Stearic Acid, chemically known as octadecanoic acid (CAS 57-11-4), is a cornerstone chemical compound with an extensive history and a critical role in modern manufacturing. Its inherent properties as a saturated fatty acid make it a foundational ingredient for a vast array of products, from everyday personal care items to advanced industrial applications. As a leading manufacturer and supplier of Stearic Acid in China, we are dedicated to providing businesses with the high-quality material they need to create innovative and effective products.

Chemical Profile and Properties of Stearic Acid

Stearic Acid is an 18-carbon saturated fatty acid with the chemical formula CH₃(CH₂)₁₆COOH. It typically appears as a white or slightly yellowish waxy solid. Its key properties include:

  • Melting Point: Approximately 69.3 °C (156.7 °F), making it solid at room temperature.
  • Solubility: It is sparingly soluble in water but soluble in organic solvents like ethanol and ether.
  • Reactivity: As a carboxylic acid, it can undergo esterification, saponification, and reduction, forming salts (stearates) and esters that have diverse industrial uses.
  • Occurrence: It is naturally abundant in many animal and vegetable fats and oils.

These characteristics make it a highly versatile chemical. Procurement specialists frequently search for terms like 'buy stearic acid 57-11-4' or 'high purity stearic acid supplier' to ensure they obtain a product suited for their specific needs.

The Broad Spectrum of Stearic Acid Applications

The utility of Stearic Acid spans numerous industries:

  • Cosmetics and Personal Care: A key emollient, emulsifier, and thickener in creams, lotions, soaps, and shampoos.
  • Food Industry: Used as a food additive (E570) for emulsification and stabilization.
  • Lubricants and Greases: Forms essential metallic stearates that act as thickeners and lubricants.
  • Plastics and Rubber: Acts as a lubricant and processing aid.
  • Candle Manufacturing: Improves hardness and opacity.
  • Pharmaceuticals: Used as an excipient in tablet formulations.

Understanding these applications is vital for businesses looking to source effectively. Whether you are in the market for 'stearic acid price' information or seeking a reliable 'supplier in China', a thorough understanding of the material's properties and applications is essential.
