In local communities, the economic exploitation of Bombacopsis retusa is made by using the fixed oil from seeds to produce soap.
The fixed oil of Bombacopsis retusa seeds had its fatty composition characterized by gas chromatography with flame ionization detection (GC-FID).
The melting point of a fixed oil is associated with the content of unsaturated fatty acids in its composition, the higher the saturated/unsaturated fatty acids ratio in a fixed oil, the great the tendency to increase of the melting point.
Nigella sativa seeds contain 0.4-0.45 w/w volatile oil, and more than 30% fixed oil (El-Alfy et al.
Reversed-phase TLC (thin layer chromatography) was carried out following the method outlined in the British Pharmacopoeia for identification of fixed oil. 4 [micro]1 of a 0.5% w/v solution of the fixed oil in chloroform were applied to the TLC plate.
sativa fixed oil to test its antibacterial and antifungal activity, and the result shows a validation for the folk use of this oil as an antibacterial and antifungal medicine .

"Now that the first generation of fixed oils
has been on product labels for a few years, we're expecting a new wave of exotic oils with product-enhancing benefits to drive differentiation in the personal care area," Lauzurica says.
A solution was formed, which on cooling becomes viscous, indicating positive saponification test for fixed oils. But formation of non-viscous emulsion was indicating negative saponification test for volatile oils.
Fixed oils form permanent staining upon the paper but volatile oils do not stain.
