Abstract
A first slurry containing alkyl benzene sulfonate is spray-dried to form dry, powdery particles which are introduced into a rotary drum mixer along with dry, powdery particles of other detergent ingredients. The dry, powdery particles are lifted and dropped in the mixer to form a descending curtain into which is sprayed a second slurry containing alpha olefin sulfonate, thereby agglomerating the ingredients into composite particles, each of which contains all the ingredients introduced into the mixer.
