We strongly recommend Gamsol to all oil painters, regardless of what brand of paint they choose. Unlike many thinners and solvents marked "odorless," Gamsol genuinely doesn't smell. It's less flammable than turpentine and safer to use. You can use it for:

  • Thinning oil colors. A little goes a long way; stiff oil colors relax immediately when a little Gamsol is added. Be careful not to thin oil colors too much with solvent alone, this can compromise the ability of the paint to form a paint film.
  • Modifying painting mediums. Gamblin's Galkyd line of painting mediums are made with Gamsol, so they readily accept Gamsol as a thinning agent. It also works in combination with linseed and other oils for traditional oil painting techniques. Note: Gamsol should not be added to painting mediums made with natural resins (dammar, copal, mastic). Turpentine should be used instead with these mediums.
  • Studio clean-up: Gamsol readily cleans brushes, palettes, and palette knives.

How does Gamsol achieve this level of performance and safety? Most solvents available to artists come from the industrial paint industry where solvent power and cheapness is prized. Gamsol is special: it is made for products and processes that come into more intimate contact with the body such as cosmetics, hand cleaners, and cleaning food service equipment.

Gamsol is a petroleum distillate, but virtually all the aromatic solvents have been refined out of it; less than .005% remain. Aromatic solvents are the most harmful types of petroleum solvents. The Gamsol SDS shows that it has an Exposure Limit Value higher than most solvents available to artists. In addition, Gamsol’s flash point allows it to ship via air cargo as a non-hazardous material. All of these factors have led to Gamsol being used widely in oil painting classrooms. In those classes, there are no solvent odors, only the wonderful smell of oil colors.

Available in 125 mL, 500 mL, 1 L, and 3.76 L (one gallon) sizes. Made in Oregon.
