Conclusion on classification

Classification justification according to CLP:

Based on the available data, l-Glutamic acid, N-coco acyl derivs., disodium salts (CAS 68187-30-4) is considered to be rapidly degradable and has low potential for bioaccumulation. The short-term aquatic toxicity L(E)C50 values are above 1 mg/L for fish, invertebrates and algae. Valid chronic toxicity data are available for invertebrates and algae – the lowest NOEC is above 1 mg/L for aquatic invertebrates. Thus, the substance does not need to be classified and labeled as environmental hazard according to the Regulation (EC) No.1272/2008 (CLP) and the Regulation (EU) No. 286/2011 (2nd ATP).

 

Classification justification according to DSD:

Based on the available data, l-Glutamic acid, N-coco acyl derivs., disodium salts (CAS 68187-30-4) is considered to be rapidly degradable and has a low potential for bioaccumulation. The short-term aquatic toxicity L(E)C50 values are above 1 mg/L for fish, invertebrates and algae. Thus, the substance does not need to be classified and labeled as environmental hazard according to Directive 67/548/EEC.
