Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Substance is a gas and is extremely unlikely to reside in the aquatic or terrestrial compartment. Deriving a PNEC for a gas is unreasonable and technically of little use for risk assessment as the substance will not be present in the aquatic or terrestrial environment. Environment Canada conducted a review of 1-propene (Environment Canada 2014) and concluded that releases of propene to the environment occur almost exclusively to air.
Conclusion on classification
The lowest calculated acute result was a 96 hour EC50 for green algae of 12.1 mg/L. A measured log Kow of 1.77 for propene indicates the potential for bioaccumulation to be low. Measured data are not available to demonstrate that propene is readily biodegradable, but QSAR estimates indicate that biodegradation is expected to be rapid. In addition, propene is expected to partition to the air from water, further reducing the potential for exposure.
Taken together, the chronic and acute toxicity results do not support any environmental classification for acute or chronic hazard to the environment under CLP Regulations.
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.
