Abstract
Aqueous liquid dishwashing detergent compositions are prepared that exhibit improved detergency performance and foam stability over a range of water hardness levels. A preferred formulation incorporates a three component mixture: an anionic surfactant, a nonionic surfactant, and an amido amine oxide to provide a detergent having good detergency performance and foam stability over a range of water hardness levels. Another preferred formulation incorporates a three component mixture: an anionic surfactant, a nonionic surfactant, and an alkyl ethoxylated carboxylate to provide a detergent having good detergency performance and foam stability at high hardness levels.
