<p>A nonionic loaded powder detergent composition which is free-flowing is manufactured and agglomerated in a single operation by mixing sodium carbonate, a di- or tricarboxylic acid and a nonionic surfactant to form a nonaqueous slurry. Water is then added to the slurry to solubilize portions of the sodium carbonate and the di- or tricarboxylic acid which allows them to react to form a builder salt in the slurry. Silica is then added to the slurry to form a flowable or nearly flowable powder detergent mixture. A second portion of sodium carbonate may be added after the silica.</p> |
