Abstract
A high-efficiency liquid dishwashing detergent was prepared by using oregano essential oil as an antibacterial agent. The surface cleaning and antibacterial property of the detergent resolved its unifunctionality problem. The antibacterial activities of the detergent were demonstrated through a disk diffusion assay and wipe experiments with Escherichia coli and Staphylococcus aureus. Results showed that the prepared detergent was highly effective against E. coli and S. aureus. The results of chemical accelerated tests indicated that the detergent would be effective for at least 1 year. The antibacterial property and detergency performance of the high-efficiency antibacterial liquid dishwashing detergent were compared with those of a commercial antibacterial detergent containing 0.02% o-phenylphenol. The detergency performance of the high-efficiency detergent reached 97.8% and was superior to that of the commercial antibacterial detergent.

A high-efficiency antibacterial liquid dishwashing detergent that resolved the unifunctionality problem of commercially available detergents was prepared in this work
The detergency performance of OD-2 reached 97.8% and was superior to that of a commercial antibacterial detergent, which had a detergency performance of 96.4%. They showed antibacterial activities against S. aureus and E. coli, but the prepared detergent was more effective against tested bacteria and safer for the human body
Summary
Detergents are commonly used in domestic and industrial cleaning. They can be classified as hard surface cleaners, laundry detergents, and dishwashing detergents in accordance with their applications [1]. Rhoades et al [17] showed that OEO is an effective antibacterial additive to hand-washing and surface-cleaning detergent solutions and is a potential alternative to triclosan and chloroxylenol. Rhoades et al [17] reported that commercial high-efficiency antibacterial liquid dishwashing detergents containing OEO have been developed.
