You do not need anti-bacterial soap for everyday household uses.
For household uses, regular soap is just as effective at killing germs as soap containing triclosan, according to a 2005 Food and Drug Administration Advisory Committee. Triclosan is a known pesticide most frequently found in soaps labeled as “antibacterial.”
Choose soap that does not contain triclosan.
Avoid products that are labeled “antibacterial” or look for tricolsan in the ingredients. Choose glycerin, Castile or vegetable-based soaps in bar or liquid form.
