Abstract (en)
[origin: WO9516766A1] Viscosity stable, concentrated, aqueous, liquid fabric softening compositions contain a mixture of biodegradable diester quaternary ammonium softening materials and specific co-active fabric softening materials which include substituted imidazoline compounds and specific quaternary ammonium salts. The compositions have superior stability at both normal and lower temperatures. The best process for preparing such compositions uses a molten premix of the fabric softening materials which is dispersed in an aqueous phase through the use of high shear milling.
