The safety of octahydro-7-methyl-1,4-methanonaphtalen-6(2H)-one has been evaluated by the Research Institute for Fragrance Materials (RIFM), and a peer-reviewed safety assessment has been 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 skin redness, rash or itching.
To prevent sensitization, RIFM has established a maximum acceptable concentration level for this ingredient in home products, air care products, cosmetics and personal care products. Although an ingredient may have the potential to cause skin sensitization, most people will not be affected. Every person's skin is different, so consult a healthcare professional with any questions you have.
