Description

Ammonium Nonoxynol-4 Sulfate is an anionic surfactant derived from the ethoxylation and sulfation of nonylphenol. This compound is valued for its excellent wetting, dispersing, and emulsifying properties in aqueous systems. It is a critical ingredient for formulators in the personal care, textile, and industrial cleaning sectors who require effective and stable surface-active agents. Its ammonium salt form offers good solubility and compatibility in a variety of formulations.

Application

• Personal Care & Cosmetics: Acts as a primary surfactant and foaming agent in shampoos, body washes, and facial cleansers.
• Textile Processing: Used as a wetting agent, dispersant, and emulsifier in dyeing and finishing baths.
• Industrial & Institutional (I&I) Cleaners: Serves as a key component in liquid soaps, hard surface cleaners, and degreasers for its detergency.
• Agricultural Formulations: Employed as an adjuvant in pesticide and herbicide sprays to enhance wetting and spreading on plant surfaces.
• Emulsion Polymerization: Functions as a surfactant in the production of latexes and acrylic polymers.
• Metal Working Fluids: Used in formulations for its emulsifying and cleaning properties.

Quality Control

Our Ammonium Nonoxynol-4 Sulfate is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise specifications for active matter content, pH, and ionic composition. Certificates of Analysis (COA) documenting these 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, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep container tightly sealed when not in use to prevent absorption of atmospheric moisture.
