Product Description
                                                                                                                                                                                                                                                                                                                                
Food Grade Magnesium Hydroxide Powder is produced via controlled precipitation from high-purity magnesium salts, followed by filtration, washing, drying, and fine milling. The resulting powder features ultra-fine, uniform particles, high magnesium hydroxide content (≥99%), and minimal impurities, making it fully compliant with food safety regulations.
The powder exhibits low moisture content (<0.5%), high specific surface area (50–100 m²/g), and adjustable particle size (D50 2–10 μm), allowing controlled solubility and functional performance in liquid and solid food systems. Its dense yet free-flowing nature ensures efficient handling, accurate dosing, and long-term storage stability.
Food Grade Magnesium Hydroxide Powder is widely used in functional foods, fortified beverages, antacids, and nutritional supplements, and it also serves as a precursor for magnesium oxide production, pH regulator, and neutralizing agent in food applications.
