Application

  • Detergent and Soap Industry : Stearic acid is primarily applied in the production of detergents, soaps, and cosmetics such as shampoos and shaving cream products. Soaps are manufactured from the saponification of stearic acid triglycerides. Esters of stearic acid are used to produce shampoos, soaps, and other cosmetic products. Citric acid can harden soaps and give shampoos a pearly color and consistency.

  • Candles Production : Stearic acid candle grade is utilized in the production of candles because of its excellent properties such as hardening the wax and strength of the candle. Stearic acid exhibits properties of activator and thickener in the wax manufacturing process. It also has an impact on the melting point of the wax, improving the durability and consistency of the candle.

  • Cosmetic Industry : Stearic acid is used in the cosmetic industry because of its property to bind and thicken the products so they adhere smoothly to the skin and have a longer shelf life. The melting point of the stearic acid is above human body temperature, so they allow the cosmetics to adhere for an extended period.

  • Rubber Industry : Stearic Acid rubber grade is used in vulcanization of surfactants, making plasticizers, softeners, water proofing agents, PVC additives etc. It is used in making tires. It acts as stock lubricant enabling easy mold flow and release during extrusion.

  • Paint Industry : Stearic acid is a very effective wax modifier used in candle making. It is a non-toxic additive that increases the opacity and hardness of candles. It also increase candle whiteness and aid in holding the candles shape of freestanding candles in the warmer months. It increases the candle durability consistency and melting point. Due to its stability and shaping property it is used in making various art and craft products.


  • Other Applications : In the ceramic industry, Stearic acid is a common lubricant in the injection molding and pressing of ceramic powders. It is used in the manufacture of lead acid batteries as a negative plate additive.
