Ascorbyl tetraisopalmitate VS tetrahexyldecyl ascorbate

Posted by Shams on September 16, 2021 at 11:01 pm

I am after some clarification as whether Ascorbyl tetraisopalmitate is the same as tetrahexyldecyl ascorbate or are they different?
I am really confused and hope anyone can clear this up for me.
TIA

The original one commercialized by Nikko Chemicals in 1996 goes by inci Ascorbyl Tetraisopalmitate, and you can see hexyldecanoyl- drawn in their research.

So I think none of the two inci names are really percise, and the correct should be Ascorbyl Tetrahexyldecanoate.

The name Tetrahexyldecyl Ascorbate would be suggesting it’s made by esterfying 4mol hexyldecanol with 1mol ascorbic acid, which wasn’t to happen. Not sure why it exists, could be patent risk management?
