  • Applications

    6-Methyl citronellol (CAS 25905-16-2) is primarily used as a fragrance ingredient in perfumery and cosmetics; it may also serve as an aroma component in household and cleaning products, contributing a floral citrus note. It can function as an intermediate in the synthesis of other fragrance compounds, and may be evaluated for flavor/aroma applications in foods under regulatory constraints. Additionally, it can be used as a fragrance additive in polymers/plastics or packaging to impart a scent, with use governed by local regulations.
