Description

Poly(Oxy-1,2-Ethanediyl),.Alpha.-Hydro-.Omega.-Hydroxy-,Mono-C4-18-Alkyl Ethers,Phosphates,Potassium Salts CAS NO 70247-99-3 is a versatile anionic surfactant belonging to the phosphate ester class, specifically the potassium salts of alkoxylated alcohol phosphate esters. This compound is valued for its excellent emulsifying, wetting, and dispersing properties, combined with good electrolyte tolerance and stability across a range of pH conditions. It is a critical performance additive in demanding industrial and consumer formulations where robust surface activity and compatibility are required.

Application

• Industrial & Institutional (I&I) Cleaners: Acts as a primary surfactant and emulsifier in heavy-duty alkaline cleaners, degreasers, and floor care products.
• Textile Processing: Used as a wetting agent, lubricant, and antistatic agent in fiber spinning, dyeing, and finishing operations.
• Metalworking Fluids: Functions as an emulsifier and corrosion inhibitor in soluble oils and semi-synthetic metalworking fluids.
• Agricultural Formulations: Serves as an effective emulsifier and dispersant in pesticide and herbicide concentrates (EC, SC, EW formulations).
• Personal Care & Cosmetics: Employed as a mild surfactant and emulsifying agent in shampoos, bath products, and skin cleansers.
• Paints & Coatings: Acts as a pigment dispersant and grinding aid, improving color development and stability in water-based systems.
• Paper & Pulp Industry: Used as a debonding agent, dispersant, and processing aid.
• Oilfield Chemicals: Functions as an emulsifier and wetting agent in drilling muds and other production chemicals.

Quality Control

Our production of Potassium Alkyl Ether Phosphate adheres to a stringent quality management system. Each batch is analyzed against comprehensive specifications to ensure consistent performance, including active matter content, pH, and ionic character. Certificates of Analysis (COA) documenting these parameters are provided with every shipment. We support our global partners by ensuring our products and processes align with relevant industry standards and regulatory frameworks, including REACH compliance.

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); containers must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product characteristics.
