Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 accordance with EC 1907/2006, Annex VIII, point 9.2.2.1, column 2, hydrolysis as a function of the pH is not required since B-TTEGME is readily biodegradable, as shown in study section 4.1.2.1.2.
B-TTEGME contains 50% of the borated glycol ester B-TEGME and two other borated glycol esters at quantities of 40% (B-TetraEGME) and 10% (B-PentaEGME). All components of B-TTEGME are homologue esters. Ester bonds are cleaved by hydrolysis. Experimental evidence for spontaneous hydrolysis of the ester bond is available for B-TEGME. Hydrolysis of B-TEGME as a function of the pH confirms B-TEGME is not stable in water: B-TEGME was hydrolysed spontaneously and immediately after contact with water pH 1.4, 4,7 and 9. This result is considered representative for the hydrolytic behaviour of the other two borated glycol esters of B-TTEGME, i.e., it is concluded that B-TTEGME is hydrolysed spontaneously after contact with water at the above pH values.
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.
