EC number: 701-042-9 | CAS number: -
EC50 (3 h) was stated as > 10000 mg/L (nominal, OECD 209)
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.
