Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

Adequate screening-level data are available to characterize the environmental hazard for the purposes of the REACH dossier. Hexylene glycol is readily biodegradable and all acute aquatic toxicity tests indicate LC50/EC50 higher than 1 mg/L. In addition, the available long-term 72h-NOEC for algal growth rate inhibition is also above 1 mg/L. Finally, log Kow of hexylene glycol is lower than 4.

Therefore, hexylene glycol is not considered dangerous for the environment according to criteria of CLP regulation EC 1272/2008.
