Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
There are several studies available which demonstrate rapid biodegradation of n-octylamine in water. The two most important studies are summarized below. Simulation studies on biodegradation in surface water, sediment or soil are not available. Due to the ready biodegradability of n-octylamine, these studies are not required.
Within the reliable key study (pre-guideline, comparable to OECD TG 301-C, i.e. MITI-I), biodegradation of n-octylamine (test substance: HCl salt of octylamine, see read-across document IUCLIDsection 13) was examined in a test for ready biodegradability. The BOD accounted for approx. 65% of the ThOD (theoretical oxygen demand) after 5 days, and for approx. 73% after 12 days of culture. N-octylamine is therefore considered to be readily biodegradable fulfilling the 10-day window requirement (Yoshimura et al., 1980).
This is supported by another reliable study demonstrating ready biodegradability of octylamine (BASF AG, 1997; Report No. 96/0345/21/1) according to OECD 301A, using domestic activated sludge as inoculum. The degradation reached 99% after 11 d, the 10 -d window was kept.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
