Abstract
A process for making washing powder having a high content of sodium soap in which the tendency to form clots and gels is reduced. The reduction is effected by impregnating spray-dried or spray-cooled powder with a specified amount of a water-soluble sodium salt. The amount specified is sufficient to produce a solution of sodium ions having 0.5 to 4 molar initial concentration in the immediate locality of the individual spray-dried particles.
