Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Diisopropyl ether has a very high volatility and low Log Pow . Consequently, also the Log Koc is low and adsorption to soil is not significant. As a result, uptake of diisopropyl ether via roots of plants is negligible. Uptake via leaves (of vapours) also could be imagined but as a supporting study with diethyl ether (Christ, 1996) showed no effect at concentration high as 100 g/m3 at 3h of exposure and exposure assessment showed such concentration in biotic environment to be unrealistic, an additional study on terrestrial plants is not required. The publication of Christ 1996 is scientifically solid and was performed on 7 different plants but had to be rated Klimisch 3 as it did not reference to any guidelines.

Key value for chemical safety assessment

Additional information

A study on terrestrial plants is not proposed by the registrant as the chemical assessment does not indicate a need to investigate further effects on terrestrial plants. This is based on the knowledge that the substance has a low bioaccumulation potential and as outlined in the section on environmental fate, the substance due to its low water solubility and high vapour pressure will volatilise rather quickly from the aqueous environment or soil and becomes abiotically degraded in air very quickly (half-life < 1day). Hence, significant exposure of terrestrial plants is not of concern.
