Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Hydrolysis is not a relevant degradation pathway.

Key value for chemical safety assessment

Additional information

No experimental data evaluating the hydrolysis of Disodium N-lauroyl-L-glutamate are available. However, according to Regulation (EC) No. 1907/2006, Annex VIII, column 2 (, testing hydrolysis as a function of pH is not required since the substance is readily biodegradable.

Nevertheless, most amides hydrolyze to acids extremely slowly under environmental conditions with half-lives measured in centuries. Electronegative groups on carbon or nitrogen greatly accelerate base catalyzed hydrolysis, but alkyl groups on nitrogen retard both acid and base catalyzed processes (Mabey and Mill, 1978). Thus, hydrolysis is not considered to be a relevant degradation pathway for Disodium N-lauroyl-L-glutamate in the aquatic environment.
