Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Experimental data are available to determine acute toxicity of diethylene glycol to fish.

A short-term study using Pimephales promelas was performed. The 96 -h LC50 value was measured to be beyond 75222 mg/L (nominal, analytically verified, Geiger, 1995). Additionally, the study performed by PTAC (2006) is also available. The short-term test was performed with Oncorhynchus mykiss. The 96 -h LC50 was determined to be 66000 mg/L (nominal, analytically verified).

These results are supported with the estimated value, wich was derived from a valid QSAR model (ECOSAR v2.0; BASF SE, 2022). The 96 -h LC50 for the substance was predicted to be 327224 mg/L. The substance is within the applicability domain of the model.

Overall, it can be concluded that based on the available experimental and estimated data the substance is with high probability acutely not harmful to fish.
