Stearic Acid Product Details
Product Description
Stearic Acid is a saturated long-chain fatty acid commonly derived from natural animal or vegetable fats and oils. It appears as a white, waxy solid with a mild odor. This versatile compound is widely used in various industries, including cosmetics, pharmaceuticals, rubber, plastics, and detergents. Due to its excellent emulsifying, thickening, and stabilizing properties, Stearic Acid serves as a key ingredient in numerous formulations.
Production Process
Stearic Acid is typically produced through hydrolysis and hydrogenation of triglycerides found in palm oil, coconut oil, or tallow. The process involves:
- Hydrolysis: Fats and oils are subjected to high-temperature steam treatment, breaking them down into glycerol and free fatty acids.
- Fractional Distillation: The fatty acids are separated based on their boiling points, isolating Stearic Acid.
- Purification & Hydrogenation: The separated acid undergoes refining and hydrogenation to improve purity and stability.
- Crystallization & Drying: The purified Stearic Acid is crystallized into a solid waxy form and dried before packaging.
