Description

3,6,9,12-Tetraoxaoctadecyl Dihydrogen Phosphate is a specialized organophosphate surfactant and emulsifier, valued for its unique hydrophilic-lipophilic balance derived from its tetraethylene glycol spacer and phosphate head group. This compound is critical for formulating stable, high-performance emulsions and surface-active systems where precise control over interfacial properties is required. It is primarily sought by manufacturers in the agrochemical, personal care, and specialty polymer industries for its efficacy as a dispersant, wetting agent, and stabilizer.

Application

• Agrochemical Formulations: Acts as a key emulsifier and dispersant in pesticide and herbicide concentrates, enhancing spray coverage and active ingredient stability.
• Personal Care Products: Used in creams, lotions, and hair care formulations as a mild surfactant and emulsion stabilizer.
• Polymerization Aid: Serves as an emulsifier and stabilizer in emulsion polymerization processes for acrylics, vinyl acetate, and other polymers.
• Textile & Leather Processing: Functions as a wetting agent, lubricant, and antistatic agent in fiber treatment and finishing baths.
• Metalworking Fluids: Employed as a corrosion inhibitor and emulsifier in synthetic and semi-synthetic metalworking coolants.
• Industrial Cleaners: Enhances the degreasing and wetting power of alkaline and acidic cleaning formulations.

Quality Control

Our 3,6,9,12-Tetraoxaoctadecyl Dihydrogen Phosphate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, composition, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, acid value, and moisture content are provided and available upon request, supporting 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 room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality.
