Abstract
A process for producing absorbent granules from sodium tripolyphosphate or disodium hydrogen orthophosphate by simultaneously granulating and hydrating the salts to full hydration. The process produces granules which have good absorbency without the need for a drying step. The granules can be used for absorbing liquid nonionic surfactant or other liquid components of detergent powders such as perfumes.
