Monographs of fragrance chemicals and extracts that have caused contact allergy / allergic contact dermatitis

beta-Pinene is a colorless clear liquid; its odor type is herbal and its odor at 10% is described as ‘cooling, woody, piney and turpentine-like with a fresh minty, eucalyptus and camphoraceous note with a spicy peppery and nutmeg nuance’ (www.thegoodscentscompany.com). It is used as a chemical intermediate for the production of other fragrances such as myrcene (the starting material for acyclic terpenes), geraniol and linalool. Other uses include or have included as monomer for polyterpene resins, the production of hot melt adhesives, substitute for alpha-pinene, and flavoring agent for ice cream, candy and baked goods (U.S. National Library of Medicine).

Friedrich Wöhler (1800–1882) investigated the fate of turpentine oil in the human body. He concluded that internal and external use of this oil, as well as the inhalation of its vapour, quickly confers urine an odour reminiscent of violets. However, the addition of turpentine oil to urine does not produce a violet scent (Wöhler 1824). This indicates that metabolic conversion of turpentine oil components is necessary to attain a violet-like smell. The most widespread constituents in the oil of turpentine are bicyclic monoterpenes specifically alpha- and beta-pinene, followed by carene, camphene, and limonene, and trace amounts of many other compounds (Vespermann et al. 2017; Al-Tel et al. 2020). Indeed, α-pinene and β-pinene are the main odorous components released by various plant species (Mercier et al. 2009).
