Title:
CO-MODIFIED ORGANOPOLYSILOXANE AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/065520
Kind Code:
A1
Abstract:
[Problem] To provide a co-modified organopolysiloxane which has high affinity and compatibility with a wide range of cosmetic materials (in particular, non-silicone-based oils such as fatty acid ester oils), and, when used together with a powder, which can form a good and stable slurry without causing thickening or dispersion failure, and use of the co-modified organopolysiloxane. [Solution] A co-modified organopolysiloxane which is represented by structural formula (1) and has an HLB value of 0.5-2.0 and a viscosity of 200-1500 mPa·s, and use of the co-modified organopolysiloxane as a powder dispersant, etc.　(In the formula: R1 represents a monovalent hydrocarbon group having 1-30 carbon atoms or a hydrogen atom; R2 represents a monovalent hydrocarbon group having 6-30 carbon atoms; L1 represents an organosilicon-containing organic group selected from a silylalkyl group having a carbosiloxy dendron structure and a group having a siloxane macromer structure; and Q represents a hydrophilic group which is a (poly)glycerol residue or a sugar alcohol residue).
