Science
Mechanism of Action
In skincare, Magnesium Hydrogen Phosphate functions as a bioavailable source of magnesium and phosphate ions. Magnesium is a fundamental mineral involved in over 300 enzymatic reactions. While direct topical clinical studies for this specific compound are limited, research on magnesium ions (e.g., from magnesium chloride) suggests they can modulate epidermal differentiation and promote cell migration, potentially supporting early wound healing processes. Additionally, it expertly regulates and stabilizes the pH of cosmetic formulations.

Stability
Magnesium Hydrogen Phosphate is an odorless, white to off-white crystalline powder, demonstrating good stability under normal conditions. It decomposes above 500°C due to the evaporation of its inherent water, rather than exhibiting a distinct melting point. Optimal storage requires a dry environment. In aqueous solutions (100 g/l at 20°C), its pH typically ranges between 6.0 and 8.0.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Magnesium Hydrogen Phosphate is safe for use in cosmetics under current practices and concentrations, provided the final formulation is non-irritating. The U.S. FDA also recognizes it as Generally Recognized As Safe (GRAS) for direct human consumption in food.
