But then we use countless chemicals in practically every modern product. How do you know these chemicals in <insert a product that isn't essential for survival here> are safe over decades of use? Since we cannot rely on current knowledge on chemical safety as very few are tested in all concentration over lifetimes, none of it can be considered perfectly safe. The rational stance is to evaluate the information given the evidence at hand, not according to some arbitrary threshold of negative proof.
It isn't negative proof. Many pesticides on the market have been shown to cause birth defects, cancers, and other diseases. Some even say so on the label. (I have applied commercial herbicide and pesticide and have read the accompanying MSDS) These aren't what appear to be non-toxic chemicals that would surprise everyone if they turn out to have negative long term effects at low levels. They are chemicals that we know to be toxic. Again long term safe exposure levels are a guess at best.
