Science
Mechanism of Action
This crosspolymer utilizes a unique structure of long-chain fatty alcohols (C22 behenyl and octyldodecyl) crosslinked with citrate to create a 'second skin' matrix. This biomimetic film anchors to the stratum corneum, effectively sealing in moisture while offering significant water and sweat resistance without a greasy finish.
Research
Clinical Evidence
High confidence3%
Key findings
- 01 Clinical evaluation demonstrated up to 80 minutes of sustained water resistance in both oil-in-water and water-in-oil emulsions.
- 02 Technical testing confirms a measurable reduction in Trans-Epidermal Water Loss (TEWL) due to the formation of a substantive, long-lasting barrier.
Transparency
Dusting Analysis
Because it acts as a functional texture enhancer and water-proofing agent, concentrations below 0.5% are typically insufficient to provide the intended barrier-repair or water-resistance benefits.
The Formula
Formulation
Stability
Possesses a high melting point which enhances the thermal stability of emulsions; it also prevents the 'white-out' effect common when applying creams to damp skin.
Synergies
- Mineral UV filters
- Ceramides
- Glycerin
Conflicts
- Formulations with pH above 8.0 (risk of ester bond hydrolysis)
- Low-shear processing environments
Safety
Safety Profile
While the specific polymer is awaiting CIR review, its constituent building blocks—citric acid, propanediol, and fatty alcohols—are well-documented as safe and non-irritating.
