Science
Mechanism of Action
This ingredient utilizes a unique hyperbranched molecular structure to create a flexible, continuous, and water-resistant lattice on the skin's surface. This network effectively traps oils to enhance gloss while ensuring active ingredients—particularly UV filters—remain uniformly distributed and anchored to the skin even under physiological stress or water exposure.
Research
Clinical Evidence
High confidence2%
Key findings
- 01 In vitro testing at 2.0% concentration demonstrated superior SPF retention following water immersion, outperforming conventional acrylate-based copolymers.
- 02 Application tests in the 1.0% to 5.0% range confirmed significant improvements in surface smoothness and light reflectivity (shine) without inducing tactile greasiness.

Dusting Analysis
While often used for its sensory benefits at lower levels, therapeutic water resistance and SPF boosting require a threshold of at least 1.0-2.0%. Percentages below 0.5% are likely included for marketing claims rather than functional performance.
The Formula
Formulation
Stability
Exhibits exceptional stability across a wide pH spectrum, including acidic environments. Its low melting point facilitates easy integration into the oil phase during the emulsion process.
Synergies
- UV Filters (improves distribution and residency)
- Pigments (acts as a dispersant)
Conflicts
- Highly cationic systems (may precipitate if the polymer is neutralized to its anionic form)
Safety
Safety Profile
Classified as a low-hazard synthetic polymer; it is non-irritating and non-sensitizing at standard cosmetic concentrations.
