Hi everyone, fairly new here but this looks like a great forum!

My question is about how to preserve an ascorbic acid solution. I have done a bunch of research and so far have only been able to find preservatives that are used in food such as sodium metabisulphite and sulphur dioxide. My question is: are there stronger antioxidants that are not necessarily food safe. I only have a high school level of chemistry so please forgive me if there is some well known group of antioxidants.
