Stearic acid is a saturated fatty acid with higher hydrocarbons and it’s usually called as Octadeconic acid. Stearic acid is one of the most common saturated fatty acids found in nature and occurs in many animal and vegetable fat oils. It is a waxy white solid with chemical formula of CH3(CH2)16CO2H and molar mass of 284.48 g/mol. Stearic acid can be obtained from the hydrogenation of unsaturated vegetable oils. Stearic acid is actually a mix of stearic acid, palmitic acid and oleic acid. Stearic acid is available in different grades in the market, such as rubber grade, candle grade, double pressed grade and triple pressed grade. The many grades differ on the basis of iodine number, saponification value, acid number and the fatty acid composition.
