THE STORY OF MAGNESIUM OXIDE LIGHT
Magnesium Oxide Light: The Ultra-Fine Mineral for Absorption, Opacity & Skin Protection
Magnesium Oxide Light is a highly porous, ultra-fine grade of magnesium oxide known for its excellent absorbent, whitening, and protective properties.
It is widely used in cosmetics, pharmaceuticals, and personal care for its ability to control moisture, add opacity, and stabilize formulations.
Common uses include powders, creams, sunscreens, deodorants, toothpaste, and pharmaceutical preparations.
Produced from High-Purity Magnesium Salts via Calcination & Specialized Light Processing
Magnesium Oxide Light is produced by:
• Calcining magnesium carbonate or magnesium hydroxide at high temperatures
• Controlled milling to produce light, fluffy, low-density powder
• Purification to remove impurities
This process results in a high-surface-area mineral with excellent absorbency and whiteness.
TRCkem provides cosmetic- and pharma-grade Magnesium Oxide Light with controlled fineness.
