Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) determined Magnesium Phosphate to be safe for use in cosmetics, with assessments indicating it was non-irritating to rabbit skin. However, some sources, such as EWG Skin Deep, note that CIR data for skin/eye/lung irritation may have an 'unknown/unassessed weight of evidence.' The ingredient is generally recognized as safe (GRAS) by the FDA for use as a nutrient supplement and pH control agent in food. A 2025 safety data sheet further states it is not considered hazardous by US OSHA Hazard Communication Standards, reporting no specific data on skin corrosion or irritation.
