The literature abounds with information covering the investigation of linseed oil and other vegetable oils. However, very little work has been reported covering the minor ingredients of linseed oil or their effect upon the drying properties have been affected out of the range of what would be indicated by iodine values, and it has been suspected that there is some small quantity of material present in the oil that acts as an oxygen inhibitor, delaying gelation. Among the minor ingredients of linseed oil suspected of inducing this desultory reaction is the unsaponifiable fraction of the oil. It is the purpose of this investigation to determine the actual effect of the unsaponifiable material and sterols upon the drying characteristics of raw linseed oil.
