Results and discussion

Solubility in organic solvents / fat solubility
Medium:
other: Hexane
Test substance stable:
yes
Details on results:
All constituents are very good soluble in hexane. Hexane is the technical extraction solvent in oil mill processes and extracts triglycerides and free fatty acids as well.
