Face serum changes color- Help!
Hi everyone! I got an issue with a water only serum formulation which after a month changes color and from being clear turns greenish/brown. The formula is the following:WaterPropanediolButylene glycolHyaluronic acidSaccharomyces Lysate (Blend with aminoacids and Disodium Succinate)D riboseInositol
Xantham gumAcrylates/C10-30 Alkyl Acrylate Crosspolymer (Ultrez 20)ArginineCaprylyl glycol1,2 HexanediolPhenoxyethanolEthylhexylglycerinDisodium EDTA (0.2%)I suspect that the issue has to do with the presence of the sugars ribose and inositol. Any suggestion would be greatly appreciated! Thank you -

Greenish brown sounds like a microbial problem.
But you could try removing the lysate, ribose, inositol and arginine and see if the problem goes away. Those ingredients are not having any beneficial effect anyway. -
They used ribose with lysine. Did you get a similar color?

@Jimmychemie If the issue is Maillard reaction, you could add some Ascorbic acid, ti see if the issue is resolved. But as @Perry mentioned, many of the ingredients in your formula don’t have any purpose, so if you want rommto keep them for marketing purposes, keep them at the lowest amount possible (0.01% or so).

Thanks everyone for the feedback.
@grapefruit22 yes the mid photo in the 2nd figure (d ribose +lysine) is similar to what I am getting. I will try ascorbic acid or removing/ readjusting quantities and see if the change still occurs.
