Description

Polyethyleneglycol Alkyl (3-Sulfopropyl) Diether, Potassium Salt is a high-purity anionic surfactant belonging to the class of sulfobetaine-like ether sulfonates. This compound is valued for its excellent water solubility, stability across a wide pH range, and superior surface-active properties, making it a critical performance additive. It is primarily needed by formulators in the personal care, home care, and industrial cleaning sectors seeking mild yet effective surfactants with enhanced compatibility and foam characteristics.

Application

• Personal Care Formulations: Used as a primary or co-surfactant in shampoos, body washes, facial cleansers, and other rinse-off products for its mildness and rich lather.
• Home & Institutional Cleaning: An effective ingredient in liquid dish soaps, hard surface cleaners, and all-purpose cleaners due to its grease-cutting ability and compatibility with other ingredients.
• Industrial & Metalworking Fluids: Serves as a wetting agent, emulsifier, and corrosion inhibitor in coolant and cleaner formulations.
• Textile Processing: Functions as a leveling agent, dye dispersant, and antistatic agent in dyeing and finishing baths.
• Agricultural Adjuvants: Enhances the spreading and absorption of pesticides and herbicides on plant surfaces.
• Emulsion Polymerization: Acts as a stabilizer and emulsifier in the production of latexes and acrylic polymers.

Quality Control

Our Polyethyleneglycol Alkyl (3-Sulfopropyl) Diether, Potassium Salt is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency, purity, and performance. A comprehensive Certificate of Analysis (COA) documenting identity, assay, impurity profile, and key physical parameters is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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 quality.
