Abstract: The present invention provides silicone-water emulsions formed from volatile cyclic polysiloxanes which are emulsified with a preblended mixture of water and a combination of emulsifying agents. Highly ethoxylated nonionic emulsifying agents are particularly well-suited for the formation of stable silicone-water emulsions from volatile cyclic polysiloxanes. These volatile silicone-water emulsions can be combined with epidermal enhancing agents for cosmetic and medicinal purposes.
