Abstract
Abstract Fabric washing compositions containing a surfactant, which is usually an anionic and/or nonionic surfactant, and optionally other conventional ingredients such as builders, bleaches etc additionally contain both cellulase and a clay, particularly a smectite clay, to provide a softening benefit on cellulosic fabrics. The compositions may also contain cationic antistatic agents.
