Overview
Caustic Potash — potassium hydroxide (CAS 1310-58-3) — is a white, deliquescent alkali we supply in flake or pellet form for applications where potassium, rather than sodium, is the preferred alkali metal. It's used in liquid and potassium soap manufacture, as a battery electrolyte, for general pH adjustment and neutralisation, and as the catalyst in biodiesel transesterification. We pack it in 25/50 kg moisture-proof HDPE-lined bags and drums to protect it from atmospheric moisture in transit and storage.
