  • Applications

    beta-Farnesene (CAS 77129-48-7) is a natural sesquiterpene used both as an active ingredient and a versatile intermediate: in agriculture it acts as an insect behavior modulator (mimicking the aphid alarm pheromone) to repel, disrupt, aid trapping, and support eco-friendly integrated pest management; in fragrance, flavor, and personal care it imparts green, woody, herbal facets that add diffusion and mild fixative character to perfumes, flavors, and consumer products; in bio-based chemistry, fermentation-derived beta-farnesene serves as a platform molecule that can be hydrogenated to farnesane for renewable fuel applications, oligomerized/hydrogenated to squalane and hemisqualane as emollients, gentle solvents, and carriers, and converted into specialty lubricants, surfactants, resins, and polymers; its biodegradability, favorable safety profile, and suitable volatility further support adoption in greener formulations and sustainable supply chains.
