Magnesium Phosphate Dibasic is produced by reacting magnesium hydroxide or magnesium oxide with phosphoric acid under controlled conditions to form the trihydrate crystalline form. It serves as food additive E343(ii) in the EU and is GRAS-listed under FDA 21 CFR 184.1434. Its low water solubility provides stable mineral fortification without affecting product taste.
This makes it particularly suitable for dry powder applications where moisture control is critical. Common uses include infant formulas, medical nutrition, sports supplements, pharmaceutical tablets as an excipient/filler, and dental products. In addition to mineral fortification, it functions as an anticaking agent in powdered mixes, a free-flow agent in spice blends, and a mild abrasive in toothpaste. Food-grade Magnesium Phosphate Dibasic conforms to Food Chemicals Codex (FCC), JECFA, and USP specifications.
