Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 reference substance hydrolyses within less than an hour to its hydrolysis products; Boric acid and glycerol. Therefore, conducting a ready biodegradation study on the reference substance is not feasible.
Key value for chemical safety assessment
Additional information
The reference substance hydrolyses within less than an hour to its hydrolysis products; Boric acid and glycerol. Therefore, conducting a ready biodegradation study on the reference substance is not feasible. If a study were conducted it would give a result representative of the hydrolysis products mentioned above.
The biodegradation of the hydrolysis products, boric acid and glycerol have been assessed.
Boric acid
A ready biodegradation study is not relevant for boric acid as it is an inorganic compound and not degradable. It is not subject to hydrolysis, photodegradation or biodegradation.
Glycerol
Glycerol is considered to be readily biodegradable.
Refer to section 13, Ecotoxicological expert report (BAGE: Evaluation of Environmental Fate and Ecotoxicity Properties) for further details of the evalaution of ecotoxicological properties of the reference substance and its hydrolysis products, especially for additional information on glycerol.
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.
