Description

Poly(Oxy-1,2-Ethanediyl), α-Phosphono-ω-(Octadecenyloxy)-, Dikaliumsalz, (Z)- (Eo 2-35 Mol) is a potassium salt of a phosphated oleyl alcohol ethoxylate, a specialized anionic-nonionic surfactant. This compound is engineered to deliver exceptional wetting, emulsification, and dispersing properties, particularly in challenging formulations. It is a critical performance additive for industries requiring stable emulsions and effective surface activity, such as agrochemicals, textiles, and industrial cleaning. The product is supplied under CAS No. 59929-26-9.

Application

• Agrochemical Formulations: Acts as a key emulsifier and wetting agent in pesticide and herbicide concentrates (ECs, SEs), enhancing spray coverage and system stability.
• Textile Processing: Used in scouring, dyeing, and finishing baths as a detergent and leveling agent for improved fiber wetting and uniform dye uptake.
• Industrial & Institutional (I&I) Cleaning: Serves as a high-performance surfactant in heavy-duty cleaners, degreasers, and metalworking fluids for superior oil emulsification.
• Paint & Coating Additives: Functions as a pigment dispersant and grinding aid, improving color development and preventing settling in aqueous systems.
• Leather Processing: Employed in fatliquoring and dyeing processes to ensure even penetration of oils and dyes into the leather matrix.
• Paper & Pulp Industry: Aids in de-inking processes and acts as a dispersant for coatings and fillers.

Quality Control

Our production of this surfactant adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as active matter content, pH, and cloud point are rigorously tested. Certificates of Analysis (COA) documenting these specifications are provided with every shipment 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 performance.
