Holbein Duo Aqua Paint
There has always existed the need for an oil color for the professional and for the student with all the handling qualities and characteristics of a true oil color, but without the negatives of the traditional medium.
The production of a water soluble oil color has been solved by different manufacturers in different ways, though not all seem to have the qualities of true oil color. Holbein’s objective in formulating DUO Aqua Oil Color was production of a genuine oil color for the professional, with the same qualities and characteristics of the traditional Holbein Artist Oil Color, certainly one of the world’s finest.
To make DUO identical in every respect to its traditional professional grade cousin, Holbein developed a unique additive which works as a surfactant, any residue of which loses its effectiveness once the oil color is dry.
DUO Aqua Oil Color is water soluble, but the oil is identical to that used in Holbein Artist Oil Color. There is no special treatment. There is no modification or breaking down (cracking) of the oil. There is no water in the product, only the additive that is rendered redundant and of no effect in the drying process.
The surface agent covers the pigments and oil, this making both water sensitive or soluble. That is all. There is no other ingredient present.
