Questions over the safety of the antibacterial chemical triclosan have raised questions about the FDA approval process of food and soap ingredients. Triclosan has been linked to cancer cell growth and disrupted development in animals. Due to the concerns, many manufacturers are halting use of triclosan, regulators are reviewing its safety and usefulness in soap and toys, and governing bodies have banned it in many products. Meanwhile, based on FDA approval, the chemical is being used every day by millions of Americans in some Colgate toothpastes and other products.
After four applications for FDA approval, Colgate Total was approved in 1997. Since then, multiple reports and studies have led scientists to describe triclosan use in toothpaste as a “huge risk.”
Colgate was approved through what it described as a rigorous process by the Food and Drug Administration. However, the scientific findings that Colgate used to show triclosan’s safety are controversial. The 35-page summary of company-backed toxicology studies were released this year after a lawsuit via the Freedom of Information Act. The National Resources Defense Council sued the FDA for the toxicology data and the FDA released its summary and a previously undisclosed cancer study.
Among the studies were experiments done on mice and rats that showed fetal bone malformations that scientists link to disruption of the endocrine system and change in hormonal functioning. Colgate called the findings irrelevant. Two of these studies linked the chemical to lower-weight fetuses, irregular bone formation, and delayed bone formation in the skull, vertebrae and pelvis. Other experiments done on mice and rats include a 2012 study linking triclosan to reduced fertility in mice and a study in 2013 linking the chemical to lower sperm production and changed sperm shape in rats.
The potential dangers surrounding triclosan involve the disruption of the endocrine system. Newer science suggests that even small doses of some chemicals can affect hormone function, and one biochemistry and microbiology researcher described studies on triclosan as “almost a hallmark of endocrine disruption.” With more research being done due to a global rise in endocrine-related diseases and complications, some chemicals and environmental factors have been linked to problems such as breast, ovarian, and testicular cancer; low birth weight; early breast development in girls; and undescended testicles.
GlaxoSmithKline has remade its oral care products that were formulated with triclosan because the products “may have a negative environmental impact in the future.” Triclosan is not just used in toothpaste, however. Right now, the FDA is reviewing triclosan use in hand soap. Some studies have suggested that the chemical could actually support the growth of bacteria including the type that causes staph infections. Triclosan is also used in in rugs and pet-food dispensers. However, companies such as Johnson & Johnson, Proctor & Gamble, and Avon Products have removed triclosan from their products.
In 2010, the European Union banned triclosan in products that come into contact with food, citing a “rapidly developing scientific database,” which included studies on thyroid and hormonal effects. The first state to pass a triclosan ban, Minnesota will prohibit the sale of triclosan-based cleaning products, except those approved by the FDA, starting in 2017.
Whereas the FDA is responsible for protecting consumers from potentially dangerous products, sometimes FDA-approved drugs and manufacturer goods can lead to serious complications.
