Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The adsorption coefficient Koc was estimated based on the pKa and the log Kow using a method according to Franco and Trapp (2008, 2009, 2010). The log Koc for the charged molecule was estimated to be 4.25 at pH 7. Therefore, adsorption to the solid soil phase is expected. However, octylamine is readily biodegradable (see ICULID Ch. 5.2.1).
The Henry's law constant value was calculated using the vapour pressure and water solubility. According to REACH Guidance, the HCL was corrected for the environmental relevant pH range. At pH 7 the HLC is estimated to be 8.25E-03 Pa*m³/mol.
Based on the Mackay Level I model, the uncharged substance will preferentially distribute into the compartments air (88.7%) and water (7.7%).
Regarding distribution in the environment, estimates obtained from Level III fugacity distribution modelling using US EPA EPI Suite v4.00, model component Level III fugacity model, indicate that emissions of n-octylamine will distribute predominantly into soil (77%) and water (20.4%). Significantly less proportions will distribute into air or sediment. The estimated persistence time is 343 hr (GUBDH, 2009).
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.
