  • Applications

    Alpha-Acorenol (CAS 28296-85-7) is a sesquiterpene alcohol with a characteristic woody-earthy profile, used primarily in the fragrance industry to build and reinforce vetiver/smoky/amber facets, serving as a base-note fixative and odor modulator in fine fragrances, soaps, shampoos, cleaners, scented candles, and personal care; in formulation it is employed neat or via ester derivatives (e.g., acorenyl acetate) to improve odor longevity and compatibility while masking industrial background notes; in analytics and research, alpha-acorenol acts as a GC/MS reference standard for qualitative-quantitative profiling, a chemical marker for origin/authenticity and quality control of sesquiterpene-rich essential oils (notably vetiver, patchouli, cyperus), and as a substrate/reference in studies of sesquiterpene synthases and exploratory in vitro bioactivity (antimicrobial, antioxidant); it is also useful for fragrance stability screening, matrix-interaction studies in delivery systems, and sustainable fragrance supply optimization, with use subject to IFRA guidance and applicable cosmetic regulations.
