Abstract

A process for obtaining a sodium tripolyphosphate hexahydrate in microcrystalline form, characterized in that in the anhydrous tripolyphosphate which is to be subjected to crystallization from water, approximately 0.2-1% by weight, and preferably 0.3-, is introduced. 0.7% by weight of microcrystalline tripolyphosphate hexahydrate formed on a phase i support.
