White spirit (Low / High Aromatic Solvents) or generically, "paint thinner", is a petroleum-derived clear liquid used as a common organic solvent in painting.
A mixture of aliphatic and alicyclic C7 to C12 hydrocarbons, white spirit is insoluble in water and is used as an extraction solvent, as a cleaning solvent, as a degreasing solvent and as a solvent in aerosols, paints, wood preservatives, lacquers, varnishes, and asphalt products. About 60% of the total white spirit consumption is used in paints, lacquers and varnishes. White spirit is the most widely used solvent in the paint industry. In households, white spirit is commonly used to clean paint brushes after use, to clean auto parts and tools, as a starter fluid for charcoal grills, to remove adhesive residue from non-porous surfaces, and many other common tasks.
