About
A polymer-bound benzotriazole UV absorber. Because the UV-active group is locked to a polymer chain, it cannot penetrate skin, addressing concerns about free benzotriazoles.
Function
Skin benefits
- Polymeric UV absorber
- Bound to polymer backbone — non-bioavailable
- Photo-stabiliser for sunscreen formulas
Known concerns
- Methacrylate polymer — residual monomer is the only realistic concern
- Limited cosmetic-specific dossiers
- Polymer-bound benzotriazoles are an emerging-data category
