Abstract
The invention relates to new lipophilic hydroxylated acids wherein said lipophilic hydroxylated acid comprises a hydrophobic hydrocarbon chain having from 7 to 30 carbon atoms grafted onto the hydroxyl functional group and/or the acid functional group of the lipophilic hydroxylated acid via a covalent bond chosen from the group consisting of an ester bond on the hydroxyl functional group, an anhydride bond on the acid functional group and an amide bond on the acid functional group, provided that, in the case of an amide bond, this hydrophobic hydrocarbon chain consists of an alkyl radical having from 10 to 30 carbon atoms resulting from a monoamine, or a combination of these bonds. These new derivatives are useful as active ingredient of cosmetic or pharmaceutical compositions and as emulsifying agents.
