Description

Octanoic Acid, Heneicosyl Ester is a high-purity, long-chain fatty acid ester derived from caprylic acid. This specialty chemical serves as a versatile intermediate and functional additive, valued for its hydrophobic properties and chemical stability. It is primarily utilized by manufacturers in the personal care, lubricant, and polymer industries seeking to modify surface characteristics and enhance product performance.

Application

• Personal Care & Cosmetics: Acts as an emollient, skin-conditioning agent, and viscosity modifier in creams, lotions, and lipsticks.
• Lubricant & Grease Formulation: Used as a synthetic base oil or additive to improve lubricity, thermal stability, and water repellency.
• Polymer & Plastic Additive: Functions as an internal or external lubricant and processing aid in plastics manufacturing.
• Surface Coatings: Imparts water resistance and modifies flow properties in paints, inks, and protective coatings.
• Textile Auxiliaries: Employed as a softening agent and water-repellent finish for fibers and fabrics.
• Chemical Synthesis: Serves as a key intermediate for producing more complex esters, surfactants, and specialty chemicals.
