Description of key information

Potassium hydroxide is mainly manufactured as a solution but solid KOH is also placed on the market. The particle size of pearls and flakes is very large and therefore there will be virtually no particles < 100 µm. Dust formation is unlikely because of the hygroscopic properties. Furthermore KOH has a negligible vapour pressure and is rapidly neutralized in air by carbon dioxide and therefore dust and vapour exposure are not expected.
