Trimagnesium dicitrate

Trimagnesium dicitrate (CAS 3344-18-1), also known as magnesium citrate, is the trimagnesium salt of citric acid used across food, pharmaceutical, and personal care manufacturing. It functions as a pH buffer, chelating agent, and mineral fortification source in finished formulations. In dietary supplements and functional foods, it delivers bioavailable magnesium while buffering product pH.

This dual functionality reduces the need for separate acidulants or mineral salts. Pharmaceutical manufacturers use it as an active ingredient in laxative formulations and as a magnesium source in oral solid dosage forms. In food processing, it stabilizes sensitive ingredients by sequestering trace metal ions. This prevents reactions that would otherwise accelerate oxidation or discoloration in the final food product.

Personal care formulators incorporate it as a chelating agent in rinse-off and leave-on products. This helps to improve preservative efficacy and control mineral interference from hard water sources. Trimagnesium dicitrate is supplied as a white to off-white powder in both anhydrous and hydrated forms. Standard commercial grades include food-grade (FCC), USP, and Ph. Eur. specifications.

These standards support use across regulated pharmaceutical and food applications. Bulk quantities are typically available in 25 kg bags, with documentation packages suited to GMP procurement requirements.
