Title:
COSMETIC COMPOSITION OR EXTERNAL COMPOSITION, AND COSMETIC RAW MATERIAL COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2018/066559
Kind Code:
A1
Abstract:
The present invention provides a cosmetic composition or an external composition containing a resin-linear organopolysiloxane block copolymer, the composition having a high degree of freedom of formulation design for the sake of exceptional compatibility with other cosmetic raw materials, exceptional film-forming properties and film traceability, and suppressed stickiness, etc., of the film. The resin-linear organopolysiloxane block copolymer contains a resin-linear organopolysiloxane block copolymer (A) having a structure in which a resin structure (A1) block that has siloxane units represented by R1SiO3/2 (R1 is a monovalent organic group, a hydroxyl group, or a C1-6 alkoxy group) or SiO4/2 and a linear structure (A2) block represented by (R2SiO2/2)n (n is an integer of 5 or higher, and R is an alkyl group, a fluoroalkyl group, or an aryl group) are connected by an Si-O-Si bond in the molecule, as well as having R1SiO3/2 units in the molecule.
