5-METHYLFURANONE is a cosmetic ingredient used in product formulation. Exercise caution due to limited available safety data.
5-Methylfuranone (also called 5-methylfuran-2(3H)-one, FEMA 3304, or gamma-methyl-gamma-butyrolactone) is a five-membered cyclic ester with a methyl substituent. It has a characteristic warm, caramel, buttery, sometimes pineapple-like aroma. Gamma-lactones of this size are small enough to be volatile yet stable enough for cosmetic fragrance use. The compound is not restricted under EU Regulation (EC) No 1223/2009 Annexes II or III, and has FEMA GRAS status for food use, supporting its safety in cosmetics. Natural occurrence in many edible plants and fruits provides additional assurance.
