In the state of minnesota; they band the toxin since the year of 2014 due to the research conducted on the chemical background of the toxin. In the research, the chemical was tested on rodents which had some significant effects on the endocrine system. They found that the chemical alters the hormones needed in reproduction. Furthermore, one cleaning product that is used in schools but also at home is simply toothpaste. The brand of “colgate total ” uses the chemical because it supposedly helps protect against the disease of gingervitus. But on the opposite side, the toothpaste brand of crest does not use triclosan which is a huge bonus in the state of minnesota. The main side effects of triclosan are: increased antibacterial resistance, stays in your bloods for a long period of time, and associated with allergies and hay fever.
