Description

Decanoic Acid,2-[[(4-Sulfophenoxy)Carbonyl]Oxy]Ethyl Ester,Sodium Salt is a specialized anionic surfactant and ester derivative of decanoic (capric) acid, designed for high-performance applications requiring both hydrophobic and hydrophilic properties. Its molecular structure, featuring a sulfonated aromatic moiety, provides excellent emulsifying, dispersing, and wetting capabilities in demanding formulations. This compound is essential for industrial chemists and formulators in sectors such as agrochemicals, coatings, and advanced material synthesis, where precise surface activity and ionic character are critical.

Application

• Agrochemical Formulations: Acts as a key surfactant and emulsifier in pesticides, herbicides, and fungicides to enhance droplet spread, adhesion, and systemic activity on plant surfaces.
• Industrial Coatings & Inks: Serves as a dispersing and wetting agent for pigments and fillers, improving color development, stability, and application properties in water-based systems.
• Polymerization & Material Science: Used as an emulsifier in emulsion polymerization processes (e.g., for styrene, acrylates) and as a functional additive to modify surface properties of polymers and composites.
• Textile & Leather Processing: Functions as a leveling agent, dye dispersant, and softening auxiliary to ensure uniform dye uptake and improved fabric handle.
• Detergent & Cleaning Systems: Incorporated into industrial and institutional cleaning products for its grease-cutting and soil-suspending properties in hard surface cleaners.
• Oilfield Chemicals: Utilized in drilling muds and enhanced oil recovery formulations as a rheology modifier and surfactant to improve fluid performance.
