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

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 .

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.

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.

. 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.

, 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.

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 narcotic 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

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
