Pinene
What is Pinene?
Pinene encompasses alpha-pinene and beta-pinene, bicyclic monoterpene hydrocarbons abundant in essential oils extracted from coniferous trees like pine (Pinus spp.), as well as in rosemary, eucalyptus, and juniper. These colorless, volatile compounds feature a characteristic bridged-ring structure with exocyclic double bonds, enabling their strong piney, resinous aroma. In cosmetics, pinene belongs to the perfuming category, where it serves to define scent profiles in products such as lotions, shampoos, soaps, and perfumes. It functions by volatilizing at room temperature to release fragrance notes, blending with other aroma chemicals to enhance olfactory balance and mask base odors. Valued for its botanical origin, pinene supports natural fragrance formulations while adhering to regulatory scent usage standards.
