Abstract:
A trisiloxane having at least one carbinol functional group comprises the reaction product of (A) an initial trisiloxane and (B) an organic compound. Component (A) has a pendant silicon-bonded functional group selected from a hydrogen atom, an epoxy-containing group, an ethylenically unsaturated group, and an amine group. Typically, component (A) is free of certain terminal silicon-bonded functional groups and is free of polyoxyalkylene groups. Component (B) has a functional group reactive with the pendant silicon-bonded functional group of component (A), and has at least one hydroxyl functional group. The trisiloxane is useful for a number of applications including use as a detergent additive. The trisiloxane may be of the following general formula (I): (R13SiO1/2)(R1R3SiO2/2)(R13SiO1/2) (I). In formula (I), each R1 is an independently selected hydrocarbyl group. R3 may be selected from the groups (i) to (iv) described herein. Typically, the trisiloxane has 1-6 carbinol groups.

R 3 may be selected from the groups (i) to (x) described herein, each of the groups having at least one carbinol group. Typically, the trisiloxane has 1-6 carbinol groups.
Abstract:
A cosmetic composition comprises (A) a silicone elastomer. The (A) silicone elastomer comprises the reaction product of: (a) a branched organosiloxane; (b) a crosslinking agent; and (c) a hydrosilylation catalyst. The cosmetic composition further comprises (B) a carrier fluid. A method of preparing the cosmetic composition is also disclosed.
