Abstract
The present invention relates to compositions consisting essentially of a narrow dispersity trimethylsilylated silica in a volatile and/or non-volatile silicone-aliphatic hydrocarbon hybrid fluid. Improvements in the range of properties and benefits, which the mixtures of the present invention may provide, include a broad range of viscosities, from about 100 cs to about 10000 cs, a higher % trimethylsiloxysilicate, a wider range of sensory profiles, and non-occlusivity or occlusivity. In all cases the mixtures are both clear and safe for human contact.
