How to distinguish between calcium stearate and stearic acid products


How to distinguish calcium stearate from stearic acid products? Many people mistakenly believe that calcium stearate and stearic acid products are chemical. Although there is only a word difference, their performance is vastly different. Calcium stearate is a vital chemical product in industrial production, mainly used as a lubricant and mold release agent. What is acid? In chemistry, acids refer to compounds whose cations are completely hydrogen ions when ionized in solution and can make the purple litmus test solution turn red. In a narrow sense, they can also be divided into inorganic acids and organic acids. According to the acid-base proton theory, acids can release protons, collectively known as acids. Stearic acid is an organic acid that has a certain amount of acidity, and what loses the combination of hydrogen and metal calcium ions is calcium stearate. Stearic acid is a white or almost white powder or crystalline hard lump with a smooth feeling, and its profile has a slight luster of fine needle-like crystals; It has a slight odor similar to oil and is odorless. Calcium stearate is a white powder that is insoluble in water, cold ethanol, and ether, soluble in organic solvents such as hot benzene, benzene, and turpentine, and slightly soluble in hot ethanol and ether. When heated to 400 , it slowly decomposes and is flammable. When it encounters strong acids, it decomposes into stearic acid and corresponding calcium salts, with hygroscopicity. Stearic acid is used in two skincare products, snow cream and cold cream, to emulsify and make it a stable and white paste. Stearic acid is the primary raw material for making almond honey and milk. Stearic soap esters are more widely used in the cosmetics industry.
