In the competitive landscape of natural fragrance ingredients, essential oils, and functional personal care, (-)-β-trans-bergamotene (also known as trans-β-bergamotene, exo-β-bergamotene, or simply β-trans-bergamotene, CAS 15438-94-5) stands out as a versatile sesquiterpene with a captivating profile. Widely distributed in plant essential oils, bergamotene isomers—particularly α-trans-bergamotene as the most abundant in nature—share structural similarities, differing mainly in double bond positions. The β-trans isomer, however, offers a distinctive sweet, citrus-like fragrance with subtle woody and herbal nuances, evoking fresh bergamot orange zest blended with light spicy warmth.
This elegant, uplifting scent makes (-)-β-trans-bergamotene a prized addition to perfumes, essential oil blends, food flavorings, and skincare formulations, where it enriches sensory experiences with bright, natural citrus depth and pleasant persistence.
The Aromatic Profile and Key Applications of β-Trans-Bergamotene
Renowned for its sweet citrus character—reminiscent of bergamot's fruity freshness with mild herbal and woody undertones—(-)-β-trans-bergamotene imparts vibrancy and complexity:
- In flavors & fragrances: Enhances citrus, woody, and spicy accords in fine perfumery and aroma compounds; adds uplifting top-to-middle notes in modern colognes, fresh fougères, or natural-inspired scents.
- In personal care & cosmetics: Ideal for skincare products, lotions, soaps, and body care—delivering a clean, invigorating aroma that elevates everyday formulations.
- In mosquito repellent sprays & insect-repellent products: Exhibits notable repellent properties against mosquitoes and insects; serves as a natural, bio-based active in functional formulations for outdoor protection, leveraging its role in plant-insect interactions (including pheromone-like effects in some species).
With its molecular formula C₁₅H₂₄ and high ≥98% purity, this sesquiterpene ensures clean performance, minimal impurities, and consistent bioactivity—outperforming many naturally extracted alternatives.
Overcoming Traditional Extraction Challenges: Microbial Fermentation Innovation
Conventional sourcing relies on physical extraction from essential oils of plants like citrus, pepper, or basil, where bergamotene occurs in trace amounts amid complex mixtures. This results in low yields, high costs, seasonal variability, and purification difficulties.
