Description

Stearic Acid 2-[(E)-1-Octadecenyloxy]Ethyl Ester is a high-purity, synthetic ester derivative of stearic acid, valued for its excellent lubricity, stability, and hydrophobic properties. This specialized chemical intermediate is crucial for formulators seeking to enhance the performance and texture of high-end personal care and industrial products. It is primarily utilized by manufacturers in the cosmetics, pharmaceuticals, and specialty lubricants industries to create stable emulsions, improve spreadability, and provide a non-greasy, protective barrier.

Application

• Cosmetic & Personal Care Formulations: Acts as a premium emollient, texture enhancer, and stabilizer in creams, lotions, lipsticks, and sunscreens.
• Pharmaceutical Topicals: Used as an excipient in ointments and creams to modify drug release and improve skin feel.
• Specialty Lubricants & Release Agents: Functions as a friction-reducing additive and mold release agent in plastics and rubber processing.
• Surface Coatings & Polishes: Imparts water repellency and a smooth finish to automotive and furniture polishes.
• Textile & Fiber Treatment: Serves as a softening and waterproofing agent for fabrics and technical textiles.
• Plastic Additive: Used as an internal and external lubricant to improve processing and surface quality of polymer compounds.
