Mineral turpentine
Encyclopedia
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 colorless transparent liquid
at room temperature
, and immiscible to water. The liquid is highly volatile and the vapours are flammable. It can be a very dangerous inhalant
.
Mineral turpentine has a characteristic unpleasant odor. Chemical manufacturers have developed a low odor version of mineral turpentine which contains less of the highly volatile shorter hydrocarbons.
Petroleum
Petroleum or crude oil is a naturally occurring, flammable liquid consisting of a complex mixture of hydrocarbons of various molecular weights and other liquid organic compounds, that are found in geologic formations beneath the Earth's surface. Petroleum is recovered mostly through oil drilling...

Paint thinner
A paint thinner is a solvent used to thin oil-based paints or clean up after their use, although all such solvents have other uses. Commercially, "paint thinner" is usually a name for mineral spirits.Products used as paint thinners include:*Mineral spirits...

Liquid
Liquid is one of the three classical states of matter . Like a gas, a liquid is able to flow and take the shape of a container. Some liquids resist compression, while others can be compressed. Unlike a gas, a liquid does not disperse to fill every space of a container, and maintains a fairly...
