Abstract:
Silicone particles having excellent dispersibility are provided via the method herein. A cosmetic material having excellent feeling of use, and a highly functional paint and an electronic material are also provided. The silicone particles include a siloxane as a component. A content of a hydrogen atom bonded to a silicon atom per unit mass is 300 ppm or less, or optionally is 20 ppm or less. In addition, the silicon atom in the siloxane as a component for the silicone particles is crosslinked with another silicon atom via an alkylene group having a carbon number of 4 to 20.
