This study was conducted to investigate the quality characteristics of the natural dishwashing liquid added with the mixture extracts of Curcuma Longa L. (CL), Morus alba (MA) and Ecklonia cava (EC) at various concentrations. The pH and lightness of the natural dishwashing liquid were reduced by adding the mixture extracts, while the turbidity was increased. The natural dish washing liquid added with mixture extracts was shown to display strong antimicrobial activities against L. monocytogenes compared to that of control. Also, it revealed that antioxidant activity was increased depending on concentrations. However, natural dishwashing liquid added with mixture extracts showed the low detergency efficiency. In sensory evaluation, the natural dishwashing liquid containing CL 0.5%, MA 0.25% and EC 0.25% was preferred than the control and it showed negative result in skin patch test. These results suggest that the addition of CL 0.5%, MA 0.25% and EC 0.25% positively improved the qualities characteristics in the natural dish washing liquid.
