Description

Magnesium Phosphate, Tribasic Pentahydrate is a high-purity inorganic salt essential for applications requiring a controlled-release source of magnesium and phosphate ions. Its value lies in its consistent quality and stability, making it a reliable functional ingredient in critical manufacturing processes. This compound is primarily needed by the pharmaceutical, food & beverage, and nutritional supplement industries for its role as an excipient, nutrient fortifier, and antacid agent.

Application

• Pharmaceutical Excipient: Used as a binder, diluent, or disintegrant in tablet and capsule formulations.
• Nutraceutical & Dietary Supplements: Serves as a key source of bioavailable magnesium and phosphorus in mineral supplements.
• Food Additive (FCC Grade): Functions as a nutrient fortifier, pH regulator, and anti-caking agent in food products.
• Antacid Preparations: An active ingredient in formulations designed to neutralize stomach acid.
• Ceramics & Glass Manufacturing: Acts as a source of magnesium oxide and phosphorus pentoxide in specialty glass and ceramic frits.
• Laboratory Reagent: Utilized in analytical chemistry and research as a standard or buffer component.
• Dental Cements: A component in certain types of dental cement formulations.
• Fire Retardant Additive: Incorporated into materials to enhance flame resistance.
