VIII. Oil of Tsubaki 



The oil is prepared by pressing the seeds of the Thea japonica Nois. 

 The kernel which constitutes about 50% of the seed, contains 56.78% of 

 oil and 17% of water. On a manufacturing scale, the yield of the oil from the 

 seed is 28.3%. Under the Eleiden test, the oil solidifies after 3 hours. It is 

 non-drying and is used in a hair-dressing for women, also as machine 

 oil and table oil. It is also used in the preparation Turkey red oil. 



The physical and chemical constants of Tsubaki seed oil are as 

 follows : — 



Specific gravity 0.9159

IX. Sazanqua Oil 



The oil is obtained by pressing the seeds of the Thea sazanqua Nois. 

 The seed consists 23%, of husk and 67% of kernel; the latter contains
