Abstract:
A process for preparing a granular detergent composition comprising:(a) thoroughly mixing a crystalline anionic surfactant paste selected from the group consisting of C.sub.12 -C.sub.18 coconut fatty alcohol sulfates, C.sub.14 C.sub.15 synthetic alkyl sulfates and mixtures thereof, with a sufficient amount of fine powders selected from the group consisting of soda ash, sodium sulphates, aluminosilicates, crystalline layered silicates, phosphates, precipitated silicates, polymers, carbonates, citrates, nitrilotriacetates, powdered surfactants, recycle fines of fine powders and/or free flowing agglomerates and mixtures thereof, to form a free flowing agglomerate;(b) thoroughly mixing a product of the step (a) with a non-crystalline anionic surfactant paste selected from the group consisting of alkyl ethoxy sulfates, alkyl benzene sulfonates and mixtures thereof, to form a free flowing agglomerate, wherein the agglomerate from step (b) includes less than about 20% of granules having a diameter larger than 1180 .mu.m.
