Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

An OECD 307 aerobic soil transformation study (3 soils) was carried out with [1-14C]-Hexadecanamine (Harlan, 2010). Although this C16 amine is strongly sorbing to soil (median Kpsoil of 3875 L/kg at lowest measured concentration) half-lives between 8.1 and 9 days at 20 degree C were determined. The median Half-life of 8.9 d at 20 degree C corresponds to a median Half-life of 16.9 d at an environmental temperature of 12 degree C (see REACH Guidance).
