Diols and polymeric glycols in dishwashing detergent compositions

The present invention relates to liquid or gel dishwashing detergent compositions suitable for use in manual dishwashing operations. These compositions contain amphoteric and anionic surfactants, organic diamines, and solvents selected from the group consisting of diols and polymeric glycols and mixtures thereof as well as other detergent adjuvants. These components, in the combinations disclosed herein, serve to impart preferred food soil cleaning, handling and sudsing characteristics to such dishwashing detergent products. Disclosed are detergent compositions comprising organic diamines, anionic surfacants and amphoteric surfactants including amine oxide for hand dishwashing which, by incorporating certain organic solvents, results in a liquid dishwashing detergent composition that is not only a more effective cleaning agent, but also offers improved physical and enzymatic stability and more convenient rheology and handling characteristics than typical liquid dishwashing compositions.
