ALKOXYLATED FLUORINE-MODIFIED SILOXANE POLYMER, SURFACE TREATED POWDER AND COSMETICS COMPRISING THE SAME

摘要

An alkoxylated fluorine-modified siloxane polymer consisting of (1) R1 3SiO1/2 unit (2) SiO2, (R2-O-)SiO3/2, (R2-O-)2SiO and/or (R2-O-)3SiO1/2 unit, and (3) (Rf-X-)(R2-O-)2SiO1/2, (Rf-X-)(R2-O-)SiO and/or (Rf-X-)SiO3/2 unit where R1 each is an unsubstituted or substituted monovalent organic group, Rf is a fluoroalkyl group having 1 to 6 carbon atoms wherein at least one fluorine atom is optionally substituted by hydrogen or halogen atom(s), X is a bivalent organic group, R2 each is a hydrogen atom or an unsubstituted or substituted monovalent organic group, and the alkoxylated fluorine-modified siloxane polymer has at least one R2-O- group.
