Surface-treating agents, surface-treated powders, and cosmetics comprising the same |
摘要 |
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.) |

1. A surface-treated powder comprising:
powder particles having a surface; and a polymer including at least 70 mole % of 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, wherein the polymer is coated on the surface of the powder particles.
