Science
Mechanism of Action
This anionic polymer significantly enhances a product's viscosity and water retention through its potent hydrophilic properties, attributed to its sulfonic acid groups. These characteristics facilitate excellent water absorption, which stabilizes emulsions and contributes to an aesthetically pleasing slip during application. It leaves the skin with a soft, plush after-feel, particularly when incorporated as a high molecular weight homopolymer.

Key findings
- 01 No specific human clinical studies demonstrating direct skincare benefits were identified. One in vitro study on a chick chorioallantoic membrane (CAM) assay showed dose-dependent inhibition of microvessel formation ranging from 10 to 150 micrograms/disc, indicating potential as an angiogenesis inhibitor.
