Farnesyl Acetate
What is Farnesyl Acetate?
Farnesyl acetate is the acetic acid ester of farnesol, a naturally occurring sesquiterpene alcohol found in essential oils from plants like citronella and palmarosa. Chemically, it is a (2E,6E)-3,7,11-trimethyldodeca-2,6,10-trien-1-yl acetate, appearing as a clear, colorless to pale yellow liquid with a mild, green-floral, fruity odor profile. In cosmetics, it belongs to the fragrance ingredient category, primarily employed in perfumes, lotions, and toners. It functions by slowly volatilizing to release its characteristic scent, helping shape the product's overall aroma while masking less desirable base notes. Additionally, it contributes a tonic-like quality, delivering a light, refreshing after-feel through mild astringency and solvent properties, enhancing the sensory application experience without heavy residue.
