Are there any well-founded studies that authoritatively demonstrate negative effects from the use of nail polish, particularly in children?
I've been brought into the fray of a couple of folks who are having a rather serious debate of whether or not a child of 6 or 7 years of age should be allowed or discouraged from wearing traditional (not the "safe brands") nail polish. It was my opinion that it is better err on the side of caution and that one should rather be safe than sorry, opting for safer non-toxic alternatives if fingernail paint must be worn by such a young child.
The debate has boiled over into allegations of quack science and over-caution. Seems absurd to me, but I wanted to do some more research into the biology of the matter.
A recent report appears to urge on the side of caution, but could someone help to point me in the right direction with regards to substantiating valid scientific claims and studies that fingernail polish can, has and/or does contain harmful material that should not warrant careless usage, especially by younger children who may be more hormonally susceptible to adverse effects?
I'm really looking to button up the "quack" or kooky science arguments if possible and to put this debate to proverbial rest.
