Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
In accordance with point 9.3.1 and 9.3.3, Column 2 (Specific rules for adaptation) of Annex VIII of Regulation (EC) No. 1907/2006, adsorption/desorption screening is not required if the substance has a low potential for adsorption and its relevant degradation products decompose rapidly. The ready biodegradability of the substance (sodium 5-oxo-DL-prolinate) was determined as 74.4 % after 28 days. Furthermore the substance has a very low log Pow and hence has a low potential for adsorption. On this basis, adsorption/desorption testing has been omitted.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
