D 1.505–1.517; phenols content: min. 52%.
Evergreen bay trees or bay-rum trees, which are up to 12m high, grow wild
and are also cultivated in northern South America and in the West Indies. The
main cultivation area is the island of Dominica where with ～20 t/yr, 85% of the
worldwide demand are produced.
Themajor components of the oil aremyrcene (20–30%), eugenol (42–56%), and
chavicol (8–13%).The phenol content is determined largely by the last
two compounds.
Bay oil has antiseptic properties because of its high phenol content and is, therefore,
a classical ingredient for perfuming after-shave lotions.
