ABSTRACT:
The present invention relates to a process for preparing a textile treatment auxiliary composition in particulate form, wherein the composition comprises anionic surfactant, clay and silicone, and wherein the process comprises the steps of: (i) contacting the silicone with water and a first anionic surfactant, to form an aqueous silicone mixture in emulsified form; and (ii) thereafter contacting the aqueous silicone mixture with the clay, a second anionic surfactant and optionally additional water to form a mixture of clay and silicone; (iii) further mixing the mixture of clay and silicone; and (iv) optionally drying and optionally cooling the mixture formed in step (iii).
