Abstract

An improvement in the process for the production of spray dried detergents containing nonionic tensides where the aqueous detergent slurry containing from 50% to 90% by weight of the total solids of the final spray dried detergent and from 0 to 5% at the most by weight of the total solids of nonionic tensides is sprayed into a conventional spray drier and simultaneously at the area of the spray cone a watersoluble powder is injected consisting of the remainder of the total solids of the final spray dried detergent having at least one nonionic tenside deposited thereon as a granulate where the ratio by weight of solids to nonionic tenside amounts to 50:1 to 5:1; whereby larger amounts of nonionic tensides can be incorporated into the final spray dried detergent without increased heating costs.
