Optional CAS 1009-62-7 / PERFUMING

A volatile aldehyde compound primarily utilized as a fragrance ingredient to impart fresh oceanic and marine scent profiles to cosmetic formulations. Also recognized by alternative names including Nor Majantal, Floralozone, and Aldehyde C-11, this aromatic compound serves a purely sensorial function in skincare products. Its inclusion enhances the overall user experience through olfactory appeal rather than providing direct skin benefits.
