Dodecylamine Polyoxyethylene Ether AC-1202 is a nonionic surfactant produced by ethoxylation of primary fatty amines. It exhibits cationic properties in acidic media, possessing the dual functionality of both nonionic and cationic surfactants.
Detailed Description
Dodecylamine Polyoxyethylene Ether AC-1202 (CAS No.: 26635-75-6, also known as Polyoxyethylene (2) Dodecyl Ether, Laureth-2, AEO-2, etc.) is a special surfactant manufactured by Haian Guoli Chemical Co., Ltd. The product is synthesized via ethoxylation using primary fatty amines as starting materials. It appears as a colorless to slightly yellow transparent liquid with good fluidity, making it easy to handle and formulate.
The most prominent feature of this product is its "dual identity" — it behaves as a nonionic surfactant under normal conditions, but exhibits cationic characteristics in acidic media, offering high flexibility in complex formulation systems. It has strong emulsifying capabilities, providing excellent emulsion stability for various oil phases and solvent systems. Its wetting and spreading properties are good, effectively reducing interfacial tension. The dispersing performance is outstanding, offering long-lasting dispersion and suspension ability for both inorganic and organic particles. Additionally, the product has high chemical stability, resisting hydrolysis or deactivation in acidic, alkaline, and hard water environments. It is compatible with many additives and can be freely formulated with nonionic, cationic, and amphoteric surfactants.

Application Suggestions
Dodecylamine Polyoxyethylene Ether AC-1202 has a wide range of applications, covering six core areas:
- Pesticide Emulsifiers: Used in emulsifiable concentrates, microemulsions, and water-emulsion formulations, significantly improving emulsification dispersion and penetration, enhancing efficacy.
- Textile Printing and Dyeing Auxiliaries: Used as antistatic agents and softeners to eliminate fiber static, improve fabric hand feel, and enhance leveling in dyeing and finishing processes.
- Industrial Cleaning Agents: With excellent wetting, penetration, and degreasing ability, suitable for metal surface cleaning and heavy oil hard surface cleaning formulations.
- Metalworking Fluids: Provides emulsification, lubrication, and anti-rust functions in cutting fluids, grinding fluids, etc., extending tool life and improving workpiece surface finish.
- Leather Degreasing Agents: Rapidly penetrates and removes natural fats from raw hides evenly without damaging the grain, providing a clean base for subsequent tanning and dyeing.
- Paint Dispersants: Effectively adsorbs on pigment surfaces through steric hindrance, preventing particle flocculation and sedimentation, ensuring color storage stability and uniform film color.
Precautions
- Wear chemical safety goggles, impermeable gloves, and protective clothing during operation. Avoid direct contact with eyes and skin.
- Ensure good ventilation in the operation area, and consider local exhaust to prevent accumulation of vapors or mists.
- Store in a cool, dry, well-ventilated area. Keep containers tightly sealed, away from heat sources, sparks, open flames, and strong oxidizers.
- Use promptly after opening; seal unused product tightly and follow the "first-in, first-out" principle.
- In case of leakage, collect with inert absorbent material (e.g., sand, vermiculite). Prevent entry into drains or soil.
- Dispose of waste in accordance with local environmental regulations, preferably through high-temperature incineration by qualified facilities.
