Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Dipropylene glycol is capable of being degraded under aerobic conditions by bacteria in water. Results from biodegradation screening tests show that dipropylene glycol is readily biodegradable in water (>80% after 28 days) (West et al., 2007). Significant biodegradation (>20%) was found in a simulation test with natural seawater after 64 days (West et al., 2007). Therefore dipropylene glycol is not expected to persist in water or marine environments. Simulation studies with sediment and/or soil are not available.
The rate constants used in the assessment are (calculated with EUSES):
Degradation in the STP |
24 d-1 |
Biodegradation in water |
0.0462 d-1 |
Biodegradation in sediment |
2.31E-03 d-1 |
Biodegradation in soil |
0.0231 d-1 |
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.
