Abstract
A gel composition which comprises a specific type of cyclic dimethyl polysiloxane, an animal or plant oil or vaseline, and an ester of dextrin with a fatty acid having from 8 to 20 carbon atoms. The cyclic dimethyl polysiloxane is methyl-substituted cyclotetrasiloxane, cyclopentasiloxane or cyclohexasiloxane. The use of this type of cyclosiloxane contributes to impart good spreadability on the skin to the composition.
