Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC50 (16 h) > 10000 mg/L for Pseudomonas putida (DIN 38412)

Key value for chemical safety assessment

Additional information

One study, investigating the toxicity of Fatty acids, C8-10 (even), C14-18 (even) and C16-18 (even)-unsatd., triesters with trimethylolpropane (former CAS 85186-89-6) to Pseudomonas putida, is available (Clemes, 1996). This cell multiplication inhibition test according to DIN 38412 determined an EC10 and EC50 (16 h) > 10000 mg/L (nominal). No inhibition on the growth of Pseudomonas putida was observed at the tested nominal concentration of 10000 mg/L (clearly above the water solubility (< 1 mg/L)). Furthermore, the biodegradation tests exhibit the readily biodegradability of the test substance. Thus, a disturbance in the biodegradation process of a sewage treatment plant is not anticipated.
