My Vitamin C Serum is Sticky
I have been trying to make a vitamin C serum with Sodium Ascorbic acid (SAP).
SAP - 20%
Hydroxy Ethyl Cellulose - 2%
Propylene Glycol 2%
Glycerine - 2%
Alow vera extract - 1%
Witch Hazel Extract - 0.5%
Grape Seed Extract - 0.5%It seems to be sticky, literature says I should try adding Niacinamide and may give better result. Kindly suggest.

I’ve used Sodium Ascorbyl Phosphate at 20% before and I’ve also had an issue with stickyness. That’s a lot of bulk material to try and get into water. If you can cut down, you should (it’s stable from what I’ve seen but I don’t advise it because I noticed an unpleasant smell). You could also try triethyl citrate as I’ve heard that can help cut down on tacky feeling.

Try changing your thickener to Ultrez 10 and/or xanthan gum as HEC may be the problem.

@EVchem I was reading the literature, it seems like Triethyl citrate not safe chemical for the skin. Maybe something else to take out the tacky feeling.
I was thinking ethyl ascorbic acid but that almost double the cost of Sodium ascorbic acid. It will surely increase the overall costing. -
@”DRBOB@VERDIENT.BIZ” HEC does have the problem as it started separating after a while, so I can’t really use it. I used ultrez 10 that working but still not able to improve the sticky feeling.

I would do a knockout to determine cause and if SAP try lowering or use ascorbyl glucoside.
