Abstract
A light-duty liquid or gel dishwashing detergent composition containing an alkyl ethoxy carboxylate surfactant, magnesium ions, a magnesium chelating agent, and a buffering agent to maintain the pH of the composition from about 8 to 10. High pH and magnesium ions of the composition provide good grease removal properties while maintaining mildness to the skin. The buffering agent and chelating agent of the composition provide superior physical and chemical stability during storage. The preferred type of dishwashing detergent composition is in the liquid form.
