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 (9.2.2.1), 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.
