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.
Claims4
A fatty amide derivative of the formula XXI:
- wherein
- G is an aliphatic C8-C24 radical having an unbranched carbon chain which contains one or more groups of the formula XXII:
- wherein
- R19 is C1-C4-alkyl or hydrogen,
- R16 is a hydroxyl-and/or amino-substituted hydrophilic radical having 2 to 40 carbon atoms or a C1-C14-alkyl radial which has carboxyl and/or sulfo groups in the form of the free acids and/or their alkali metal or ammonium salts and which may be interrupted by nonadjacent oxygen atoms,-NH groups and/or N-C1-C4-alkyl groups, and
- R17 is an unsubstituted C1-C6-alkyl radical or a radical R16.
