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.
Key value for chemical safety assessment

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.
