Conclusion on classification

In line with DSD (Directive 67/548/EEC) and EU-GHS (Regulation 1272/2008), which both refer to potential harmonized classification of L-arginine-HCl, L-arginine-HCl is not classified as dangerous for the environment (wording of DSD) nor does it fulfil the criteria relating to environmental hazards (wording of EU-GHS).
