That's a good point - the liquid doesn't say purify. The tablets, in the MSDS, says:

Quote:
1.2. Relevant identified uses of the substance or mixture and uses advised against
Use of the substance/mixture : Recommended use*: Approved only for uses listed on the FIFRA label.
* The “Recommended use” identified for this product is provided solely to comply with a Federal requirement and is not part of the seller's published specification. The terms of this Safety Data Sheet (SDS) do not create or infer any warranty, express or implied, including by incorporation into or reference in the seller's sales agreement.


Kinda strange as well.

I don't use the liquid, though I have in the past. Not sure I will in the future, so thanks for bringing this up.

But note that all it claims to do is "kill odor causing bacteria and enhances the taste of stored potable water." Note that it doesn't say "purify" as the tablets do, because to do so would be illegal and untrue.

As for the EPA Registration, here is what the application says:

A 2% Aqueous Solution of Chlorine Dioxide for Use in controlling the Build-Up of Slime in water storage containers. Kills Odor-Causing Bacteria and Enhances the Taste of Stored Potable Water.


That is not all that we as backpackers are faced with when we pull water in the backcountry.
