CA 2230298

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.

L'invention concerne des compositions assouplissantes pour textiles qui forment et maintiennent des dispersions aqueuses stables sans adjonction de parfum huileux. La stabilité de ces compositions basées sur un mélange d'une amido-amine, telle que la bis(suif-amidoéthyl)-2-hydroxyéthylamine, et d'un assouplisseur de tissu à diester quaternaire, tel que le sel d'ammonium quaternaire de N-méthyle N,N,N-triéthanolamine disuif ester, est améliorée par l'ajout à la composition d'un ou plusieurs esters gras d'un acide gras ou d'un alcool gras, tel que le monostéarate de glycérol.
