Abstract
The present invention relates to method for preparing composition containing at least a quaternary ammonium compound, a cationic polysaccharide, a fragrance material or perfume, a nonionic surfactant, and optionally a nonionic polysaccharide. The method notably comprises a step of preparing a premix of the fragrance material or perfume and the nonionic surfactant. Said composition may notably be used for fabric conditioning.
