BEST MODE FOR CARRYING OUT THE INVENTION (1) Powder Granulation Composition of the Present Invention The powder granulation composition of the present invention is characterized by containing a surface-treated powder. As the powder to be the base of the surface-treated powder, any powder used in cosmetics can be used without particular limitation, and examples thereof include titanium dioxide, zinc oxide, iron oxide, ultramarine blue, navy blue, and talc. , Kaolin, mica, sericite, calcium silicate, magnesium silicate,
Preferable examples thereof include anhydrous silicic acid, alumina, and composites thereof such as titanium mica and iron-doped titanium dioxide.
As for the surface treatment, the surface treatment method usually used in cosmetics can be preferably exemplified as in the case of the powder type. For example, dimethicone, hydrogenmethylpolysiloxane, perfluoroalkyldimethylmethoxysilane and other silane coupling agents. Baking treatment of silicones such as, coating treatment with perfluoroalkyl phosphate diethanolamine salt, coating treatment with fatty acid metal soap such as zinc stearate, coating treatment with acylated amino acid derivative such as aluminum acylglutamate, lecithin or its metal salt A preferable example is a coating treatment such as. Such surface treatment is performed by coating 1 to 20% by weight of the powder with a treating agent, if necessary using a solvent, and then applying 1 to 7 at room temperature or 200 to 500 ° C. under heating conditions.
It is performed by treating for 2 hours and fixing the surface treatment agent on the powder. At this time, it may be performed in a non-oxidizing atmosphere such as under a nitrogen stream. The powder-granulated composition of the present invention may contain only one kind of such surface-treated powder, or may contain two or more kinds in combination.
In the granulation composition of the present invention, the preferable content of the surface-treated powder is 2 to 9 with respect to the total amount of the powder granulation composition.
It is 5% by weight, and more preferably 5 to 95% by weight. One or more selected from such surface-treated powders and optionally titanium dioxide, zinc oxide, iron oxide, ultramarine blue, dark blue, talc, kaolin, mica, sericite, calcium silicate, magnesium silicate, anhydrous One or two selected from powders that are not surface-treated such as silicic acid, alumina, titanium mica, and iron-doped titanium dioxide.
The powder granulated product of the present invention can be obtained by granulating the seeds or more. At this time, it is preferable that the surface-treated powder or the non-treated powder contains a powder having a pearl luster. Examples of the powder having such a pearly luster include titanium mica which may be surface-treated, titanium sericite which may be surface-treated, bismuth oxychloride which may be surface-treated, and guanine which may be surface-treated ( Preferred examples include fish scale foil). Of course, these may be colored with an organic dye or the like. Since the powder having such a pearly luster can change the texture of color when used, it is possible to further provide a feeling of makeup. The content of the pearly luster powder in the granulation composition of the present invention is preferably 2 to 90% by weight, more preferably 3% by weight.
Is about 70% by weight. The powder granulation composition of the present invention can be granulated by treating the above powder components according to a conventional method. As such a granulation method, water, polyhydric alcohol, oil or wax is added as a granulation medium,
Using a Henschel mixer or a Glad granulator, a fluidized bed granulation method of rotating and mixing to granulate, using a Numalmelizer or a flow coater, etc., while rolling powders under blast, sticking media such as oil and wax Preferred examples include a tumbling layer granulation method of spraying and granulating, a kneading with a volatile liquid, and an extrusion granulation method of extruding a clay-like product and extruding it from a mesh with a granulator for granulation. . When extrusion granulation or the like is performed, it is preferable to adjust the granulated product into a shape close to a sphere using a device such as a Marumerizer. After granulation, the volatile components can be removed by drying. Of these, the fluidized bed granulation method is particularly preferable. By performing a treatment such as sieving or sizing after granulation, the particle diameters can be made uniform. In such granulation, it is preferable to allow a water-soluble polymer to coexist in addition to the surface-treated powder. This is because the water-soluble polymer serves as a binder and exerts an action of physically maintaining the granules after it is contained in the cosmetic. As the water-soluble polymer, gum arabic, xanthan gum, those classified as natural thickening polysaccharides such as quinseed gum and hydroxypropylmethyl cellulose, chemically modified water-soluble cellulose derivatives such as methyl cellulose and the like can be preferably exemplified. Of these, one or more selected from xanthan gum and water-soluble cellulose derivatives can be exemplified more preferably. The preferable content of these water-soluble polymers is 0.05 to 10
%, More preferably 0.1 to 5% by weight. The powder granulation composition thus obtained is a cosmetic base,
In particular, it is very useful as a raw material for cosmetics because it has a very stable property in a cosmetic base containing an aqueous component, particularly, a property that it is hard to disintegrate due to vibration. In addition, even when used by being dispersed in a water-based cosmetic, it has a secondary effect that the makeup is not easily destroyed by sweat or the like. In the cosmetic of the present invention, the content of the granulation composition of the present invention is preferably 1 to 40% by weight, more preferably 5 to 30% by weight, based on the total amount of the cosmetic.

(2) Cosmetic of the present invention The cosmetic of the present invention is characterized by containing the above-mentioned powder granulation composition of the present invention. The cosmetic of the present invention can be used without particular limitation as long as it is a commonly used dosage form and has a powder-containing dosage form. For example, powder cosmetics and oil gel cosmetics can be used. , Aqueous dispersion cosmetics,
Examples thereof include cosmetics dispersed in emulsion. Among these, a particularly preferred dosage form is a dosage form containing an aqueous component, and particularly a dosage form in which the powder granulation composition of the present invention is dispersed in an aqueous medium. In addition to the powder granulation composition of the present invention, such cosmetics may contain optional components usually used in cosmetics. Such optional components include, for example, hydrocarbons such as petrolatum and microcrystalline wax, esters such as jojoba oil and cetyl isooctanate, triglycerides such as olive oil, higher alcohols such as octadecyl alcohol and oleyl alcohol, Polyhydric alcohols such as glycerin, 1,3-butanediol, 1,2-pentanediol, isoprene glycol and dipropylene glycol, nonionic surfactants, anionic surfactants, cationic surfactants, amphoteric surfactants, Examples thereof include thickeners such as ethanol and carbopol, antiseptics, ultraviolet absorbers and antioxidants. In addition, the cosmetic of the present invention has the property of imparting an excellent moist feeling to the treated powder, which is an essential component of the powder granulation composition, which is a constituent factor of the cosmetic, and therefore has an animal property such as placenta extract and collagen. , Especially, originating from an animal of Artiodactyla, which exhibits excellent moisturizing properties without containing a hydrophilic moisturizing component, the preferred form of the cosmetic composition of the present invention is:
A form not containing such components can be exemplified. In the cosmetics of the present invention, in the usual contained form, the powder is agglomerated, carboxyvinyl polymer or acrylic acid
Even if a thickening agent such as an alkyl methacrylate (C10-30) copolymer is used, it does not affect the dispersibility of the powder granulation composition. Therefore, such a component is used to prepare a viscosity stable formulation. It is also possible to particularly preferably exemplify an aqueous dispersion type cosmetic having such a constitution. In the cosmetic of the present invention, the preferable content of carboxyvinyl polymer or acrylic acid / methacrylic acid (C10-30) alkyl copolymer is 0.01 to 5% by weight, and more preferably 0.05 to 2% by weight. %.
