This does not sound safe, even assuming that it's "food safe." Sodium hydroxide is not a safe, ingestable, material

It's frequently used in food. IR..

The correct word is "potable". As in you can put it in your cooking pot.

Your not saying how much you need wwtp2014, but these guys sell a lot.

It is usually not required to use food grade sodium hydroxide for potable water applications. After all, sodium hydroxide is just a basic commodity chemical.

However, if you want potable water grade chemicals (Drinking Water Treatment Chemicals), you can spend a little more and get NSF60 approved grade for potable water.

See the link. You may also contact the manufacturers directly.

The same manufacturers sell the "food grade" quality chemicals as well.

Don't have anything for the Food Chemicals Codex (FCC). Not sure it would be helpful.

If you look up Food Chemicals Codex (FCC) on Worldcat, you probably will be able to find one in a library near you.
