Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

N,N-Dimethyldecan-1-amide (FADMA C10, 14433-76-2) itself has not been tested for acute invertebrate toxicity in the OECD 202 test.

However, OECD 202-results are available for a 50:50 mixture of FADMA C8 and FADMA C10, demonstrating an EC50 = 7.7 mg/l as well as for FADMA C12 showing to be more toxic, exhibiting an EC50 = 0.313 mg/l. Based on an interpolation between the shorter and the longer chain-length, i.e. by geometric mean of C8-10-FADMA and C12-FADMA data an EC50 = 1.55 mg/l has been deduced for FADMA C10 by read-across approach. This value is used for classification.

Additional information

A reliable GLP-study investigating the acute toxicity to daphnia magna of a mixture of the registered substance and a close homologue with a C8 instead of a C10 chain is available. The daphnia were exposed for 48h in a static system. The LC50 was 7.7 mg/L.

Results are read-across to the registered substance.
