Magnesium Hydroxide is a food-grade mild alkaline compound used as an antacid, acidity regulator, colour retention agent and magnesium source in food and pharmaceutical applications.We supply bulk Magnesium Hydroxide sourced from leading China manufacturers, available in powder form for food and beverage manufacturers worldwide. Our Magnesium Hydroxide is widely used in pharmaceutical antacid, food processing, canned vegetables, sugar refining aid and wastewater neutralisation.
Magnesium Hydroxide (Mg(OH)₂) is produced by hydrating magnesium oxide or precipitating from seawater/brine. It is a mild base (pH ~10.5 in suspension) making it gentler than calcium hydroxide for food pH adjustment.
Used as an antacid (milk of magnesia), acidity regulator, colour retention agent in vegetables, and processing aid in sugar refining. Its buffering capacity prevents over-alkalisation in food systems.
