Estimating the term…
Provided is a silicone resin-coated silicone elastomer particle that is superior in dispersibility into organic resins, in stress relaxation performance, and the like, and that has low dust scattering when mixing and thus is superior in ease of handling. Also provided is an organic resin additive, an organic resin, a coating composition, or a coating agent composition, and applications such as in cosmetic compositions, including the particle. The silicone resin-coated silicone elastomer particle has a structure wherein at least two silicon atoms in a silicone elastomer particle are cross-linked through a silalkylene group with a carbon number between 4 and 20 where some or all of the surface thereof is coated with a silicone resin structured from siloxane units expressed by SiO4/2.
A silicone resin-coated silicone elastomer particle having a structure wherein at least two silicon atoms in a silicone elastomer particle are cross-linked through a silalkylene group with a carbon number between 4 and 20 and where at least some or all of the surface thereof is coated with a silicone resin comprising siloxane units expressed by SiO4/2 and wherein the inclusion proportion of silicon atom-bound hydrogen is no greater than 300 ppm, per unit mass.
