Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
An assessment of the PBT status of dipropylene glycol against the criteria of Annex XIII has been made using all available data. The information available suggests that dipropylene glycol does not meet the PBT screening criteria as outlined in Annex XIII of Directive 2006/121/EC.
Persistence Assessment
A manometric respirometry test (OECD 301F) showed that dipropylene glycol is ready biodegradable. Therefore, dipropylene glycol can be regarded as not persistent.
Bioaccumulation Assessment
Based on the result of the octanol/water partition coefficient (Log Kow of -0.46) and from results of the bioaccumulation study with carp species, it is expected that dipropylene glycol has no bioaccumulative potential.
Toxicity Assessment
Experimental data on acute toxicity to aquatic organisms are available for dipropylene glycol. All acute L(E) C50values are much higher than the screening criterion of 0.1 mg/l. Dipropylene glycol is not classified as being a CMR substance and there is no evidence that dipropylene glycol is chronically toxic towards mammals. It can therefore be expected that dipropylene glycol is not toxic towards aquatic organisms.
Summary and overall Conclusions on PBT or vPvB Properties
The overall conclusions, based on the present available data, of the preliminary PBT assessment are that the (screening) criteria for PBT/vPvB are not met and that further testing in the scope of the final PBT assessment is not considered to be required.
- Likely routes of exposure:
Dipropylene glycol is not a PBT/vPvB substance, therefore the emission characterisation need not to be conducted.
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).
