Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 an adsorption/desorption 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 an adsorption screening 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 adsorption/desorption of the hydrolysis products have been assessed.

Boric acid:

Boric acid has a measured partition coefficient n-octanol/water (Log Pow) of -1.09. It can therefore be expected to have low potential for adsorption to soils or sediments.

Glycerol

Glycerol is considered to have low potential for adsorption to soils or sediments, based on a low partition coefficient (log Pow) and predicted log Koc values.

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.
