Dodecyl Amine Polyoxyethylene Ether AC-1202 (CAS No.: 26635-75-6) is a nonionic surfactant produced by ethoxylation reaction using fatty primary amine as the starting material. It appears as a colorless to slightly yellow transparent liquid. Its unique molecular structure allows it to exhibit cationic properties in acidic media, combining the dual functions of both nonionic and cationic surfactants. This characteristic makes it flexible and widely applicable in many industrial fields.
The core performance advantages of this product are reflected in five aspects: strong emulsifying ability, providing excellent emulsion stability for various oil phases and solvent systems; good wetting and spreading performance, effectively reducing interfacial tension and increasing the spreading rate of liquids on solid surfaces; outstanding dispersing performance, providing long-lasting dispersion and suspension ability for inorganic and organic particles; high chemical stability, maintaining stable surface activity in acid, alkali, and hard water environments; and compatibility with various additives, allowing compounding with nonionic, cationic, and amphoteric surfactants.
From an industry distribution perspective, the application of AC-1202 covers multiple key fields from agricultural chemicals to industrial processing. In pesticide formulations, it acts as an efficient emulsifier to enhance efficacy; in textile printing and dyeing, it serves as an antistatic agent and softener to improve fabric quality; in industrial cleaning and metalworking, it performs wetting, degreasing, and lubrication functions; and it also demonstrates excellent process aid value in leather processing and coating dispersion.
| Industry Field | Application Process/Scenario | Function/Role |
|---|---|---|
| Pesticides | Emulsifiable Concentrate (EC), Microemulsion (ME), Emulsion in Water (EW) formulations | As a highly efficient nonionic emulsifier, it improves the emulsification and dispersion performance of formulations, enhances penetration, and boosts efficacy |
| Textile Printing and Dyeing | Antistatic finishing, softening finishing, dyeing and finishing processing | Eliminate static electricity on fibers, improve fabric hand feel, and enhance leveling |
| Industrial Cleaning | Metal surface cleaning, heavy grease hard surface cleaning, equipment cleaning, degreasing formulations | Wetting, penetrating, and degreasing, with auxiliary decontamination and corrosion inhibition functions |
| Metalworking | Cutting fluids, grinding fluids and other metalworking fluid formulations | Emulsification, lubrication and rust prevention, extending tool life and improving workpiece finish |
| Leather | Raw hide degreasing process | Rapid penetration to remove natural fats, uniform degreasing without damaging the leather surface, providing a clean base for tanning and dyeing |
| Coatings | Pigment and filler dispersion, paint preparation | Adsorb on the pigment surface, prevent particle flocculation and sedimentation through steric hindrance effect, ensuring storage stability and uniform coating color |
Compounding Recommendations: AC-1202 can be freely compounded with nonionic, cationic, and amphoteric surfactants. In acidic formulation systems, it can leverage the additional advantage of cationic characteristics, suitable for complex formulations that require both emulsification and antistatic functions. In pesticide emulsifiable concentrate formulations, it is recommended to be used in combination with nonionic emulsifiers to obtain a wider HLB value coverage range.
Dosage Reference: The specific dosage should be determined through experiments based on the target formulation system. In cleaning agents, the recommended addition amount is usually 2%–10% of the total formulation; in pesticide emulsifiable concentrates, as an emulsifier component, it typically accounts for 5%–15% of the total formulation; in metalworking fluids, 0.5%–5% is recommended. The above are general industry reference ranges; actual dosage should be based on formulation test results.
