White spirit clear liquid derived from petroleum distillation that has many applications as organic solvents in various industries. This chemical is known as mineral spirit, varsol, Stoddard solvent, petroleum spirit, or generally paint thinner. It is insoluble in water with the boiling point of 140-220.
There are three different grades and types of this component based on the function of solvent for hydrodesulfurization, solvent extraction, and hydrogenation.
Each type also contains three grades, such as:
1) Low flash grade
2) Regular flash grade
3) High flash grade
This classification is determined by the crude oil as a starting material and the type of distillation.

Health effect and Toxicity
White spirit, mainly known as an irritant and its direct contact would lead to serious danger for the health of humans. Acute exposure can be risky to central nervous system depression.
Inhalation of vapors of this substance, contact with the skin and swallowing in the oral (swallowing) pathways has a relatively low toxicity.
