Oiticica tree

Oiticia oil is a vegetable oil that is obtained from the seeds of Licania rigida , a South American tree from the golden plum family of the genus Licania . Cacahuananche oil (Mexican oiticia oil) from Licania arborea is related to this . It has similar properties to tung oil ; it is one of the semi-drying oils.

The triglycerides of the oil are mainly composed of esters with couepic acid (α-licanic acid), a branched-chain and tri-unsaturated keto fatty acid ( keto acid ). The oil is also very heavy with a density of approx. 0.97 kg / l, it is probably one of the heaviest oils, the isano oil (Boleko oil) is even heavier. In terms of gelatinization, it behaves similarly to tung oil. At room temperature it is yellowish and musky , after a while it crystallizes and becomes whitish, sebum-like . After brief heating, it becomes permanently liquid, in this form it is also known as "Cicoil".

Oiticia oil is used for lacquers, varnishes , inks and for the production of linoleum and factice . It can also be used to treat wood.
