VII. Styrax Oil 



The oil is prepared from the seeds of the Styrax japonica, S. et Z. 

 The kernel which constitutes about 40% of the weight of the seed contains 

 41.12% of oil and 4.58% of water. On a manufacturing scale, the oil is 

 produced up to 8.15% of the weight of the entire seed. It is a tasteless 

 and odourless oil of violet color and is hard to decolorize. Under the 

 Eleiden test, the oil remains liquid forming only a small amount of 

 coagulated substance. It is non-drying and is used as a lubricant of 

 inferior quality. 



The physical and chemical constants of Styrax oil are so follows: — 



Specific gravity 0.9341 



Solidifying point Below-23°C. 



Acid value 0.75 



Saponification value 185.1
