Potassium stearate may be prepared by saturating a hot alcoholic solution of stearic acid with alcoholic potash. [3]
The compound forms colorless crystals.
Slightly soluble in cold water, soluble in hot water, ethanol, insoluble in ether, chloroform, carbon disulfide. [4] A component of liquid soap.
The compound is primarily used as an emulsifier in cosmetics and in food products. It is also used as a cleansing ingredient and lubricant. [5] [6]
Causes skin irritation and serious eye irritation. [7]
