The invention relates to cosmetic or pharmaceutical composition comprising an oil-containing biliquid foam dispersed in a salt-containing aqueous phase, in which the aqueous phase, having a pH of less than about 7, is gelled by a polymeric sulfonic acid. A particularly preferred gellant is ammonium poly(acryldimethyltauramide-co-vinylformamide). Unlike many other types of gels, these gels are stable at an acid pH in the presence of substantial amounts of electrolytes, and therefore are useful in delivering acidic active components.

Gelled aqueous cosmetic compositions

The invention relates to a water-thin emulsion comprising a non-phospholipid, non-ethoxylated pseudoemulsifier system, the system having a chemical composition with at least one hydrophobic moiety and at least one polar moiety, the size, shape and/or planar arrangement of the hydrophobic and polar moieties being asymmetrical with respect to each other. The emulsion of the invention is prepared by high-pressure homogenization of a crude oil and water emulsion containing the pseudoemulsifier. The emulsions require little or no traditional emulsifier to maintain stability, and are particularly useful in the preparation of multiple emulsions.

Water-thin emulsions with low emulsifier levels

The invention relates to multiple emulsions comprising a primary emulsion in an external phase, and comprising a principle water phase and a principle oil phase, the multiple emulsion containing no more than about 1% of an emulsifier having an HLB of about 16 to about 20.
