• Uses: Sequestering and deflocculating agents, primar- ily in water treatment, food processing, and cleaning compounds; heavy-set detergent builders. sodium polyphosphate is a preservative against bacteria, molds, and yeasts. When used in high concentrations, it can cause skin irritation. Sodium hexametaphosphate has been used as a polyphosphate anion source to prepare hydrated calcium polyphosphate powder. It can be used as a deflocculant to prepare suspensions of kaolinite and ceramic grade kaolin.
