Abstract: A clear single phase composition contains 40-95% by weight of a cyclic or short chain linear methyl siloxane and water, and 5-60% by weight of a cationic surfactant and a nonionic surfactant. The cyclic or short chain linear methyl siloxane in the single phase composition has an average structure or droplet diameter of less than about 50 nanometer. The single phase composition spontaneously provides optically clear one phase silicone microemulsions when combined with only hand agitation. The clear single phase compositions are useful in personal care and textile applications.
