Expert Verdict

The monomer carries GHS warnings for skin irritation (H315), eye irritation (H319), and respiratory tract irritation (H335). In polymeric form used in cosmetics, risk is substantially lower - primary concern is residual monomer levels. Highly water-soluble cationic monomer (solubility >1,000 g/L); provides permanent positive charge to copolymers, enhancing wet-combing performance and frizz control
