Dodecylpolyoxyethylene Ether AC-1210 is a special surfactant combining nonionic and weakly cationic properties, with excellent emulsifying power, chemical stability, and wide compatibility as its core advantages.

Detailed Description

Dodecylpolyoxyethylene Ether AC-1210 (CAS No.: 26635-75-6) is prepared from dodecyl primary amine as the starting material through ethylene oxide addition reaction. Its molecular structure contains both polyoxyethylene ether hydrophilic segments and long-chain alkyl hydrophobic groups, while retaining the weakly cationic characteristics of tertiary amine groups. This unique molecular design makes it outstanding in interfacial activity, capable of rapidly reducing interfacial tension and maintaining stable surface activity in various complex systems.

The most notable feature of this product is its "multifunctional integration": it possesses the emulsifying and wetting capabilities of traditional nonionic surfactants, while its weakly cationic nature gives it a natural affinity for negatively charged surfaces. It can form adsorption films on substrates such as metals and fibers, providing additional functions like antistatic, corrosion inhibition, and softening conditioning. This characteristic is relatively rare among similar products, often allowing it to replace multiple single-function additives in formulations.

In addition, AC-1210 maintains good activity in both acidic and alkaline media, with outstanding hard water resistance and low tendency to form precipitates with calcium and magnesium ions. This ensures its reliability in complex water quality conditions and a wide pH range, making it particularly suitable for industrial formulation systems with stringent stability requirements.

Application Suggestions

Based on its comprehensive characteristics, AC-1210 has outstanding application value in the following fields:

  • Textile Dyeing and Finishing: As a core component of acid dye leveling agents, it controls dyeing rate to avoid color spots; also serves as an antistatic finishing agent for synthetic fibers.
  • Metalworking: In cutting fluids, rust preventives, and cleaners, it combines emulsifying, corrosion inhibition, and lubrication functions; its weakly cationic property allows it to form a protective film on metal surfaces.
  • Daily Chemical Products: In shampoos and conditioners, it provides conditioning effects, improves combing and softness, while reducing formulation irritation.
  • Pesticide Formulations: As an emulsifier and synergist, it enhances the wetting, spreading, and penetration of pesticide liquids on plant leaf surfaces, particularly suitable for glyphosate and other herbicide formulations.
  • Industrial Cleaning: In high-temperature and high-pressure cleaning formulations, it effectively removes heavy oil stains and carbon deposits, and provides corrosion inhibition protection in acidic systems.

Precautions

  • The product is irritating to skin and eyes (hazard category 2). Protective gloves and goggles must be worn during handling.
  • It has chronic toxicity to aquatic life (H412). Do not discharge directly into water bodies. Waste must be disposed of in accordance with environmental regulations.
  • Recommended storage temperature: 5~40°C. Keep away from strong oxidizers and strong acids. Keep container tightly closed. Shelf life up to two years.
