ABSTRACT:
Stable emulsions of a polar liquid in a non-polar base liquid are prepared with the cooperating action of a mixture of a water-in-oil surfactant having an HLB value of from 2 to 10 and certain polydiorganosiloxane-polyoxyalkylene copolymers. An emulsion of interest is an anti-perspirant composition comprising an aqueous solution of aluminum chlorhydrate as the polar liquid dispersed in cyclopolydimethylsiloxanes as the non-polar base liquid, using a mixture of nonylphenoxy polyethoxyethanol and a copolymer of a trimethylsiloxane-endblocked polydimethylsiloxane containing a minor amount of methylhydrogensiloxane units and an allyloxy-endblocked polyoxyethylenepolyoxypropylene copolymer.
