MINERAL TURPENTINE OIL

Three different types and three different grades of white spirit exist. The type refers to whether the solvent has been subjected to  hydrodesulfurization  (removal of sulfur) alone (type 1), solvent extraction (type 2) or  hydrogenation  (type 3).


Each type comprises three grades: low flash grade, regular grade, and high flash grade (flash refers to flash point). The grade is determined by the  crude oil 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 C 9  to C 12  hydrocarbons with a boiling range of 140–200 °C (284–392 °F).


Stoddard solvent  is a specific mixture of hydrocarbons, typically over 65% C 10  or higher hydrocarbons, [4]  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. [5][6]  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,  DIN  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.


In Australia, white spirit is normally sold under the generic name of Shellite (a trademark of Shell Australia), and is composed of C 6  to C 10  straight alkanes, classing it as light pure  naphtha . It is used for fuel and cleaning.

White Spirit is a  petroleum distillate  used as a  paint thinner  and mild  solvent . In industry, mineral spirits are used for cleaning and  degreasing  machine tools and parts, and in conjunction with  cutting oil  as a  thread cutting  and  reaming   lubricant .

Mineral spirits are an inexpensive  petroleum -based replacement for the  vegetable -based  turpentine . It is commonly used as a paint thinner for oil-based  paint 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. [8] [ not in citation given ]  Artists use mineral spirits 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 mineral spirits than many industrial users, including the complete absence of residual sulfur.

Mineral spirits were formerly an active ingredient in the laundry soap  Fels Naptha , used to dissolve oils and grease in laundry stains, and as a popular remedy for eliminating the contagious oil  urushiol  in  poison ivy . It was removed as a potential health risk.
Mineral spirits have 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 are mineral spirits that have been further refined to remove the more toxic  aromatic compounds , and are recommended for applications such as oil painting, where humans have close contact with the solvent.

In  screen printing  (also referred to as silk-screening), mineral spirits are often used to clean and unclog screens after printing with oil-based textile and  plastisol inks. They are also used to thin inks used in making  monoprints .
Mineral spirits are often used inside  liquid-filled compasses  and  gauges .
Mineral spirits are used for regripping golf clubs. After the old grip is removed, the mineral spirits are poured into the new grip and shaken. After the mineral spirits are 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.

Although not normally marketed as a fuel, white spirit can be used as an alternative to kerosene in  portable stoves , since it is merely a light grade of kerosene. It cannot be used as an alternative to  white gas , which is a much more volatile gasoline-like fuel.
White spirits are a major ingredient in some popular automotive fuel/oil additives, such as  Marvel Mystery Oil , as they are capable of dissolving varnish and sludge buildup.

Mineral spirits are commonly used for cutting fluid in ultraprecision lathes (commonly referred to as  diamond turning  machines)
