( white gas). or mineral spirits (US, Canada), also known as mineral turpentine (AU/NZ), turpentine substitute, and petroleum spirits, is a petroleum-derived clear liquid used as a common organic solvent in painting. There are also terms for specific kinds of white spirit, including Stoddard solvent and solvent naphtha (petroleum). White spirit is often used as a paint thinner, or as a component thereof, though paint thinner is a broader category of solvent.

Types and grades

Three different types and three different grades of white spirit exist. The ''type'' refers to whether the solvent has been subjected to

used as the starting material and the conditions of distillation. In addition there is type 0, which is defined as distillation fraction with no further treatment, consisting predominantly of saturated C₉ to C₁₂ hydrocarbons with a boiling range of . Stoddard solvent is a specific mixture of hydrocarbons, typically over 65% C₁₀ or higher hydrocarbons, developed in 1924 by Atlanta dry cleaner W. J. Stoddard and Lloyd E. Jackson of the Mellon Institute of Industrial Research as a less flammable petroleum-based dry cleaning solvent than the petroleum solvents then in use. Dry cleaners began using the result of their work in 1928 and it soon became the predominant dry cleaning solvent in the United States, until the late 1950s. Turpentine substitute is generally not made to a standard and can have a wider range of components than products marketed as white spirit, which is made to a standard (in the UK, British Standard BS 245, in Germany,

51632). Turpentine substitute can be used for general cleaning but is not recommended for paint thinning as it may adversely affect drying times due to the less volatile components; while it may be used for brush cleaning its heavier components may leave an oily residue.

Physical properties

Type 1 white spirit is mainly used in most of Europe and Stoddard solvent is used in the US, both of which correspond to each other.

Use

Degreasing and lubricating

In industry, white spirit is used for cleaning and degreasing machine tools and parts, and in conjunction with cutting oil as a

. White spirit is commonly used for cutting fluid in ultraprecision lathes (commonly referred to as diamond turning machines). White spirit is used for regripping golf clubs. After the old grip is removed, the white spirit is poured into the new grip and shaken. After the white spirit is poured on, the new underlying tape and the new grip are slid on. After an hour of drying out, the new grip and club are ready to use.

Solvent and paint thinner

White Spirit is a petroleum distillate used as a paint thinner and mild solvent. White spirit is an inexpensive petroleum-based replacement for the vegetable-based turpentine. It is commonly used as a paint thinner for oil-based

and cleaning brushes, and as an organic solvent in other applications. Mineral turpentine is chemically very different from turpentine, which mainly consists of pinene, and it has inferior solvent properties. Artists use white spirit as an alternative to turpentine since it is less flammable and less toxic. Because of interactions with pigments in oil paints, artists require a higher grade of white spirit than many industrial users, including the complete absence of residual sulfur. White spirit was formerly an active ingredient in the laundry soap

, used to dissolve oils and grease in laundry stains, and as a popular remedy for eliminating the irritant oil urushiol in poison ivy. It was removed as a potential health risk. White spirit has a characteristic unpleasant kerosene-like odor. Chemical manufacturers have developed a low odor version of mineral turpentine which contains less of the highly volatile shorter hydrocarbons. Odorless mineral spirits is white spirit that has been further refined to remove the more toxic aromatic compounds, and is recommended for applications such as oil painting, where humans have close contact with the solvent.

Portable stoves

Although white spirit is used as an alternative to kerosene in portable stoves , this is not advisable as typical grades of white spirit have a lower flash point than kerosene. It cannot be used as an alternative to white gas, which is a much more volatile gasoline-like fuel.

Toxicity

White spirit is mainly classed as an irritant. It has a fairly low acute toxicity by inhalation of the vapour, dermal (touching the skin) and oral (ingestion) routes. However, acute exposure can lead to central nervous system depression resulting in lack of coordination and slowed reactions. Exposure to very high concentrations in enclosed spaces can lead to general

effects (drowsiness, dizziness, nausea, etc.) and can eventually lead to unconsciousness. Oral ingestion presents a high aspiration hazard. Prolonged or repeated skin exposure over a long period of time can result in severe irritant dermatitis, also called contact dermatitis. Continuous exposure to an average white spirit concentration of 240 mg/m³ (40 ppm) for more than 13 years can lead to chronic central nervous system effects. Similar long-term studies have been made in which some of the observed effects included memory impairment, poor concentration, increased irritability etc. White spirit is implicated in the development of chronic toxic encephalopathy (CTE) among house painters. In severe cases CTE may lead to disability and personality changes. These effects in painters were first studied in the 1970s in the Nordic countries. Owing to the volatility and low bioavailability of its constituents, white spirit, although it is moderately toxic to aquatic organisms, is unlikely to present significant hazards to the environment. It should not however, be purposely poured down the sink or freshwater drain. People can be exposed to Stoddard solvent in the workplace by breathing it in, swallowing it, skin contact, and eye contact. The Occupational Safety and Health Administration (OSHA) has set the legal limit ( Permissible exposure limit) for Stoddard solvent exposure in the workplace as 500 ppm (2900 mg/m³) over an 8-hour workday. The National Institute for Occupational Safety and Health (NIOSH) has set a Recommended exposure limit (REL) of 350 mg/m³ over an 8-hour workday and 1800 mg/m³ over 15 minutes. At levels of 20,000 mg/m³, Stoddard solvent is
