Description

26-(4-Nonylphenoxy)-3,6,9,12,15,18,21,24-Octaoxahexacosan-1-Yl Acetate is a specialized non-ionic surfactant and chemical intermediate featuring a unique structure combining a nonylphenol moiety with a long polyethylene glycol (PEG) chain terminated by an acetate group. This compound matters for its ability to act as a highly effective emulsifier, dispersant, and solubilizer in complex formulations, offering a balance of lipophilic and hydrophilic properties. It is primarily needed by manufacturers in the polymer, agrochemical, and specialty chemical industries for applications requiring tailored surface activity and compatibility.

Application

• As a key emulsifier and stabilizer in the production of advanced polymer dispersions and latexes.
• As a dispersing agent in agrochemical formulations such as herbicides and pesticides to enhance active ingredient solubility and field performance.
• As a surfactant intermediate for the synthesis of more complex specialty chemicals with specific HLB values.
• In the formulation of industrial cleaners and degreasers, where its surfactant properties aid in soil removal and wetting.
• As a coalescing aid or plasticizer in coating and adhesive systems to improve film formation and flexibility.
• In research and development as a model compound for studying the behavior of ethoxylated nonylphenol derivatives.

Quality Control

Our production of 26-(4-Nonylphenoxy)-3,6,9,12,15,18,21,24-Octaoxahexacosan-1-Yl Acetate adheres to strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistency, purity, and compliance with agreed specifications. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, and ethylene oxide distribution are available upon request to support your quality assurance processes.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect product quality and performance.
