Description

Sodium 2-[2-[2-(Octylphenoxy)Ethoxy]Ethoxy]Ethanesulphonate is a high-performance anionic-nonionic surfactant, valued for its excellent wetting, emulsifying, and dispersing properties in demanding formulations. Its unique molecular structure, featuring a hydrophobic octylphenol chain linked to a hydrophilic ethoxysulphonate group, provides superior stability and compatibility across a wide pH range. This compound is essential for manufacturers in the agrochemical, textile, and industrial cleaning sectors seeking to enhance product efficacy and process efficiency.

Application

• Agrochemical Formulations: Acts as a key wetting agent, dispersant, and emulsifier in pesticides, herbicides, and fungicides to improve foliar spreading and active ingredient delivery.
• Textile Processing: Used in scouring, dyeing, and finishing operations as a detergent and leveling agent to ensure uniform color and fabric treatment.
• Industrial & Institutional (I&I) Cleaners: Serves as a primary surfactant in heavy-duty degreasers, metal cleaners, and hard surface cleaners due to its robust grease-cutting power.
• Paint & Coating Additives: Functions as a pigment dispersant and grinding aid to stabilize suspensions and prevent settling in water-based systems.
• Enhanced Oil Recovery (EOR): Employed in surfactant-polymer flooding formulations to reduce interfacial tension and mobilize residual oil.
• Personal Care & Cosmetics: Utilized in specialized rinse-off products where high foaming and emulsification are required, subject to appropriate grade and certification.
