Oiticica oil
Oiticica oil is a light-yellowish oil obtained from the seeds of oiticica tree (Microdesmia rigida ) which grows mainly in Brazil.[2]
Extraction and appearance
[edit ]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.[3]
Usage
[edit ]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.[3] [4]
Composition
[edit ]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%).[2] [3]
