Magnesium Chloride
What is Magnesium Chloride?
Magnesium Chloride is an inorganic compound, chemically MgCl2, derived from evaporated seawater brines or mineral deposits. It appears as colorless crystals or flakes, highly soluble in water. In cosmetics, it belongs to the category of inorganic salts commonly found in cleansers, toners, lotions, shampoos, and bath products. Its primary function is as a viscosity controlling agent, where it modulates the thickness of formulations to enhance stability, improve suspension of particles, and optimize texture for better application and user experience. By influencing rheological properties, it ensures even dispensing and a smooth feel. Additionally, its mineral nature contributes to a mild soothing sensation in products inspired by seawater or mineral-rich sources like the Dead Sea.
