  • Compositions containing nonionic surfactant and sulfonated aromatic compatibilizing agent
    Patent number: 4123395
    Abstract: Bleach-free detergent compositions for use in automatic dishwashers comprising an alkoxylated nonionic surface-active agent and a sulfonated aromatic compatibilizing agent. Preferred nonionic surfactants include ethoxylated nonionics and preferred compatibilizing agents can be selected from xylene-, toluene-, cumene-, benzene-, trimethylbenzene-, ethylbenzene- and ethylmethylbenzenesulfonate. The instant compositions possess enhanced anti-redepositon properties for soils composed of grease and grease-protein complexes thereby providing impeccably cleaned objects which are virtually free of spots and streaks.
