A cosmetic or dermopharmaceutical composition comprising as a surfactant, at least one nonionic amphiphilic compound having formula (I):
- ##STR30## wherein R represents a radical selected from the group consisting of
- (i) a linear or branched C.sub.4 -C.sub.28 alkyl or alkenyl, or a mixture thereof, and
- (ii) --CH.sub.2 A wherein A represents --OR', --SR' or ##STR31## wherein R' represents a saturated or unsaturated hydrocarbon, and n represents an average statistical value n greater than 1 and equal to not more than 6 and, when R represents --CH.sub.2 A, n also represents a value equal to 2.
A composition comprising a dispersion in an aqueous medium of vesicles bounded by one or more lamellae of a lipid phase containing at least one nonionic amphiphilic compound having formula (I):
- ##STR32## wherein R represents (i) a linear C.sub.14 -C.sub.18 alkyl radical or (ii) --CH.sub.2 A wherein A represents OR' wherein R' a linear C.sub.10 -C.sub.18 alkyl radical, and n represents an average statistical value n greater than 1 and equal to not more than 3 and, when R represents --CH.sub.2 A, n is also equal to 2.
