Tributyl tin is a chemical found in disposable nappies - one of the main concerns about their use.http://www.nappies.net/tbt.htm
However it is also apparently found in polyutherane - the stuff PUL wraps are covered in. while wraps arent as close to a baby's skin as a disposable nappy would be, should it be worrying?
Understandbly, it would probably be impossible to not come into contact with this stuff, as it is in many plastic products which we are surrounded by everyday.
But is it misleading to tell cloth nappy parents that their baby is much safer from chemicals than babies who wear disposables? xx
