Several novel classes of corrosion inhibitor actives have been identified in a large synthesis and testing program that display both exceptional corrosion performance, and improved environmental properties. These actives have been evaluated against a number of other common classes of"green" corrosion inhibitors by comparing their performance, toxicity, and biodegradability. Actives that passed target thresholds in these assessments were then formulated and tested against a commercial
product known to perform well in aggressive high shear systems. Test data shows that these formulations perform as well as or better than the performance standard. Keywords: corrosion inhibitors, environmental, low toxicity, biodegradable, high performance.
