Biodegradable amidoaminoesters

Disclosed is a process for making di(acyloxyalkyl) di(alkyl) ammonium compounds useful as fabric softeners. The corresponding di(hydroxyalkyl) tertiary amine is diesterified under conditions determined to minimize the formation of monoester side product and then the diester is quaternized under conditions effective to minimize degradation of the quaternized diester.
