    Patent number: 6562780
    Abstract: Esters derived from alkanolamines, dicarboxylic acids and fatty alcohols and the cationic surfactants obtainable therefrom. 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 fibers such as textiles, paper and hair, and are therefore usable in treatments for softening and conditioning the said fibers. Novel aqueous fabric-softening compositions which contain the cationic surfactants and esterquats mentioned, optionally in combination with other active softening substances, are also described.
