Science
Mechanism of Action
This ingredient functions by creating a physical barrier upon application, forming a robust, hydrophobic film. This film improves product longevity, water resistance, and overall adhesion, effectively sealing the skin's surface from external factors and environmental stressors.

The Formula
Formulation
Stability
The monomer form requires the presence of oxygen for stabilizer function to prevent polymerization and must be stored below 35°C. Contact with iron(III)-ions should be avoided as they can weakly initiate polymerization.
Conflicts
- inert gases (during storage)
- temperatures exceeding 35°C (during storage)
- iron(III)-ions
Safety
Safety Profile
The CIR Expert Panel previously concluded that related methacrylate ester monomers are safe in nail products when skin contact is strictly avoided due to their sensitizing potential. The monomer 2-ethylhexyl methacrylate is explicitly classified to cause skin irritation and may cause allergic skin reactions. This ingredient is also recognized as an FDA Food Contact Substance.
