AEO-3 is a non-ionic surfactant with an ethylene oxide (EO) addition number of 3 in the fatty alcohol polyoxyethylene ether series. It belongs to the low EO type product and has a chemical formula of, where R is mostly a fatty hydrocarbon group (commonly used as raw materials for lauryl alcohol and coconut oil). 1、 Core physical and chemical properties Appearance and solubility At room temperature, it is a light yellow transparent oily liquid with slightly improved hydrophilicity compared to AEO-1 and AEO-2, but still slightly weaker. It is slightly soluble in water and can form a turbid liquid after stirring; Easy to dissolve in organic solvents such as ethanol, ether, mineral oil, and oil systems. The hydrophilic lipophilic balance (HLB) value is about 7-8, belonging to the water in oil (W/O) emulsifier, and also possessing a certain auxiliary ability for water in oil (O/W) emulsification. performance parameters Hydroxyl value: approximately 160-170 mgKOH/g PH value (1% aqueous solution): 5.0~7.0 (neutral) Hazen color: ≤ 30 Moisture content: ≤ 1.0% Chemical stability and mildness Acid resistant, alkali resistant, and hard water resistant, with stable performance within the pH range of 3-11. It is not easily degraded by polyoxyethylene chains at high temperatures (<120 ℃). Low irritation to the skin and eyes, with a biodegradation rate of over 90%, meeting environmental standards. 2、 Main purpose AEO-3 is rarely used alone and is mostly used as an emulsifier, dispersant, co solvent, and other surfactant in combination. Its application scenarios are concentrated in the industrial and daily chemical fields Pesticide industry As the core emulsifier of emulsion (EC), when combined with anionic emulsifiers such as sodium dodecylbenzenesulfonate, it can evenly disperse pesticide raw materials in the oil phase, form a stable emulsion system, and improve the storage stability and spraying effect of pesticides. Textile and Leather Industry Used as a fiber oil component, added to the spinning oil of synthetic fibers such as polyester and nylon, it has lubricating and anti-static effects, reducing fiber breakage and entanglement. Emulsifying agents used as fatliquoring agents in leather processing help oil penetrate into the interior of leather fibers, enhancing the softness and glossiness of leather. In the field of daily chemical and cosmetics Used as an emulsifier in oil-based skincare products, makeup remover oils, and other products to improve the extensibility of the oil system and prevent product delamination; It can also be used as the cosolvent of essence and essential oil to improve the dispersity of oil soluble ingredients. Metal processing and coating industry Metal working fluid (cutting fluid, emulsified oil) is used as emulsion stabilizer to enhance the stability of lotion and avoid oil-water separation. As a wetting and dispersing agent in the production of coatings and inks, it promotes the uniform dispersion of pigments and fillers, and enhances the leveling and adhesion of coatings.

Sodium Laureth Sulfate 3EO (SLES-3EO) is an anionic surfactant.  3EO indicates that its molecule contains 3 ethoxy (-CH₂CH₂O-) units attached to the lauryl hydrophobic chain. It is a widely used mild surfactant in the daily chemical and cleaning industries. Basic Structure and Properties Chemical Structure: The general structural formula is: CH3(CH2)10CH2(OCH2CH2)3OSO3Na. It mainly consists of three parts: Hydrophobic group: Lauryl group (C₁₂ alkyl chain) Connecting group: 3 ethoxy units Hydrophilic group: Sodium sulfate ester group Core Performance Outstanding Mildness: Compared to SLS (0EO) and SLES-1EO, the introduction of 3 ethoxy units significantly reduces skin and eye irritation, making it a commonly used mild cleansing and foaming ingredient in personal care products. Excellent Water Solubility: The increased number of ethoxy units enhances hydrophilicity, maintaining good solubility even at low temperatures and preventing precipitation and stratification. Balanced Foaming and Cleaning: It produces rich and dense foam that is easy to rinse off, and has moderate cleaning power, effectively cleaning grease and dirt without excessive degreasing that leads to dry skin. Strong Hard Water Resistance: It exhibits good stability in hard water containing calcium and magnesium ions, and the cleaning effect does not significantly decrease. Good Compatibility: It can be compounded with non-ionic and amphoteric surfactants (such as cocamidopropyl betaine, alkyl glycosides), further improving mildness and foaming properties; caution is needed when compounding with cationic surfactants to avoid precipitation. Main Application Areas Personal Care Products It is a core ingredient in shampoos, shower gels, facial cleansers, and baby care products, especially suitable for sensitive skin and infant care formulations, with a typical addition ratio of 5%–20%. Household Cleaning Products Used in dishwashing detergents, laundry detergents, hand soaps, etc., balancing cleaning power and mildness, reducing irritation to the skin of the hands. Industrial Applications It can be used as a wetting agent in the textile industry, a pesticide emulsifier, and a leather degreasing agent, achieving efficient processing under mild conditions. Differences from similar products Product Eo Number Water-Soluble Mildness Detergency SLS 0 General Lower Strong SLES-1EO 1 Better Moderate Stronger SLES-2EO/3EO 2-3 Very Good Higher Moderate Precautions: Although generally mild, high concentrations (>20%) may still irritate sensitive skin; therefore, the amount used in formulations should be controlled. Store in a sealed container in a cool, dry place, avoiding contact with strong acids and high temperatures to prevent hydrolysis and loss of activity.
