Abstract
A non-aqueous silicone emulsion containing a silicone phase and an organic phase is useful as a component in various personal care compositions. The silicone phase contains a crosslinked silicone elastomer and a low molecular weight silicone fluid and the organic phase contains an organic liquid.
Claims30
A non-aqueous silicone emulsion, comprising:
- a silicone phase, comprising a crosslinked silicone elastomer and a low molecular weight silicone fluid;
- and an organic phase, comprising an organic liquid wherein the organic phase comprises less than 50 parts by weight water per 100 parts by weight of the organic phase.
A method for making a nonaqueous silicone emulsion, comprising
- adding a silicone elastomer and a first portion of a low molecular weight silicone together, thereby forming a silicone gel, slurrying the gel with a second portion of the low molecular weight silicone to form a mixture having a desired particle size, thereby forming a silicone phase, and combining the silicone phase with an organic solvent to form the emulsion.
