Description

2-(Sodiosulfo)Hexanoic Acid 2-Ethylhexyl Ester is a specialized anionic surfactant and intermediate, valued for its unique combination of hydrophobic and hydrophilic properties derived from its sulfonated ester structure. This compound is essential for formulators seeking to enhance the solubility, stability, and surface activity of complex chemical systems. It is primarily needed by manufacturers in the polymer, coatings, and specialty chemical industries for applications requiring tailored emulsification and dispersion.

Application

• Polymerization Aid: Acts as an emulsifier and stabilizer in emulsion polymerization processes for synthetic rubbers and plastics.
• Coatings & Inks: Functions as a wetting and dispersing agent to improve pigment compatibility and film formation in water-based formulations.
• Textile Processing: Used as a leveling agent and softener in dyeing and finishing operations to ensure uniform color uptake.
• Detergent Intermediates: Serves as a key building block for the synthesis of high-performance, biodegradable anionic surfactants.
• Lubricant Additives: Imparts anti-wear and extreme pressure properties when incorporated into specialty lubricant formulations.
• Adhesive Formulations: Enhances adhesion and workability in pressure-sensitive and structural adhesive systems.

Quality Control

Our production of 2-(Sodiosulfo)Hexanoic Acid 2-Ethylhexyl Ester adheres to stringent quality management protocols. Every batch is analyzed to ensure it meets precise chemical and physical specifications, with a focus on consistent active content and low levels of residual solvents or by-products. Certificates of Analysis (COA) documenting purity, assay, and other critical parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product performance.
