Safety
Safety Profile
Studies in animals indicated very low dermal absorption and no metabolic breakdown into potentially harmful compounds. While generally considered safe for cosmetic application, it is described as a mild eye irritant and may cause skin irritation in sensitive individuals. No evidence of increased cancer risk was observed in long-term feeding studies. EU regulations (2020/2081) specifically limit its concentration to 0.1% by weight in tattoo inks and permanent makeup.
