The use of chemicals has pervaded most of our manufacturing industries. The trouble with this trend is that many of these are actually harmful to us, if we but knew. As and when evidence is gathered showing the poisonous nature of any one of them, the concerned authorities resort to banning it. Perhaps, such is the future of TRICLOSAN, the chemical used in many toothpastes and soaps?
Triclosan, a common chemical used in a wide array of products, from antibacterial soaps to toothpastes and many more uses, has been associated with life-threatening issues. A new study has shown that the substance causes liver cancer in mice. Previously, it was suspected of other less severe consequences such as the disruption of certain hormones, and promoting some bacterial strains, all of which questioned whether the positive points of triclosan outweigh its drawbacks. The new study has most probably tilted the balance.
The researchers of the new work showed that triclosan impacted negatively on liver integrity and function. The mice were subjected to exposure to triclosan for 6 months – a time period which is equivalent to 18 years in the life of a human. The observations that were made from then entailed greater vulnerability to chemical-induced liver tumours. The results were interpreted in relation to triclosan’s action on body proteins. Seemingly, the chemical interferes with a protein that is known to get rid of foreign chemicals. Also, the tumours that did develop were found to be bigger and more frequent when compared with mice not exposed to triclosan.
The FDA was already considering banning the chemical in the light of previous evidence generated showing that triclosan might not be as good as it was initially thought. Perhaps, the new study will add in more weight, and influence the decision-making processes? It is expected that by 2015, a verdict will be pronounced about the use of triclosan.
