Abstract:
The present invention relates to a method for conditioning a fabric comprising the step of contacting the fabric with an aqueous medium comprising a composition, wherein the composition comprises: (a) a quaternary ammonium compound; (b) a cationic polysaccharide; and (c) a nonionic polysaccharide. In particular, the quaternary ammonium compound is a biodegradable quaternary ammonium compound. The composition has excellent softening performance and improved perfume longevity. The present invention also relates to use of said composition for conditioning a fabric.
