The present invention provides a process for making detergent granules by forming a doughy mass comprising surfactant and/or water-soluble organic polymer and/or detergent builder, and then granulating by mixing a deagglomerating agent into the doughy mass at a high shear rate. Neutral or alkaline salt, detergent builder and other conventional detergent ingredients can be, and preferably are, kneaded into the doughy mass before addition of the deagglomerating agent. The deagglomerating agent is a fine powder having a mean particle size of less than about 200 microns and is most preferably sodium aluminosilicate.

Formation of detergent granules by deagglomeration of detergent dough

This is a process for making high active alkyl sulfate particles which are dispersible in cool or cold water. The process includes applying mechanical work to low moisture, neutralized C.sub.12-18 alkyl sulfate paste. Included are detergent particles made by this process and a method for washing fabrics at cool or cold water temperatures using detergent particles made by this process.
