The present invention provides a modified powder that is obtainable by coating the surface of a base powder with a hydrophobizing agent and a cationic surfactant. In the modified powder described above, it is preferable that the amount of coated hydrophobizing agent and the amount of coated cationic surfactant are 3 to 90% by mass and 0.5 to 10% by mass, respectively, relative to the self weight of the base powder. In the modified powder described above, it is preferable that the mass ratio of the coated hydrophobizing agent and the coated cationic surfactant is from 1:1 to 9:1. In addition, the present invention provides a cosmetic composition comprising the above modified powder wherein the modified powder and the base powder have an ultraviolet scattering effect. In the cosmetic composition described above, it is preferable that the blended amount of the modified powder is from 0.5 to 100% by mass. Furthermore, the present invention provides a sunscreen cosmetic composition comprising the above modified powder with an ultraviolet scattering effect. In the sunscreen cosmetic composition described above, it is preferable that the base powder is one or more selected from the group consisting of titanium oxide, zinc oxide, iron oxide, cerium oxide, bismuth oxide, zirconium oxide, chromium oxide, and tungstic acid. In the sunscreen cosmetic composition described above, it is preferable that the blended amount of the modified powder is from 1 to 40% by mass.

The present invention provides an external composition for skin that has excellent effects in improving elasticity and alleviating wrinkles while moisturizing the skin, has good spreadability on the skin, and has no stickiness. The external composition for skin of the present invention is characterized by comprising: (A) an acrylic polymer comprising the following monomers (a1), (a2), and (a3) as constituent monomers: (a1) acrylic acid or methacrylic acid; (a2) an alkyl acrylate or alkyl methacrylate; and (a3) an ester between acrylic acid or methacrylic acid and polyoxyethylene alkyl ether; and (B) a cross-linked polyamino acid or its salt. In the external composition for skin of the present invention, it is preferable that (A) is 0.01 to 10.0 weight % as a polymer, and (B) is 0.0001 to 5.0 weight % as a polymer.
摘要:
This object of the invention is to provide an oil-in water emulsion cosmetic composition having fine sense of use and excellent dispersion stability, and does not occur twisting upon drying.In advance, a hydrophobicized powder is dispersed in an oil phase and processed with wet type disperser such as beads mill, dispersing solution is obtained. And then said dispersing solution and a water phase are processed with homomixer, an oil-in water emulsion composition having excellent sense of use and dispersibility of powder after applying to skin can be obtained. The dispersing stability of powder is extremely good by using a particular dispersant and a particular oil component. The dispersion stability of powder is further improved, and the precipitation and creaming of the emulsion particle can be solved by blending thickener having salt tolerance.Sticky feeling is solved by using succinoglycan as a thickener, and twisting is solved by plasticizing said succinoglycan.
