Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 substance was determined not to be readily biodegradable and attained 3% degradation after 28 days in a study conducted to EU Method C.4-E (closed bottle test). In an inherent biodegradability study conducted to OECD method 302C, the substance was shown to undergo 43 % biodegradation after 48 days in the test conditions. Biodegradation started on day 3 and reached a plateau at about 40 % on day 11.
The estimation software gives a Koc value for the substance of 24.97 equivalent to log Koc 1.397. The substance's high water solubility and relatively low log Pow indicate that bioaccumulation testing would not be required.
The hydrolytic stability of the test material was investigated, as a function of pH, in a study conducted to EU Method C.7 and OECD 111. The half-lives of the test material at 25°C were estimated to be 388 days at pH 4, > 1 year at pH 7, and 11.4 days at pH 9.Based on the chemical structure of the test material, hydrolysis was considered to have occurred at the ester functional group, the hydrolysis products being 1,3-dioxolane-2-acetic acid, 2-methyl and ethanol.
Environmental exposure to the substance is anticipated to be extremely widespread and diffuse.
Additional information
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.
