Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A GLP-study according to OECD Guideline 111 is available for dipropylene glycol methyl ether acetate.
Key value for chemical safety assessment
- Half-life for hydrolysis:
- 0.03 d
- at the temperature of:
- 323 K
Additional information
The preliminary test for abiotic degradation showed that the compound was stable to hydrolysis in buffers with pH values of 4.0 and 7.0 for 5 days at 50ºC, but degraded at pH 9.0. The advanced test for abiotic degradation was conducted at 50ºC and 37ºC at pH 9.0. The rate constants at 50ºC and 37ºC were calculated to be 2.69 x 10-2h-1and 7.52 x 10-3h-1respectively. The half-lives were calculated to be 25.8 h at 50ºC and 92.1 h at 37ºC.
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.
