ABSTRACT:
An aqueous concentrate useful for treating boiler waters to scavenge oxygen therefrom which contains at least 0.3% by weight of either gallic acid or propyl gallate. This aqueous concentrate has a pH adjusted to at least 8.5 by a water-soluble neutralizing amine of the type used to treat boiler waters. Additionally, a method for treating boiler waters with an oxygen scavenger.
