Description
α-Isophorone (CAS 78-59-1, EC 201-126-0), also known as Isophoron, Isoforone, Izoforon, and listed under FEMA 3553, is a cyclic ketone derived from acetone condensation. It carries no E-code designation. The compound is commercially available under several regional spelling variants across European and global markets.
In food and flavour applications, α-Isophorone functions as a flavorant at trace concentrations, contributing green, herbal, and peppery nuances to finished products. In personal care formulations, it acts as a skin conditioner and fragrance ingredient, where its moderate volatility supports controlled scent release and carrier functionality within complex fragrance blends.
α-Isophorone is supplied in liquid form meeting FEMA and REACH compliance requirements. Procurement teams should confirm supplier documentation against relevant food-grade or cosmetic-grade specifications prior to use. Standard packaging formats for B2B supply typically include drums and intermediate bulk containers, with HS code 29142990 applicable for EU customs classification.
