Abstract:
1. A three-phase emulsion consisting essentially of an emulsifier, one oily outer phase and two aqueous inner phases, one of said inner phases being an aqueous gel having a viscosity greater than 2,000 cPs as measured on a Brookfield LV at 6 rpm, and an emulsifier, wherein said emulsifier is selected from the group consisting of lipoamino acids and their salts; lipopeptides and their salts; sorbitan esters; polyglycerol esters; ethoxylated hydrogenated castor oil; glycerol stearate; polyglycol or polyglycerol polyhydroxystearates; ethoxylated sorbitan esters; protein acylates; ethoxylated beeswax; cationic emulsifiers; ethoxylated or non-ethoxylated methylglucoside esters; ethoxylated fatty acids; ethoxylated fatty alcohols; decylphosphate or cetearylsulfate; aluminum polyoxystearate; magnesium stearate; aluminum stearate; an emulsifier comprising: an emulsifier comprising: p is a decimal number between 1 and 5, X is the xylose residue, and R is a branched alkyl radical: in which m is an integer between 6 and 18, n is an integer between 4 and 18 and the sum n+m is greater than or equal to 14; a composition consisting of a mixture of at least two emulsifiers of the formula R—O—(X) p ; and a composition comprising: more than 0% by weight and less than 100% by weight of at least one emulsifier of the formula R—O—(X) wherein the aqueous gel comprises a polymer which is a homopolymer or copolymer of acrylic acid, acrylic acid derivatives, acrylamide or acrylamidomethanepropanesulfonic acid, and wherein the oily outer phase comprises an oil in an amount of at least 2% by weight and at most 20% by weight of the emulsion.
