Abstract
The present invention generally relates to a textile softening composition which comprises, as the softening agent, a quaternary ammonium salt which comprises a mixture of mono-, di- and tri-ester components, wherein the amount of diester quaternary is greater than about 50% by weight, and the amount of triester quaternary is less than about 25% by weight based on the total amount of quaternary ammonium salt. The invention also relates to a softening agent which comprises a high diester quaternary ammonium salt mixture comprising mono- and diester components derived for ether dialkanolamines. The invention also relates to processes for preparing said softening agents, and methods of use as a fabric softener and as a hair and skin conditioner.
