Abstract
In the manufacture of detergent powders containing alkoxylated alcohols, the problem arises that the alcohols cannot be spray-dried with the rest of the constituents. The invention provides a method of incorporating the alcohols into the spray-dried powder in such a way that staining of the packages does not occur. This is done by adding the alcohols in the form of a solution which combines with the residual water in the powder to form a gel.
