Description

2-Ethylhexene-1-Sulfonic Acid Sodium Salt is a versatile anionic surfactant and intermediate with significant industrial utility. Its value lies in its excellent surface-active properties, solubility in water, and utility as a precursor for synthesizing other valuable sulfonate derivatives. This compound is essential for manufacturers and formulators in sectors requiring high-performance emulsifiers, wetting agents, or specialized chemical building blocks.

Application

• Surfactant & Emulsifier: Used in the formulation of industrial and institutional cleaning products, detergents, and emulsion polymerization processes.
• Textile Processing: Acts as a wetting agent, leveling agent, and dye dispersant in textile manufacturing and finishing.
• Enhanced Oil Recovery (EOR): Employed as a chemical additive to alter interfacial tension and improve oil displacement in petroleum production.
• Chemical Synthesis: Serves as a key intermediate for the production of other specialty sulfonates, surfactants, and functional monomers.
• Personal Care & Cosmetics: Can be utilized as a mild surfactant or foaming agent in select cosmetic and personal care formulations.
• Agricultural Formulations: Used as an adjuvant in pesticide and herbicide formulations to improve spreading and adherence.
• Leather Processing: Functions as a wetting and penetrating agent in leather tanning and finishing operations.
• Paper & Pulp Industry: Applied as a dispersant and processing aid in paper manufacturing.

Quality Control

Our 2-Ethylhexene-1-Sulfonic Acid Sodium Salt is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, composition, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, and impurity profiles are available upon request to support your quality assurance protocols.

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 product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
