Regulatory information

The safety of 4-Hydroxy-2,5-dimethyl-3(2H)-furanone has been evaluated by the Research Institute for Fragrance Materials (RIFM), with a peer-reviewed safety assessment published. It was found to have the potential to cause skin sensitization in a small percentage of individuals. This means that, in a limited number of people, repeated contact at a sufficiently high level may cause a temporary reaction, including redness, rash or itching on the skin. To prevent sensitization, RIFM has established a maximum acceptable concentration level for this ingredient, and the International Fragrance Association (IFRA) has established safe standards for its use in home and personal care products.
