ABSTRACT:
A dry, brittle detergent product of cellular particulate structure is produced with a bulk density between 0.25 and 0.40 gms/cc by forming the components of the detergent composition into an aqueous slurry mass and subjecting such mass to microwave irradiation for a sufficient period to cause boiling of labile water, intumescense of the mass and the formation of the product in question. Boiling of the labile water under the action of microwaves effects evaporation of such labile water but does not affect water of crystallization.
