I agree with Merlin.
These products are manufactured by huge corporations, credibility of their products is key to their success. They have their own group of researchers to run studies and produce statistics on the effects of certain ingredients. Statistics can be manipulated in all kinds of way to suit whoever is trying to prove a point.
Research that surfaces countering the products credibility is instantly slammed by these companies and they'll go to a lot of effort to stop it being leaked to the press. At the end of the day all the press care about is money and how much they can make on a story or a payment of silence. They certainly don't have the nations health at heart.
That being said we should all be aware of the ingredients in the products we use on our babies. They all come with ingredients labels. When in doubt do your own research and draw your own conclusions as I'm sure there will be more products that will be scrutinised in the future. Flouride tooth paste, sugar free chewing gum, diet drinks, cling film (to name a few) have all been under discussion about containing carcinogenic ingredients yet they are still widely sold and consumed with no real fear.
I think it's good when these issues are highlighted as it makes us realise we need to make more of an effort to understand these ingredients and not blindly trust these pharmaceutical companies.
