Magnesium acetate

Magnesium acetate (CAS 142-72-3), also known as magnesium diacetate, is an inorganic salt used across pharmaceutical, food, and personal care manufacturing. It functions primarily as a pH buffer, catalyst precursor, and preservative agent in formulation and industrial processing. In pharmaceutical manufacturing, it acts as a buffering agent in tablet coatings and injectable formulations where controlled pH is critical to product stability. Personal care formulators incorporate it into skin care and hair care products to regulate acidity and extend shelf life.

As a catalyst precursor, it is used in polymerization and esterification reactions, particularly in the production of polyethylene terephthalate (PET) and other polyesters. In food processing, it serves as an acidity regulator and mineral supplement in fortified products and functional beverages. Magnesium acetate is supplied as a white crystalline powder or granules, typically in the tetrahydrate form. Standard grades include food-grade (FCC), pharmaceutical-grade (USP/BP), and technical-grade material to suit different application requirements.

Bulk supply is available in multi-kilogram bags through to pallet quantities for industrial procurement. This versatile chemical ensures high purity and consistency for demanding manufacturing environments across global supply chains. Whether used for its buffering capacity or as a source of magnesium ions, it remains a staple in modern chemical synthesis. Its solubility and stability make it an ideal choice for liquid and solid formulations alike.
