ABSTRACT:
A method of stabilizing aqueous system solubility of a transition metal salt, polymeric agent corrosion/deposition control combination at neutral pH is disclosed. The addition of an aliphatic hydroxycarboxylic acid to such corrosion/deposition control combinations was found to enhance corrosion/deposition inhibition while providing for a stabile combination at neutral pH.
