  • Chelating system for a polymer lined steel container
    Patent number: 9650205
    Abstract: A chelating system for inclusion in a composition at least stored in a polymer lined metal passivated steel container which provides for stability of both the composition and the container. The composition preferably is a cleaning composition including a color-changing dye or indicator. The chelating system provides for stable storage of the composition through preventing degradation of the dye/indicator over an extended storage time. The chelating system included in the composition has a low affinity for the passivation metal on the steel container which provides for stability of the polymer liner present over the passivation layer and, thus, provides for the stability of the container. A preferred combination is a cleaning composition including (a) tetrasodium iminodisuccinate as the chelant and (b) a pH sensitive color-changing dye/indicator, in combination with a PET-lined chromium passivated tin-free steel container.
    Type: Grant
