Abstract
Fabric conditioning compositions which impart softness and antistatic properties are provided for through-the-wash use in conjunction with machine dryers. The fabric conditioning compositions comprise complexes of specified tertiary amines and multi-functional carboxylic acids in combination with unreacted amine, the latter being present in an amount of at least 20% of the stoichiometric amount of tertiary amine required to form the complex.
