Potassium Stearate Description
Potassium Stearate is the potassium salt of stearic acid and belongs to the category of alkali-metal soaps. It is generally supplied as a white to off-white powder, granule, flake or solid material with a mild characteristic fatty or soap-like odour.
Chemically, Potassium Stearate is represented as C₁₈H₃₅KO₂ and is also known as Potassium Octadecanoate or Stearic Acid Potassium Salt. Commercial Potassium Stearate may not always consist exclusively of a single pure stearate molecule.
Natural and commercial stearic-acid feedstocks often contain both stearic acid and palmitic acid. The resulting material may therefore contain potassium palmitate and other closely related potassium fatty-acid salts.
