Abstract
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.
Claims17
A cosmetic or pharmaceutical composition comprising an oil-containing biliquid foam dispersed in a salt-containing aqueous phase, the aqueous phase comprising a polymeric sulfonic acid gellant which is ammonium poly(acryldimethyltauramide-co-vinylformamide) and having a pH of less than 7, the salt contained in the aqueous phase being present in the composition in an amount in the range of from about 1 about 10 percent, the gellant being present in the composition in an amount in the range of from about 0.01 to about 10 percent, and the composition comprising less than about 1 percent surfactant, wherein said weights are by weight of the total composition.
A cosmetic or pharmaceutical composition comprising a silicone-oil containing biliquid foam dispersed in a salt-containing aqueous phase, the aqueous phase having a pH of less than 7 and comprising an ammonium poly(acryldimethyltauramide-co-vinylformamide) gellant;
- the salt contained in the aqueous phase being present in the composition in an amount in the range of from about 1 to about 10 percent, the gellant being present in the composition in an amount in the range of from about 0.01 to about 10 percent, and the composition comprising less than about 1 percent surfactant, wherein said weights are by weight of the total composition.
A method of thickening a composition comprising biliquid foam dispersed in a salt-containing aqueous phase having a pH less than 7, comprising gelling the aqueous phase with a polymeric sulfonic acid gellant which is ammonium poly(acryldimethyltauramide-co-vinylformamide);
- the salt contained in the aqueous phase being present in the composition in an amount in the range of from about 1 to about 10 percent, the gellant being present in the composition in an amount in the range of from about 0.01 to about 10 percent, and the composition comprising less than about 1 percent surfactant, wherein said weights are by weight of the total composition.
