Magnesium Chloride

Magnesium Chloride Hexahydrate is a highly bioavailable form of magnesium salt harvested from ancient seabeds or extracted from seawater, containing six water molecules per magnesium chloride unit. The crystalline flake form is particularly valued in cosmetics and bath products because it dissolves rapidly and completely in water, delivering magnesium ions that can be absorbed transdermally through the skin. Formulators choose this hexahydrate variant over anhydrous magnesium chloride because it's less hygroscopic, easier to handle, and provides a more stable, consistent concentration of magnesium in formulations.
