Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Abiotic degradation is not a relevant pathway in the environmental fate of 2-(1-methylethoxy)ethyl acetate (CAS 19234-20-9). Evaporation from the water phase in relevant amounts is unlikely based on the Henry’s Law constant (< 1 Pa m³/mole (HENRYWIN v3.20); Corti, 2011). The vapour pressure of 700 Pa indicates a potential for volatilization. However, the substance is susceptible to undergo rapid indirect photodegradation in air (DT50 < 24 h). Therefore, accumulation in air and the subsequent transport to other environmental compartments is not expected. The estimated half-lives for abiotic hydrolysis are > 24 h at pH 7 and pH 8, indicating that significant hydrolysis is not expected to occur in natural waters.
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.
