Administrative data
Description of key information
The substance hydrolyses rapidly in contact with water. The hydrolysis product potassium hydroxide (CAS No. 1310-58-3) is classified with skin corrosion Category 1A according to CLP regulation 1272/2008 Annex VI. In addition, the analogous products potassium tert butylate (CAS No. 865-47-4) and potassium tert-amylate (CAS No. 41233 -93 -6) are both classified with skin corrosion Category 1A based on in vivo and in vitro data, respectively.

Additional information
Justification for classification or non-classification
The substance hydrolyses rapidly in contact with water. The hydrolysis product potassium hydroxide (CAS No. 1310-58-3) is classified with skin corrosion Category 1A according toCLP regulation 1272/2008 Annex VI. In addition, the analogous products potassium tert-butylate (CAS No. 865-47-4) and potassium tert-amylate (CAS No. 41233 -93 -6) are both classified with skin corrosion Category 1A based on in vivo and in vitro data, respectively.
Thus potassium n-butylate is classified with skin corrosion Category 1A.
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.
