Stability
Specific data on the optimal pH range for stability is not available, although methacrylate-based polymers are known to exhibit pH-sensitive behavior in various applications.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not specifically evaluated POLY(BENZOTRIAZOLYLHYDROXYPHENETHYL METHACRYLATE). While methacrylate monomers are recognized sensitizers and irritants, this ingredient is a polymer, which is generally anticipated to be significantly less reactive. Other methacrylate polymers, such as Polymethyl Methacrylate (PMMA), have been deemed safe in cosmetic formulations.
