Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Short description of key information:

The in vitro genetic toxicity tests indicated no evidence of mutagenic activity. In addition, both the in vitro and the in vivo genetic toxicity tests with the structurally related sodium hydroxide indicated no evidence of mutagenic activity. According to the REACH Regulation, further in vivo mutagenicity studies shall only be considered in case of a positive result in genotoxic (in vitro) studies (column 2, Annexes VII, VIII). Therefore, further in vivo testing for mutagenicity is not relevant for potassium hydroxide.

Moreover, it is technically not feasible to perform genotoxicity tests at physiological pH with KOH.
