Regulatory information
The safety of methyl ionone (isomer blend) has been evaluated by the Research Institute for Fragrance Materials (RIFM), and a peer-reviewed safety assessment has been published. This ingredient may 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 can 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 issued a safe-use standard for home and personal care products based on that level. Additional safety assessments of the ingredient have been conducted by various regulatory bodies worldwide.
