Science
Mechanism of Action
Forms a breathable, hydrophilic film layer that repels external contaminants and water while minimizing trans-epidermal water loss. Acts as a protective buffer between harsh surfactants and skin's natural lipid barrier, preventing protein degradation during cleansing.
Research
Clinical Evidence
High confidence2.5%
Key findings
- 01 Significantly reduces surfactant-induced keratolysis and provides lotus effect that delays re-soiling and moisture loss
- 02 Enhances thermal protection for keratin fibers and improves surface wetting force, leading to smoother texture in self-assessments

Dusting Analysis
As a functional film-forming polymer with specific concentration requirements, this ingredient is typically used at effective levels rather than dusted
The Formula
Formulation
Stability
Maintains optimal viscosity and film integrity within pH 6.0-7.0 range. Highly stable in electrolyte-rich and dye-containing systems.
Conflicts
- High concentrations of anionic surfactants may cause complexation depending on crosslinking density
- Strongly acidic environments below pH 3.5 may cause polymer precipitation
Safety
Safety Profile
Generally recognized as safe within typical cosmetic usage ranges (0.05%-10%). High molecular weight makes skin penetration unlikely, contributing to low toxicological risk profile.
