 Meadowfoam seed oil is extraordinarily stable, primarily because it contains over 98% long chain fatty acids.. Meadowfoam oil is most similar to rapeseed oil, with which it competes directly for the high-volume industrial oilseed applications.Meadowfoam oil is widely used in cosmetic and hair-care applications due to its stability, emolliency and smooth, soft skin feel.The oil in its unpurified form is not suitable for human consumption, primarily because of its erucic acid content.
