The surface cleaning and antibacterial property of the detergent resolved its unifunctionality problem. The antibacterial activities of the detergent were demonstrated through a disk diff usion assay and wipe experiments with Escherichia coli and Staphylococcus aureus . Results showed that the prepared detergent was highly eff ective against E. coli and S. aureus . The results of chemical accelerated tests indicated that the detergent would be eff ective for at least 1 year. The antibacterial property and detergency performance of the high-effi ciency antibacterial liquid dishwashing detergent were compared with those of a commercial antibacterial detergent containing 0.02% o -phenylphenol. The detergency performance of the high-effi ciency detergent reached 97.8% and was superior to that of the commercial antibacterial detergent.展开更多

The foam and oil-removing performance of amino acid surfactants in alkaline condition were test to discuss feasibility of amino acid-based surfactant from natural origin as the alternative to traditional nonionic surfactants from petroleum origin in dishwasher detergent. Comparative study was conducted through using various amino acid-based surfactants and nonionic surfactants respectively, together with enzymes and peroxide to formulate dishwasher detergents, and their application properties such as foam performance and detergency were also evaluated when washing different tableware in automatic dishwasher. The results showed that among all tested amino acid surfactants, glutamate surfactants showed low foaming and high oil-removing ability in alkaline condition, and excellent decontamination ability in dishwashing tests.展开更多
