What Is AEO-9?
AEO-9, also known as Primary Alcohol Ethoxylate 9EO, is a high-EO nonionic surfactant produced by the ethoxylation of primary fatty alcohols with approximately 9 moles of ethylene oxide (EO).
Compared with lower EO grades such as AEO-2 and AEO-3, AEO-9 exhibits significantly higher hydrophilicity, water solubility, detergency, and wetting performance. It is widely used in household detergents, industrial cleaners, textile auxiliaries, hard surface cleaning formulations, and various aqueous surfactant systems.
The EO number directly influences hydrophilic-lipophilic balance (HLB) and formulation behavior. Higher EO grades such as AEO-9 are especially suitable for aqueous cleaning systems requiring strong detergency, grease removal, emulsification stability, and formulation compatibility.
AEO-9 also demonstrates excellent compatibility with anionic, amphoteric, and nonionic surfactants, making it highly versatile for detergent blending and industrial cleaning formulations.
Key Functions
AEO-9 functions as a high-performance nonionic surfactant providing detergency, emulsification, wetting, dispersion, and formulation stability in household and industrial cleaning systems.
- Strong Detergency Performance
AEO-9 provides excellent removal of oils, grease, and particulate soils in aqueous cleaning systems. Its high EO structure enhances cleaning efficiency across various industrial and household applications. - Excellent Water Solubility
Due to its higher EO content, AEO-9 exhibits strong water solubility and stable performance in water-based formulations. - Emulsification Stability
AEO-9 effectively emulsifies oils and hydrophobic materials, helping maintain stable dispersion and formulation consistency. - Wetting and Penetration
AEO-9 improves wetting and penetration on hard surfaces, textiles, and industrial substrates, supporting faster and more effective cleaning action. - Surfactant Compatibility
AEO-9 demonstrates excellent compatibility with anionic and amphoteric surfactants, helping optimize detergency, foam balance, and formulation stability. - Formulation Versatility
AEO-9 is widely used in detergent blending systems due to its balanced cleaning, emulsification, and formulation-supporting performance.
Applications
AEO-9 is widely used in household detergents, industrial cleaning formulations, textile auxiliaries, and surfactant systems requiring strong detergency and water solubility.
- Laundry Detergents
AEO-9 is commonly used in liquid laundry detergents to improve detergency, grease removal, and surfactant compatibility. - Dishwashing Liquids
Used in dishwashing formulations to improve oil emulsification, foam stability, and cleaning performance against grease residues. - Industrial Cleaning
AEO-9 functions as a high-performance emulsifier and wetting agent in industrial degreasers, hard surface cleaners, and processing cleaners. - Textile Processing
Applied in textile auxiliaries and wetting formulations to improve penetration, emulsification, and processing consistency. - Metal Cleaning Systems
Used in metal cleaning formulations to improve oil removal, detergency, and formulation stability. - Surfactant Blending
AEO-9 is commonly used in blended detergent systems to optimize cleaning efficiency, wetting, and emulsification performance.

FAQs
What is the difference between AEO-9 and AEO-3?
AEO-9 contains significantly higher EO content, resulting in much greater water solubility, detergency, and wetting performance. AEO-3 is more oil-soluble and better suited for oil-phase emulsification systems.
What is the difference between AEO-9 and AEO-7?
AEO-9 provides stronger hydrophilicity, detergency, and aqueous cleaning performance, while AEO-7 offers a more balanced profile between emulsification, wetting, and foam control.
What is the difference between low-EO and high-EO Alcohol Ethoxylates?
Low-EO grades are more lipophilic and oil-soluble, making them suitable for W/O emulsions and oil-phase systems. High-EO grades such as AEO-9 are more hydrophilic and better suited for aqueous detergents and industrial cleaners.
Can AEO-9 be blended with anionic surfactants?
Yes. AEO-9 demonstrates excellent compatibility with anionic surfactants such as SLES and LABSA, helping improve detergency balance, emulsification, and formulation stability.
Why is AEO-9 widely used in industrial cleaning?
AEO-9 provides strong emulsification, detergency, wetting, and grease removal performance, making it highly effective in industrial degreasers and hard surface cleaning formulations.
