New alkanolamine esters, useful for cationic surfactants and esterquats for treating textile, paper and hair fibers and fabric softeners, are obtained by reacting alkanolamine with dicarboxylic acid and optionally alkoxylated fatty alcohol

摘要

Novel alkanolamine esters based on the esterification reaction of alkanolamines, optionally alkoxylated, dicarboxylic acids and fatty alcohols. optionally alkoxylated, as well as the cationic surfactants and esterquats obtainable therefrom, are described. The cationic surfactants and esterquats thus obtained exhibit a high degree of efficacy in softening and conditioning natural and synthetic fibres such as textiles, paper and hair, and are therefore usable in treatments for softening and conditioning the said fibres. Novel aqueous fabric-softening compositions which contain the cationic surfactants and esterquats mentioned, optionally in combination with other active softening substances, are also described.
