Title:
OIL-BASED COSMETIC
Document Type and Number:
WIPO Patent Application WO/2021/201031
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an oil-based cosmetic which has long-lasting makeup wear resistance without causing tightness or dryness and exhibits a good effect of being free of secondary adhesion to clothes or dishes. The oil-based cosmetic comprises: (A) a silicone resin having a weight average molecular weight of 1500-40000 and having structural units of (A-1) (R1
3SiO1/2)a, (A-2) (R2
2SiO2/2)b, (A-3) (R3SiO3/2)c, and (A-4) (SiO4/2)d (in the formulae, R1, R2, and R3 are each independently a group selected from among a C1-8 alkyl group, a C6-12 aryl group, and a C1-8 fluorene-substituted alkyl group, a has a value of 0.2-0.5, b has a value of 0.0-0.1, c has a value of 0.2-0.6, d has a value of 0.2-0.5, the value of a+b+c+d is 1.0, the value of a/(c+d) is 0.3-0.9, and the value of c/d is 0.4-3.0); (B) a volatile oil; (C) one or more selected from among hydrocarbon oils and ester oils having a weight average molecular weight of 700-5000; and (D) one or more selected from among oil-based gelling agents and waxes.
