Description

Diisooctylphenol is a versatile alkylphenol derivative, primarily valued as a key chemical intermediate and a non-ionic surfactant precursor. Its molecular structure provides excellent hydrophobic properties and chemical stability, making it a critical component in the synthesis of high-performance additives. This product is essential for manufacturers in the polymer, lubricant, and specialty chemical industries seeking to enhance product performance and process efficiency.

Application

• Surfactant & Detergent Intermediate: A primary raw material for the production of nonylphenol ethoxylate (NPE) alternatives and other non-ionic surfactants used in industrial and institutional cleaners.
• Polymer Additive: Acts as a stabilizer and antioxidant in the production of plastics, rubber, and elastomers, helping to prevent degradation during processing and extend product lifespan.
• Lubricant & Fuel Additive: Used in the formulation of engine oils, industrial lubricants, and fuel additives to improve viscosity index, oxidation resistance, and dispersancy.
• Chemical Synthesis: Serves as a crucial intermediate in organic synthesis for agrochemicals, pharmaceuticals, and other specialty chemicals.
• Resin Modifier: Employed in epoxy, phenolic, and alkyd resin systems to modify flexibility, adhesion, and curing characteristics.
• Adhesive & Sealant Formulation: Enhances the performance of adhesives, sealants, and coatings by improving wetting, flow, and compatibility.

Quality Control

Our Diisooctylphenol is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and isomer distribution, to ensure it meets precise specifications for industrial applications. Certificates of Analysis (COA) documenting identity, assay, and key physical properties are provided with each shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, open flames, and strong oxidizing agents. The container should be kept tightly sealed when not in use to minimize moisture absorption and prevent contamination.
