Abstract
Fabric softening compositions which form and maintain stable aqueous dispersions in the absence of added oily perfume are disclosed. The stability of aqueous fabric softener compositions based on a mixture of an amido amine, such as bis(tallow amidoethyl)-2-hydroxyethyl amine and a quaternary diester fabric softener, such as N-methyl, N,N,N-triethanolamine ditallow ester quaternary ammonium salt is enhanced by inclusion in the composition of at least one fatty ester of a fatty acid or fatty alcohol, e.g., glycerol monostearate.
