These oils have a rich buttery consistency with the same feel and performance of conventional oils. The difference is they may be thinned and cleaned with water. Due to their modern formulation, Max colors provide you with a permanent non-yellowing white. You can mix into these colors traditional oils in small amounts and still retain its "water friendliness." Mixing in a large amount of other oils would require the use of traditional solvents. Use with virtually any type of brush, with any oil medium, on any type of surface. Sacrifice nothing, and avoid dealing with caustic solvents! Max Oils are excellent for people with sensitive skin, those prone to rashes and for classroom use. Made in the USA.
