Geraniol
What is Geraniol?
Geraniol is a pale yellow oily liquid alcohol with the molecular formula C10H18O, derived from plants such as geranium, rose, citronella, and lemon. This terpene alcohol delivers a sweet, rosy, citrus-like aroma. Primarily employed in perfumery and personal care formulations, it acts as a volatile scent contributor, blending with other notes to define a product's olfactory identity. It also neutralizes off-putting base odors through sensory masking. Available in natural extracts or synthetic forms for purity and consistency, geraniol integrates into shampoos, lotions, creams, and perfumes. Its slow evaporation ensures prolonged fragrance release on skin or hair, enhancing user appeal without altering product texture.
