Sodium trimetaphosphate (STMP) is an inorganic compound. Its CAS NO. is: 7785-84-4. It is colorless crystal or white powdery solid, soluble in water, and the solution is alkaline. Sodium trimetaphosphate is a weak reducing agent and can react with oxidation under acidic conditions.
Applications:
Food grade: Sodium trimetaphosphate (STMP) can be used as food antioxidant, food leavening agent and food stabilizer. It prevent food discoloration and vitamin decomposition, etc.
Other uses: AUCO brand STMP can be used in the preparation of industrial cross-linked starch and is an excellent inorganic surfactant. It has strong complexing ability and can be used as a water softener. STMP is also a raw material for the production of high-grade toothpaste and acts as an abrasive.
