Applications

Applications of stearic acid are varied and cover many industrial and domestic sectors. It serves as an activator in the vulcanization accelerators, processes dispersant in rubber compounds fillers, softeners (plasticizers). Direct injection of stearic acid in the rubber helps to improve the distribution of the components and the degree of adaptability of the rubber compound.

Widespread use of stearic acid is found in pharmaceuticals and cosmetics, where it acts as a component responsible for the formation of structure and emulsifier for creams. Stearic acid is also indispensable in the chemical laboratory. For polishing pastes stearic acid — a component unchanged. Salts of stearic acid are used in bitumen for road construction, and the extraction of certain ores.
