Abstract
Abstract Phosphoric acid esters, which are anionic anti-static agents, are incorporated into conventional cationic fabric softeners for addition to the rinse cycle of automatic home laundry machines or for the final rinse in an industrial fabric treating process. The static electricity accumulation of synthetic fabrics, especially nylon, is reduced to substantially the same degree as cotton and softening is enhanced. The compositions are preferably in the form of aqueous solutions, dispersions or emulsions.
