Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Only one valid ready biodegradability test result for N-[3-(tridecyloxy)propyl]-1,3-propane diamine,branched monoacetate and N-[3-(tridecyloxy)propyl]-1,3-propane diamine branched is available because these substances are extremely toxic to micro-organisms. N-[3-(tridecyloxy)propyl]-1,3-propane diamine,branched monoacetate and N-[3-(tridecyloxy)propyl]-1,3-propane diamine branched did not cause a reduction in the endogenous respiration in the presence of 16 mg/L of humic acid. N-[3-(tridecyloxy)propyl]-1,3-propane diamine,branched monoacetate and N-[3-(tridecyloxy)propyl]-1,3-propane diamine branched was biodegraded 8% at day 28 in the Closed Bottle test. In the prolonged Closed Bottle test (enhanced biodegradability testing) a biodegradation percentage of 63 was achieved at day 60. Hence this substance should be classified as not persistent.
