摘要
Amides of an aliphatic polyamine with two or three molecules of 12-hydroxyoctadecanoic acid, wherein the polyamine comprises at least one primary amino group for each molecule of 12-hydroxyoctadecanoic acid and additionally at least one secondary and/or tertiary amino group, can be used in a lipase stable thickener composition comprising from 50 to 95% by weight of one or more of the amides, from 5 to 50% by weight of one or more diluents and from 0 to 10% by weight water, and such thickener compositions can be prepared by a step of heating a starting mixture comprising hydrogenated castor oil and one or more aliphatic polyamines and adding one or more diluents before or after the heating step.
