Science
Mechanism of Action
Upon exposure to specific UV light wavelengths, this monomer undergoes a rapid polymerization process, transforming from a liquid state into a rigid, cross-linked plastic film. Its unique molecular structure, featuring a dicarbamate link, balances hardness with high-impact resistance to maintain the integrity of the nail coating.
Research
Clinical Evidence
High confidence99%
Key findings
- 01 Identified as a weak sensitizer based on LLNA testing at 10%, 25%, and 50% concentrations.
- 02 Deemed safe for nail plate application provided skin contact is strictly avoided.
Transparency
Dusting Analysis
In nail systems, this is a primary structural component used at high concentrations; however, in general skincare, its presence would be highly irregular and likely indicative of a labeling error or contamination.
The Formula
Formulation
Stability
Highly sensitive to UV light and heat; storage must remain below 38°C (100°F) to prevent premature polymerization. Requires oxygen (dissolved air) to maintain stability.
Synergies
- Photoinitiators
- Methacrylate diluents
Conflicts
- Peroxides
- Strong oxidizing agents
- Copper
- Iron
- Rust
- Strong bases
Safety
Safety Profile
Its larger molecular weight (470 g/mol) reduces skin penetration compared to smaller monomers like HEMA, but it remains a potential allergen. In the EU, it is restricted to professional nail products and must carry a warning regarding allergic reactions.

Verdict
While essential for durable nail enhancements, its sensitization potential and professional-only status make it unsuitable for precision facial skincare.
