Linseed oil alkaline) which promotes hardening (polymerisation) of linseed oil by reaction with atmospheric oxygen. Heating shortens its drying time. Raw linseed oil is the base oil, unprocessed and without driers or thinners. It is mostly used as a feedstock for making a boiled oil. It does not cure sufficiently well or quickly to be regarded as a drying oil. Raw linseed is sometimes used for oiling cricket bats to increase surface friction for better ball control.

Jojoba oil and climate in which the plant is grown, as well as when it is harvested and how the oil is processed. In general it contains a high proportion of mono-unsaturated fatty acids, primarily 11-Eicosenoic acid (Gondoic acid). Being derived from a plant that is slow growing and difficult to cultivate, jojoba oil is mainly used for small-scale applications such as pharmaceutical and cosmetics. Overall, it is used as a replacement for whale oil and its derivatives, such as cetyl alcohol. The ban on importing whale oil to the U.S. in 1971 led to the discovery that jojoba oil is "in
