Stillingia oil

Stillingia oil is gained by solvent from the plant seeds of the Sapium family such as, Sapium sebiferum (Chinese tallow tree) and Sapium discolor (Mountain tallow tree). It is used as a drying agent in paints and varnishes. It dries readily on a glass plate in 4–6 hours. Stillingia oil's properties, such as a high iodine value, and chemical components classifies it as a drying oil. Why it has the appropriate properties to be a drying oil remain disputed. Following are three different arguments from J. Devine (1950), A. Crossley with T.P. Hilditch (1953), and V. C. Batterson with W. M. Potts (1938): Stillingia oil is gained by solvent from the plant seeds of the Sapium family such as, Sapium sebiferum (Chinese tallow tree) and Sapium discolor (Mountain tallow tree).

Following are three different arguments from J. Devine (1950), A. Crossley with T.P. Hilditch (1953), and V. C. Batterson with W. M. Potts (1938): Converging information include 25.4 to 40% linolenic acids, 25% to 51% linoleic acids, 10.4 to 22% oleic acids and 9% saturated acids. However J. Devine attributes the drying properties of stillingia oil to 2: 4-decadienoic acid (1950). However, A. Crossley with T.P. Hilditch point out that tripolyethenoid glycerides is the main component (1953), and V. C. Batterson with W. M. Potts(1938) came to conclusion that all of stillingia oil's properties add up to be good drying oil properties. Commercial stillingia oil has frequently been found to contain up to 1% of elaeostearic acid which can be also found in Sabium dicolor up to 1%. Tung oil has which is also a drying oil has 82.0% alpha-Eleostearic acid, so it is possible that factories containing both substances may end up with contamination.
