Safety
Safety Profile
Generally recognized as safe (GRAS) by FEMA for food use. Human experience tests with a 2% solution indicated no irritation or sensitization. The IFRA Code of Practice recommends usage levels up to 10% in fragrance concentrates. While some safety data sheets have historically indicated skin and eye irritation, a significant majority (>99.9%) of recent reports state it does not meet GHS hazard criteria.
