About

A long-chain behenyl (C22) quaternary ammonium conditioning agent with multiple hazard classifications including skin sensitization (H317), serious eye damage (H318), and aquatic toxicity (H400/H410).

A high-melting quaternary ammonium salt incorporating a behenyl (C22) fatty acid amide and a propyleneglycol-modified quaternary ammonium group. The behenyl chain provides exceptional substantivity and hydrophobic conditioning but the compound carries significant hazard classifications: H317 (may cause allergic skin reaction), H318 (causes serious eye damage), H400 (very toxic to aquatic life), H410 (very toxic to aquatic life with long-lasting effects) per CLP Regulation. These hazard classifications necessitate careful formulation controls. Not individually listed in EU Regulation 1223/2009 Annexes II or III but the GHS profile warrants caution.
