Description

15-Methyl-3,6,9,12-Tetraoxahexadecyl Dihydrogen Phosphate is a specialized organophosphate surfactant and functional monomer with a unique polyether-phosphate structure. This compound matters for its ability to act as an effective emulsifier, dispersant, and surface-active agent, offering excellent compatibility with aqueous systems and other polar media. Industries requiring advanced surface modification, such as polymer synthesis, agrochemical formulation, and personal care, will find this phosphate ester particularly valuable for enhancing product performance and stability.

Application

• Polymer & Resin Modification: Used as a functional monomer or additive to impart hydrophilicity, improve adhesion, or modify surface properties in acrylics, polyurethanes, and epoxy systems.
• Agrochemical Formulations: Serves as a key emulsifier and dispersant in the production of pesticides, herbicides, and fungicides, enhancing the stability and efficacy of active ingredients.
• Personal Care & Cosmetics: Functions as a mild surfactant and emulsifying agent in skincare products, hair conditioners, and makeup, providing stabilization for oil-in-water emulsions.
• Textile & Leather Processing: Employed as a wetting agent, lubricant, and antistatic agent in fiber treatment, dyeing, and finishing processes to improve processing efficiency and product quality.
• Metalworking Fluids: Acts as a corrosion inhibitor and lubricity additive in synthetic and semi-synthetic metalworking coolants and drawing compounds.
• Industrial & Institutional Cleaners: Utilized in formulations for hard surface cleaners, degreasers, and detergent blends due to its surfactant and sequestering properties.

Quality Control

Our production of 15-Methyl-3,6,9,12-Tetraoxahexadecyl Dihydrogen Phosphate adheres to stringent quality management protocols to ensure batch-to-batch consistency and purity. Each lot is analyzed using advanced techniques including HPLC, NMR, and titration to verify critical parameters such as assay, phosphate content, and residual solvents. A comprehensive Certificate of Analysis (COA) documenting all test results is provided with every shipment to support your quality assurance and regulatory compliance needs.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to minimize exposure to atmospheric moisture, which can affect product quality and performance.
