Applications

Personal Care and Cosmetics

• AEO (Natural C12–14 Fatty Alcohol Polyoxyethylene Ether) is used in personal care as a nonionic surfactant and emulsifier, with AEO-7 and AEO-9 commonly selected for mild cleansing systems where stable foam, good skin feel, and broad compatibility with other surfactants are needed. In shampoo systems, AEO-9 often acts as a secondary surfactant that supports foam stability and helps solubilize oil-soluble ingredients, which improves overall cleansing performance while keeping the formula comfortable on hair and scalp.
• In body wash and shower gel, AEO-9 is frequently positioned as a partial replacement for harsher sulfate surfactants, providing improved mildness while maintaining strong detergency on daily soils. This approach is especially useful in balanced surfactant blends where the product must deliver good foam quality, stable viscosity, and consistent rinse feel without sacrificing cleaning power.
• In skincare emulsions such as creams and lotions, AEO-9 is valued for building stable oil-in-water systems and supporting a smooth, spreadable texture. When used as an emulsifier in lotion-type formulas, AEO-9 helps bind the oil phase into fine droplets that resist separation and remain stable during storage, while also contributing to a refined sensory profile.
• In hand care, AEO-9 can be used at higher active levels to build effective liquid hand wash products that deliver cleansing with a milder profile and good foaming. These formulations often combine AEO with amphoteric surfactants and humectants to maintain moisture feel, while the nonionic structure improves compatibility across a wide pH window used by many rinse-off products.

Detergents and Household Cleaning

• AEO-7 and AEO-9 are widely applied in modern liquid laundry detergents because their nonionic character provides strong oily soil removal and good performance across a wide range of water conditions. Their low-foaming nature is particularly advantageous for high-efficiency washing machines, where excessive foam can reduce mechanical action and cause operational issues, and AEO-9 is commonly used as a secondary surfactant to boost grease cutting while keeping foam under control.
• In standard liquid laundry detergents, AEO-9 is typically used at moderate dosage to improve removal of sebum-type soils and reduce redeposition risk when paired with chelators and supporting surfactants. In ultra-concentrated systems, AEO-9 functions as part of a tightly balanced surfactant package that delivers high cleaning strength at lower water content, while still maintaining stability and workable viscosity after salt adjustment.
• For dishwashing liquids, AEO-7 and AEO-9 are used to improve grease removal while maintaining reasonable mildness to hands. The combination of two AEO grades is often chosen to balance wetting, emulsification, and detergency so the product performs well on mixed food soils without requiring overly aggressive surfactant loading.
• In all-purpose and hard-surface cleaners, AEO-9 serves as a primary surfactant due to its strong wetting and emulsifying ability on typical household and light industrial soils. Its versatility enables simplified formulas that combine AEO with solvents and acid/chelation systems to remove greasy residues and particulate soils from multi-surface substrates.
• In powder detergents, AEO-9 is used to enhance cleaning performance and dissolution behavior, supporting low-foaming machine-wash powders designed for modern washers. In builder-heavy systems, AEO-9 helps maintain detergency on oily soils and supports balanced cleaning across temperature ranges commonly used by consumers and institutional laundries.

Agriculture and Agrochemical Formulation

• AEO-9 is used as a key emulsifier in pesticide formulations, especially when the active ingredient has limited water solubility and must be delivered as a stable emulsion concentrate. In these systems, AEO-9 stabilizes oil-in-water emulsions so the concentrate can be diluted into spray tanks without phase separation, improving uniformity of application and helping keep dose delivery consistent in the field.
• AEO-based systems also function as wetting and spreading agents in herbicide and fungicide spray programs, where improved leaf coverage is critical for performance. By reducing surface tension, AEO helps spray droplets spread more evenly over waxy plant surfaces, increasing contact area and supporting better penetration and uptake of the active ingredient.
• In agricultural spray adjuvants, AEO-9 is used at low final-spray concentrations to enhance spreading and wetting without excessive foaming or instability. These adjuvants are often designed for flexible tank-mix compatibility, and the AEO grade selection allows the formulator to tune balance between wetting strength and emulsion stability across diverse actives and water qualities.
• AEO-9 is also used as an emulsifier/dispersant in seed treatment systems where uniform coating of the seed surface is important. In these applications, AEO supports even distribution of the active ingredient and assists the formation of a consistent film layer when used with film-formers, helping improve handling and application consistency.

Textile Processing and Auxiliaries

• In textile scouring and pretreatment, AEO-7 and AEO-9 act as wetting agents and emulsifiers that help remove waxes, oils, and processing soils from fibers and fabrics. Their performance supports improved wettability and cleaner fabric surfaces, which directly benefits subsequent dyeing and finishing steps by enabling more uniform chemical penetration.
• During dyeing and printing, AEO-9 can function as a leveling agent and process auxiliary that helps regulate dye migration and improve shade uniformity. This role is particularly useful in processes where controlled wetting and managed interaction between dye, fiber, and bath chemistry are necessary to reduce unevenness and processing variability.
• In textile finishing, AEO grades are used as emulsifiers for silicone softeners and related finishing agents, forming stable emulsions that deliver consistent hand feel and softness. The emulsification role is critical in achieving stable particle distribution and reliable fabric finishing performance during padding and exhaustion processes.
• AEO series products also appear in multi-purpose textile auxiliary packages that combine wetting, emulsifying, and dispersing functions. These systems are designed to support multiple processing stages such as desizing, scouring, and general cleaning, improving operational efficiency and overall fabric quality.

Industrial and Institutional Cleaning, Metal Processing

• AEO surfactants are commonly used in industrial degreasers and alkaline cleaning systems where strong emulsification of oils and greases is required. AEO-7 and AEO-9 contribute to rapid wetting and soil lift, enabling effective removal of machining oils and heavy soils from metal surfaces in both immersion and spray-cleaning operations.
• In metal processing, AEO-based blends are formulated with builders and chelators to provide robust degreasing while maintaining stability in high-alkalinity environments. Their nonionic structure supports good compatibility and helps reduce sensitivity to water hardness, which is important in industrial cleaning where water quality varies.
• AEO products are also used in institutional cleaners for hard surfaces where the formula must cut mixed soils while remaining easy to rinse. Their low-foam profile is useful in floor cleaning and automated equipment cleaning, where foam control supports faster operation and fewer rinse cycles.

Paper, Leather, and Other Process Industries

• In paper recycling and deinking, AEO-9 is used as a wetting and emulsifying agent that helps detach inks from fibers and keep ink particles dispersed for removal. This improves the efficiency of deinking operations and supports cleaner pulp streams for downstream paper production.
• In leather processing, AEO-7 and AEO-9 function as degreasing agents and emulsifiers that help remove natural fats and oils from hides. Their emulsification behavior supports stable carry-away of unwanted lipids while helping maintain processing control and consistency.
• Beyond direct processing roles, AEO products are used as general dispersants and wetting agents in various industrial steps where stable aqueous processing is required. This broad utility is driven by adjustable HLB across grades, allowing formulators to match AEO selection to oil-in-water emulsification needs or stronger wetting requirements.

Surfactant Intermediates and Downstream Synthesis

• AEO-3 is used as a key intermediate feedstock for producing Alcohol Ether Sulfate (AES), where it serves as the ethoxylated alcohol backbone that is subsequently sulfated and neutralized. This makes AEO-3 important not only as a finished nonionic surfactant, but also as a building block for anionic surfactants used in detergents and personal care.
• In broader surfactant manufacturing, AEO grades can be positioned as starting materials for amphoteric surfactants and specialized emulsifiers, depending on downstream chemistry requirements. This intermediary value supports integrated product portfolios where multiple surfactant families are derived from controlled ethoxylation grades.
