Stearic Acid (Triple Pressed) 25kg

Stearic acid is a saturated fatty acid with the chemical formula C18H36O2. It is a solid, waxy substance that is odorless and tasteless. Stearic acid is commonly found in natural fats and oils, such as animal fats (beef, pork, and chicken) and vegetable oils (such as coconut oil, palm oil, and shea butter).

Stearic acid is widely used in various industries and applications. In the food industry, it serves as a food additive and is commonly used as a thickener, emulsifier, and stabilizer. It can be found in a variety of food products, including baked goods, confectionery, margarine, and chocolate.

Outside of the food industry, stearic acid has many applications. It is used in the production of candles, cosmetics, soaps, detergents, and lubricants. It is also utilized as a coating for pills and tablets in the pharmaceutical industry.

From a chemical perspective, stearic acid belongs to the class of fatty acids, which are long-chain carboxylic acids. It is called a saturated fatty acid because its carbon chain is fully saturated with hydrogen atoms, meaning it does not contain any carbon-carbon double bonds. This saturation gives stearic acid its solid form at room temperature and makes it less prone to rancidity compared to unsaturated fats.

Overall, stearic acid is a versatile compound with various industrial applications, primarily as a thickener, emulsifier, stabilizer, and lubricant.



Stearic acid has several major and common uses across various industries. Some of the key applications of stearic acid include:

  1. Personal Care and Cosmetics: Stearic acid is widely used in the production of personal care products such as lotions, creams, soaps, and cosmetics. It functions as an emulsifier, thickener, and stabilizer, providing texture, consistency, and stability to the products.
  2. Candle Making: Stearic acid is commonly used in the production of candles. It serves as a hardening agent, allowing candles to have a longer burning time, improved structure, and reduced dripping.
  3. Pharmaceutical Industry: Stearic acid is utilized in the pharmaceutical industry as an excipient, a substance added to medications to provide certain characteristics or aid in their manufacturing process. It is commonly used as a lubricant and a binder for pills and tablets.
  4. Food Industry: Stearic acid is used as a food additive in various food products. It functions as a thickener, emulsifier, and stabilizer. It can be found in items such as baked goods, confectionery, margarine, and chocolate.
  5. Industrial Lubricants: Stearic acid is utilized in the production of industrial lubricants, including those used in automotive and machinery applications. It provides lubrication, reduces friction, and helps to prevent corrosion.
  6. Rubber Industry: Stearic acid is added to rubber compounds during the manufacturing process. It acts as a dispersing agent, aiding in the uniform distribution of fillers and reinforcing materials in rubber products.
  7. Plastics Industry: Stearic acid is used as a lubricant and release agent in the production of plastics. It helps to improve the flow properties of molten plastic and facilitates the release of plastic components from molds.

These are some of the major and common uses of stearic acid. Its versatility as a thickener, emulsifier, stabilizer, lubricant, and excipient makes it a valuable ingredient in a wide range of industries.

Safety Guidelines

When using stearic acid, it is important to take certain precautions to ensure safe handling and usage. Here are some precautions to consider:
  1. Personal Protective Equipment (PPE): Wear appropriate PPE, including gloves, goggles or face shield, and protective clothing, when handling stearic acid. This helps protect the skin, eyes, and clothing from direct contact and potential irritation.
  2. Ventilation: Ensure proper ventilation in the area where stearic acid is being used. This helps to minimize exposure to any fumes or vapors that may be released during handling.
  3. Avoid Inhalation: Avoid breathing in stearic acid dust or fumes. If working with powdered or aerosolized forms of stearic acid, use a dust mask or respirator to prevent inhalation.
  4. Storage: Store stearic acid in a cool, dry, and well-ventilated area away from direct sunlight, heat sources, and incompatible materials. Follow any specific storage instructions provided by the manufacturer.
  5. Fire Hazards: Stearic acid is flammable and can pose a fire hazard. Keep it away from open flames, sparks, and ignition sources. Use appropriate fire safety measures and have fire extinguishing equipment readily available.
  6. Handling and Spills: When handling stearic acid, take care to prevent spills. In case of a spill, contain and clean it up promptly using appropriate absorbent materials. Avoid contact with skin and eyes during cleanup.
  7. Compatibility: Be aware of the compatibility of stearic acid with other substances. Avoid mixing or storing it with incompatible materials, such as strong oxidizing agents, alkalis, or reactive metals, as it may lead to hazardous reactions.
  8. Follow Manufacturer’s Instructions: Always follow the manufacturer’s instructions, guidelines, and safety data sheets (SDS) provided with the specific stearic acid product you are using. These documents provide important information on safe handling, storage, and disposal.
It’s important to note that the above precautions are general guidelines, and specific safety measures may vary depending on the concentration, form, and application of stearic acid. Therefore, it is advisable to consult the product’s SDS and seek guidance from the manufacturer or relevant safety professionals for comprehensive safety information.
