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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Significant accumulation in organisms is not to be expected.
Key value for chemical safety assessment
Additional information
In contact with water, the acetic acid - boron trifluoride complex rapidly decomposes to acetic acid and boron trifluoride. Based on the log Kow of acetic acid (-0.17), bioaccumulation is not expected, and according to annex IX of Regulation (EC) No. 1907/2006 a study need not be conducted. Boron trifluoride dihydrate further hydrolyses, forming an acidic reactive mixture of boric acid, hydroxyfluoroboric acids, hydrofluoric acid, tetrafluoroboric acid and, depending on the pH value, the corresponding anions are produced. The hydrolysis products are all ionic species characterized by a low potential for bioaccumulation.
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.
