Non-drying oil

A non-drying oil is an oil which does not harden and remains liquid when it is exposed to air. This is as opposed to a drying oil, which hardens completely, or a semi-drying oil, which partially hardens. Oils with an iodine number of less than 115 are considered non-drying.

Uses

Non-drying oil is often used as a base in anti-climb paint, a type of slippery coating used to prevent climbing on its surface. Another use would be in baby oil.
