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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
QSAR estimation.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- -4.62
Additional information
No data is available because Perchloric acid is an inorganic substance. However, in order to be able to use CHESAR for the exposure assessment, a conclusion should be provided for the CSA. So, a Kow value can be calculated by QSAR model. Although inorganic compounds are outside the applicability domain of the EPISUITE model, this model is the most relevant for this endpoint and therefore it is used to estimate a Kow value of perchlorate as reported below.
KOCWIN v2.00 result estimation for:
- perchloric acid (SMILES : O=CL(=O)(=O)O)
Estimated logKow =- 4.62.
- sodium perchlorate (SMILES : O=CL(=O)(=O)O([Na]))
Estimated logKow =- 7.17.
This estimated logKow value is consistent with the conclusion of no bioaccumulation based on measured BCF and of low adsorption onto soil and sediment.
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.
