Why 10-Free™ I hear you ask? The answer is simple. We strip out a lot of bad stuff. While no nail polish can ever be fully free of chemicals, our 10-Free™ brand does not contain formaldehyde, toluene, DBP, camphor, formaldehyde resin, xylene, parabens, fragrances, phthalates and animal derived or tested ingredients.
Kester Black has also never used ingredients ethyl tosylamide, triphenyl phosphate or xylene.
