Description

Octadecanoic Acid, Octacosyl Ester is a high-molecular-weight ester derived from stearic acid and octacosanol. This compound serves as a versatile, long-chain wax ester, valued for its excellent lubricating properties, stability, and hydrophobic nature. It is a critical raw material for formulators in the cosmetics, plastics, and specialty lubricants industries seeking to enhance product performance and texture.

Application

• As a thickening agent and texture enhancer in cosmetic and personal care formulations such as lipsticks, creams, and solid perfumes.
• Functioning as a lubricant and processing aid in the manufacture of plastics and polymers to improve mold release and surface finish.
• Used as a key component in synthetic wax blends for coatings, polishes, and candle making.
• Acting as a water-repellent agent in textile and leather treatment applications.
• Serving as a base material for specialty greases and high-temperature lubricants.
• Potential use as a phase change material (PCM) in thermal energy storage systems due to its high melting point.
