Description

[Technical field]

[0001] The present invention relates to a powdery composition suitable for the cosmetic treatment of keratinous materials such as the skin. [Background technology]

[0002] Skin make-up cosmetics can generally be used not only to impart an attractive color to the skin, such as the face, but also to cover skin imperfections, such as redness, bruises, and wrinkles.

[0003] Certain makeup cosmetic preparations may be in the form of a powdery cosmetic composition, which generally comprises a high content of powder, for example at least about 70% by weight of powder based on the total weight of the composition. [Prior art documents] [Non-patent literature]

[0005] Some conventional powdery cosmetic compositions do not provide sufficient long-lasting cosmetic effects on skin.For example, when such conventional powdery cosmetic compositions are used for a long period of time, it may be difficult for the conventional powdery cosmetic compositions to keep the skin matte for a long time and / or keep the skin color unchanged due to the oil-containing sebum secreted on the skin over time.In terms of good usability, a long-lasting cosmetic effect is desirable for the powdery cosmetic composition.Therefore, good sebum absorption is required for the long-lasting cosmetic effect of the powdery cosmetic composition.

[0006] In addition, good texture is also required for powdery cosmetic compositions.

[0007] However, it is difficult for some conventional powdery cosmetic compositions to achieve both good sebum absorption and good texture. Generally, powdery cosmetic compositions with good sebum absorption tend to have poor texture, while powdery cosmetic compositions with good texture tend to have poor sebum absorption.

[0008] Therefore, an object of the present invention is to provide a powdery composition that can have both good sebum absorption and good texture. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] As a result of extensive investigations, the present inventors have discovered that it is possible to provide a powdery composition that can have both good sebum absorbency and good texture.

[0025] The composition according to the present invention is a composition, preferably a cosmetic composition, more preferably a cosmetic composition for making up keratinous materials such as the skin, comprising (a) at least one particle having an oil wetting point of at least 150 ml / 100 g, preferably at least 180 ml / 100 g; (b) at least one filler other than the (a) particles; Including, The total amount of (a) particles and (b) filler is greater than 80% by weight, preferably greater than 85% by weight, and more preferably greater than 90% by weight, based on the total weight of the composition; It is a composition.

[0026] Since the total amount of the (a) particles and (b) filler is more than 80% by weight, based on the total weight of the composition according to the present invention, the composition according to the present invention can be considered to be a powdery composition.

[0027] The composition according to the present invention can provide both good oil / sebum absorption and good texture.Therefore, the composition according to the present invention can provide both long-lasting beauty effects on the sebum secreted on the skin over time and comfortable use.Therefore, the composition according to the present invention can exhibit good usability.

[0028] When (a) particles have a water wetting point of at least 200ml / 100g, preferably at least 250ml / 100g, more preferably at least 300ml / 100g, the composition according to the present invention can also have good water absorption, and therefore it can also provide good water resistance.Therefore, in this case, the composition according to the present invention can also provide long-lasting cosmetic effect against rain or sweat.

[0029] When the amount of silica powder, in particular porous silica powder, in the composition according to the 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.

[0030] When the amount of resin or plastic powders, in particular polyamide powders and poly(meth)acrylate powders, such as Nylon® powder and 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 pollution by resin or plastic powders can be reduced or avoided.

[0031] Each of the inventions will be described in detail hereinafter.

[0032] [Composition] The composition according to the invention comprises (a) at least one particle having an oil wetting point of at least 150 ml / 100 g, preferably at least 180 ml / 100 g; (b) at least one filler other than the (a) particles; Including, The total amount of the (a) particles and the (b) filler is greater than 80% by weight, preferably greater than 85% by weight, and more preferably greater than 90% by weight, based on the total weight of the composition.

[0033] (particle) The composition according to the invention comprises (a) at least one type of particle having unique properties. When two or more types of such particles are used, they may be the same or different.

[0034] The (a) particles can be in the form of a powder.

[0035] (a) the particles have a wetting point for oil that is at least 150 ml / 100 g, preferably at least 180 ml / 100 g, and / or preferably no greater than 1500 ml / 100 g.

[0036] The term "wetting point for oil" as used herein means the quantity or amount of oil required to completely wet a powder of interest, which may be realized in particular by forming a paste with the powder of interest.

[0037] The oil wetting point can be determined according to ISO-787 / 5-1980, which corresponds to JIS K 5101-13-1, provided that isononyl isononanoate is used instead of linseed oil.

[0038] In particular, the wetting point for oil can be determined by the following protocol. (1) 2 g of the target powder is kneaded on a glass plate using a spatula while adding an oil, specifically a linear ester oil, such as isononyl isononanoate (WICKENOL 151 / ALZO). (2) Once the desired powder is completely wetted and begins to form a paste, the mass of oil added is determined as the mass at the wetting point. (3) The wetting point for oil is calculated from the equation: Wetting point for oil (ml / 100 g) = {(mass of wetting point) / 2 g} x 100 / density of oil.

[0039] Since the (a) particles have a wetting point for oil that is at least 150 ml / 100 g, the composition according to the present invention comprising the (a) particles can have good oil / sebum absorption capacity. Therefore, the composition according to the present invention can provide long-lasting cosmetic effects against sebum secreted over time on the skin.

[0040] Sebum contains oil, so the higher the wetting point for oil, the better the sebum absorption.

[0041] It is preferred that the (a) particles also have a wetting point for water of at least 200 ml / 100 g, preferably at least 250 ml / 100 g, more preferably at least 300 ml / 100 g, even more preferably at least 350 ml / 100 g, and / or preferably no greater than 1500 ml / 100 g.

[0042] Similarly, the term "water wetting point" as used herein means the amount or quantity of water required to completely wet a powder of interest, which may be realized, inter alia, by the formation of a paste with the powder of interest.

[0043] The oil wetting point can also be determined according to ISO-787 / 5-1980, which corresponds to JIS K 5101-13-1, provided that water is used instead of linseed oil.

[0044] In particular, the water wetting point can be determined by the following protocol. (1) 2 g of the desired powder is kneaded with a spatula on a glass plate while adding water having a density of 0.998 g / ml. (2) When the desired powder is completely wetted and begins to form a paste, the mass of water added is determined as the mass at the wetting point. (3) The wetting point for water is calculated from the equation: wetting point for water (ml / 100 g) = {(mass at wetting point) / 2 g} x 100 / density of water.

[0045] When the (a) particles have a water wetting point of at least 200 ml / 100 g, the composition according to the present invention comprising the (a) particles can have good water absorption. Thus, the composition according to the present invention can provide long-lasting cosmetic effects against water, such as in rain or sweat.

[0046] The higher the water wetting point, the better the resistance to rain or sweat.

[0047] (a) It is preferred that the water wetting point / oil wetting point ratio of the particles is 5 or less, preferably 4 or less, more preferably 3 or less, even more preferably 2 or less, and is preferably 0.1 or more.

[0048] The particle size of the (a) particles is not limited, but the number average particle size of the (a) particles is preferably 50 μm or less, more preferably 30 μm or less, more preferably 10 μm or less, and even more preferably 2 to 5 μm.

[0049] (a) The particle size of the particles corresponds to the primary particle size. Additionally, particle size in this specification means the average, i.e., mean particle size, which may be the volume-average particle size that can be determined, for example, by a laser diffraction particle size analyzer.

[0050] It is preferred that 90% by volume or more of the (a) particles have an average (primary) particle size in the range of 0.1 to 10 μm, preferably 0.5 to 8 μm, more preferably 1 to 7 μm. When 90% by volume or more of the (a) particles have an average (primary) particle size in the range of 1 to 7 μm, optical effects attributable to the particles can also be achieved.

[0051] The (a) particles preferably have a ratio of the longest diameter to the shortest diameter within a range of 1.0 to 10, preferably 1.0 to 5, and more preferably 1.0 to 3. It is more preferable that the (a) particles are spherical and have a ratio of the longest diameter to the shortest diameter of 1.0 to 1.1.

[0052] The (a) particles may be porous or non-porous, however, it is preferred that the (a) particles are porous.

[0053] (a) The porosity of the particles is 0.05 m according to the BET method. 2 / g~1,500m 2 / g, more preferably 0.1m 2 / g~1,000m 2 / g, more preferably 0.2m 2 / g~500m 2 The specific surface area may be characterized in terms of specific surface area in g / g.

[0054] The (a) particles can include any organic or inorganic material that can be selected from, but is not limited to, polysaccharides, such as cellulose; boron compounds, such as boron nitride; metal compounds, such as alumina, barium sulfate, and magnesium carbonate; perlite; and mixtures thereof.

[0055] It is preferred that the (a) particles comprise at least one polysaccharide.

[0056] The polysaccharide may be selected from alginic acid, guar gum, xanthan gum, gum arabic, arabinogalactan, carrageenan, agar, karaya gum, tragacanth gum, tara gum, pectin, locust bean gum, curdlan, gellan gum, dextran, pullulan, hyaluronic acid, cellulose and its derivatives, and mixtures thereof. Cellulose and its derivatives are preferred. Cellulose is more preferred.

[0057] The (a) particles preferably contain cellulose. It is more preferable that the (a) particles consist of cellulose. In other words, it is more preferable that the (a) particles are cellulose particles. Therefore, the (a) particles do not have to be composite particles containing cellulose and any other material.

[0058] In the present invention, the cellulose that can be used is not limited by the type of cellulose, such as cellulose I, cellulose II, etc. As the cellulose that can be used as the material of the (a) particles for the present invention, type II cellulose is preferred.

[0059] (a) The cellulose that may be used as material for the particles may be in any particulate form, in particular in the form of spherical particles.

[0060] The cellulose particles, preferably spherical cellulose particles, can be prepared, for example, as follows. (1) A slurry of calcium carbonate as a coagulation inhibitor is added to an alkaline aqueous solution of a water-soluble anionic polymer and stirred. (2) Viscose is mixed with the aqueous solution obtained in (1) above to form a dispersion of viscose microparticles. (3) The dispersion of viscose microparticles obtained in (2) above is heated to aggregate the viscose in the dispersion, and neutralized with an acid to form cellulose microparticles. (4) The cellulose microparticles are separated from the mother liquor obtained in (3) above, and are washed and dried as necessary.

[0061] Viscose is a raw material for cellulose. It is preferable to use viscose having a gamma value of 30-100% by weight and an alkali concentration of 4-10% by weight. Examples of the water-soluble anionic polymer include sodium polyacrylate and sodium polystyrene sulfonate. The calcium carbonate is used to prevent the aggregation of viscose particles in the dispersion and to reduce the particle size of the cellulose particles. Examples of the calcium carbonate slurry include Tama Pearl TP-221GS, which is sold by Okutama Kogyo Co., Ltd., Japan.

[0062] According to one embodiment, the cellulose derivative may be chosen from cellulose esters and ethers.

[0063] It is pointed out that the term "cellulose ester" in the present context means a polymer consisting of an α(1-4) sequence of partially or completely esterified anhydroglucose rings, the esterification being obtained by reaction of all or only a portion of the free hydroxyl functions of said anhydroglucose rings with linear or branched carboxylic acids or carboxylic acid derivatives (acid chlorides or acid anhydrides) containing 1 to 4 carbon atoms.

[0064] Preferably, the cellulose esters are obtained by reaction of some of the free hydroxyl functions of said ring with a carboxylic acid containing from 1 to 4 carbon atoms.

[0065] Advantageously, the cellulose ester is chosen from cellulose acetate, cellulose propionate, cellulose butyrate, cellulose isobutyrate, cellulose acetobutyrate and cellulose acetopropionate, and mixtures thereof.

[0066] These cellulose esters may have a mass average molecular weight within the range of 3,000 to 1,000,000, preferably 10,000 to 500,000, and more preferably 15,000 to 300,000.

[0067] In the present context, the term "cellulose ether" refers to a polymer consisting of an α(1-4) sequence of partially etherified anhydroglucose rings, in which some of the free hydroxyl functions are replaced by -OR groups, where R is preferably a linear or branched alkyl group containing from 1 to 4 carbon atoms.

[0068] Therefore, the cellulose ether is preferably selected from cellulose alkyl ethers having an alkyl group containing from 1 to 4 carbon atoms, such as cellulose methyl, propyl, isopropyl, butyl and isobutyl ethers.

[0069] These cellulose ethers may have a mass average molecular weight within the range of 3,000 to 1,000,000, preferably 10,000 to 500,000, and more preferably 15,000 to 300,000.

[0070] (a) As particles, mention may be made, for example, of spherical cellulose particles, Cellulobeads USF, marketed by Daito Kasei Kogyo Co., Ltd., Japan.

[0071] (a) The particles may be pre-coated or uncoated.

[0072] In a particular embodiment, (a) particle is originally coated.The material of the original coating of particle is not limited, but organic material, such as mono- or dicarboxylic acid or its salt, amino acid, N-acyl amino acid, amide, silicone and modified silicone may be preferred.The organic material may include potassium succinate, lauroyl lysine and acrylic modified silicone.

[0073] In other words, the (a) particles may be surface-treated. Examples of surface treatments that may be mentioned are: (1) Silicone treatment, for example, treatment with methylhydrogenpolysiloxane, dimethylpolysiloxane, and tetramethyltetrahydrogencyclotetrasiloxane in the gas phase. (2) Pendant treatment, for example, a treatment in which alkyl chains or the like are added after a vapor-phase silicone treatment (3) Silane coupling agent treatment (4) Titanium coupling agent treatment (5) Aluminum coupling agent treatment (6) Oil treatment (7) N-acylated lysine treatment (8) Polyacrylic acid treatment (9) Metal soap treatment, e.g., with stearates or myristates (10) Acrylic resin treatment (11) Metal oxide treatment.

[0074] In combination with the above treatments, multiple surface treatments can be carried out.

[0075] The amount of (a) particles in the composition according to the present invention may be 1% by weight or more, preferably 5% by weight or more, more preferably 10% by weight or more, based on the total weight of the composition.

[0089] The term "average particle size" refers here to the median volume size D

[50] , which represents the maximum size of 50% by volume of the particles. This size is measured by static light scattering using a commercially available Malvern Master Sizer 3000 particle size analyzer, which allows the determination of the overall particle size distribution in a wide range of particles 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 suitable for size distributions in the submicron to micromicron range, which allows the "effective" particle diameter to be determined. This theory is described in detail in the publication "Light Scattering by Small Particles" by Van de Hulst, HC, chapters 9 and 10, Wiley, New York, 1957. D

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