Toothpaste chemical linked to brain damage in unborn babies

A chemical found in toothpaste and other toiletries has been linked to brain damage in unborn babies, a study has revealed.

Scientists are worried after new findings revealed that triclosan can contribute to brain damage in the womb; the study found that pregnant women who are exposed to high levels of the chemical could be putting their baby’s health at risk.

The findings suggest that triclosan can affect blood flow to the uterus, meaning the baby’s brain does not get the oxygen it needs. Last night, researchers involved with the study called for urgent further investigations into the effects of triclosan on unborn babies; Professor Margaret James, from the University of Florida, said that it was clear that there were problems related to triclosan but further research was required to determine the extent of the problems.

Triclosan is an antibacterial chemical, which is commonly found in deodorants, toothpastes and handwashes; recently, there have been concerns over health problems associated with triclosan and The US Food and Drug Administration announced that it was conducting a major review of the chemical.

The most recent study involved testing sheep; the study found that triclosan interrupted the action of the enzyme, which facilitates the circulation of oestrogen in the womb. Oestrogen is vital because it keeps the main artery open to allow oxygen-rich blood to reach the baby; if there are not sufficient levels of oestrogen, the artery will narrow and oxygen will not reach the foetus.

In the UK, triclosan is covered by the EU Cosmetics Derivative and officials say the chemical is safe in small doses; however, GlaxoSmithKline has removed the chemical from many of its products, including Aquafresh and Sensodyne toothpaste and Corsodyl mouthwash. Elizabeth Salter-Green, director of ChemTrust, advised pregnant women to steer clear of products that contain triclosan.
