Guessing that works as the same concept of Vanilla browners…in which case you can use

Sodium Metabisulfite

or

Sodium Thiosulfate Pentahydrate

But these should not be used without extreme care and caution.  Not for amateurs.

Are they corrosive? Would I treat like I were using glycolic and SA?

Not sure I understand your question.

Did you mean antioxidant? 

A good water soluble chelator is Sodium Phytate.

I think any chelator would be a good substitute, since I am not aware that Vit. E works as a chelator.

yes as an antioxidant or to stop a toner with kojic acid from turning yellow.
