No-Burn[R] fire and mold retardants and reactants (dual-purpose) are a highly advanced line of nontoxic, noncarcinogenic liquids that make the potential risk of fire and mold a thing of the past. Under simulated treatment conditions in samples of distilled water and wastewater, 11 new compounds were formed from acetaminophen within an hour, the time the reactants would likely be in contact at any plant.
