US 2014/0193353 A1 · Novel Organopolysiloxane Elastomer And Use Therefor

Abstract

The present invention relates to an organopolysiloxane elastomer having a silicon-bonded sugar alcohol-modified group and having a crosslinked three-dimensional network structure comprising a carbon-silicon bond in the crosslinking portion. The organomodified organopolysiloxane elastomer of the present invention has, for example, affinity with various oil agents, has excellent viscosity-improving characteristics, gelification characteristics, and emulsification characteristics, imparts excellent tactile sensation—in particular, an excellent tactile sensation characterized by smoothness with a velvet-like thickness—and imparts an excellent sensation during use.
