Description
A light yellow, semidrying oil obtained from the seeds of sunflowers, Helianthus annus. Sunflower oil contains the following fatty acids: linoleic (63%), oleic (26%), palmitic (6%), stearic (5%) with traces of linolenic (<0.1%) (Learner 2005). It has a very low viscosity is primarily used for cooking. Sunflower oil has occasionally been mentioned as an additive to oil paints or varnishes. It is used industrially as an additive to alkyd paints.
