Thanks Bill but according to their tech sheet it’s insoluble in glycerin. See screenshot

em — aloe vera gel contains water.

p.s. Belassi, I came across your comment re: hydrolyzing oat proteins via a tiny bit of lye and then neutralizing with lactic acid. I could hydrolyze colloidal oats by just cranking up the heat. It’s the same phenomenon as your porridge thickening when cooking. The oats self-emulsify.

Belassi, that “prior art” is old old school. There’s new art in the patent world to make it work.

Bill, I came across a hint towards hydroxypropyl cellulose in another search. Any tips for incorporating it? Ballpark ratios? homogenization procedure? Temperature?

Yes, so water is an incidental ingredient of the final product as the glycerin is a humectant and will draw some from the environment etc. But I need the water to be practically nonexistent. I have a few reasons for it: 1) The % of acids dissolved in glycerin is relatively high, if we had an aqueous solution, the PH would be low and the product would be irritating to the skin. 2) Also l-ascorbic acid is notoriously unstable in water 3) I would then need to preserve the serum (although if the glycerin % is high enough compared to water, say 50-60% and up, I could get away with no preservative, but that still doesn’t help with stability etc.). So I just need it to be glycerin + some sort of geller / thickener that plays nice with it in the absence of water.
