Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Read across to ethanol (CAS No. 64-17-5)
Key value for chemical safety assessment
Additional information
Potassium ethanolate is a salt only stable when humidity is excluded. In contact with water the substance reacts violently and forms ethanol and potassium hydroxide. Both substances are not classified regarding repeated dose toxicity according to CLP regulation Annex VI. It is therefore concluded that the reaction product of both substances is also not regarded as toxic after repeated exposure.
Justification for classification or non-classification
No data is available for potassium ethanolate with respect to repeated dose toxicity. However, as it rapidly hydrolyzes to form ethanol and potassium hydroxide, which are both non-toxic after repeated exposure, it can be assumed that potassium ethanolate is also non-toxic. Hence, classification according to Regulation 1272/2008 (CLP) and Directive 67/548/EEC (DSD) is not warranted.
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.
