Zoya was one of the first nail polish brands to remove the toxic ingredients from the nail polish. Over the years Zoya has gone from only removing a few toxic ingredients to being 10-free! That means they have eliminated 10 of the most toxic ingredients from their nail polishes! These ingredients include: Formaldehyde, Formaldehyde resin, Dibutyl Phthalate, Toluene, Camphor, TPHP, Parabens, Xylene, Ethyl Tosylamide and Lead. They were also the first nail polish producers to create a working fast dry top coat for the nail polish.
