Science
Mechanism of Action
This crosspolymer forms a rigid, three-dimensional microscopic network that functions as a leach-resistant barrier. On the skin's surface, it develops a continuous film that smooths irregularities, improves sensory feel, and ensures that encapsulated materials remain isolated from the dermal layers.
Research
Clinical Evidence
High confidence9.5%
Key findings
- 01 Demonstrated as an effective solid matrix for pigment entrapment at 9.5% to ensure zero skin penetration in body paint applications.
- 02 Identified as a versatile structure-forming agent in skin and hair treatments between 0.01% and 30% for moisture retention.

Dusting Analysis
Because it is often used as a carrier for other ingredients (like glitters or neon pigments), its concentration is usually determined by the specific pigment load required rather than cost-saving 'dusting' practices.
The Formula
Formulation
Stability
The polymer is chemically inert in finished goods but requires a stable pH range; it is insoluble in water and remains stable unless exposed to extreme acidic conditions.
Synergies
- Fluorescent dyes
- Specialty pigments
- Lipophilic actives
Conflicts
- Strong oxidizing agents
- Strong acids
- High concentrations of anionic surfactants
Safety
Safety Profile
Safety is contingent on the polymer remaining intact; strong acids may trigger the release of residual formaldehyde, a known sensitizer. Currently compliant under EU Regulation 1223/2009 for solid matrix forms.
