About Potassium Stearate

Potassium Stearate is the potassium salt of stearic acid used primarily as an emulsifying agent in the production of detergents, foods, cosmetics, and other consumer goods. We also manufacture a full line of metallic stearates including calcium stearate, barium stearate, and zinc stearate. American Elements manufactures materials to many standard grades when applicable including Mil Spec (military grade), ACS, Reagent and Technical Grades; Food, Agricultural and Pharmaceutical Grades, Optical, Semiconductor, and Electronics Grades, and follows applicable USP, EP/BP, and ASTM testing standards. Most materials can be produced in high and ultra high purity forms (99%, 99.9%, 99.99%, 99.999%, and higher). Standard and custom packaging is available. Additional technical, research and safety (SDS) information is available. Please request a quote above to receive pricing information based on your specifications.

Elemental PotassiumSee more Potassium products. Potassium (atomic symbol: K, atomic number: 19) is a Block S, Group 1, Period 4 element with an atomic weight of 39.0983. The number of electrons in each of Potassium's shells is [2, 8, 8, 1] and its electron configuration is [Ar] 4s1. The potassium atom has a radius of 227.2 pm and a Van der Waals radius of 275 pm. Potassium was discovered and first isolated by Sir Humphrey Davy in 1807. Potassium is the seventh most abundant element on earth. It is one of the most reactive and electropositive of all metals and rapidly oxidizes. As with other alkali metals, potassium decomposes in water with the evolution of hydrogen because of its reacts violently with water, it only occurs in nature in ionic salts.Potassium Bohr Model In its elemental form, potassium has a silvery gray metallic appearance, but its compounds (such as potassium hydroxide) are more frequently used in industrial and chemical applications. The origin of the element's name comes from the English word 'potash,' meaning pot ashes, and the Arabic word qali, which means alkali. The symbol K originates from the Latin word kalium.
