Sodium citrate dihydrate

Sodium citrate dihydrate (CAS 6132-04-3) is the dihydrate salt form of citric acid, commercially known under names including Trisodium Citrate, N 1560, and TSCF 6000. It dissociates in solution to release citrate ions, which act as both a pH buffer and a chelating agent across multiple industrial sectors.

In food and beverage manufacturing, it regulates acidity in processed cheeses and carbonated drinks by maintaining stable pH ranges between 6.5 and 8.5. In pharmaceutical formulations, it sequesters calcium and magnesium ions to prevent mineral-induced degradation of active ingredients. Personal care formulators use it to stabilise emulsions and condition skin by moderating ionic activity at the surface level.

Sodium citrate dihydrate is available in food-grade and pharmaceutical-grade specifications, compliant with FCC, Ph.Eur., and REACH requirements. It is supplied as a white crystalline powder and typically offered in 25 kg bags or bulk quantities. Procurement teams should confirm grade suitability against application-specific regulatory requirements.
