The comprehensive physicochemical parameters of Dodecylamine Polyoxyethylene Ether AC-1210 (CAS: 26635-75-6) cover basic product properties, physical properties, chemical indicators, and usage characteristics. All data are sourced from the internal control standards of Guoli Chemical.

Basic Product Information

Dodecylamine Polyoxyethylene Ether AC-1210, chemical full name Polyoxyethylene (10) Dodecyl Ether, molecular formula C32H66O11, molecular weight approx. 626. This product is a nonionic surfactant, but due to its raw material being dodecyl primary amine, the molecular structure retains tertiary amine groups, thus possessing weak cationic characteristics. This unique structural design endows the product with excellent interfacial activity and wide compatibility. The product appearance is a colorless to slightly yellow liquid, and packaging specifications include 50 kg plastic drum, 200 kg plastic drum, and IBC tote.

Parameter Interpretation and Application Suggestions

HLB value of 13.5 indicates that the product has strong hydrophilicity and belongs to O\/W type emulsifiers, suitable for oil-in-water emulsion formulations such as pesticide emulsifiable concentrates, water emulsions, and water-based industrial cleaning agents. This HLB range also enables wetting and solubilization functions. Combined with the cloud point of 60~80°C, it can stably perform emulsification and detergency in high-temperature cleaning scenarios (e.g., high-temperature high-pressure spray cleaning).

Surface tension of approx. 32 mN\/m and CMC value of 6.3×10-5 mol\/L reflect that the product can effectively reduce the surface tension of aqueous solutions at very low concentrations, meaning low dosage and high cost-effectiveness in actual formulations. It is suitable for applications requiring efficient wetting and spreading (e.g., enhancing pesticide foliar spray efficiency). Additionally, penetration power ≤30 seconds further confirms its ability to quickly wet solid surfaces, particularly suitable for rapid leveling in textile dyeing and finishing and crevice penetration in metal cleaning.

Low foam characteristic is one of the significant advantages of this product, especially suitable for industrial cleaning and metalworking fluid formulations where high foam is undesirable. Meanwhile, strong alkali resistance and wide pH application range (pH 6.0~8.0 for 1% aqueous solution, but remains surface-active in acidic and alkaline media) allow safe use in various complex conditions such as acidic corrosion inhibition and alkaline cleaning.

Precautions
