Abstract
A high solids slurry of surfactant, inorganic builders and filler salts, which may be spray dried to produce a granular laundry detergent, is prepared by contacting mixed organic and inorganic acids, such as produced in the first stage of the oleum sulfonation of detergent alkylates, with a dry alkali metal carbonate and then with water while subjecting the ingredients and reaction mixture to a controlled mulling/smearing action.
