Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 (3 h) was stated as > 10000 mg/L (nominal, OECD 209)

Key value for chemical safety assessment

Additional information

One study, investigating the toxicity offatty acids, C16-18 even numbered and C18-unsatd. triesters with propylidynetrimethanol (CAS 57675-44-2) to activated sludge microorganisms is available. This respiration inhibition test (Kuttler, 1997) with activated sludge (domestic) according to OECD 209 showed an increase of respiration rate about 20% at the tested concentration of 10000 mg/L (nominal) in comparison to the control. No inhibition of respiration rate was observed. Therefore the EC10 and EC50 (3 h) was derived as > 10000 mg/L (nominal). 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.
