Additional information
Conclusion on classification
Classification justification according to CLP:
Based on the available data, N,N-dimethyldecanamide (CAS 14433-76-2) is considered to be rapidly degradable and has low potential for bioaccumulation. The short-term aquatic toxicity L(E)C50 are above 1 mg/L for fish, invertebrates and algae. Valid long-term toxicity data are available for algae, fish and daphnia. The lowest NOEC is 0.28 mg/L (thus in the rage of > 0.1 to < 1 mg/L) for aquatic invertebrates. Thus, the substance needs to be classified and labeled as environmental hazard Chronic Cat. 3 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 N,N-dimethyldecanamide (CAS 14433-76-2) 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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
