Soya Fatty Acid Diethanolamide (Soyamide) is a nonionic surfactant produced by the reaction of soybean-derived fatty acids with diethanolamine. Compared to Coconut Fatty Acid Diethanolamide, it contains a higher proportion of unsaturated fatty acids such as oleic acid and linoleic acid, which may contribute to improved emollient properties and enhanced skin compatibility in certain formulations.
