Science
Mechanism of Action
This ingredient constructs a three-dimensional elastomeric network on the skin surface that remains non-penetrating due to its high molecular weight. It functions as a structured barrier that prevents transepidermal water loss (TEWL) while simultaneously acting as a wetting agent to ensure uniform particle distribution.
Research
Clinical Evidence
High confidence0.6%
Key findings
- 01 Demonstrated significant reduction in the 'white cast' effect of inorganic sunscreens by improving pigment dispersion and surface tension.
- 02 Identified as a superior wetting agent at 0.2%–0.6% concentrations, enhancing the spreadability and tactile profile of aqueous formulations.

Dusting Analysis
Because it is effective at concentrations as low as 0.1%, it is rarely 'dusted' in the traditional sense; however, levels below 0.1% may fail to provide the functional pigment dispersion required for SPF products.
The Formula
Formulation
Stability
Exhibits excellent thixotropic behavior and maintains stability across extreme temperature and pH variations. Highly durable with a typical 36-month shelf life.
Synergies
- Zinc Oxide
- Titanium Dioxide
- Iron Oxides
Conflicts
- Highly polar solvents
- Strong oxidizing agents
Safety
Safety Profile
The large molecular architecture ensures the polymer remains on the skin surface without systemic absorption, making it non-toxic and non-sensitizing.
