Stearic acid as a substance that is very useful and beneficial in making candles, plastics, food supplements, oil pastes and cosmetics, as well as for softening rubber. It is worth mentioning that this substance is also used to harden soaps, especially soaps made with vegetable oil.

Types of stearic acid:

  • Cosmetic grade stearic acid
  • Rubber grade stearic acid


Application of stearic acid:

  • -Industrial use for soap production (sodium or potassium salt of stearic acid are part of soaps)
  • -To produce acetates including sodium acetate, magnesium acetate, calcium lead acetate, lead acetate, aluminum lead acetate, iron acetate and potassium stearate.
  • -as oil-soluble paint solvents
  • -Lubricating agent for colored pencils
