Is this sodium carbonate safe for my reef tank?

[nim6us]

I'm trying to find a suitably safe vendor to buy sodium carbonate for my 2 part solution. I'm hoping @Randy Holmes-Farley or someone qualified can review this data sheet and let me know if there's enough information to determine if this will be safe to use in my reef tank.

Do you have a link to the actual product? Safety data sheets don't generally provide needed info on purity.

Yes of course no problem:

However I don't know how helpful that is. I've been looking for something that say "grade" and I can't seem to find anything that lists USP or ACS, not even anything that says "food grade". I don't know if that's because I'm in the UK and there's perhaps a different set of terms?

Actually looking for calcium chloride I found this company that does actually say food grade, presuming that should be okay?

It’s hard to know for sure if it is suitable, but it likely is.
