Description of key information

The test substance itself (short name FADMA C10) has not been tested in the acute fish test (OECD 203). 


However, OECD 203-results are available for a 50:50 mixture of FADMA C8 and FADMA C10, demonstrating an EC50 = 14.8 mg/l as well as for FADMA C12 showing to be more toxic, exhibiting an EC50 >= 0.88 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 = 3.6 mg/l has been deduced for FADMA C10 by read-across approach. This value is used for classification.

Additional information

Three sufficiently reliable GLP-studies investigating the acute toxicity to fish of a mixture of the registered substance and a close homologue with a C8 instead of a C10 chain are available. All three studies exposed the fish for 96h in a static system.

Respective LC50 ranged from 14.8 to 21.1 mg/L. As all studies were of suffiecient reliability, the study with lowest LC 50 (Clariant 93.0432) was assigned as the key study.

Results are read-across to the registered substance.
