Expert Verdict
Very low concern. EWG rating of 1 (lowest hazard). Non-toxic, water-soluble salt with no documented sensitization or irritation issues at cosmetic-use concentrations. Magnesium salt of acetic acid; EC No. 205-554-9; highly water-soluble; stable and compatible with strong oxidizing agents should be avoided; synthetic origin
