Bay Oil. Steam distillation of the leaves of the tree Pimenta racemosa (Mill) which is indigenous to certain islands of the West Indies, particularly Dominica and Puerto Rico, is called bay or bay leaf oil. The same source was used in the past to produce Bay Rum in which mm was distilled over the leaves. Bay oil [8006-78-8] is a yellowish to dark brown mobile Hquid with a fresh-spicy, sometimes medicinal odor with a lasting sweet-balsamic undertone. The oil finds extensive use in hair tonics, after-shave lotions as well as other men s-type fragrances. There is Htde or no use by the flavor industry. The range of components for a number of bay leaf oils is shown in Table 25 (66). 

Pimento Berry Oil. The pimento or allspice tree, Pimenta dioca L. (syn. P. officinalis, Liadl.), a native of the West Indies and Central America, yields two essential oils of commercial importance pimento berry oil and pimenta leaf oil. The leaf oil finds some use ia perfumery for its resemblance to clove leaf and cinnamon leaf oils as a result of its high content of eugenol. Pimento berry oil is an item of commerce with extensive appHcation by the flavor industry ia food products such as meat sauces, sausages, and pickles, and moderate use ia perfumery, where it is used primarily as a modifier ia the modem spicy types of men s fragrances. The oil is steam-distilled from dried, cmshed, fully grown but unripe fmits. It is a pale yellow Hquid with a warm-spicy, sweet odor with a fresh, clean topnote, a tenacious, sweet-balsamic-spicy body, and a tea-like undertone. A comparative analysis of the headspace volatiles of ripe pimento berries and a commercial oil has been performed and differences are shown ia Table 52 (95).

Bay oil is obtained by steam distillation of the leaves of Pimenta racemosa (Miller) Moore (Myrtaceae). It is a dark brown liquid with a strong, spicy, clovelike odor. 

Pimento oils (allspice oil) are derived from pimento fruits and leaves. Pimento berry oil is obtained by steam distillation of the dried, fully grown, unripe, berrylike fruits of the pimento shrub, Pimenta dioica (L.) Merrill. (Myrtaceae), growing in the islands of the West Indies and Central America. It is a pale yellow to brown liquid with a spicy odor, reminiscent of eugenol.
