Dodecylamine Polyoxyethylene Ether AC-1210, with the full chemical name Polyoxyethylene (10) Dodecyl Ether (also known as AEO-10, C12E10, PEG-10 Lauryl Ether), is a specialty surfactant produced by Haian Guoli Chemical Co., Ltd. This product is synthesized by reacting dodecyl primary amine with ethylene oxide. Its molecular structure contains both a hydrophilic polyoxyethylene ether chain and a long-chain alkyl hydrophobic group, while retaining the weakly cationic character of the tertiary amine group. At room temperature, it appears as a colorless to slightly yellow liquid, readily soluble in water and various organic solvents, and belongs to the nonionic surfactant category.
Due to its unique molecular design, AC-1210 exhibits excellent interfacial activity and broad compatibility. It can be compounded with various types of surfactants, including nonionic, anionic, cationic, and amphoteric ones, maintaining stable surface activity in both acidic and alkaline media. It has outstanding hard water resistance and is not prone to precipitation with calcium and magnesium ions in water. Its weakly cationic nature also imparts affinity to negatively charged surfaces (such as metals, fibers, and plant leaves), providing additional functions like antistatic, softening, conditioning, and corrosion inhibition.

Textile Dyeing and Finishing: As a core component of leveling agents for acid dyes, the recommended dosage is 0.5%~2% of the working solution, effectively improving dyeing uniformity and color yield. When used as an antistatic finishing agent for synthetic fibers, the recommended dosage is 1~3 g/L. Its low-foam property makes it especially suitable for high-speed jet dyeing equipment.
Metalworking: In metal cutting fluids and cleaning agents, the recommended addition amount is 2%~8% of the total formulation, providing triple functions of emulsification, corrosion inhibition, and lubrication. The corrosion inhibition effect is particularly pronounced in acidic media.
Daily Chemical Products: As a conditioning agent and thickener in shampoos and body washes, the recommended dosage is 0.5%~3%, improving wet combing smoothness and foam fineness while reducing formulation irritation.
Agrochemical Formulations: As an emulsifier and penetration enhancer, the recommended dosage in emulsifiable concentrates or oil-in-water emulsions is 3%~10%, significantly enhancing the wetting and spreading ability of the spray solution on plant leaves. It is particularly suitable for herbicides such as glyphosate.
Industrial Cleaning: Used in heavy oil stain cleaning and high-temperature high-pressure cleaning scenarios, the recommended addition amount is 5%~15%. In acidic cleaning formulations, it also provides equipment corrosion protection.
