It appears as a white to off-white solid and is highly soluble in polar solvents such as ethanol and other alcohols, while being less soluble in non-polar solvents. This compound is hygroscopic, meaning it readily absorbs moisture from the air, which can lead to hydrolysis and the formation of potassium hydroxide and ethanol.
