Mineral turpentine, also known as turpentine substitute, turps substitute, or just turps is an inexpensive petroleum-based replacement for the vegetable-based turpentine. It is commonly used as a paint thinner for thinning oil-based paint and cleaning brushes, and as an organic solvent in other applications.
Mineral turpentine is a hydrotreated light distillate of petroleum, and consists of a complex mixture of highly refined hydrocarbon distillates mainly in the C9-C16 range. The material is a clear transparent liquid at room temperature. The liquid is highly volatile and the vapours are flammable. It can be a very dangerous inhalant.
