Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
In soil, the acetic acid - boron trifluoride complex reacts readily with the moisture to form acetic acid and boron trifluoride dihydrate.
Acetic acid has been determined to be readily biodegradable under aerobic and anaerobic conditions. The half-life of acetic acid in soil has been reported to be ≤2 days at 60% of MWHC (Nowak and Nowak, 1990). If first-order degradation is assumed then the half-life of acetic acid would be ≤ 0.6 days (DT50 ≤ 14.45h). Additionally, acetic acid is highly soluble. Acetic acid does not pose a significant terrestrial toxicological risk.
Boron trifluoride dihydrate is not readily biodegradable, but has a low potential for adsorption. Boron trifluoride dihydrate, as well as its further hydrolysis products (e.g. boric acid, fluoroborates), is inorganic and has no cationic properties. Binding to sewage sludge is therefore unlikely, and as a consequence a transfer to the soil compartment is not expected. No tests on terrestrial organisms are therefore provided.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.
