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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 test material was found to be unstable in water therefore formal testing was not possible. In accordance with the test guidance and after approval from the Sponsor, the Partition Coefficient was estimated using prediction software (KOWWIN v1.68).
The prediction software uses SMILES input to calculate the Partition Coefficient.
Result: Log P = -1.3 log units
Key value for chemical safety assessment
- Log Kow (Log Pow):
- -1.3
Additional information
The partition coefficient was estimated for both the test material TBA Clavulanate and the read across material potassium clavulanate as both test items were found to be unstable in water. Due to this a computer prediction was run the software programme (KOWWIN) v 1.68). The software uses the SMILES code to calculate the partition coefficient and came up with the following results:
TBA Clavulanate: -1.3
Potassium Clavulanate: -5.8.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
