Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

From the water surface the substance will not evaporate into the atmosphere.

Key value for chemical safety assessment

Additional information

Due to the rapid hydrolysis of sodium ethanolate in water or soil moisture, the relevant species subject to environmental distribution are the degradation products sodium hydroxide and ethanol. For the sodium hydroxide it was concluded that it will be found predominantly in the aquatic compartment as alkali metal and hydroxide ions and will not adsorb on particulate matter or surfaces. For ethanol the Henry’s law constant of 0.575 Pa m3/mol was calculated using HENRYWIN v3.20. From this result it can be concluded that the substance will not evaporate from the water surface to the atmosphere.
