Calcium citrate tetrahydrate

Calcium Citrate Tetrahydrate (CAS 5785-44-4) is the calcium salt of citric acid, commonly referred to as calcium citrate or calcium citrate hydrate. It is registered under EC 629-915-9 and supplied as a white powder suitable for use across food, pharmaceutical, and personal care applications.

In food and nutrition manufacturing, it functions as a pH buffer and calcium fortification agent, stabilising acidity in processed foods and beverages by neutralising excess acid without introducing off-flavours. In pharmaceutical formulations, it serves as an excipient and antacid active, while in personal care products it acts as a skin conditioner and antimicrobial support agent by chelating metal ions that would otherwise accelerate oxidative degradation.

Calcium Citrate Tetrahydrate is available in food-grade and pharmaceutical-grade specifications, with compliance to FCC and Ph.Eur. monographs depending on grade. It falls under REACH registration requirements for EU supply. Standard packaging includes 25 kg bags, with bulk options available on request.
