present invention is less than 3% by weight, relative to the total weight of the composition, environmental contamination by the resin or plastic powder can be reduced or avoided.

[0046] Each of the present inventions will be described in detail below.

[0047] [Composition]

[0048] The composition according to the present invention comprises:

[0049] (a) at least one particle having

[0050] a wetting point for the oil of at least 150 ml / 100 g, and preferably of at least 180 ml / 100 g;

[0051] and

[0052] (b) at least one charge other than the (a) particle,

[0053] in which

[0054] the total quantity of the (a) particle(s) and the (b) charge(s) is greater than 80% by weight, preferably greater than 85% by weight and, even better, greater at 90% by weight, relative to the total weight of the composition.

[0055] (Particle)

[0056] The composition according to the present invention includes (a) at least one particle with specific properties. If two or more particles are used, they may be identical or different.

[0057] The (a) particles can take the form of a powder.

[0058] The (a) particle has a wetting point for oil of at least 150 ml / 100 g, and preferably of at least 180 ml / 100 g, and / or preferably of 1500 ml / 100 g or less.

[0059] The expression "oil wetting point" in the specification refers to an amount of oil required to make a target powder completely wet, which can be recognized, in particular, by the formation of a paste with the target powder.

[0060] The wetting point for the oil can be determined in accordance with ISO-787 / 5-1980, which corresponds to JIS K 5101-13-1, provided that isononyl isononanoate is used instead of linseed oil.

[0061] Specifically, the wetting point for the oil can be determined by the following protocol. 1. 2 g of a target powder are mixed using a spatula on a plate of glass while adding oil, especially linear ester oil, such as isononyl isononanoate (WICKENOL 151 / ALZO). 2. When the target powder becomes completely wet and begins to form a paste, the weight of the added oil is determined as the weight at the wetting point. 3. The wetting point for the oil is calculated from the following equation: wetting point for the oil (ml / 100 g) = {(weight at the wetting point) / 2 g]X100 / density of the oil.

[0062] As the (a) particle has a wetting point for oil of at least 150 ml / 100 g, the composition according to the present invention including (a) particle may have a good capacity for absorbing oil / sebum. Therefore, the composition according to the present invention may offer lasting cosmetic effects against sebum secreted over time on the skin.

[0063] Sebum contains oil. Thus, the higher the wetting point for oil, the better the absorption capacity of sebum.

[0064] It is preferable that the (a) particle also have a wetting point for water of at least 200 ml / 100 g, preferably of at least 250 ml / 100 g, better still, of at least 300 ml / 100 g, even better still, of at least 350 ml / 100 g and / or preferably, of 1500 ml / 100 g or less.

[0065] Similarly, the expression "water wetting point" in the specification refers to the amount of water required to make a target powder completely wet, which can be recognized, in particular, by the formation of a paste with the target powder.

[0066] The wetting point for the oil can also be determined in accordance with ISO-787 / 5-1980, which corresponds to JIS K 5101-13-1, provided that water is used instead of linseed oil.

[0067] In particular, the mooring point for the water can be determined by the following protocol. 1. 2 g of a target powder are mixed using a spatula on a plate of glass while adding water with a density of 0.998 g / ml. 2. When the target powder becomes completely wet and begins to form a paste, the weight of the added water is determined as the weight at the wetting point. 3. The wetting point for water is calculated from the following equation: Wetting point for water (ml / 100 g) = {(wetting point weight) / 2 g]X100 / density of water.

[0068] If (a) the particle has a wetting point for water of at least 200 ml / 100 g, the composition according to the present invention including (a) the particle may have a good water absorption capacity. Therefore, the composition according to the present invention may offer long-lasting cosmetic protection against water, such as that provided by rain or perspiration.

[0069] The higher the wetting point for water, the better the resistance to rain or sweat.

[0070] It is preferable that the ratio of the water wetting point / oil wetting point of the (a) cellulose particle used for the present invention be 5 or less, preferably 4 or less, better still 3 or less and, even better still, 2 or less, and preferably 0.1 or more.

[0071] The particle size of (a) particle is not limited. However, it is preferable that the average size of particles (a) be 50 pm or less, preferably 30 pm or less, better still 10 pm or less, and even better 2 to 5 pm.

[0072] The particle size of (a) particle corresponds to a primary particle size. Furthermore, particle size here refers to an average size or particle average, which may be a volume average size, which can be determined, for example, by a laser diffraction particle size analyzer.

[0073] It is preferable that 90% or more of the volume of (a) particles have an average (primary) particle size ranging from 0.1 to 10 pm, preferably from 0.5 to 8 pm and, even better, from 1 to 7 pm. If 90% or more of the volume of (a) particles has an average (primary) particle size ranging from 1 to 7 pm, optical effects due to the particles can also be obtained.

[0074] It is preferable that the ratio between the longest diameter / shortest diameter of (a) particle be in the range of 1.0 to 10, preferably from 1.0 to 5 and, even better, from 1.0 to 3. It is preferable that (a) particle be spherical, preferably with a ratio of the longest diameter / shortest diameter of 1.0 to 1.1.

[0075] The (a) cellulose particle may be porous or non-porous. However, it is preferable that the (a) particle be porous.

[0076] The porosity of the (a) particle can be characterized by a specific surface area of ​​0.05 m2 / g to 1,500 m2 / g, better still of 0.1 m2 / g to 1,000 m2 / g, and even better still of 0.2 m2 / g to 500 m2 / g according to the BET method.

[0077] The (a) particle may comprise any organic or inorganic matter, which is not limited to, and may be selected from polysaccharides such as cellulose; boron compounds such as boron nitride; metallic compounds such as alumina, barium sulfate and magnesium carbonate; perlites and mixtures thereof.

[0078] It is preferable that the (a) particle comprise at least one polysaccharide.

[0079] The polysaccharide may be selected from alginic acid, guar gum, xanthan gum, gum arabic, arabinogalactan, carrageenan, agar-agar, karaya gum, tragacanth gum, tara gum, pectin, locust bean gum, cardolan, gellan gum, dextran, pullulan, hyaluronic acid, cellulose and its derivatives, and mixtures thereof. Cellulose and its derivatives are preferable. Cellulose is even more preferable.

[0080] It is preferable that (a) particle comprise cellulose. It is preferable that (a) particle be made of cellulose. In other words, it is preferable that (a) particle be a cellulose particle. Thus, (a) particle need not be a composite particle including cellulose and any other material.

[0081] In the present invention, the cellulose that can be used is not limited by types of cellulose such as cellulose I, cellulose II, or the like. As a cellulose that can be used as a material for (a) the particle for the present invention, type II cellulose is preferable.

[0082] The cellulose that can be used as material for the (a) particle can be in any particle form, in particular, a spherical particle.

[0083] The cellulose particle, preferably a spherical cellulose particle, can be prepared, for example, as follows. 1. A suspension of calcium carbonate, as an aggregation inhibitor, is added to an alkaline aqueous solution of water-soluble anionic polymer, and then stirred. 2. The viscose and the aqueous solution obtained in the preceding (1) are mixed to form a dispersion of fine viscose particles. 3. The dispersion of fine viscose particles obtained in the preceding (2) is heated to aggregate the viscose in the dispersion, and neutralized with acid, to form fine cellulose particles. 4. The fine cellulose particles are separated from the mother liquid obtained in point 3 above and washed and dried, if necessary.

[0084] Viscose is a raw material for cellulose. It is preferable to use viscose with a gamma value of 30 to 100% by mass and an alkaline concentration of 4 to 10% by mass. Examples of the above-mentioned water-soluble anionic polymers include the sodium salt of polyacrylic acid, the sodium salt of polystyrene sulfonic acid, and the like. The above-mentioned calcium carbonate is used to prevent the aggregation of fine viscose particles in the dispersion and to reduce the size of the cellulose particles. An example of a calcium carbonate paste is Tama Pearl TP-221GS, marketed by Okutama Kogyo Co., Ltd. in Japan.

[0085] According to one embodiment, a cellulose derivative can be chosen from cellulose esters and ethers.

[0086] It is indicated that the term "cellulose ester" designates, in the above text, a polymer consisting of an a (1-4) sequence of partially or totally esterified anhydroglucose rings, the esterification being obtained by reaction of all or part of the free hydroxyl functions of said anhydroglucose rings with a linear or branched carboxylic acid or a carboxylic acid derivative (acid chloride or acid anhydride) containing 1 to 4 carbon atoms.

[0087] Preferably, the cellulosic ester results from the reaction of some of the free hydroxyl functions of said rings with a carboxylic acid containing 1 to 4 carbon atoms.

[0088] Advantageously, the cellulose esters are selected from cellulose acetates, propionates, butyrates, isobutyrates, acetobutyrates and acetopropionates and mixtures thereof.

[0089] These cellulosic esters can have an average molecular mass by weight ranging from 3,000 to 1,000,000, preferably from 10,000 to 500,000 and, even better, from 15,000 to 300,000.

[0090] In the present text, the term "cellulose ether" refers to a polymer consisting of an a (1-4) sequence of partially etherified anhydroglucose rings, some of the free hydroxyl functions of said rings being substituted by an -OR radical, R being preferably a linear or branched alkyl radical containing 1 to 4 carbon atoms.

[0091] Cellulose ethers are therefore preferably chosen from cellulose alkyl ethers with an alkyl group containing 1 to 4 carbon atoms, such as cellulose methyl, propyl, isopropyl, butyl and isobutyl ethers.

[0092] These cellulose ethers can have a weight average molecular mass ranging from 3,000 to 1,000,000, preferably from 10,000 to 500,000 and even better from 15,000 to 300,000.

[0093] As (a) particle, examples include the following spherical cellulose particles marketed by Daito Kasei in Japan: Cellulobeads USF.

[0094] The (a) particle may or may not be coated beforehand.

[0095] In a particular embodiment, the (a) particle is initially coated. The material of an initial coating of the particle is not limited, but an organic material such as a monocarboxylic or dicarboxylic acid or a salt thereof, an amino acid, an N-acylaminated acid, an amido, a silicone, and a modified silicone may be preferable. Examples of organic materials include potassium succinate, lauroyl lysine, and acrylic-modified silicone.

[0096] In other words, the (a) particle can be surface-treated. Examples of surface treatments include: 1. Silicone treatments such as treatments with methylhydrogen polysiloxanes, dimethyl polysiloxanes and tetramethyltetrahydrogencyclotetrasiloxane in the gas phase 2. Post-treatments such as alkyl chain addition and similar treatments following gas-phase silicone processing 3. Treatments of silane coupling agents 4. Treatments of titanium coupling agents 5. Treatments of aluminum coupling agents 6. Oil-based treatments 7. N-acylated lysine treatments 8. Polyacrylic acid treatments 9. Metallic soap treatments such as those with stearate salt or salt myristate 10. Acrylic resin-based treatments 11. Metal oxide treatments

[0097] It is possible to carry out a plurality of surface treatments in combination with the above treatments.

[0098] The quantity of (a) particle(s) in the composition according to the present invention may be 1% by weight or more, preferably 5% by weight or more and, even better, 10% by weight or more, relative to the total weight of the composition.

[0099] Furthermore, the quantity of (a) particle(s) in the composition according to the present invention may be less than or equal to 40% by weight, preferably less than or equal to 35% by weight and, even better, less than or equal to 30% by weight relative to the total weight of the composition.

[0100] The quantity of the (a) particle(s) in the composition according to the present invention can be from 1% to 40% by weight, preferably from 5% to 35% by weight and, even better, from 10% to 30% by weight, relative to the total weight of the composition.

[0101] (Charge)

[0102] The composition according to the present invention comprises (b) at least one filler other than (a) the particle. If two or more fillers are used, they may be identical or different.

[0103] The (b) charges may be in the form of a powder.

[0104] The term “charges” should be understood as meaning colorless or white solid particles of any shape, which are in a form which is insoluble and dispersed in the medium of the composition according to the present invention.

[0105] The (b) charge is different from the (a) particle.

[0106] The (b) charge can be inorganic or organic.

[0107] The (b) charge can be chosen from the group consisting of non-charges spherical, in particular lamellar charges, spherical charges (globular charges) and mixtures thereof. Non-spherical charges

Among the non-spherical mineral fillers that can be used in the composition according to the present invention, talc, kaolin, micas, aluminum magnesium silicate, bentone, calcium carbonate, magnesium hydrogen carbonate, hydroxyapatite, boron nitride, perlite, calcined talc, calcined micas, synthetic micas, lauroyl lysine, metallic soap, bismuth oxychloride, barium sulfate, magnesium carbonate and mixtures thereof may be mentioned.

[0109] It may be preferable that the (b) filler be chosen from micas, synthetic micas and mixtures thereof.

[0110] Mica is the name of a family of minerals, from the silicate group, phyllosilicate subgroup, formed mainly of potassium and aluminum silicate. It is characterized by its layered structure (phyllosilicates).

[0111] It is characterized by its layered structure (phyllosilicates), generally in flake form, its metallic luster, and its high heat resistance. The properties of micas—their transparency, heterogeneity, thermal properties, and good electrical insulation—are such that they are found in numerous applications.

[0112] The micas that can be used according to the present invention preferably have an average size less than or equal to 100 sqm, better still, from 1 to 60 sqm and even better still, from 1 to 20 sqm.

[0113] The term "average particle size" here refers to the median size of the volume D

[50] represents the maximum size of 50% of the particle volume. Sizes are measured by static light scattering using a commercial Malvem Master Sizer 3000 particle size analyzer, which allows the particle size distribution of all particles to be determined over a wide range, from 0.01 µm to 1000 µm. The data are processed using Mie's standard scattering theory. This theory is best suited to size distributions ranging from submicron to multimicron; it allows the determination of an "effective" particle diameter. This theory is notably described in the publication by Van de Hulst, H.C., "Light Scattering by Small Particles," Chapters 9 and 10, Wiley, New York, 1957. D

[50] represents the maximum size of 50% of the particle volume.

[0114] The micas that can be used according to the present invention are in a pure form. The micas can be selected from the group consisting of sericite, muscovite, fluorophlogopite, and mixtures thereof. Preferably, the following will be used:

[0115] - sericites such as the commercial product Sericite S-152-BC® (average size 6 qm) of the Miyoshi Kasei company;

[0119] It may be preferable for (b) charge to be chosen from the group consisting of muscovite, synthetic fluorophlogopite and a mixture thereof. Spherical charges

[0120] Among the spherical charges that can be used, spherical mineral charges and spherical organic charges may be mentioned. By "spherical charges" is to be understood charges or particles comprising at least one generally rounded portion, preferably defining at least a portion of a sphere, which may internally define a concavity or a depression.

[0121] Spherical mineral fillers:

[0122] Among the spherical mineral fillers that can be used, we can mention glass or ceramic microcapsules, titanium dioxide and silica and titanium dioxide composites, for example the TSG range marketed by Nippon Sheet Glas s.

[0123] Spherical organic charges:

[0124] Among the usable spherical organic fillers, we can mention lauroyl lysine, starch, carnauba microwaxes, such as the product marketed under the name Micro Care 350® by Micro Powders, synthetic microwaxes, such as the product marketed under the name Micro Ease 114S® by Micro Powders, microwaxes made from a mixture of carnauba wax and polyethylene wax, such as those marketed under the names Micro Care 300® and 310® by Micro Powders, and microwaxes made from a mixture of carnauba wax and synthetic wax, such as the product marketed under the name Micro Care 325® by Micro Powders Surface-treated fillers

[0125] The (b) charge may or may not have a surface treatment. In other words, the surface of the charge (b) may or may not be coated. Examples of surface treatments include:

[0126] (1) Treatments of fluorine-based compounds such as treatments with per- fluoroalkylphosphates, perfluoroalkylsilanes, perfluoropolyethers, fluorosilicones and fluorinated silicone resins

[0127] (2) Silicone treatments such as treatments with methylhydrogenpo- lysiloxanes, dimethylpolysiloxanes and tetramethyltetrahydrogencyclotetrasiloxane in the gas phase

[0128] (3) The pending treatments such as treatments to add an alkyl chain and similar after gaseous silicone treatment

[0129] (4) Treatments of silane coupling agents

[0130] (5) Treatments of titanium coupling agents

[0131] (6) Treatments of aluminum coupling agents

[0133] (8) N-acylated lysine treatments

[0134] (9) Polyacrylic acid treatments

[0135] (10) Metallic soap treatments such as those with stearate salt or with salt of myristate

[0136] (11) Acrylic resin-based treatments

[0137] (12) Metal oxide treatments

[0138] It is possible to carry out a plurality of surface treatments in combination with the above treatments.

[0139] It may be preferable for (b) the filler to be surface-treated with at least one silicone. The silicone may be chosen from polydialkylsiloxanes such as polydimethylsiloxane, polyalkylarylsiloxanes such as polymethylphenylsiloxane, polydarylsiloxanes such as polydiphenylsiloxanes, polyalkylhydrogensiloxanes such as methylhydrogenpolysiloxane, and modified polysiloxanes.

[0140] By way of example of the surface-treated filler, one may cite surface-treated micas such as surface-treated fluorophlogopite, preferably micas treated with silicone such as silicone-treated fluorophlogopite and, even better, methylhydrogenpolysiloxane-treated micas such as methylhydrogenpolysiloxane-treated fluorophlogopite.

[0141] It is preferable that the (b) filler be chosen from the group consisting of micas (untreated on surface), surface-treated micas and their mixtures.

[0142] It is preferable that the (b) filler be chosen from the group consisting of muscovite, synthetic fluorophlogopite, surface-treated synthetic fluorophlogopite and a mixture of these.

[0143] It is even more preferable that the (b) filler be chosen from the group consisting of muscovite, synthetic fluorophlogopite, synthetic fluorophlogopite treated with methylhydrogenpolysiloxane and a mixture of these.

[0155] The oil (c) can function as a binder for a powder such as the (a) particle(s) and the (b) filler(s) in the composition according to the present invention.

[0156] The oil (c) can also control the dispersion of a powder such as the (a) particle(s) and (b) filler(s) in the composition according to the present invention. The oil (c) can also improve the adhesion of a powder such as the (a) particle(s) and (b) filler(s) in the composition according to the present invention to the skin, and consequently, the oil (c) can provide a feeling of softness to the skin.

[0157] Here, "oil" means a fatty compound or oily substance that is in the form of a liquid or a paste (not a solid) at room temperature (25 °C) under atmospheric pressure (760 mmHg). Oils commonly used in cosmetics can be used alone or in combination. These oils can be volatile or non-volatile.

[0158] The oil may be a non-polar oil such as a hydrocarbon-based oil, a silicone oil or the like; a polar oil such as a vegetable or animal oil and an ester oil or an ether oil; or a mixture thereof.

[0169] As ester oils, C6-C30 and preferably C12-C22 fatty acid sugar esters and diesters may be used. It is recalled that the term "sugar" refers to oxygen-bearing hydrocarbon compounds containing several alcohol functional groups, with or without aldehyde or ketone functional groups, and comprising at least four carbon atoms. These sugars may be monosaccharides, oligosaccharides, or polysaccharides.

[0170] Examples of suitable sugars that may be mentioned include sucrose, glucose, galactose, ribose, fucose, maltose, fructose, mannose, arabinose, xylose and lactose and derivatives thereof, including alkyl derivatives, such as methyl derivatives, for example methylglucose.

[0171] Sugar esters of fatty acids may be selected in particular from the group comprising the esters or mixtures of esters of sugars described above and of linear or branched fatty acids, saturated or unsaturated in C6-C30, and preferably in Ci2-C22. If unsaturated, these compounds may have one to three conjugated or non-conjugated carbon-carbon double bonds.

[0180] These silicone oils can also be organo-modified. The organo-modified silicones that can be used according to the present invention are silicone oils as defined above, and comprise in their structure one or more organofunctional groups attached via a hydrocarbon-based group.

[0181] Organopolysiloxanes are defined in more detail in Chemistry and Technology of Silicones (1968) by Walter Noll, Academy Press. They can be volatile or non-volatile.

[0182] When volatile, silicones are particularly chosen from those having a boiling point between 60 °C and 260 °C, and even more particularly from:

An example is deca-methyltetrasiloxane, marketed in particular under the name SH 200 by Toray Silicone. Silicones belonging to this category are also described in the article published in Cosmetics and Toiletries, Vol. 91, Jan. 76, pp. 27–32, Todd & Byers, Volatile Silicone Fluids for Cosmetics. The viscosity of silicones is measured at 25 °C according to ASTM 445 Annex C.

[0186] Non-volatile polydialkylsiloxanes can also be used. These non-volatile silicones are more particularly chosen from among the polydialkylsiloxanes, among which the main examples are polydimethylsiloxanes containing trimethylsilyl terminal groups.
