7-HYDROXY-3,7-DIMETHYL-OCTANAL/INDOLE.

Optional CAS 68908-82-7 / PERFUMING

A synthetic fragrance compound known as Indolene that combines hydroxycitronellal with indole to create a stable jasmine-like scent profile. This Schiff base molecule serves purely as a perfuming agent in cosmetic formulations, offering no therapeutic benefits for skin health. It provides controlled floral indolic notes while maintaining better stability than pure indole.
