caryfh Posted December 31, 2010 Share Posted December 31, 2010 I would like to incorporate DL-panthenol into a serum recipe I have, but cannot figure out how to go about this since it is an anhydrous formulation, and panthenol is soluble in water. Ugh. The formulation uses...CyclomethiconeDimethicone CrosspolymerTocopherolsAscorbic AcidSilicaThe ascorbic acid also said it was water soluble, but that it does best in anhydrous formulations, so somehow that is working in this situation.

CareBear Posted January 9, 2011 Share Posted January 9, 2011 (edited) The ascorbic acid also said it was water soluble, but that it does best in anhydrous formulations, so somehow that is working in this situation.Where did you read that it works best in anhydrous? there is an anhydrous FORM, is that what you mean? but this means there's no water in the ascorbic, not that it dissolves in anhydrous situations.It's soluble in water, ethanol, and glycerin, and insoluble in oil.This article http://complex31.com/articles/JCD-T2-Asc-Immi.PDF talks about using "microfine particles" of ascorbic acid in an anhydrous formula. I didn't finish reading it, but I'm guessing that it's moisture from the skin that somehow dissolves the particles and allows them to interact with skin.
