Gasp! Nail Polish?

I was looking through stuff from the EWG and other groups who focus on green products, trying to find the safest nail polish. I usually use OPI, and happily, it's among the best.There's another company out there called Suncoat that makes water based polishes, and their colors are not bad, but what I want more than any other color is agreat matte gray--no pearliness. That's why I just spent $26.50 on Rescue Beauty Lounge Stormy polish. It damn well better be everything it's reviewed to be! And it has the same set of non-toxic claims as OPI, by the way.
