Walnut oil

[1][2][3] According to gas chromatographic and HPLC analysis, virgin walnut oil consists of linoleic acid (60–62%).

[1] Walnuts typically contain high concentrations of phenolics including ellagic acid.

Its short drying time and lack of yellow tint make it a good oil paint base thinner and brush cleaner.

Some woodworkers favour walnut oil as a finish for implements that will come in contact with food, such as wooden bowls, because of its safety.

Rancidity is not an issue because walnut oil dries when applied to wood in a thin coating.
