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.

40 mg/L

Additional information

Tridecylamine, branched and linear (CAS 86089-17-0) is a mixture of C13 isomers (branched and linear; 99.8 -100%).

The assessment of the toxicity of Tridecylamine, branched and linear (CAS 86089 -17 -0) to aquatic microorganisms is based on the experimental data from a non-GLP short-term respiration inhibition test performed by BASF AG (1992; report no.: 92/1297/08/3) following OECD TG 209. Activated domestic sludge was used as inoculum. The 30-min EC50 was stated with ca. 40 mg/l (BASF AG, 1992, Rep. no. 407). In accordance to this in another study using non-adapted industrial sludge an EC50 of 46 mg/L was determined (nominal concentrations; BASF AG, 1983). The study was comparable to OECD TG 209.

Based on the experimental data, it can be concluded that depending on local conditions and existing concentrations, disturbances in the biodegradation process of activated sludge are possible.
