Fat/oil soluble Vitamin c
Hi Everyone,
I am looking for a fat soluble Vitamin C ingredient. I would prefer it to have good penetration properties in liquid form. Actually I really liked VCIP from Nikkol however it is quite pricy because of the distributor in Turkey. Anything better than ascorbyl palmitate could help.
Thank you -

3-O-Ethyl Ascorbic Acid from Sandream Impact
-
3-0-ethyl ascorbic acid is water soluble isnt it?
-
It actually claims to be water and fat soluble. I’ve found it to be soluble in neither to be honest.

Expensive but excellent. -
it has a structure very close to ascorbyl palmitate. What about its stability?
-
Stability is up to you! But so far the system I have created has remained stable for 3 months in airless packaging.
-
What is criterion for stability and method?
-
Ambient temperature 30 - 35C. Has it turned yellow or not.
-
no oxidation test?
-
That IS the oxidation test!
-
should be easy to run via HPLC at Tsub zero and after three months at 38C to provide 2 year shelf life.
