Abstract
Abstract A fabric conditioning formulation is disclosed which is an aqueous emulsion of a cationic fabric softening material. This invention discloses the use of low temperature stabilizers for such emulsions including moderate molecular weight quaternary ammonium compounds and a number of nonionic and amphoteric materials. Preferably the moderate molecular weight ammonium compound is used in combination with one or more of the nonionic, anionic, or amphoteric substances. Optical brightening agents suitable for use in fabric softening formulations are also discussed.
