Description

26-(4-Isooctylphenoxy)-3,6,9,12,15,18,21,24-Octaoxahexacosan-1-Ol is a high-purity, non-ionic surfactant and specialty chemical intermediate, valued for its unique amphiphilic structure combining a hydrophobic isooctylphenol group with a hydrophilic polyethylene glycol chain. This compound is essential for formulators requiring precise control over surface tension, emulsification, and solubility in complex systems. It is primarily sought by manufacturers in the polymer, agrochemical, and advanced material sectors for creating stable emulsions, dispersants, and functional additives.

Application

• Polymerization Emulsifier & Stabilizer: Acts as a critical surfactant in emulsion and suspension polymerization processes for acrylics, vinyl acetate, and styrene-butadiene rubber (SBR).
• Agrochemical Formulations: Used as a key component in pesticide and herbicide emulsifiable concentrates (EC) and suspension concentrates (SC) to enhance stability and spreading.
• Industrial Lubricant & Metalworking Fluid Additive: Serves as an emulsifier and corrosion inhibitor in synthetic coolants and drawing compounds.
• Textile & Leather Processing Aid: Functions as a leveling agent, dye dispersant, and softening aid in fiber treatment baths.
• Paint & Coating Additive: Employed as a wetting and dispersing agent to improve pigment incorporation and film formation in water-based coatings.
• Specialty Material Synthesis: Utilized as a macromonomer or building block for synthesizing advanced surfactants, dendrimers, and polymeric materials.

Quality Control

Our production of 26-(4-Isooctylphenoxy)-3,6,9,12,15,18,21,24-Octaoxahexacosan-1-Ol adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including assay, hydroxyl value, and ethylene oxide content determination, to ensure consistency and compliance with agreed specifications. Certificates of Analysis (COA) documenting purity, identity, and key physical-chemical parameters are provided with each shipment 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 a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture. For long-term storage, consider using an inert gas blanket to minimize potential oxidation.
