Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
