Description

Pentaerythritol Dioleate is a synthetic ester derived from pentaerythritol and oleic acid, functioning as a versatile non-ionic surfactant and lubricant. Its molecular structure provides excellent emulsifying properties, thermal stability, and compatibility with a wide range of organic materials. This compound is essential for formulators and manufacturers in industries requiring high-performance additives for lubrication, plasticization, and surface modification.

Application

• Polymer & Plastic Additive: Acts as an internal and external lubricant and plasticizer in PVC, polyolefins, and engineering plastics to improve processing and surface finish.
• Metalworking Fluids: Serves as a key component in synthetic and semi-synthetic cutting oils and drawing compounds, providing lubrication and corrosion protection.
• Cosmetic & Personal Care: Used as an emollient and thickening agent in creams, lotions, and hair care products for its smooth texture and skin compatibility.
• Textile Processing: Functions as a softening agent and lubricant for fibers and yarns, reducing friction during spinning and weaving operations.
• Paints & Coatings: Employed as a flow and leveling agent, as well as a pigment dispersant, in various solvent-based and oil-based formulations.
• Rubber Industry: Used as a processing aid and mold release agent to facilitate mixing, extrusion, and demolding of rubber compounds.

Quality Control

Our Pentaerythritol Dioleate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and compliance with agreed specifications. Key parameters such as ester content, acid value, hydroxyl value, and iodine value are monitored. A Certificate of Analysis (COA) detailing the results is provided with every shipment to guarantee product integrity and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is easily oxidized; for long-term storage, it is recommended to keep containers under an inert atmosphere (e.g., nitrogen) to maintain optimal quality. Keep away from strong oxidizing agents.
