Sodium acid pyrophosphate is used as a starter for baking foods, controlling fermentation speed; used for instant noodles, reducing the time of rehydration of finished products, non-sticky; used for biscuits and cakes, shortening fermentation time, reducing product breakage rate, loose The gaps are neat and the storage period can be extended.

Electroplating industry is used to prepare electroplating solution, which can form complex with iron. Wool industry used as wool degreasing agent and wool bleaching agent. The paper industry is used for bleaching paper and vegetable fibres. Printing and dyeing industry as printing and dyeing, fine bleaching auxiliaries. Used as toothpaste additive in daily chemical industry, it can form colloid with calcium hydrogen phosphate and play a stabilizing role. It can also be used in synthetic detergent and production of products such as shampoo. As a softener in water treatment. As a rust remover in machining. Used as dispersant and emulsifier in chemical industry. It can also be used in water treatment agent, oil drilling and other aspects, as a quality improver, emulsifier, buffer agent, chelating agent and so on in the food industry.
Sodium pyrophosphate has the function of soften water, but also can dissolve the insoluble salts of calcium and magnesium, such as clothing fiber, mixed with insoluble calcium soap or other metal soap formed dirt, it can make its redissolve and improve deconstain ability. In addition, sodium pyrophosphate has the effect of counter-flocculation to emulsify oil, which is called colloidal property. It can also make the surfactant solution further reduce the surface tension and interfacial tension, and play the role of washing aid.
