Science
Mechanism of Action
Forms a cohesive, flexible polymer film upon application that dries to create a protective barrier on skin. The film acts as a binding matrix that holds active ingredients in place while resisting water and mechanical abrasion, simultaneously modifying formulation viscosity for improved application characteristics.
Research
Clinical Evidence
High confidenceN/A
Key findings
- 01 Demonstrated minimal skin irritation and sensitization potential across broad concentration ranges, with formulations up to 0.25% showing low phototoxicity risk
Transparency
Dusting Analysis
Primarily functions as a film-former and viscosity modifier rather than an active ingredient, making dusting less relevant for this polymer
The Formula
Formulation
Stability
Exhibits exceptional pH stability from 2.0-10.0 and becomes water-dispersible when neutralized with aminomethyl propanol (AMP). Supplied as water-based emulsion for easy incorporation.
Conflicts
- Cationic raw materials due to anionic polymer nature
- High concentrations of non-polar products like paraffin waxes
Safety
Safety Profile
CIR-approved up to 25% in leave-on products when formulated to minimize irritation. Requires maximum secondary amine content of 5% to prevent nitrosamine formation. Monomer residue control is critical for safety.
