Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The adsorption potential to soil or sediment is low. The mean logKoc = -0.575 (and can not be displayed in the field below).
Key value for chemical safety assessment
- Koc at 20 °C:
- 0.266
Additional information
The partition coefficients of L-aspartic acid is low, i.e. log Pow -3.89. L-aspartic acid is readily biodegradable. A relevant adsorption of L-aspartic acid to soil is therefore not expected and a waiving of the study and of further studies on adsorption is justified.
Applying additionally a recognised QSAR models it was calculated that the log Koc of L-aspartic acid is low, i.e. 0.87 with one method and -2.02 with another method, see a separate endpoint record.
The geometric mean of the 2 available Koc was calculated according to the ECHA Guidance Documents on Info Requirements, R.7.1.15.3 to logKoc = -0.575, corresponding to Koc = 0.266. The adsorption potential to soil or sediment is therefore low.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).
