Science
Mechanism of Action
As the carrier solvent evaporates post-application, the polymer chains align to form a flexible, microscopic film. This matrix acts as a physical moisture-lock barrier that prevents trans-epidermal water loss while simultaneously anchoring other active compounds to the skin to prevent them from being washed or rubbed off.

Clinical Evidence
High confidence1.5%
Key findings
- 01 Concentrations between 1.5% and 5.0% demonstrated high efficacy in maintaining cosmetic durability and providing significant resistance to high humidity levels.
- 02 Usage at 0.1% to 2.0% effectively serves as a secondary film-former, enhancing the long-wear properties of topical formulations without increasing skin sensitivity.
Transparency
Dusting Analysis
Because it is effective as a secondary film-former at levels as low as 0.1%, concentrations below this threshold may be considered 'label dusting' where no functional barrier benefit is provided.
The Formula
Formulation
Stability
Highly stable across a broad pH spectrum; however, formulators must avoid excessive heat to prevent premature polymerization or matrix degradation.
Synergies
- Hydrophobic active ingredients
- UV filters
- Volatile silicones
Conflicts
- High concentrations of surfactants
- Strong oxidizing agents
Safety
Safety Profile
Safety is contingent on ensuring residual monomers, specifically Butyl Acrylate, remain below 100 ppm to eliminate the risk of sensitization.
