Abstract

Abstract <IMAGE> (I) <IMAGE> (II) Non-ionic amphiphilic, glycerol-derived compounds having formula (I), where R is a radical selected from the group consisting of C4-28 branched or linear alkenyl or alkyl radicals or mixtures thereof, or is a -CH2A grouping in which A is -OR', -SR, (II) where R' is a saturated or unsaturated hydrocarbonated radical and n represents an average statistical value n greater than 1 and equal to or less than 6; and, when R' is a -CH2A radical, n is also 2. These compounds are surface-active agents and some may form vesicles.
