Advice for working with Resveratrol?
Hi, all.I have seen some conflicting information online about how best to work with resveratrol as part of an emulsion and wanted your advice, please.
-1- I believe some comments on here indicated that it should be added into the oil phase. Is that correct? If so, it would be solubilized into what exactly? (I’m asking because I believe resveratrol is not oil-soluble.)-2- I have seen elsewhere online that a better option might be to disperse it into glycerin (?) and then add this into the cool-down phase, perhaps because of heat sensitivity?Thank you.(Note: I attempted to add this question into one of the older discussions about resveratrol, but was unable to do so.) -

It is not soluble in water. The best solvent for it is PEG400. See this paper.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4427559/I don’t think the glycerin technique will help but I haven’t tried it.
Resveratrol has a melting point ~260C, it is not heat sensitive.

Advice? Sure. Don’t waste your time.

Not commenting on its skin benefits because papers I saw weren’t persuasive, but I managed to dissolve 4% in plain propylene glycol. It took an hour of stirring using a magnetic stirrer. Didn’t even had to heat it.

Not commenting on its skin benefits too.
There’s SalSphere® Resveratrol - encapsulated version. disperse in cool-down phase. -

Can you pls share your experience wnen used in an emulsion after dissolving it in propylene glycol -Does it get oxidized or changes color of emulsion?

Resveratrol is an antioxidant and is prone to oxidation. It can change colour of the product when it oxidises itself. I noticed it in one of the products I made a while but I can’t tell when it happened. The moisturizer was over a year and the resveratrol powder I used in it also changed its colour. Ubiquinone is the same btw.

Agreed.
or if it’s intended for personal use, a suspension in hydrogel is easier to manage, shelf-life should be around 6 mo in fridge.
