Document Type and Number:
WIPO Patent Application WO/2023/286473
Kind Code:
A1
Abstract:
The present invention relates to a paste-like silicone composition containing: (A) a crosslinked organopolysiloxane comprising a hydrosilylation reaction product of (A-1) an organohydrogenpolysiloxane having, in one molecule, two or more hydrogen atoms bonded to a silicon atom and (A-2) an alkenyl group-containing organopolysiloxane having, in one molecule, two or more alkenyl groups bonded to a silicon atom; and (B) an oiling agent which is liquid at 25°C, the paste-like silicone composition being characterized in that the amount of each of octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecamethylcyclohexasiloxane contained in the composition is less than 2,000 ppm. Accordingly, provided is a stable paste-like silicone composition having little temporal change such as plasticization return and having less odor.
