Stearylamine Polyoxyethylene Ether AC-1830 (CAS No.: 26635-75-6) is a high-performance nonionic surfactant produced by the addition reaction of stearyl amine with ethylene oxide (average 30 EO units), with an average molecular weight of approximately 1590. The product appears as a light yellow to yellow paste or solid (melting point around 20-30°C); temperature-dependent morphological changes are normal physical phenomena and do not affect performance.
This product possesses dual characteristics of nonionic and weak cationic properties, imparting unique interfacial adsorption capabilities and broad matrix affinity. Its HLB value is as high as 16~17, with a cloud point exceeding 100°C. It is readily soluble in water and organic solvents, maintaining excellent chemical stability under acidic, alkaline, and high-hardness water conditions. Additionally, the product exhibits outstanding emulsifying dispersibility, superior wetting and spreading properties, and low-foaming characteristics, and it can be well compounded with anionic, cationic, and nonionic surfactants.
Stearylamine Polyoxyethylene Ether AC-1830 is manufactured by Haian Guoli Chemical Co., Ltd., with an active content of ≥99% and tertiary amine content of ≥95%. It is suitable for various application scenarios, including leveling agents in textile dyeing, emulsifiers in pesticides, corrosion inhibition and lubrication in metal processing, softening and antistatic treatment in daily chemicals, and industrial cleaning, making it a versatile industrial auxiliary agent.

Textile Dyeing and Finishing: When used as a leveling agent, its excellent retarding and migrating ability helps dyes evenly penetrate fibers, reducing color spots and shade differences; as an antistatic agent, it reduces static accumulation during synthetic fiber processing, improving spinnability and fabric hand feel. Recommended dosage varies according to process formulations, typically 0.5%~3%.
Agrochemical Formulations: As a high-efficiency nonionic emulsifier, it can stably disperse oily pesticide active ingredients in water to form uniform emulsions, significantly enhancing efficacy and storage stability. Recommended dosage is 2%~8% of the total formulation.
Metal Processing and Rust Prevention: Used as a corrosion inhibitor, it forms a protective film on metal surfaces to inhibit corrosion; as a lubricant component, it enhances lubrication during cutting, drawing, and other processing operations. Recommended dosage is 0.5%~5% of the working fluid.
Daily Chemical Products: Added to laundry detergents, fabric softeners, and other products to reduce static generation and impart a soft and smooth feel to garments. Recommended addition amount is 1%~5% of the total formulation.
Industrial Cleaning: Suitable for metal degreasing and hard surface cleaning formulations, offering high oil removal efficiency with low foaming and easy rinsing. Recommended dosage is 1%~10% of the total cleaning solution.
