Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-Hydro-.Omega.-Hydroxy-, Mono-C11-15-sec-Alkyl Ethers, Phosphates is a specialized class of anionic surfactants derived from ethoxylated and phosphated secondary alcohols. This compound is valued for its excellent emulsifying, wetting, and dispersing properties, particularly in challenging chemical environments. It is a critical ingredient for formulators in the industrial cleaning, metalworking, textile processing, and agrochemical sectors who require robust performance in acidic or solvent-based systems. The product, identified by CAS No. 68921-60-8, offers a versatile solution for creating stable formulations.

Application

• Industrial & Institutional (I&I) Cleaners: Acts as a key surfactant in acidic cleaners, degreasers, and solvent-based formulations for heavy-duty applications.
• Metalworking Fluids: Serves as an effective emulsifier and lubricity agent in synthetic and semi-synthetic cutting, grinding, and drawing fluids.
• Textile Processing: Used as a wetting agent, emulsifier, and antistatic agent in dye baths, scouring, and finishing operations.
• Agrochemical Formulations: Functions as an emulsifier and dispersant in pesticide and herbicide concentrates, especially for oil-in-water (O/W) emulsions.
• Paint & Coating Additives: Employed as a pigment dispersant and grinding aid to improve color development and stability in solvent-borne systems.
• Oilfield Chemicals: Utilized in drilling muds and production chemicals as an emulsifier and corrosion inhibitor adjuvant.
• Personal Care (Rinse-off products): Can be used as a secondary surfactant in acidic or clarifying hair care products for its cleansing and foam-boosting properties.

Quality Control

Our production of Poly(Oxy-1,2-Ethanediyl), .Alpha.-Hydro-.Omega.-Hydroxy-, Mono-C11-15-sec-Alkyl Ethers, Phosphates adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistency in key parameters such as active matter content, free acidity, and ethoxylation distribution. Certificates of Analysis (COA) documenting these results are available upon request. We support compliance with relevant global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). This material is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent absorption of atmospheric moisture. Keep away from strong acids and incompatible materials.
