Abstract:
A composition comprising a non-aqueous polar solvent-in-oil-in-water multiple emulsion of the type PS.sub.1 /O/W which contains a non-aqueous polar solvent phase PS.sub.1 dispersed in a silicone oil as a first continuous phase of a primary emulsion PS.sub.1 /O by an emulsifier, the primary emulsion PS.sub.1 /O being dispersed in a second continuous aqueous phase W to form the multiple emulsion PS.sub.1 /O/W, the emulsifier being a crosslinked elastomeric silicone polyether constituting polymeric molecules crosslinked together to form a gel consisting of three-dimensional molecular polymeric networks containing crosslinking units between and among the polymeric molecules, the crosslinked elastomeric silicone polyether further containing and being swollen by about 65 to about 98 percent by weight of the silicone oil.
