Abstract (en)

[origin: EP0714976A1] The present invention concerns a granular detergent composition or composition comprising anionic surfactant, at least 20% by weight of water-soluble cationic surfactant, and less than 10% by weight of anionic polymer wherein the molar ratio of anionic surfactant to cationic surfactant is less than 1:1, preferably less than 0.5:1. Another aspect of the present invention is a process for making the composition or component comprising the steps of (i) mixing an aqueous solution comprising water-soluble cationic surfactant, anionic surfactant, and less than 10% by weight of anionic polymer (ii) drying the mixture to form a concentrated solution having a solids level of at least 50% by weight, and (iii) granulating the concentrated solution; wherein the cationic surfactant is at a level of at least 20% by weight of the composition or component and the molar ratio of anionic surfactant to cationic surfactant is less than 1:1.
