Dodecyl polyoxyethylene ether AC-1215 (CAS No.: 26635-75-6) is a colorless to light yellow transparent liquid at room temperature, easily soluble in water and various organic solvents. Its usage method is very simple: in industrial formulation production, it is usually directly added as an auxiliary component to the mixing system and stirred evenly to function. When formulating textile printing and dyeing auxiliaries, it can be added to the working solution for circulation; in pesticide formulations, it is often used as an emulsifying dispersant during the mixing process of oil and water phases; in daily chemical products, it is generally added during the heating and stirring stage of the aqueous phase to synergize with other surfactants.
The core characteristic of this product lies in its molecular structure containing both tertiary amine groups and polyoxyethylene ether segments (EO number approximately 15). This not only provides excellent emulsifying, wetting, and dispersing capabilities of nonionic surfactants, but also transforms into a cationic surfactant in acidic media due to the protonation of amine groups, thus imparting additional functions such as antistatic properties, softening, and conditioning. With an HLB value of approximately 15.6 and a cloud point >100°C, it maintains stable performance under high temperature and a wide pH range.
As a mature product of Guoli Chemical, AC-1215 has been widely used in industries such as textile printing and dyeing, pesticide formulations, industrial cleaning, daily chemical care, and metalworking fluids, with advantages including hard water resistance, acid and alkali resistance, and flexible compatibility.

The following are typical recommended dosages of dodecyl polyoxyethylene ether AC-1215 in various major application fields (dosage should be optimized through experiments based on specific formulation and working conditions):
| Application Field | Function | Recommended Dosage (weight percentage of total formulation) |
|---|---|---|
| Textile Printing & Dyeing Leveling Agent | Improve dyeing uniformity, reduce color spots | 1%~3% |
| Textile Antistatic Agent | Reduce fiber surface resistance | 0.5%~2% |
| Pesticide Emulsifiable Concentrate/Emulsion in Water | Emulsify and disperse, improve formulation stability | 3%~8% |
| Industrial Hard Surface Cleaner | Solubilization, wetting, penetration | 1%~5% |
| Daily Chemical Hair Care Products (Shampoo, Conditioner) | Antistatic, conditioning | 0.5%~2% |
| Metalworking Fluids (Cutting Fluid, Rust Preventive Fluid) | Emulsify, rust prevention | 2%~5% |
| Acidic System Compatibility Improver | Enhance compatibility, prevent stratification and precipitation | 1%~3% |
Note: The above dosages are industry general reference ranges (data source: Guoli Chemical product database and industry application experience). Actual optimal dosage should be determined through small-scale and pilot experiments. In acidic formulations, the cationic characteristics of AC-1215 will be enhanced, and the dosage can be appropriately reduced.
