Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-(2-Sulfoethyl)-.Omega.-(2-Sulfoethoxy)-, Disodium Salt is a high-purity, anionic surfactant and dispersant belonging to the class of sulfonated polyethylene glycol derivatives. This compound is valued for its exceptional water solubility, thermal stability, and powerful surface-active properties, making it a critical performance additive in demanding formulations. It is primarily needed by manufacturers in the textile, construction, and personal care industries seeking to enhance wetting, dispersion, and process stability.

Application

• Textile Processing: Acts as a superior dispersant and leveling agent in dyeing processes, ensuring uniform color uptake and reducing dye agglomeration.
• Construction Chemicals: Used as a highly effective plasticizer and water-reducing agent in cement and concrete admixtures to improve workability and final strength.
• Personal Care & Cosmetics: Serves as a mild surfactant and emulsifier in shampoos, body washes, and skin care products, providing stable lather and formulation consistency.
• Industrial Cleaning: Functions as a key component in alkaline and acidic cleaning formulations for its superior wetting and soil suspension capabilities.
• Paper & Pulp Industry: Employed as a dispersant for pigments and fillers to improve sheet formation and coating quality.
• Agricultural Formulations: Enhances the dispersion and stability of active ingredients in pesticide and herbicide suspensions and emulsions.
• Oilfield Chemicals: Used in drilling muds and completion fluids as a rheology modifier and dispersant for solids control.
• Polymerization: Acts as an emulsifier and stabilizer in emulsion polymerization processes for synthetic rubbers and plastics.

Quality Control

Our Poly(Oxy-1,2-Ethanediyl), .Alpha.-(2-Sulfoethyl)-.Omega.-(2-Sulfoethoxy)-, Disodium Salt is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity, performance, and compliance with relevant industry specifications. Certificates of Analysis (COA) documenting key parameters such as assay, sulfonate content, pH, and moisture 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). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy. Keep away from strong oxidizing agents.
