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 genotoxicity according to CLP regulation Annex VI. It is therefore concluded that the reaction product of both substances is also not regarded as genotoxic.


Short description of key information:
Read across to ethanol (CAS No. 64-17-5)

Endpoint Conclusion: No adverse effect observed (negative)

Justification for classification or non-classification

No data is available for potassium ethanolate with respect to mutagenicity. However, as it rapidly hydrolyzes to form ethanol and potassium hydroxide, which are both non-mutagenic, it can be assumed that potassium ethanolate is also non-mutagenic. Hence, classification according to Regulation 1272/2008 (CLP) and Directive 67/548/EEC (DSD) is not warranted.
