Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

One key study was available using the read-across substance glycerol as test substance. No effects were seen at 10000mg/L.

Key value for chemical safety assessment

EC50 for microorganisms:
10 000 mg/L

Additional information

The toxicity threshold was determined for a number of chemicals using Pseudomonas putida. The toxicity threshold (comparable to a NOEC) in a 16 hour study was > 10000 mg./L. While this study does not follow the typical activated sludge respiration inhibition study design, it does demonstrate that glycerol is relatively non-toxic to bacteria.
