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 PS 1 /O/w which contains a non-aqueous polar solvent phase PS 1 dispersed in a silicone oil as a first continuous phase of a primary emulsion PS 1 /O by an emulsifier. The primary emulsion PS 1 /O is dispersed in a second continuous aqueous phase W to form multiple emulsion PS 1 /O/W. A third composition is a non-aqueous polar solvent-in-oil-in-non-aqueous polar solvent multiple emulsion of the type PS 1 /O/PS 2 which contains a non-aqueous polar solvent phase PS 1 dispersed in a silicone oil as a first continuous phase of a primary emulsion PS 1 /O by an emulsifier. The primary emulsion PS 1 /O is dispersed in a second continuous non-aqueous polar solvent phase PS 2 to form multiple emulsion PS 1 /O/PS 2 . |
