Borneol

What is Borneol?

Borneol is a bicyclic monoterpene alcohol, chemically known as 1,7,7-trimethylbicyclo[2.2.1]heptan-2-ol, naturally extracted from essential oils of plants like the Borneo camphor tree (Dryobalanops aromatica), rosemary, thyme, and cinnamon. It exists as colorless crystals or powder with a characteristic sharp, camphoraceous, and slightly minty aroma. In cosmetics, it falls under fragrance ingredients, typically incorporated into personal care products such as creams, lotions, shampoos, and perfumes at trace levels. It functions by evaporating slowly to deliver persistent woody-spicy sensory notes, enhancing the overall scent profile. As a masking agent, it overlays and neutralizes off-odors from base formulation components, improving user experience without altering product texture or stability.
