Abstract
Fatty acid derivatives based on epoxidized unsaturated fatty acid esters or triglycerides and reacted with amines such as hydroxy- and/or amino-substituted hydrophilic amines or amino acids and/or with alkanols or with water on the epoxy group and/or the carboxylic ester groups are described. These fatty amides are suitable as surfactants in detergents and cleaners.
