Stearic Acid
Stearic acid, a saturated fatty acid with the chemical formula C-18, is a prominent component in various industrial applications due to its unique properties and versatility. Typically derived from the separation and hydrogenation of fats, commercial stearic acid often exists as a mixture with palmitic acid (C-16), resulting in a solid form at room temperature that exhibits a distinct fatty character. As one of the most common saturated fatty acids found in nature, stearic acid plays a crucial role in numerous manufacturing processes.
In the industrial sector, stearic acid is extensively utilized in the production of candles, surfactants, and fatty alcohols, making it essential in everyday products. Its applications extend to the rubber, lubricant, and textile industries, where it contributes to the formulation of EBS waxes, fatty amines, and paper chemicals. Notably, AsiaPalm has leveraged the properties of stearic acid for the production of metal soaps and additives specifically designed for the plastics industry.
