Description

Sodium Isononyl Hydrogen Phosphate is an anionic surfactant and phosphate ester salt derived from isononyl alcohol. This compound is valued for its excellent emulsifying, wetting, and dispersing properties, particularly in challenging formulations. It serves as a critical performance additive in industrial cleaning, metal treatment, and textile processing, where stability and surface activity are paramount. Global manufacturers rely on its consistent quality for reliable process outcomes.

Application

• Industrial & Institutional (I&I) Cleaners: Key emulsifier and wetting agent in heavy-duty alkaline and acidic cleaning formulations for degreasing and scale removal.
• Metalworking Fluids: Acts as a lubricity agent and corrosion inhibitor in synthetic and semi-synthetic metalworking fluids and coolants.
• Textile Processing: Used as a scouring agent, dye leveling assistant, and antistatic agent in fiber and fabric treatment baths.
• Emulsion Polymerization: Functions as an anionic surfactant and stabilizer in the production of acrylic, vinyl acetate, and styrene-butadiene latexes.
• Pesticide & Agrochemical Formulations: Employed as a dispersant and wetting agent in emulsifiable concentrates (ECs) and suspension concentrates (SCs).
• Personal Care: Used in select rinse-off products as a mild surfactant and foam booster.

Quality Control

Our Sodium Isononyl Hydrogen Phosphate is manufactured under a stringent quality management system. Each batch is tested to ensure it meets precise specifications for active content, pH, and ionic character. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing key parameters to support your quality assurance protocols 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); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
