Synthesis and property study of the new type betaine softener

Stearic acid reacted with triethanolamine to give triethanolamine stearate, which reacted with sodium chloroacetate to form a new type of betaine of triethanolamine stearate. The optimum process conditions for the synthesis were probed, and the properties were tested. The results demonstrated that the softness from this softener was near to that from aminosilicone, and the whiteness and wettability were superior to those from aminosilicone. The betaine type product is biodegradable and belongs to the eco products.
