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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Although not required as this is an inorganic substance, an end point has been derived in Cordia JA et al. (2003).
Key value for chemical safety assessment
- Log Kow (Log Pow):
- -1.09
- at the temperature of:
- 22 °C
Additional information
The log partition coefficient n-octanol/water (Log Pow) of boric acid was reported to be -1.09 ± 0.16 (22 ± 1 ºC), pH 7.5. It is anticipted that if Orthoboric acid, potassium salt could be isolated from the chemical matrix from which it is made, it would exhibit essentially the same Log Pow value since, in a water environment, this salt would exist in equilibrium with boric acid, and boric acid will be the most abundent species present under these circumstances.
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.
