Endpoint summary
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.

Respiratory sensitisation
Endpoint conclusion
- Endpoint conclusion:
- no study available
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.
