Farnesol
Farnesol is a natural terpene alcohol with a sweet floral and woody aroma, widely used in perfumes, cosmetics, and personal care products. It is primarily extracted from the essential oils of plants such as rose, orange blossom, and lemongrass, and is a core ingredient in many plant fragrances. Due to its excellent aroma properties and bioactivities such as antibacterial and antioxidant effects, farnesol has become an indispensable ingredient in the fragrance and cosmetics industry.
Farnesol exhibits good stability and fragrance longevity, therefore it is often used in middle and base notes, especially in floral and woody perfumes, where it adds rich layers of complexity. Furthermore, the application of farnesol in skin care products is gradually increasing, as its natural antioxidant and anti-inflammatory properties provide a soothing effect for sensitive skin.
