Abstract
Abstract A fabric softener composition, which can pass through the wash cycle of a clothes washer, comprises a fabric softener, polystyrene, a plasticizer, and a long chain alcohol. The fabric softener composition is particularly suitable in combination with a web substrate, preferably a web substrate containing liquid laundry detergent to provide a single product for washing and softening clothes.
