In June of 2017, a group of 200 scientists and medical professionals called on the international community to ratchet up restrictions on the production and use of triclosan and triclocarban – 2 antimicrobial chemicals found in shampoos and cosmetics. They cite “extensive peer-reviewed research” which suggests the ingredients are potentially harmful. 
In late 2016, the FDA banned 19 chemicals in hand and body soap over concerns about their effect on human health and the environment. Despite the ban, dangerous chemicals are still commonly used in other personal care products.
A senior scientist with the Environmental Working Group (EWG), David Andrews said:
“Other ongoing uses are not addressed by the recent FDA action, and more needs to be done.” 
The group of scientists and medical professionals said in a statement published in the journal Environmental Health Perspectives that the chemicals, which have been used for decades, should be reserved for use only in situations where there is an “evidence-based health benefit.”
