N-acyl ED3A chelating surfactants are new classes of compounds which act as strong and gentle surfactants and powerful complexing agents. They are compatible with detergent enzymes and activated bleach systems and show synergistic with other surfactants, especially in the presence of water hardness ions. They act as corrosion inhibitors for bright mild steel and passivate stainless steel under alkaline conditions due to their unique properties, they will find widespread use in a wide range of detergents and personal care applications.
