All soap is antibacterial in that it removes bacteria from the skin during the washing process. Using triclosan or other "antibacterial" ingredients is no more effective than just using plain soap.

I made my aunt a soap with tea tree and lavender EO (both with anti bacterial properties) and she swore it stopped her from getting small infected scratches after gardening. She always washed her hands with regular soap but that didn't always prevent the infections.
