Acide stearique t/p

Stearic acid is a saturated fatty acid found in various natural sources, such as shea butter, coconut oil and palm oil. It is widely used in the cosmetics and pharmaceutical industries for its emollient and stabilizing properties.


Stearic acid t/p

Stearic acid is a saturated fatty acid with the chemical formula C18H36O2. It is a waxy, white, and solid compound that is found in various animal and vegetable fats. Stearic acid is commonly used in a wide range of industrial and consumer applications due to its versatile properties. Here are some key characteristics and uses of stearic acid:


Saturated Fatty Acid: Stearic acid is a saturated fatty acid, which means it does not contain any double bonds in its carbon chain. This gives it stability and a high melting point.

  • Waxy Solid: It is typically found as a white, odorless, and tasteless waxy solid at room temperature.
  • Insolubility: Stearic acid is largely insoluble in water but soluble in organic solvents, such as ether and chloroform.
  • Hydrophobic: It is hydrophobic, meaning it repels water and is often used to create water-resistant barriers.


  • Cosmetics and Personal Care: Stearic acid is used in the production of cosmetics and personal care products such as creams, lotions, and soaps. It acts as an emulsifying agent and thickener.
  • Candles: It is used in candle manufacturing to harden and solidify wax, allowing candles to burn longer and with less dripping.
  • Pharmaceuticals: In the pharmaceutical industry, stearic acid is used as an excipient in the production of tablets and capsules.
  • Plastics and Polymers: Stearic acid is used as a lubricant and release agent in the production of plastic products.
  • Rubber Industry: It is used as a vulcanization activator in the rubber industry.
  • Food Industry: In the food industry, it is used as an emulsifier and a release agent for molded candies.
  • Lubricants: Stearic acid is used in the production of lubricants and greases.
  • Textiles: It is used as a softening agent and a lubricant in the textile industry.
  • Metalworking: In metalworking, stearic acid is used as a lubricant and anti-welding agent.
  • Pharmaceuticals: It is used as a lubricant in the production of pharmaceutical tablets and capsules.

The "t/p" specification you mentioned is unclear, but stearic acid is often available in different forms and specifications depending on its intended use.
