Abstract: The invention provides a process for preparing sphingolipids, compositions comprising sphingolipids and further components, and for the use of the compositions.

Abstract: Hydroxy-substituted sphingolipids are useful as constituents in cosmetic formulations. A method for preparing the sphingolipids involves reacting a lysosphingolipid with a hydroxycarboxylic acid or an intramolecular cyclic ester of a hydroxycarboxylic acid. The sphingolipids can be used for therapy or prophylaxis of cell damage, including skin cell damage and cell damage induced by UV radiation.
