Science
Mechanism of Action
This copolymer creates an ultra-thin, non-permeable barrier on the skin's surface. By encapsulating pigments—specifically fluorescent or neon dyes—it prevents direct contact between potentially irritating colorants and the epidermis, while simultaneously enhancing water resistance and color longevity.

Clinical Evidence
Medium confidence5%
Key findings
- 01 Research indicates its primary efficacy lies in pigment encapsulation (e.g., DermaGlo technology), ensuring dyes remain on the surface without dermal penetration.

Dusting Analysis
As a functional resin rather than a bioactive, 'dusting' is less of a concern; however, concentrations below 0.1% are unlikely to provide meaningful film-forming or pigment-shielding benefits.
The Formula
Formulation
Stability
Highly resilient across a broad pH spectrum, making it ideal for diverse environments including high-pH hair treatments.
Synergies
- Fluorescent pigments
- Hydrophobic UV filters
Conflicts
- Strong polar solvents
- High concentrations of anionic surfactants
Safety
Safety Profile
Rated as low hazard (Score 1) by EWG. FDA restrictions apply to the pigments it carries, specifically regarding use in the immediate eye area.
