Anti-bacterial additive is known carcinogen.
from Environmental Defence
Triclosan, the active ingredient in most antibacterial products, is a known endocrine disruptor, which can cause thyroid problems and cancer. The Canadian Medical Association has called for it to be banned from consumer products, out of concern that triclosan could contribute to antibiotic resistant bacteria, also known as "superbugs". Triclosan also contaminates the environment, washing down our drains to pollute rivers and lakes.
