Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The half-life value of 17 days is used for the C12-C14-1,3-diaminopropane based on read-across from the structurally related hexadecyl amine.

Key value for chemical safety assessment

Half-life in soil:
17 d
at the temperature of:
12 °C

Additional information

The substance is readily biodegradable, thus there is no requirement for performing a soil biodegradation test. For14C-hexadecyl amine the half-life in soil according to OECD 307 was 8.13 - 8.98 days at 20 °C. Using EUSES this half-life is recalculated to 17 days at 12°C. As both the primary alkyl amine and diamines are readily biodegradable and have an almost identical observed sorption to soil, the half-life of hexadecylamine in soil is considered to be representative for the C12-C14-1,3-diaminopropanes as well. Thus for this diamine a half-life value of 17 days is used based on read across.
