Oiticica oil is a light-yellowish oil obtained from the seeds of oiticica tree (Microdesmia rigida) which grows mainly in Brazil.
Extraction and appearance
Oiticica oil is generally obtained from the kernels by crushing, pressing and expelling at high temperatures (210-220 °C) to prevent its polymerization. The raw oil is yellowish, turning brown after oxidation. It has also an unpleasant smell and taste, which limits its use in food and cosmetics applications.
Usage
Oiticica oil is used in industrial oil paints and varnishes as a substitute for tung oil, either alone or mixed with linseed oil and sesame oil to achieve even better results.
Composition
The fat components of oiticica oil are polyunsaturated α-licanic acid (46 – 78% of total), saturated fat mainly palmitic and stearic acids (together, 11%), monounsaturated as oleic acid (4 – 12%).
