Antioxidant for water phase
I am troubleshooting some oxidation in an emulsion and would like to add an antioxidant that is effective on the water phase. I have done some searching on this site and most of the suggestions seem to be things that I am not able to find for sale at any of my my usual sites.
Does any one have any suggestion for water-soluble antioxidants and where I might be able to find them for sale in smaller quantities?
Thank you.

I asked about ergothioneine the other day but didn’t get any replies

ascorbic acid, NAC, Sodium metabisulfite, Sodium thiosulfate (sodium thiosulphate)
One of the last two (I forget which one at the moment)…is what they sell the mommy bloggers as an anti-browning agent for vanillin. They sell it under the INCI: Fragrance.
The last 3…are all pretty fragrant…but used at very low rates…so typically if you have any fragrance at all in the product, it will not carry through.
Why do you think you have oxidation (in the water phase)? Make sure you are not confusing something like tannins in tea…with oxidation.
