摘要： The present invention provides a solid composition comprising a polysaccharide and a hydrophobic compound having a melting point of between 30° C. and 90° C. The solid composition may further comprise a quaternary ammonium compound, wherein the weight ratio of the polysaccharide and the hydrophobic compound is between 1:50 and 50:1. Preferably, the solid composition is substantially free or completely free of water. The solid composition shows excellent stability at a temperature up to 45° C. The present invention also provides a process for preparing the solid composition and a liquid composition comprising said solid composition, and a method for conditioning a fabric by using said solid composition or said liquid composition as well.
