COPAIBA OIL Chemical Properties,Usage,Production

Chemical Properties

Copaiba (balsam) oils are obtained by steam distillation of the exudates (balsam) from the trunks of several species of Copaifera L. (Caesalpiniaceae), a genus of trees growing in the Amazon basin where some 10 t of balsam are collected annually. Suitable species are Copaifera officinalis (Jacq.) L., Copaifera langsdorffii Desf., Copaifera multijuga Hayne, and so on. They are colorless to light yellow liquidswith the characteristic odor of the corresponding balsams and an aromatic, slightly bitter, pungent taste.
d²⁵₂₅ 0.880–0.907; n²⁰_D 1.4930–1.5000; α²⁰_D ?33 ° to ?7 °; solubility: 1 vol in 5–10 vol of 95% ethanol.
The oils consist primarily of sesquiterpene hydrocarbons; their main component is caryophyllene (>50%). Copaiba balsam oils and balsams are used mainly as fixatives in soap perfumes.
