Hi
I have a question from a client about what tests they can perform on their facial oil. It consists of all natural oils.
Is there any tests that would be good to perform on this oil for marketing claims, stability, rancidity etc? They are after actual chemical tests which I think would be expensive but if anyone has any ideas for tests please let me know.
Thanks

the peroxide value (determined by titration with iodide in acidic conditions) will give you an idea of rancidity - the lower the value, the better
