What are Water Soluble Oil Paints?First of all, it is important to understand what water soluble oil paints are. They are not water-based, but water-soluble paint and that distinction is key. These paints are real oils, they simply have the ability to be mixed and cleaned with water.
Water soluble means that you can use water to thin the oil paint (though traditional oil mediums like linseed or stand oils can also be used). While we learned in elementary school that water and oil do not mix, the water mixable (also called water miscible or solvent-free oils) paints have been formulated to accept water and get around that chemical barrier. http://painting.about.com/cs/oils/a/oilswatersol.htm
