    (Z)-alpha-Farnesol (CAS 82010-12-6) is a geometric-isomer sesquiterpene alcohol widely used in perfumery and cosmetics as a fragrance ingredient (floral, citrus, woody facets), odor modifier, mild fixative, and preservative booster due to antibacterial/antifungal activity (e.g., against Staphylococcus and Candida); it is incorporated into skin-care products, deodorants, shampoos, soaps, fine fragrances, and scented candles; serves as a solubilizer/co-emulsifier and penetration enhancer in certain formulations; functions as an intermediate for farnesyl esters, higher terpenoids, and isoprenoid pharmaceuticals; acts as a signaling probe in membrane and quorum-sensing studies; and is employed as a semiochemical/pheromone component in insect traps for integrated pest management; it is prone to oxidation and is typically stabilized with antioxidants and stored away from light, heat, and air.
