Definition of Methyl Methacrylate – MMA

  1. MMA in its liquid form has been banned for use in the nail industry due to the severity of allergic reaction and damage to the natural nail plate. It adheres so tightly to the nail plate that it can literally rip the nail plate from the nail bed under pressure from a blow or trauma to the nail. MMA is so hard that it can take hours to soak off in pure acetone (not a safe practice) — so it must be filed from the nail plate with a heavy abrasive or electric file.
