Triclosan-GettyA chemical ingredient of cosmetics, soaps, detergents, shampoos and toothpaste has been found to trigger liver cancer in laboratory mice, raising concerns about how safe it is for humans, scientists said. Triclosan, a commonly used anti-bacterial agent added to bathroom and kitchen products, promotes the growth of liver tumours in mice fed relatively large quantities of the substance, a study has found. The research is the latest to link triclosan with cancer and liver disease, but other scientists have urged caution over the findings suggesting that they do not prove a direct causal link between the chemical and the ill health of people exposed to it.
