Linseed oil is a pale yellow oil extracted from the seeds of flax (linseed).
Linseed Oil hardens on exposure to air (it is a drying oil) because it contains linoleic acid and linolenic acid, and is used in enamels, oilpaints, putty, linoleum and varnishes.
Linseed oil is currently one of the highest known vegetable oils with the highest content of essential fatty acids (omega-3 and omega-6 fatty acids).

Linseed oil is distinctive for its unusually large amount of α-linolenic acid, which oxidises in air.
Having a high content of di- and tri-unsaturated esters, linseed oil is susceptible to polymerization reactions upon exposure to oxygen in air.
This polymerization, which is called autoxidation, results in the rigidification of the material.
To prevent premature drying, linseed oil-based products (oil paints, putty) are stored in airtight containers.
