ABSTRACT:
The present invention relates to water-free, co-solvent free, stable, dispersions of certain polydimethylsiloxanes in certain nonionic, poloxamer surfactants; wherein:
a. the dispersed polydimethylsiloxanes, which are insoluble in said surfactant, are oriented by the surfactant such that when dispersed in water they are particularly adept at forming oriented, monolayer coatings on various substrates, and
b. the particle size of the dispersed polydimethylsiloxane is from between about 0.5 and about 10 microns, with a particle size distribution such that from between about 80 and 95% of the dispersed polydimethylsiloxane is within this particle size range. These stable dispersions are described as ultramulsions, which, together with their physical properties, distinguishes them from emulsions, microemulsions and solutions.
