Safety
Safety Profile
Ethyl butyrate is recognized for its safety in food applications by the FDA. A RIFM assessment confirmed its non-genotoxic nature and indicated a low risk of skin sensitization, evidenced by a human maximization test at a concentration of 3450 μg/cm2. While specific CIR or SCCS opinions are not documented in the provided data, IFRA Amendment 51 permits its unrestricted use in cosmetic products (Category 4) under good manufacturing practices. Typical inclusion rates in skin creams range from approximately 0.2% to 1%, and up to 3% in deodorant sticks.
