Description

Sodium Oleth-7 Phosphate is a versatile anionic-nonionic surfactant derived from oleyl alcohol ethoxylate. This compound is valued for its excellent emulsifying, wetting, and dispersing properties, particularly in challenging aqueous systems. It is a critical ingredient for formulators in the personal care, industrial cleaning, and textile processing industries seeking stable, high-performance products.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and solubilizer in creams, lotions, and hair care products, providing stable oil-in-water emulsions.
• Industrial & Institutional (I&I) Cleaners: Used in heavy-duty degreasers, alkaline cleaners, and metalworking fluids for its superior wetting and emulsification of oils and fats.
• Textile Processing: Serves as a wetting agent, lubricant, and antistatic agent in fiber and fabric processing, dyeing, and finishing baths.
• Agricultural Formulations: Employed as an emulsifier and dispersant in pesticide and herbicide concentrates to enhance stability and sprayability.
• Paints & Coatings: Functions as a pigment wetting and grinding aid, improving color development and dispersion stability in aqueous coatings.
• Oilfield Chemicals: Utilized in drilling muds and completion fluids as an emulsifier and corrosion inhibitor.

Quality Control

Our Sodium Oleth-7 Phosphate is manufactured under a cGMP-compliant quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including assay, pH, and active matter content. A comprehensive Certificate of Analysis (COA) documenting purity and key specifications is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 may affect product performance.
