Sensitization risk Low

The Research Institute for Fragrance Materials (RIFM) has concluded that this ingredient poses no concern for genotoxicity, skin sensitization at current declared use levels, or phototoxicity/photoallergenicity. Human skin patch tests with a 3% solution showed no signs of irritation or sensitization. While the raw material is classified with hazard statements indicating skin irritation (H315, H316) and serious eye irritation (H319), these classifications typically apply to the concentrated raw form, not necessarily to diluted finished products. It is listed by the FDA as FEMA 2877, generally recognized as safe (GRAS) for use as a flavoring agent under 21 CFR 172.515.
