ABSTRACT:
A heavy duty built synthetic organic detergent powder is made without the need for phosphates or carbonates in the formulation thereof by preparing a base product, such as by spray drying an aqueous mix of an anionic synthetic organic detergent and alkali metal silicate, for example, a crutcher mix of higher linear alkyl benzene sulfonate, sodium silicate, sodium sulfate and water, in certain proportions, spraying a nonionic detergent onto the dry base and blending with it a powdered anti-redeposition agent. The product made is a free-flowing detergent of desired density and particle size and the process is readily effected in a tumbling drum or twin shell blender without producing excessive lumping or tackiness.
