Linseed oil unusually large amount of α-linolenic acid, which has a distinctive reaction with oxygen in air. Specifically, the fatty acids in a typical linseed oil are of the following types: Having a high content of di- and tri-unsaturated esters, linseed oil is particularly susceptible to polymerization reactions upon exposure to oxygen in air. This polymerization, which is called 'drying', results in the rigidification of the material. The drying process can be so exothermic as to pose a fire hazard under certain circumstances. To prevent premature drying, linseed oil-based products (oil paints, putty) should be stored in airtight containers. Like some other
Vateria indica oil Vateria indica oil "Vateria indica" oil is extracted from the seeds of the "Vateria indica" plant, a species in the Dipterocarpaceae family. The "Vateria indica" plant is indigenous to the Western Ghats, Kerala and Tamil Nadu regions of India. It thrives in the evergreen forests, surviving up to 800 meters above sea level. Oil from the seeds of the plant is extracted through a chemical refining process which makes the plant edible. Dhupa kernels are approximately 47% of the fruit, with the average kernel weighing 55 grams. The color of the kernel is reddish white or green, and it has
