Whereas d-borneol was the
enantiomer that used to be the most readily available commercially, the more commercially available enantiomer now is l-borneol, which also occurs in nature.
Laevo-borneol is used in perfumery. It has a balsamic odour type with pine, woody and camphoraceous facets.
Toxicology
Borneol may cause eye, skin, and respiratory irritation; it is harmful if swallowed.[10] Acute exposure may cause headache, nausea, vomiting, dizziness, lightheadedness, and syncope. Exposure to higher levels or over a longer period of time may cause restlessness, difficulty concentrating, irritability, and seizures.[11]
Skin irritation
Borneol has been shown to have little to no irritation effect when applied to the human skin at doses used in fine fragrance formulation.[12] Skin exposure can lead to sensitization and a future
allergic reaction even to small quantities.[11]
Derivatives
The bornyl group is a univalent radical C10H17 derived from borneol by removal of hydroxyl and is also known as 2-bornyl.[13] Isobornyl is the univalent radical C10H17 that is derived from isoborneol.[14] The
structural isomerfenchol is also a widely used compound derived from certain
essential oils.

From p. 834: "Je donne, par cette raison, à l'hydrogène carboné de l'essence de valériane, le nom de bornéène, et, au camphre lui-même, celui de bornéol." (I give, for this reason [namely, that the compound that Gerhardt had obtained from valerian oil was identical to that obtained by Pelouze from camphor from Borneo], to the hydrocarbon from valerian essence, the name bornéène, and, to camphor itself, that of borneol.)
