Organopolysiloxane having amide group, and cosmetic material containing same

摘要

Provided are an organopolysiloxane that exhibits good dispersion stability within not only organic oil agents but also cosmetic materials that contain a powder, and is able to produce a cosmetic material that exhibits excellent skin affinity, an organopolysiloxane that does not impart a sticky feeling, and exhibits excellent skin affinity and skin adhesion, and a cosmetic material including such an organopolysiloxane. The organopolysiloxane is represented by formula (1) below:
in which R 1 represents a hydrocarbon group such as an alkyl group, R 2 represents a group represented by formula (3) or formula (4) below:
in which either R 4 represents a specific hydrocarbon group and R 5 represents a hydrogen atom or a specific hydrocarbon group, or alternatively, at least one of R 4 and R 5 represents a hydroxyalkyl group, and
A represents a group containing an organosilyl group or organosiloxane residue.
