1. Get some L-Ascorbic Acid.2. Get some Glycerin.3. Go into the lab.That is how I would get my answer. Searching for “ascorbic acid solubility” would also be a good start.Very first result;

If you look just at the reference, it lists the solubility of L-Ascorbic acid in Glycerin as 0.05 gm/ml which equates to 5% Wt/volume in pure Glycerin or 5 grams Ascorbic acid in 100 ml of Glycerin.

I will say it again, you will not get an anhydrous system with glycerin. It is a humuctant not a solvent. You either need to find a solvent or just accept that the formula can’t be stabilized because you don’t have access to derivatives.

Why don’t you try a mixture of 1,3-Propanediol and Glycerin.

Hmmmn! There was a report I read where it says it can dissolve in glycerin which is heated… So I had to throw the question to the house

@Microformulation @ngarayeva001 I’m trying to make an anhydrous vitamin c serum and I want a solution that LAA and HA can dissolve in without it being necessarily water which is receptive to heat to enable me Infuse powdered leaves extract in it in a double boiler then add other ingredients ,mostly antioxidant liquid extract and ferulic acid so I was thinking glycerin could work, then what solubilzer would be ideal in emulsifying vitamin e oil into such a mixture? Thanks.

Meanwhile I can only have access to glycerin, propylene glycol as base solution, would this work?
-
Look, why don’t you just bloody well TRY IT and SEE instead of asking endless questions! You might learn something.

Anhydrous LAA systems are not very pleasant to apply. You either make an aquaneus gel of LAA and HA plus your extracts (that won’t do much) that will be pleasant to apply and oxidize very soon or you make a minimalistic gritty mixture of propanediol and LAA and skip all other ingredients. And it will be so heavy that you won’t need any glycerin. I think that propanediol might be replaced with propylene glycol. Sorry but you cannot have it all when you have such a limited access to ingredients.

You don’t want a mostly glycerin formulation on your skin.
Pure or highly concentrated glycerin is actually drying to the skin and may cause irritation or even blisters if left on too long.
