Description

Poly(Ethylene Oxide) Nonylphenol Ether Phosphate Ester Sodium Salt is a high-performance anionic surfactant and emulsifier derived from the ethoxylation and phosphorylation of nonylphenol. This compound matters for its exceptional wetting, dispersing, and emulsifying properties, particularly in challenging aqueous systems. It is primarily needed by formulators in the industrial cleaning, textile processing, agrochemical, and metalworking fluid industries seeking stable and effective surface-active agents.

Application

• Industrial & Institutional (I&I) Cleaners: Acts as a key wetting agent and emulsifier in heavy-duty alkaline and acidic cleaners, degreasers, and floor care formulations.
• Textile Processing: Used as a scouring, leveling, and dyeing assistant due to its excellent compatibility with electrolytes and stability across a wide pH range.
• Agrochemical Formulations: Serves as an effective emulsifier and dispersant in pesticide and herbicide concentrates (ECs, SEs) to enhance spray performance and active ingredient stability.
• Metalworking Fluids: Functions as an emulsifier and corrosion inhibitor in synthetic and semi-synthetic coolants and drawing compounds.
• Paints & Coatings: Employed as a pigment dispersant and grinding aid to improve color development and stability in water-based systems.
• Paper & Pulp Industry: Utilized in de-inking processes and as a dispersant to control pitch and improve pulp drainage.
• Personal Care (Industrial Grade): Found in select industrial-grade cosmetic and toiletry formulations requiring specific emulsification properties.

Quality Control

Our Poly(Ethylene Oxide) Nonylphenol Ether Phosphate Ester Sodium Salt is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including assay (active matter), pH, moisture content, and ionic character. Certificates of Analysis (COA) documenting these parameters 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); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture which may affect product performance.
