AEO9（CAS 9002-92-0）: The Green Surfactant Powering Sustainable Textile Processing

In the textile industry and numerous related industrial sectors, the selection of cleaning and processing aids is crucial, as it not only affects the final product quality but also influences the environmental friendliness and sustainability of the production process. Fatty alcohol polyoxyethylene ether AEO9 (CAS No. 9002-92-0), as an outstanding non-ionic surfactant, is playing an irreplaceable role across multiple industries with its multifaceted advantages, serving as a key driver for promoting green development in these sectors.

In the wool textile industry, degreasing is a critical step in wool processing, directly determining the cleanliness, softness, and subsequent dyeing effects of wool fibers. Traditional degreasing agents often contain strong alkalis or solvent-based components. While they offer some degreasing capability, they tend to damage wool fibers and lack environmental friendliness. The emergence of AEO9 has introduced a new option for wool degreasing.

AEO9 possesses excellent wetting and emulsifying properties, enabling it to rapidly penetrate wool fibers, effectively break down grease, wax, and various impurities, significantly improving degreasing efficiency while minimizing fiber damage. In hard water environments, traditional anionic surfactants are prone to forming calcium and magnesium soaps, which impair degreasing effectiveness. In contrast, AEO9 exhibits outstanding hard water resistance, maintaining stable performance under varying water quality conditions to ensure consistent degreasing quality. Moreover, AEO9 has a near-neutral pH, unlike strongly alkaline degreasing agents, and does not damage the natural scale structure of wool, preserving the fiber's softness and luster. Additionally, its favorable biodegradability surpasses that of alkylphenol ethoxylates (APEO), aligning with the green development trends of the modern textile industry. Today, AEO9 has become one of the mainstream components in wool degreasing agents. It is gradually replacing APEO, which some companies previously used but carries environmental hormone risks, offering comparable performance with greater environmental benefits as an ideal alternative.

Beyond degreasing, wool scouring is equally important. AEO9 plays a key role in wool scouring agents. It gently removes grease, sweat stains, and dirt from wool while effectively preventing fiber felting, allowing the wool to retain its natural elasticity and fluffiness. This lays a solid foundation for subsequent processing and final product quality.

In the pretreatment stages of cotton, synthetic fibers, and other fabrics, AEO9 is also an indispensable component. As a primary ingredient in scouring agents, it efficiently removes spinning oils, sizing agents, and impurities, making the fabric surface cleaner. This creates optimal conditions for subsequent dyeing processes, significantly improving dye uniformity and enhancing the overall quality of the fabric.

The low-foaming and easy-rinsing characteristics of AEO9 make it a preferred active ingredient for high-end liquid detergents. Whether in household detergents or industrial cleaning agents, AEO9 ensures effective cleaning while reducing the number of rinses, conserving water resources, and meeting market demands for efficient and environmentally friendly cleaning products.

In industrial fields such as synthetic fiber oiling agents and textile auxiliaries, AEO9 serves as a stable emulsifier, enhancing the compatibility of various components in formulations, optimizing processing performance, and ensuring smooth production processes and stable product quality.

As the demand for environmentally friendly and efficient auxiliaries grows across industries, fatty alcohol polyoxyethylene ether AEO9 (CAS No. 9002-92-0), with its exceptional performance, is widely applied in wool textiles, fabric processing, detergents, industrial emulsification, and many other areas. In the future, driven by green chemistry, the application prospects of AEO9 will become even broader, continuing to contribute to the development of these industries.
