Abstract

The invention provides an organopolysiloxane having at least one polyhydric pendant group bonded to the silicon atom as derived from a polyglycerol compound. Such an organopolysiloxane is useful as a non-ionic surface active agent. The organopolysiloxane can be prepared by the hydrosilation reaction between an organohydrogenpolysiloxane having at least one hydrogen atom directly bonded to the silicon atom and a polyglycerol compound having an aliphatically unsaturated linkage in the molecule such as those obtained by the reaction of allyl alcohol and glycidol or by the reaction of diglycerin and allyl glycidyl ether.
