As more and more consumers demand transparency from their products, an increasing number of brands are switching out the toxins in favour of safer solutions. For nails, the worst offenders are formaldehyde, toluene and dibutyl phthalate. And while these — otherwise known as the Big Three or Toxic Trio — have all but disappeared from the majority of modern formulations, many brands are now going a step further. With studies revealing that chemicals in polish can be absorbed by the body in just 14 hours, non-toxic nail varnishes are on the rise, with some formulations eradicating up to 13 of the most commonplace chemicals.
