Description
α-Ionone (CAS 127-41-3) is a naturally occurring ketone found in violet flowers and certain fruits, commercially identified under FEMA 2594 and also referenced as (5E)-Ionone or Alpha-Jonone. It carries no E-code designation. REACH registration applies within the EU under EC number 204-841-6.
In fragrance formulation, α-Ionone delivers a woody, violet-like character and is used at low concentrations to anchor floral top notes in fine perfumery and personal care products. In food and beverage applications, it functions as a flavoring agent under FEMA 2594, contributing berry and fruity nuances to confectionery and dairy products.
α-Ionone is supplied as a clear yellow oil in fragrance and food-grade specifications, with compliance available against FCC standards for food applications and REACH requirements for industrial use. Typical packaging includes drums and intermediate bulk containers. Buyers should confirm grade suitability against their specific regulatory framework prior to procurement.
