Description

Didodecyldimethylammonium Diisooctyl Phosphate is a high-purity quaternary ammonium phosphate salt, functioning as a versatile cationic surfactant and phase transfer catalyst. Its unique structure provides excellent emulsifying, dispersing, and antistatic properties, making it a critical component in advanced formulations. This compound is essential for industries requiring high-performance surface modification and stabilization, such as specialty polymers, coatings, and advanced material synthesis.

Application

• Polymer & Resin Additive: Acts as an internal antistatic agent and processing aid for plastics and synthetic fibers.
• Coating & Ink Formulations: Serves as a dispersant and leveling agent to improve pigment wetting and film uniformity.
• Phase Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases in organic synthesis.
• Emulsion Stabilizer: Used in the preparation and stabilization of oil-in-water (O/W) and water-in-oil (W/O) emulsions.
• Textile Auxiliary: Imparts softness and antistatic properties to synthetic fabrics during finishing.
• Corrosion Inhibitor: Functions as a component in protective coatings and lubricant additives for metal surfaces.
