AEO-9 is a representative nonionic surfactant of the EO type in the fatty alcohol polyoxyethylene ether series. It is formed by addition polymerization of fatty alcohols (mainly lauryl alcohol and cocoyl alcohol) with 9 ethylene oxide (EO) molecules, with a chemical formula of. Its hydrophilic lipophilic balance value (HLB) has strong adaptability and excellent cleaning, emulsifying, and wetting abilities, making it one of the most widely used AEO models in the daily chemical and industrial fields. 1、 Core physical and chemical properties Appearance and solubility At room temperature, it is a milky white paste like or light yellow viscous liquid, and gradually becomes a transparent liquid when the temperature is above 40 ℃; Easy to dissolve in water, forms a clear and transparent solution after dissolution, and is also soluble in polar organic solvents such as ethanol and ethylene glycol. The hydrophilic lipophilic balance (HLB) value is about 12-13, belonging to the oil in water (O/W) type emulsifier, with high emulsification efficiency and the ability to stably disperse various oil phase substances. Key performance parameters Hydroxyl value: about 90-100 mgKOH/g PH value (1% aqueous solution): 5.0~7.0 (neutral) Cloud point (1% aqueous solution): about 50-60 ℃ (after exceeding the cloud point, the aqueous solution becomes turbid and the surface activity slightly decreases, which can be restored after cooling) Moisture content: ≤ 1.0% Surface tension (0.1% aqueous solution, 25 ℃): approximately 32-35 mN/m Chemical stability and mildness Acid resistant, alkali resistant, and hard water resistant, with stable performance in the pH range of 3-11, and will not precipitate with calcium and magnesium ions in hard water. Its applicability is far superior to anionic surfactants. Low skin and eye irritation, with a biodegradation rate of over 90%, in compliance with EU REACH and domestic safety standards for daily chemical and food industries. High temperature stability is good, and the performance is stable when the temperature is below 120 ℃. Long term exposure to an environment above 120 ℃ can lead to slow degradation of polyoxyethylene chains. 2、 Main purpose AEO-9 can be used alone or in combination with anionic (such as LAS) and cationic surfactants to produce synergistic effects, with application scenarios covering multiple industries Daily chemical washing field As the core decontamination component of laundry detergent, washing powder and detergent, it has strong decontamination power, rich foam and is easy to rinse, mild and harmless, especially suitable for preparing high-end washing products. Used for personal cleaning products such as shower gel and hand sanitizer, it has both cleaning and moisturizing effects, reducing product irritation to the skin. Textile printing and dyeing industry In the pre-treatment of printing and dyeing (desizing, boiling, bleaching), it is used as an efficient wetting agent and detergent to help auxiliaries quickly penetrate fibers and remove impurities such as oil and pulp on fabrics. As a leveling agent in the dyeing process, it prevents dye aggregation, avoids fabric discoloration and color difference, and improves dyeing uniformity and brightness. In the process of synthetic fiber spinning, it can be used as an oil component, which has both lubricating and anti-static effects, reducing fiber breakage and entanglement.   3、 Comparison with EO models in the same series Type EO Bonus Number Hlb Value Cloud point (1% aqueous solution) Core Functional Differences AEO-7 7 10~12 40~50℃ Low foaming, wetting, emulsifying, suitable for medium and low temperature cleaning AEO-9 9 12~13 50~60℃ High cleaning power, high emulsification, and wider application AEO-10 10 13~14 60~70℃ High water solubility, strong stain removal, suitable for high-temperature cleaning

AEO-10 is a non-ionic surfactant of medium to high EO type in the fatty alcohol polyoxyethylene ether series. It is formed by addition polymerization of fatty alcohols (mainly lauryl alcohol and cocoyl alcohol) with 10 ethylene oxide (EO) molecules. Its chemical formula is. Its hydrophilicity is superior to AEO-7 and AEO-9, and it has the characteristics of strong stain removal, high emulsification, and high temperature resistance. It is a commonly used high-efficiency surfactant in the fields of daily chemical and industrial cleaning. 1、 Core physical and chemical properties Appearance and solubility At room temperature, it is a milky white paste like or light yellow viscous liquid, and when the temperature is above 45 ℃, it becomes a transparent liquid; Highly soluble in water, it forms a clear and uniform solution upon dissolution. It is also soluble in polar organic solvents such as ethanol and propylene glycol, but difficult to dissolve in non-polar solvents such as petroleum ether. The hydrophilic lipophilic balance (HLB) value is about 13-14, belonging to the oil in water (O/W) type emulsifier, with strong emulsifying ability and the ability to stably disperse high proportion oil phase systems. Key performance parameters Hydroxyl value: about 80-90 mgKOH/g PH value (1% aqueous solution): 5.0~7.0 (neutral) Cloud point (1% aqueous solution): about 60-70 ℃ (cloud point higher than AEO-7 and AEO-9, suitable for medium and high temperature cleaning scenarios, surface activity decreases after exceeding the cloud point, and can be restored by cooling) Moisture content: ≤ 1.0% Surface tension (0.1% aqueous solution, 25 ℃): about 30-33 mN/m Chemical stability and mildness Acid resistant, alkali resistant, and hard water resistant, with stable performance in the pH range of 3-12. It is not easily combined with calcium and magnesium ions to form precipitates and has stronger adaptability than most anionic surfactants. Low irritation to the skin and eyes, with a biodegradation rate of over 90%, meeting the safety standards for cleaning daily chemical and food processing equipment. High temperature stability is good, and the performance is stable when the temperature is below 120 ℃. Long term exposure to an environment above 120 ℃ can lead to the degradation of polyoxyethylene chains and reduce surface activity. 2、 Main purpose AEO-10 can be used alone or in combination with anionic (such as LAS, AES) and cationic surfactants to enhance efficiency. Its application scenarios cover multiple industries Daily chemical washing field As the core and efficient cleaning ingredient of laundry detergent, laundry powder, and dishwashing detergent, its cleaning power is superior to AEO-9, especially suitable for cleaning heavy oil contaminated clothes and tableware; Foam is rich and easy to rinse. It is gentle and does not hurt hands. It is often used in high-end washing products. It is used for personal care products such as shampoo and shower gel. It has both cleaning and emulsifying functions, can help dissolve oil soluble essence and plant extracts, and improve product stability. 3、 Comparison with EO models in the same series Type EO Bonus Number Hlb Value Cloud point (1% aqueous solution) Core Functional Differences AEO-7 7 10~12 40~50℃ Low foaming, wetting, emulsifying, suitable for medium and low temperature cleaning AEO-9 9 12~13 50~60℃ High cleaning power, high emulsification, and wider application AEO-10 10 13~14 60~70℃ High water solubility, strong stain removal, suitable for high-temperature cleaning
