Siliconate treated sodium tripolyphosphate for liquid detergent formulations |
摘要 |
A sodium tripolyphosphate employed for the formulation of detergent compositions with a water content ranging from 0.8 to 6% in the form of hexahydrate crystals and containing 0.2 to 2% by weight of siliconate. Also, a process for the preparation of such a sodium tripolyphosphate comprising spraying an aqueous solution containing between 5 and 10% of siliconate at weight onto a sodium tripolyphosphate containing at least 50% of phase 1 and having a particle diameter distribution ranging from 600 to 2,500 microns; and grinding the hydrated tripolyphosphate containing the siliconate to a mean particle diameter ranging from 80 to 200 microns.
