Patent ID: 7638478

Claim:
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 0.001 to 8% wt of a first anionic surfactant, to form an aqueous silicone mixture in emulsified form; (ii) contacting the aqueous silicone mixture with clay, to form a mixture of clay and silicone; (iii) further mixing the mixture of clay and silicone; (iv) contacting the mixture of clay and silicone with 1 to 10% wt of a second anionic surfactant and optionally additional water; (v) further mixing the mixture of clay and silicone and second anionic surfactant to form a wet agglomerate; (vi) removing the wet agglomerates having a size greater than 1400 micrometers by sieving; (vii) drying and optionally cooling the wet agglomerate; and (viii) removing the dried agglomerates having a size less than 250 micrometers by sieving or elutriation, wherein the first anionic surfactant is different from the second anionic surfactant.
