Oil-in-water emulsions containing an auto-emulsifiable composition based on a fatty alcohol and on an alkyl polyoside and a co-emulsifying agent

A cosmetic or dermatological composition in the form of a stable oil-in-water emulsion, comprising

• (a) from 5 to 40% by weight of an oily phase optionally containing, in an amount less than 15% by weight, at least one vegetable oil containing more than 40% by weight of linoleic acid triglycerides,
• (b) from 0.5 to 5% by weight of an auto-emulsifiable composition containing from 60 to 90% by weight of at least one fatty alcohol having from 12 to 22 carbon atoms, from 10 to 40% by weight of an alkyl polyoside, the alkyl chain of which has from 12 to 22 carbon atoms,
• (c) from 0.5 to 4% by weight of at least one co-emulsifying agent selected from the group consisting of a fatty alcohol having from 14 to 22 carbon atoms, a fatty acid having from 14 to 22 carbon atoms, an alkyl glyceryl ether, the alkyl chain of which has from 14 to 22 carbon atoms, a compound of formula:
• ##STR3## wherein R' and R", each independently, represent a cholesteryl, behenyl or 2-octyldodecyl radical, and a mixture thereof, with the proviso that when a single co-emulsifying agent is present, said single co-emulsifying agent is present in an amount equal to or less than 2 weight percent, the remainder consisting essentially of an aqueous phase.
