Any residue of this surfactant loses its effectiveness when the oil color is dry, and has no effect in the drying process. The paint is water soluble, but the oil is identical to that used in Holbein Artist Oil Color. If the artist does not wish to use water, Duo can be used as a traditional oil color.There is no water in the product, only a surfactant which covers the pigment and oil, making both water sensitive or soluble.
