Description

2-Tetradecyloctadecanoic Acid is a high-molecular-weight, branched-chain fatty acid, also known by its CAS registry number 73756-39-5. This specialty chemical serves as a valuable intermediate and functional additive, prized for its hydrophobic and lubricating properties derived from its long, branched alkyl chain. It is essential for manufacturers in the polymer, lubricant, and specialty surfactant industries seeking to modify material surfaces, enhance flow properties, or create stable emulsions.

Application

• Polymer Additive: Acts as an internal or external lubricant and processing aid for plastics and synthetic resins to improve mold release and flow characteristics.
• Lubricant Formulation: Used as a base stock or additive in specialty greases, metalworking fluids, and synthetic lubricants requiring high thermal stability and water resistance.
• Surfactant Intermediate: Serves as a key raw material for synthesizing specialized anionic and nonionic surfactants with unique solubility and surface activity profiles.
• Corrosion Inhibitor: Functions as a hydrophobic film-forming agent in protective coatings and oilfield chemicals to prevent metal surface degradation.
• Cosmetic & Personal Care: Employed as an emollient and thickening agent in high-end cosmetic formulations, such as creams and lipsticks, for texture enhancement.
• Textile Auxiliary: Utilized as a softener and water-repellent finish for fibers and fabrics.
• Fuel & Oil Additive: Incorporated into fuel and lubricant packages to improve detergent/dispersant properties and reduce deposit formation.
