Description
Ionone (CAS 8013-90-9), also known commercially as Ionon, Jonone, Iridon, Irisone, and Iraldeine, is a naturally derived fragrance and flavoring compound with a characteristic violet and woody odor profile. It occurs as a mixture of alpha and beta isomers and is classified under EC 232-396-8.
In personal care and cosmetics, ionone functions as a fragrance fixative and primary scent contributor in perfumes, soaps, and skin care formulations, where its violet-woody character provides depth and longevity to fragrance compositions. In food and nutrition applications, it serves as a flavoring agent, imparting berry and floral notes to confectionery, beverages, and dairy products at controlled concentrations.
Ionone is supplied in liquid form and is available in cosmetic and food-grade specifications compliant with REACH and IFRA guidelines. It is soluble in alcohol, mineral oil, and propylene glycol, making it compatible with standard fragrance and flavor carrier systems. Packaging formats typically include drums and intermediate bulk containers.
