Octadecyl polyoxyethylene ether AC-1830 belongs to the alkylamine polyoxyethylene ether class of surfactants, with the chemical name polyoxyethylene (30) octadecylamine (PEG-30 octadecylamine). The product appears as a light yellow to yellow paste or solid, and its morphology changes with temperature, which is a normal physical phenomenon and does not affect performance. This product is primarily nonionic but also exhibits weak cationic characteristics. This unique "dual ionic property" gives it excellent interfacial adsorption capacity and broad substrate affinity, allowing good compatibility and compounding with anionic, cationic, and nonionic surfactants.
As one of the core products of Guoli Chemical, AC-1830 has excellent emulsifying and dispersing performance, enabling efficient emulsification and stable dispersion of various oils and hydrophobic substances. It also possesses outstanding chemical stability, maintaining stable performance under acidic, alkaline, and hard water conditions, making it suitable for a wide range of applications. Additionally, the product has good wetting and spreading properties, effectively reducing interfacial tension and enhancing the spreading and penetration ability of liquids on solid surfaces.
Leveling agent: AC-1830 has excellent retarding and migrating abilities, helping dyes to evenly dye fibers, effectively reducing color spots and color differences, and improving dyeing quality. Antistatic agent: Reduces static electricity generated by friction during spinning and weaving processes of synthetic fibers (such as polyester, acrylic, etc.), preventing fiber entanglement and dust adsorption, and improving spinnability and fabric hand feel.
As a highly effective nonionic emulsifier, AC-1830 allows oil-based pesticide active ingredients (such as emulsifiable concentrates, aqueous emulsions, etc.) to stably disperse in water, forming a uniform emulsion, enhancing the dispersion and adhesion of pesticide active ingredients, improving efficacy utilization rate and formulation storage stability.
Corrosion inhibitor: Forms a protective film on metal surfaces, inhibiting corrosion caused by acidic media, moisture, and atmospheric environments, extending workpiece service life. Lubricant component: Provides lubrication protection in metal cutting, drawing, and other processing processes, reducing friction coefficient and processing temperature, and improving processing accuracy and surface finish.
Added to laundry detergents, fabric softeners, and other products, it imparts a soft feel to textiles by adsorbing on fiber surfaces while providing antistatic effects, reducing static discomfort during clothing wear, and improving rewetting and wearing comfort.
As a nonionic surfactant component used in industrial formulations such as metal degreasers and hard surface cleaners, it offers excellent wetting, penetration, and emulsifying power, highly effective in removing heavy oil stains, with low foam and easy rinsing, suitable for industrial cleaning scenarios.

When using AC-1830 in formulations, it is recommended to adjust the dosage according to the specific application scenario. In textile leveling, it is usually added as a component of the leveling agent; in pesticide emulsification formulations, it is used as a primary or auxiliary emulsifier; in metalworking fluids, it can be compounded as a corrosion inhibitor and lubricating aid; in daily chemical softeners, it exerts both antistatic and softening effects. Due to its good compounding compatibility, it can be used synergistically with various ionic surfactants to achieve optimal results.
