Science
Mechanism of Action
Creates flexible, uniform films on the skin surface that provide water-resistant protection while utilizing hollow sphere light-scattering technology to extend UV photon path length, thereby amplifying the effectiveness of existing UV filters
Research
Clinical Evidence
High confidence1%
Key findings
- 01 1% concentration demonstrated 11-18% increase in SPF value through hollow sphere UV scattering technology
- 02 26-28% concentrations in aqueous dispersions showed stable film-forming properties without significant skin penetration

Dusting Analysis
This functional polymer is used at effective concentrations rather than trace amounts for marketing purposes
The Formula
Formulation
Stability
Supplied as aqueous emulsion with 30-60% solids content; mechanically stable but sensitive to pH extremes and high electrolyte concentrations which may cause flocculation
Synergies
- UV filters for SPF enhancement
- Water-resistant formulation components
Conflicts
- High concentrations of electrolytes/salts
- Cationic surfactants
- Strongly acidic environments below pH 5.0
Safety
Safety Profile
35% maximum applies to nail products; leave-on skin products typically use under 5%; insufficient data for nano-sized versions in leave-on products at 0.06%
