Document Type and Number:
WIPO Patent Application WO/2024/038717
Kind Code:
A1
Abstract:
The present invention provides a crosslinked organic silicon resin which is an addition reaction product of the component (A) and the component (B) described below, wherein the amount of a hydrogen gas generated from this crosslinked organic silicon resin per mass thereof is 1.5 mL/g or less in a standard state. This crosslinked organic silicon resin has excellent long-term stability and forms a coating film that exhibits excellent oil resistance and high bendability, while being free from stickiness and brittleness.
Component (A): an alkenyl group-containing organic silicon resin that has one or more alkenyl groups in each molecule
Component (B): an organohydrogen polysiloxane that has two or more hydrosilyl groups in each molecule
The present invention also provides a cosmetic preparation which comprises this crosslinked organic silicon resin and has good feeling of use and good spreadability, while having excellent secondary adhesion prevention properties.
