Industrial Grade and Food Grade Tetrasodium Pyrophosphate

Industrial Grade and Food Grade Tetrasodium pyrophosphate Product Overview Anhydrous sodium pyrophosphate is a colorless transparent crystal or a white powder. The relative density of 1.824, the melting point of 880 °C. Soluble in water, insoluble in alcohol, its aqueous solution is alkaline, easy to weather, moisture absorption. With strong pH buffering, it has a certain chelating effect on metal ions. Anhydrous sodium pyrophosphate is mainly used as softener, printing and dyeing bleaching agent, wool degreasing agent, boiler scale remover, metal ion chelating agent, dispersant, printing and dyeing, and auxiliaries for fine bleaching of grass products. Synthetic washing additives. Oil well mud conditioner, additive for ABS resin. Used as a copper complexing agent in the bath. Sodium pyrophosphate decahydrate is mainly used as a toothpaste stabilizer. In the food industry as emulsifiers, buffers, chelators, gelling agents, stabilizers. When sodium pyrophosphate meets Ag+, it produces white silver pyrophosphate, while the reaction between orthophosphate and Ag+ produces a yellow orthophosphate precipitate, which is a characteristic reaction that distinguishes the two salts from each other. Edible sodium pyrophosphate has integration with metal particles, dispersion, flocculation, emulsification, prevention of lipids and oxidation, and casein viscosifying. When the Ph value is high, it has the effect of suppressing food spoilage.
