Magnesium Oxide
Formula:
MgO
GOST/CAS:
CAS 1309-48-4
Pharmaceutical Grade Magnesium Oxide (calcined magnesia, light/heavy) is a highly purified inorganic compound appearing as a fine, odorless white powder. It is practically insoluble in water but readily dissolves in dilute acids. Due to its exceptional chemical purity, absence of toxic impurities, and stable structure, this product serves as an indispensable active ingredient and excipient in the manufacture of pharmaceuticals, dietary supplements (nutraceuticals), premium cosmetics, and specialized food products.
Applications
Pharmaceutical Industry: Used as an active pharmaceutical ingredient (API) in antacid formulations to neutralize gastric acid. It serves as a highly bioavailable source of magnesium in vitamin-mineral complexes and acts as an effective excipient (filler, glidant, and anti-adherent) in tableting and encapsulation processes.
Nutraceuticals & Sports Nutrition: Acts as a core component in dietary supplements aimed at supporting the nervous, muscular, and cardiovascular systems, regulating electrolyte balance, and preventing muscle cramps.
Cosmetics & Personal Care: Incorporated into premium formulations of face powders, talcs, dry shampoos, masks, and color cosmetics. It efficiently absorbs excess sebum, enhances product texture, provides a matte finish, and offers mild antiseptic properties.
Food Industry (Food Additive E530): Utilized as an emulsifier, anticaking agent, and free-flow agent in powdered products such as dry milk blends, creamers, cocoa powder, and other granulated food items.
Key Advantages
Exceptional Purity (Ph. Eur. / USP Compliance): Fully meets strict international pharmacopeia standards. Minimal heavy metal, arsenic, and foreign impurity content guarantees the absolute safety of the end product.
Excellent Technological Properties: Features optimal flowability and controlled bulk density (available as light or heavy grade depending on specification), ensuring precise dosing and matrix stability during compression and encapsulation.
High Bioavailability & Neutralizing Capacity: Effectively binds excess stomach acid and maintains stable, predictable therapeutic action within medical formulations.
Safe and Hypoallergenic: Non-toxic, chemically inert, and non-irritating to the skin when used in cosmetics. It is entirely safe for human consumption when used according to regulatory dosages.
Storage & Transportation
- Store in dry, cool, well-ventilated warehouses in the manufacturer's tightly sealed original packaging.
- Product is highly hygroscopic! Protect from moisture, condensation, and direct sunlight, as magnesium oxide readily absorbs water and carbon dioxide from the air, converting into magnesium carbonate/hydroxide.
- Recommended storage temperature range: from +5°C to +30°C.
- Transportation is permitted by all types of covered transport in strict accordance with freight regulations. The product is not classified as hazardous cargo (non-hazardous under ADR/DOT regulations).
