Water miscible oil paint
Water miscible oil paint (also called "water
soluble") is a modern variety of oil
paint which is engineered
to be thinned and cleaned up with water, rather than having to use
chemicals such as turpentine. It can be mixed and applied using
the same techniques as traditional oil-based paint, but while still
wet it can be effectively removed from brushes, palettes, and rags
with ordinary soap and water. This eliminates the need for strong-smelling
and toxic solvents such as turpentine or turpentine substitute.
Its water solubility comes from the use of an oil medium in which
one end of the molecule has been altered to bind loosely to water
molecules, as in a solution.
There are several manufacturers producing water
miscible oil paint, including:
Grumbacher -- "Max Artists' Oil Colors",
produced using alkali-refined linseed oil or sunflower oils.
HK Holbein -- "Duo Aqua Oil", produced using an activator
which alters the structure of the linseed oil.
Royal Talens -- "Van Gogh H2Oil", produced using a quick-drying,
odorless vegetable oil.
Winsor & Newton -- "Artisan Water Mixable Oil Color",
produced using modified linseed and safflower oil.
The Royal Talens and Holbein paints do not use the traditional pigments
that are based on cadmium and other heavy metals, which further
reduces the toxicity risks of working with them.
