Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EL10 and EL50 (16 h) > 10000 mg/L for Pseudomonas putida (ISO 10712).

Key value for chemical safety assessment

Additional information

One study, investigating the toxicity of Fatty acids, C16-18 (even numbered) and C18-unsatd., branched and linear, di- and triesters with trimethylolpropane (former CAS 85005-23-8) to Pseudomonas putida is available (Pateman, 1997). This cell multiplication inhibition test according to ISO 10712 determined EL10 and EL50 (16 h) > 10000 mg/L (WAF loading rate). No effects on the growth of Pseudomonas putida was observed at the tested concentration of 10000 mg/L. Furthermore, the biodegradation tests exhibit the readily biodegradability of the test substance. Thus, a disturbance in the biodegradation process of sewage treatment plant is not anticipated.
