Abstract
Surface treatment compositions containing selected phosphonic acid compounds are disclosed. The compositions contain major levels of surface-active agents in combination with additive levels of the phosphonic acid compounds, and, in accordance with needs and objectives, conventional optional ingredients and additive agents. The inventive compositions can provide significant performance benefits, among others novel synergies and eminently desirable regulatory and environmental acceptability.
