I’m in the US, we are a physicians only line. I’ve been in regulatory and compliance for many years so I’m not concerned with that. I’m switching to R&D and I’ve been working under our chemist while trying to earn my second degree in science but she is out on vacation for two weeks, hence the help on this issue.

Hummm…. Well I first wanted to make this un-buffered but guess I did my initial math incorrect since my pH wasn’t as close as I wanted it to be. So how do you explain other manufactures out their who make un-buffered solutions which is just the Salicylic Acid and ethanol? You don’t HAVE to have buffers.
I’ll guess I keep playing with it….. Also, I did think of supersaturation, again, guess my math was off, I’ll have to go back and review
O and yes chemical peels are permitted…

I looked down that path but derivatives but get mixed results in how effective they are compared to L-ascorbic acid. Well I guess if I figure it out, I’ll be keeping my process ultra secret!

Yes, I’ve been trying for awhile to do this and have had no success thus far. My formula now consist of no water and it only last about 7-10 days before it starts to turn really yellow. Is there any chemicals that have been shown to help stabilize Vit C at all? How do the big companies get a 20% stabilized Vit C serum but so many people can’t figure it out? Or is the question maybe that it’s not being stabilized but consumers really don’t know the difference anyway? I’ve seen my share of bad, terrible and plan shouldn’t be on the shelf cosmetics.
Also, would a nitrogen puff before induction sealing help keep shelf life of my Vit C formula?
