Abstract
The present application relates to a method of producing an amide product mixture having a low content of secondary amines by reacting an amide product mixture having a high secondary amine content with an aliphatic alkylene oxide in the absence of an essential amount of any alkoxylation catalyst. The amide product mixture obtained contains a minor amount of tertiary amines and exhibits advantageous properties when used for the formulation of cosmetic products, such as shampoos and creams; foam cleaning compositions, e.g. for textiles and cars; and functional fluids, such as lubricants, metal working fluids and hydraulic fluids.
