That doesn’t resolve an ancillary question however. although it appears to be safe to use for water purification purposes (for drinking water), the question remains. In the meantime I will rely on the Calcium Hypochlorite method.

The amount of Sodium Hydroxide that is added is OK for those purposes. It's the same amount that was there in the previous Clorox that was OK'd for those purposes. . . and is actually less in proportion to the concentration of sodium hypochlorite. So when you put in the lesser amount of Clorox to get the same level of chlorine to purify the water, you'll actually have a lower amount of Sodium Hydroxide than before. Follow my logic?

Thank you.

I follow the logic, no problem.

If those are the only ingredients, no problem. If not, then there may be a possible problem with other additives and kidney/liver etc. problems over the long haul.

That is what I want to avoid.
