Abstract: To provide surface-treating agents that can provide excellent hydrophobicity to powder and can improve its rinsability, to provide surface-treated powders that are treated with the surface-treating agent, and to provide cosmetics that comprise the surface-treated powder. A surface-treating agent consisting of a polymer which comprises a monomer (A) represented by the general formula (1) described below as a constituent monomer. (wherein R1 represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms, R2 represents an alkylene group having 4 to 22 carbon atoms, X1 represents an —NH— group or an oxygen atom, and M1 represents a hydrogen atom or a monovalent inorganic or organic cation.

Abstract: 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.
