Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary
Administrative data
Description of key information
Propene is a gas at standard temperature and pressure and is expected to partition primarily to air, therefore aquatic toxicity tests may not be relevant. Measured data are not available for propene for this endpoint. Due to the practical difficulties associated with the ecotoxicity testing of gases (i.e. maintaining exposure concentrations) the use of QSAR toxicity estimates is an appropriate alternative. Two QSAR models have been used to estimate the aquatic toxicity of propene, the Target Lipid Model and ECOSAR. The lowest values calculated by these two models have been used as the key value for assessment as below.
The lowest calculated freshwater fish 96-hour LC50 for propene is 43.3 mg/L.
The calculated 30 day ChV for freshwater fish is 5.3 mg/L.
The lowest calculated freshwater invertebrate (Daphnia) 48-hour EC50 for propene is 28.2 mg/L.
The estimated 16 day ChV for Daphnia is 3.1 mg/L.
The calculated freshwater algae 96-hour EC50 for propene is 12.1 mg/L and the 96-hour ChV is 4.5 mg/L.
The calculated IC50 for microorganisms was >207.4 mg/L.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
