Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Peer-reviewed literature.

Key value for chemical safety assessment

Half-life in soil:
30 d
at the temperature of:
20 °C

Additional information

10% mineralisation after 24 hours at 15°C.

Assuming first order degradation kinetics and a DT90 of maximum 100 days, the estimated DT50 for lysine is 30 days.

The data provided here is for lysine, but the information can be used for L-lysine HCl. It is not expected that the HCl group will have an influence on adsorption and biodegradability of the substance.
