Abstract
A surfactant stabilizer and method for aqueous boiler treatments is disclosed. The method includes using the combination of one or more lower alkyl or substituted amines or phosphoric acid with nonionic surfactant boiler water treatments. The addition of one or more lower alkyl or substituted amines or phosphoric acid stabilizes the nonionic surfactant boiler water treatments by increasing high temperature stability and/or high salt concentration tolerance.
