PSEUDO-CERAMIDES

摘要

The proposal is for novel pseudo-ceramides of the formula (I) in which R<1> is a linear alkyl and/or alkenyl radical with 6 to 30 carbon atoms, R<2> is hydrogen or a possibly hydroxy-substituted alkyl radical with 1 to 30 carbon atoms, R<3> is an oligo-hydroxyalkyl radical with 4 to 12 carbon atoms and 3 to 10 hydroxyl groups or a glycosyl radical, X is a linear or branched alkylene radical with 1 to 6 carbon atoms, Y is oxygen, sulphur or an NR<4> radical and R<4> is hydrogen or an alkyl radical with 1 to 30 carbon atoms. The substances are suitable as "synthetic barrier lipids" for the production of skin-care agents.
