Abstract
Water in silicone emulsions, methods for preparing the emulsions, and personal care products containing the emulsions are disclosed. The silicone phase of the water in silicone emulsions contains an emollient, a silicone elastomer containing a hydrophilic group, and an optional nonionic surfactant. The aqueous phase contains an anionic surfactant at such a concentration to provide a weight ratio of the silicone elastomer to anionic surfactant ranging from 60/1 to 1/1 in the water in silicone emulsion. The resulting water in silicone emulsions can be used in a variety of personal care, household and health care formulations, and in particular for sprayable lotions.
