Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data

Description of key information

Data waiving according to ANNEX VII, column 2 of the REACH regulation: the available information regarding skin corrosion indicate that the criteria for classification as corrosive for the skin are met.

Key value for chemical safety assessment

Skin sensitisation

Endpoint conclusion
Endpoint conclusion:
no study available
Additional information:

A study on the skin sensitisation potential does not need to be conducted according to Annex VII, Section 8.3, Column 2 of the REACH regulation, as potassium methanolate is classified as corrosive to the skin. However, the available data on the skin sensitisation potential of the hydrolysis products potassium hydroxide (CAS No. 1310-58-3) and methanol (CAS No. 67-56-1) were taken into account for classification and labelling purposes (please refer to the endpoint summaries of methanol and potassium hydroxide for more details). According to the OECD SIDS for sodium and potassium methanolate (OECD, 2006) the data on the hydrolysis products suggests that potassium methanolate is not expected to have a skin sensitisation potential.

Justification for classification or non-classification

There are no data available on the skin sensitisation potential of potassium methanolate. Potassium methanolate is classified as corrosive to the skin according to Annex VI of the CLP regulation (EC 1272/2008), therefore no additional data on the skin sensitisation potential of potassium methanolate is necessary according to Annex VII, Section 8.3, Column 2 of the REACH regulation. For classification and labelling purposes, the available data of the hydrolysis products (potassium hydroxide and methanol) were taken into account.The available data on the hydrolysis products are conclusive but not sufficient for classification.
