Safflower oil

As linseed oil shows a certain yellowing in time, some artists prefer to replace it with safflower oil, particularly for white paint. Safflower oil is pressed from the seed of the safflower thistle. This oil turns less yellow than linseed oil, but also has some disadvantages; the drying time is longer and the oil forms a film with other properties than those of linseed oil. As a result of these other properties, the use of white paint based on safflower oil in a painting that is built up of various layers (whereby it forms the undercoat for colours based on linseed oil) can cause the subsequent layers to crack or even to be unable to adhere properly. It is therefore advisable to limit the use of white paint based on safflower oil until the final phase of the painting.
