ABSTRACT:
Water-in-oil emulsions of improved stability are prepared by using an emulsifying composition comprising the combination of a finely divided montmorillonite mineral sufficiently modified with quaternary ammonium cations containing 10 or more carbon atoms, per cation, to render the mineral compatible with the oil, a polar organic dispersing agent for the mineral, and a partial ester of a fatty acid of 10 to 20 carbon atoms and a saturated, aliphatic, polyhydric alcohol having 3 to 18 hydroxyl groups, at least 2 of said hydroxyl groups being unesterified. In a preferred embodiment, useful, for example, in preparing an emulsion of an aqueous solution of aluminum chlorohydrate in cyclomethicone, the emulsifying composition is the combination of (a) a gelatinous dispersion of stearalkonium hectorite, with propylene carbonate dispersing agent, in isopropyl myristate, and (b) polyglyceryl-4 oleate.
