Sodium Laureth Sulfate 1EO refers to sodium lauryl ether sulfate, a common anionic surfactant, where 1EO indicates that the lauryl hydrophobic chain in its molecule is connected to one ethoxy (-CH₂CH₂O-) unit. Basic Structure and Properties Chemical Structure: Its general structural formula is:CH3(CH2)10CH2(OCH2CH2)1OSO3Na.   It consists of three parts: Hydrophobic group: Lauryl group (C12 alkyl chain) Connecting group: 1 ethoxy unit Hydrophilic group: Sodium sulfate ester group Core Performance Excellent surface activity: It can significantly reduce the surface tension of water, and has strong emulsifying, detergency, and foaming abilities, producing rich and stable foam. Improved water solubility: Compared to sodium lauryl sulfate (SLS) without ethoxy groups, the introduction of one ethoxy unit improves its water solubility, making it less likely to precipitate at low temperatures. Optimized mildness: It is slightly less irritating than SLS, but still belongs to the category of moderately irritating surfactants, suitable for cleaning products. Hard water resistance: It has stronger hard water resistance than SLS, maintaining good cleaning performance in water containing calcium and magnesium ions. Compatibility: It can be compounded with nonionic, cationic (caution is needed to avoid precipitation), and other anionic surfactants. Main Application Areas Personal care products: Used in shampoos, shower gels, facial cleansers, hand soaps, etc., playing a core role in cleaning and foaming. Due to the low number of EO units, it has strong detergency and is often compounded with mild surfactants (such as cocamidopropyl betaine) to reduce irritation. Household cleaning products: Used in laundry detergents, dishwashing detergents, hard surface cleaners, etc., utilizing its emulsifying and foaming abilities to improve cleaning efficiency. Industrial field: It can be used as an emulsifier in pesticide and paint formulations, and also as a wetting agent in the textile industry and a degreasing agent in the leather industry. 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: At high concentrations, it can be irritating to the skin and eyes. The proportion added to formulations needs to be controlled (usually 5%-15% in personal care products). Avoid high temperatures and strong acidic environments during storage, otherwise hydrolysis may occur, reducing its activity.

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.
