Lipstick chemical alert: Ingredient in hundreds of household products ’causes heart problems’ -Triclosan

chemical commonly used in lipsticks, face  washes and toothpaste may cause heart and muscle problems, according to  scientists.

They found triclosan, which is in hundreds of  household products, can hinder the process by which  muscles, including the  heart, receive signals from the brain.

In tests on mice, they noted a ‘dramatic’ 25  per cent reduction in heart function within 20 minutes of exposure, and warned  there is ‘strong evidence’ it could affect human health.

However regulators and other experts insist  triclosan levels in products are safe, and that the doses injected into the mice  were higher than those to which humans would ever be exposed.

Although previous studies have found that  triclosan may have links to thyroid and fertility problems, this is the first  time its effects have been tested on muscles.

Scientists had thought that the chemical – which was devised to prevent bacterial infections in  hospitals – was  metabolised quickly by the body without harmful effects.

However, the researchers at the University of  California say it may remain active and be transported to organs, causing  damage.

Professor Isaac Pessah, who led the study,  published in the Proceedings of the National Academy of Sciences, said: ‘These  findings provide strong evidence that it is  of concern to both human and  environmental health.

‘For someone who is healthy a 10 per cent  drop in heart function may not have an effect, but if you have heart disease it  could make a big difference.’ His team injected a group of mice with triclosan.  They saw a ‘significantly reduced’ function in the heart’s left ventricle within  20 minutes.

Another test looked at the mice’s skeletal  muscles by getting them to grip wire mesh. Those injected in the past hour had  an 18 per cent fall in their grip strength – although it was restored within a  day
