Endpoint summary
Administrative data
Description of key information
No studies on skin sensitization with potassium propan-2-olate are available. According to the REACh Regulation (EC) No 1907/2006, Annex VII, column 2 point 8.3 a study on skin sensitization does not need to be conducted if the substance is classified for skin corrosion. The test substance is classified as skin corrosive based on the available information and is used as a transported intermediate. According to REACh regulation 1907/2006, Article 18, further testing is not required.

Justification for classification or non-classification
In contact with water the substance hydrolyses rapidly and forms n-butanol and potassium hydroxide. These two hydrolysis products are both not classified as skin sensitizer according to Annex VI of the CLP regulation (EC) No 1272/2008.
Thus a classification of the substance for sensitizing potential 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.
