Description

2-Ethyl-2-[[(1-Oxooctadecyl)Oxy]Methyl]Propane-1,3-Diyl Distearate is a high-purity synthetic ester compound, valued for its excellent lubricity, thermal stability, and hydrophobic properties. This chemical serves as a versatile and effective intermediate and additive in advanced material formulations. It is primarily needed by manufacturers in the plastics, cosmetics, and specialty lubricants industries seeking to enhance product performance and processing characteristics.

Application

• Plastic Additive: Acts as an internal and external lubricant and processing aid in PVC, polyolefins, and engineering plastics to improve flow, reduce friction, and prevent sticking during molding and extrusion.
• Cosmetic & Personal Care Ingredient: Used as an emollient, viscosity modifier, and skin-conditioning agent in creams, lotions, and makeup formulations for a smooth, non-greasy feel.
• Specialty Lubricant & Grease Component: Functions as a synthetic base oil or thickener in high-performance lubricants, offering excellent oxidation stability and low-temperature properties.
• Coating & Ink Additive: Imparts slip, mar-resistance, and improved surface texture in paints, varnishes, and printing inks.
• Rubber Processing Aid: Enhances mold release and improves dispersion of fillers in rubber compounds during mixing and calendering.
• Textile Auxiliary: Serves as a softening agent and lubricant for synthetic fibers and yarns to reduce breakage and improve handle.
• Adhesive & Sealant Modifier: Used to adjust rheology, improve flexibility, and reduce tack in various adhesive systems.
• Research & Development: Employed as a key intermediate in the synthesis of more complex esters and polymeric materials for specialized applications.
