Abstract
Fabric conditioning aqueous liquid emulsions are provided which impart softness and antistatic properties to laundered fabrics as a wash-cycle additive for through-the-wash use or alternatively as a rinse cycle additive. The dispersed phase of the liquid emulsions comprise complexes of specified tertiary amines and multi-functional carboxylic acids in combination with unreacted amine and a minor amount of one or more specified alkyl cellulose ethers to enhance high temperature emulsion stability.
