Abstract
A washing powder containing soap, normally in relatively large quantities, is made by combining a slurry containing washing powder components with a stream containing fatty acid or soap or a mixture of these. The fatty acid may be liquid or molten or in solution. The slurry is combined with the stream in such a way that the two are thoroughly admixed, for instance by feeding them to a pressurizing pump. When fatty acid is to be combined with the slurry, the latter will contain sufficient excess alkali to form soap in situ.
