Why does Crackle Nail Polish Crack?

The science behind the crackle…

  • The crackle glaze is actually formulated the exact opposite way you would normally want a nail polish to work.
  • A quick drying solvent (such as ethanol) is added to the glaze.
  • Ethanol evaporates quickly when exposed to air due to weaker chemical bonds
  • This makes the polish dry quickly and unevenly, therefore resulting in cracks.
  • Normally you want slow, even drying nail polish to ensure a smooth, glossy finish but by adding the solvent to the formula, the nail polish is viscous and results in an imperfect film…
  • This shrinks as it dries…resulting in the cracks and crevices that show off the base coat.
