Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Tert-butyl glycidyl ether is not readily biodegradable, not bioaccumulating, and highly soluble in water (WS: 90.3 g/L).

Based on the estimated log Kow of 0.97, the substance is expected to have low potential for adsorption to sediment and soil. In accordance with column 2 of REACH Annex VIII, the adsorption/desorption screening test has therefore not been conducted. Due to its physicochemical properties, tert-butuyl glycidyl ether will be present, remain, or distribute to, aqueous compartments, and will be degraded or metabolized there.

Additional information

Tert-butyl glycidyl ether (TBGE) was tested according to OECD 301F to be not readily biodegradable, therefore an assessment of the hydrolytic behaviour was conducted. In a read-across approach the experimental results of structurally similar substance n-butyl glycidyl ether are taken into account for the estimation of the hydrolysis rates of tert-butyl glycidyl ether. As a result of this approach the half-life for TBGE is estimated to 20.3 d (at pH 7) and 0.3 h at pH4. At pH 9 TBGE is considered to be hydrolytically stable (hydrolysis rate < 10 %).
