Buy nail polish free of dibutyl phthalates and toluene instead of standard brand-name polish made with standard toxins. Nail polishes are among the most dangerous cosmetics. Toluene is linked to cancer, and both toluene and dibutyl phthalates are associated with developmental toxicity. You'll save up at least $10 a year, but the real savings are ecological. Fewer toxic chemicals means reduced risk of damage to wildlife, fish and ecosystems.
