I am working on developing an anhydrous serum which, functionally, consists of just l-ascorbic acid (and potentially other vitamin acids besides it) dissolved in glycerin. I was able to achieve this but the problem of course is that pure glycerin is aesthetically unacceptable to daub onto skin.
Now I have strong reasons to insist on keeping this a water-free formulation, so I cannot just add water and a gelling ingredient (pectin, guar gam, xanthan gum, etc.) to improve the consistency. I need to find a way to gel glycerin (an alcohol) in the absence of water.
Does anyone have any tips? Or other tips for improving the aesthetic feel of this serum so long as they don't require the addition of water?
Many thanks in advance!
