Oakmoss absolute is available in IFRA (International Fragrance Association) compliant and noncompliant versions. IFRA-compliant oils contain less than 100 ppm of atranol and chloroatranol, reducing the risk of skin irritation. However, a few suppliers sell noncompliant versions because they have a more mossy aroma that's preferred by many perfumers, according to Camden-Grey Essential Oils.
