Polar solvent-in-oil emulsions and multiple emulsions
First Claim
1. A composition comprising a non-aqueous polar solvent-in-oil emulsion containing a non-aqueous polar solvent phase dispersed in a silicone oil continuous phase by an emulsifier, the emulsifier being a crosslinked elastomeric silicone polyether which constitutes 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 containing and being swollen with about 65 to about 98 percent by weight of the silicone oil.

Abstract
One composition is a non-aqueous polar solvent-in-oil emulsion containing a non-aqueous polar solvent phase dispersed in a silicone oil continuous phase by an emulsifier. A second composition is a non-aqueous polar solvent-in-oil-in-water multiple emulsion of the type PS1 /O/w which contains a non-aqueous polar solvent phase PS1 dispersed in a silicone oil as a first continuous phase of a primary emulsion PS1 /O by an emulsifier. The primary emulsion PS1 /O is dispersed in a second continuous aqueous phase W to form multiple emulsion PS1 /O/W. A third composition is a non-aqueous polar solvent-in-oil-in-non-aqueous polar solvent multiple emulsion of the type PS1 /O/PS2 which contains a non-aqueous polar solvent phase PS1 dispersed in a silicone oil as a first continuous phase of a primary emulsion PS1 /O by an emulsifier. The primary emulsion PS1 /O is dispersed in a second continuous non-aqueous polar solvent phase PS2 to form multiple emulsion PS1 /O/PS2.
