Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
Persistence
Diisopentyl ether is considered as hydrolytical stable and is not ready biodegradable. Therefore, based on the data currently available, diisopentyl ether is considered as potentially persistent in the environment as a worst-case assessment.
Bioaccumulation
Based on results from a valid fish bioconcentration study the substance is considered to not fulfil the B criteria for PBT assessment.
Toxicity
The measured acute L(E)C50 values in studies with fish, daphnids and algae are higher than the screening criterion of 0.1 mg/l. It can therefore be expected that diisopentyl ether does not fulfill the criteria for aquatic toxicity. Diisopentyl ether is not classified as being a CMR and there is no evidence that it is chronically toxic towards mammals. Therefore diisopentyl ether is not assigned as toxic.
Overall conclusion on PBT assessment
Although the criteria for P or vP are met, diisopentyl ether is not B/vB or T. Therefore, overall the substance may be considered as not PBT/vPvB.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
