ABSTRACT:
The invention relates to mixtures of amidated fatty acids or derivatives thereof of the general formula ##STR1## wherein R' is absent or an alkyl group with 2-4 C-atoms, the average value of n is 0,5 to 3 and R represents a fatty acid radical with 14-24 C-atoms obtained from oils produced from the plant species `Brassica` with an eruca acid content lower than 5%.
These products are good thickeners for surfactants and/or detergents. No nitrose compounds of (di)alkanolamines, which could present a health hazard, are formed in the thickeners according to the invention.
