Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

There is chronic toxicity data on two of the three constituents of this substance (those that represent the structural extremes.) QSAR data suggests that the toxicity decreases with increasing molecular weight and therefore that monoethylene glycol (MEG) is likely to be the most toxic species. The experimental data on MEG is a 7 day study in Ceriodaphnia, which can be considered a reliable chronic study. Overall, it is clear that all of the components present very low chronic toxicity.
