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

The hazard assessment of Sodium hydrogen N-(1-oxododecyl)-L-glutamate (CAS No. 29923-31 -7) reveals that

     aquatic invertebrates are more sensitive organisms than fish.

     Nevertheless a chronic test on Daphnia Magna (Reproduction test) was

     performed according to OECD 211. Values obtained were LOEC 2.50 mg/l and

     NOEC 1.25 mg/l.Given the very fast biodegradation of the substance in

     the environment ( 80% in 7 days) and the very low bioaccumulation

     potential (log Kow = -1.33) chronic toxicity of the substance is not

     indicated. In addition, an exposure assessment performed using PNECs

     derived on the basis of the available aquatic short-term toxicity tests

     (including a conservative assessment factor of 1000) indicate no risk

     for the aquatic environment.
