AEO-9, short for Alcohol Ethoxylate-9, is one of the most widely used nonionic surfactants in industry and daily chemical applications. It is suitable for many more applications than ionic surfactants. Aojin Chemical is a supplier of AEO-9, offering high-quality products at competitive prices.
I. The Core Function of AEO-9
The essential function of AEO-9 is to reduce the surface/interfacial tension of substances, thereby achieving functions such as emulsification, dispersion, wetting, and cleaning. The specific principles and performance are as follows:
II. Main Applications of AEO-9
Based on these functions, AEO-9 is used in a variety of industries, including daily chemicals, textiles, metalworking, and coatings. Specific applications are as follows:
1. Daily Chemicals (the core application area)
It is a core ingredient or auxiliary ingredient in mid-to-high-end laundry and cleaning products, primarily used to enhance detergency and mildness:
Detergents: laundry detergent, dishwashing liquid, dishwashing detergent, collar cleaner, and industrial heavy oil cleaners (such as machine tool cleaners);
Personal Care: mild facial cleansers, body washes, baby care products (such as baby laundry detergent and body wash), and conditioners (to assist in emulsifying silicone oil);
Household Cleaning: kitchen heavy oil cleaners, bathroom tile cleaners, and glass cleaners (to enhance wetting and detergency).
2. Textile Printing and Dyeing Industry
As a textile auxiliary, it solves wetting, dyeing, and cleaning issues in fabric processing:
Pretreatment: Serves as a "cleaner" and "wetting agent" during fabric desizing, scouring, and bleaching, helping to remove sizing, wax, and impurities from the fabric surface while also improving the penetration efficiency of chemical agents;
Dyeing: Serves as a "leveling agent," preventing dye from agglomerating and forming spots on the fabric surface, ensuring even color adhesion (especially suitable for polyester and cotton blended fabrics);
Finishing: Serves as an "emulsifier" in fabric softeners and antistatic agents, helping to emulsify and disperse oily softening ingredients (such as lanolin) for even adhesion to the fiber surface.
3. Metalworking Industry
Used for cleaning, rust prevention, and preparing cutting fluids for metal surfaces:
Metal Cleaners: Degreasers (removes cutting oil, stamping oil, and rust preventative oil from metal parts); Degreasing Agents (clean surfaces before electroplating);
Metalworking Fluids: Serves as an "emulsifier" in water-based cutting and grinding fluids, emulsifying and dispersing mineral oil (a lubricant) in water, simultaneously performing the triple functions of cooling, rust prevention, and lubrication.
4. Paint and Ink Industry
Serves as a "dispersant" and "emulsifier" to improve the stability and workability of coatings:
Water-based Paints: Serves as an "emulsifier" to emulsify resins (such as acrylic resins) and disperse pigments (such as titanium dioxide and colorants) in paints, preventing pigment settling and improving coating uniformity and adhesion.
Inks: Serves as an "emulsifier" in water-based inks, helping to disperse oil-based colorants in water, ensuring uniform color and preventing screen clogging during printing.
5. Other Industries
Leather Industry: Used as a "cleaner" during leather degreasing and tanning, removing surface grease and impurities to enhance leather softness.
Paper Industry: Used as a "wetting agent" during paper sizing, helping sizing agents (such as rosin) adhere evenly to the paper fiber surface, improving the paper's water resistance.
Emulsion Polymerization: Used as an "emulsifier" in the synthesis of polymer emulsions (such as styrene-butadiene rubber emulsions and acrylic emulsions), controlling the size and stability of latex particles.
