Today I bought a squeegee window cleaner at an auto store.  On the back of the packaging I just happened to see this notice:

I live in Massachusetts, which is where this squeegee was purchased.

Per this statement it contains chemicals, known to the state of California, to be harmful to humans.  My question is:  are the chemicals this product contains known to the other 49 states to be harmful to humans as well?  Because if California has found the chemicals to be dangerous, shouldn’t the other states also find them to be dangerous?

Another question:  if this product is so dangerous because of what it’s made with, why is it being sold?  I guess that answer lies at the bottom of a cigarette butt.

By the way, I did wash my hands after using it.
