Dodecylamine Polyoxyethylene Ether AC-1210 is widely used in five major industries: textile printing and dyeing, metal processing, daily chemical care, pesticide formulations, and industrial cleaning. As a multifunctional nonionic surfactant, it plays core roles such as leveling, emulsifying, corrosion inhibiting, conditioning, and penetration enhancing.
Detailed Description
Dodecylamine Polyoxyethylene Ether AC-1210 (CAS No.: 26635-75-6) is a nonionic surfactant with weak cationic characteristics, prepared by the addition reaction of ethylene oxide with dodecyl primary amine as the starting material. Its molecular structure contains both a polyoxyethylene ether hydrophilic segment and a long-chain alkyl hydrophobic group, while retaining the weak cationic feature of the tertiary amine group. This unique molecular design endows the product with excellent interfacial activity and wide compatibility.
The product maintains good surface activity in both acidic and alkaline media, with outstanding hard water resistance. It can be compounded with nonionic, anionic, cationic, and amphoteric surfactants, offering extremely high formulation flexibility. Its weak cationic property also confers affinity for negatively charged surfaces, allowing the formation of adsorption films on various substrates, providing additional functions such as antistatic and softening conditioning.
According to the application data of Guoli Chemical, AC-1210 has formed mature application solutions in multiple downstream industries. The following details its specific process uses in five core industries.
Industry Applications and Process Details
1. Textile Printing and Dyeing Industry
In textile printing and dyeing processes, AC-1210 is mainly used as:
- Acid dye leveling agent: Effectively regulates the dye uptake rate, avoiding color spots and unevenness, while enhancing dyeing depth and brightness.
- Low-temperature wool dyeing auxiliary: Reduces dyeing temperature, saving energy and protecting wool fiber structure and hand feel.
- Synthetic fiber antistatic finishing agent: Reduces static accumulation on synthetic fibers such as polyester and nylon during spinning and weaving, minimizing production faults and improving fabric wearing comfort.
2. Metalworking Industry
In metalworking and anti-rust processes, applications of AC-1210 include:
- High-efficiency corrosion inhibitor for acidic media: Significantly inhibits the corrosion rate of metal substrates during processes such as pickling and rust removal.
- Multifunctional additive for metal cutting fluids/anti-rust fluids: Combines emulsifying, corrosion-inhibiting, and lubricating functions, extending the service life of tools and processing fluids.
- Core component of metal cleaners: Emulsifies and disperses processing oils and greases on metal surfaces during cleaning, and provides inter-process anti-rust protection.
3. Daily Chemical Care Products Industry
In personal care, AC-1210 performs the following functions:
- Cationic conditioning agent: Improves wet combability and softness in shampoos and conditioners, enhancing hair gloss.
- Thickener: Optimizes product rheology and formulation stability, improving user experience.
- Mildness additive: Reduces irritation to skin and mucous membranes, suitable for mild products such as body washes.
4. Pesticide Formulation Industry
In agrochemicals, AC-1210 is an important auxiliary component:
- Pesticide emulsifier: Ensures uniform dispersion and formulation stability of active ingredients in emulsifiable concentrates, aqueous emulsions, and microemulsions.
- Synergistic wetting and penetrating agent for herbicides such as glyphosate: Enhances spreading, adhesion, and penetration of the spray solution on plant leaf surfaces, improving bioavailability and field control efficacy of active ingredients.
5. Industrial Cleaning Industry
In industrial and institutional cleaning, core applications of AC-1210 include:
- Core emulsifying and dispersing component for high-temperature and high-pressure cleaners: Effectively removes heavy oil stains, carbon deposits, and other stubborn dirt.
- Corrosion-inhibiting component in acidic cleaning formulations: Protects cleaning equipment and metal surfaces under acidic cleaning conditions.
- Efficient cleaning in hard water environments: Maintains excellent detergency in scenarios such as vehicle washing, mechanical degreasing, and cleaning of food processing equipment.

Application Recommendations
When selecting the application process for AC-1210, it is recommended to adjust the dosage based on the specific system pH and compounding requirements. In acidic systems (such as acid dye dyeing, acidic cleaning, and pickling corrosion inhibition), the stability and corrosion inhibition advantages of AC-1210 are particularly prominent. In pesticide formulations, it is recommended to use it as part of a composite emulsifying synergist rather than as a single emulsifier. In daily chemical formulations, attention should be paid to the synergistic compounding ratio with nonionic and amphoteric surfactants to achieve optimal conditioning and thickening effects.
Precautions
- This product is irritating to skin and eyes (H315/H319); wear chemical-resistant gloves and protective goggles during operation.
