Fabric Softener

A laundry additive that gives fabrics a soft feel and smooth surface, reduces static electricity and wrinkling, and makes ironing easier. Most fabric softeners are designed for addition to the wash, rinse, or drying cycles. Wash- and rinse-added types are liquids; dryer-added fabric softeners come as sprays, impregnated tear-off sheets, and impregnated foam (porous) sheets, or as a slow-dispensing solid bar that attaches to the fin of a dryer. The softening agent most commonly used is a cationic quaternary ammonium compound. A fluorescent whitening agent or bluing is frequently included, as well as fragrance. Infrequently, antimicrobial ingredients are added. Fabric softening ingredients also are incorporated in some laundry detergent products.
