Description

Tridecyl Stearate is a high-purity, synthetic ester derived from stearic acid and tridecyl alcohol, valued for its excellent lubricity, thermal stability, and hydrophobic properties. This versatile chemical intermediate is crucial for formulators seeking to enhance product performance, reduce friction, and improve water resistance. It is primarily needed by manufacturers in the personal care, lubricant, plastic, and textile industries for its multifunctional role as an emollient, lubricant, and processing aid.

Application

• Personal Care & Cosmetics: Acts as a premium emollient and skin-conditioning agent in creams, lotions, and sunscreens, providing a non-greasy, smooth feel.
• Industrial Lubricants & Metalworking Fluids: Serves as a synthetic base oil or additive, offering excellent boundary lubrication, high flash point, and oxidation stability.
• Plastic & Polymer Processing: Functions as an internal and external lubricant and mold release agent in PVC, polyolefins, and engineering plastics to improve flow and surface finish.
• Textile & Fiber Manufacturing: Used as a spin finish component and softening agent for synthetic fibers to reduce friction and static during high-speed processing.
• Adhesives & Sealants: Imparts flexibility and water repellency while acting as a plasticizer in various adhesive formulations.
• Paints & Coatings: Employed as a flow and leveling agent to improve film formation and enhance surface gloss and smoothness.
