Description

Octadecadienyl Dihydrogen Phosphate is a specialized organophosphorus compound widely used as a high-performance surfactant and emulsifier. Its unique molecular structure, featuring a long unsaturated hydrocarbon chain linked to a phosphate group, provides excellent surface activity and compatibility with various formulations. This chemical is essential for manufacturers in the personal care, agrochemical, and polymer industries seeking to stabilize emulsions, improve wetting, and modify surface properties. We supply this material to meet the stringent quality and consistency demands of global industrial applications.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and stabilizer in creams, lotions, and sunscreens, providing a smooth texture and enhanced skin feel.
• Agrochemical Formulations: Used as a key component in pesticide and herbicide emulsions to improve spray coverage, adhesion, and active ingredient delivery.
• Polymer & Resin Production: Serves as an internal or external lubricant and release agent in plastic processing and composite materials.
• Textile & Leather Processing: Functions as a softening agent, antistatic agent, and dyeing auxiliary to improve fiber handling and finish quality.
• Industrial Cleaners & Detergents: Employed as a wetting and dispersing agent in heavy-duty cleaning formulations for industrial and institutional use.
• Lubricant Additives: Incorporated into metalworking fluids and synthetic lubricants to provide anti-wear and extreme pressure properties.

Quality Control

Our Octadecadienyl Dihydrogen Phosphate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, impurity profiling, and physical property verification, to ensure it meets precise customer specifications and industry standards. A Certificate of Analysis (COA) documenting purity, identity, and key parameters is provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and performance. Keep away from strong bases and incompatible materials.
