The specific usage of dodecylamine polyoxyethylene ether AC-1202 varies significantly depending on the application field. The recommended addition amount should be determined through experiments based on the formulation system and process requirements. The product database currently does not contain standard addition amount data for each application scenario. The following provides general industry usage guidelines for reference.

Detailed Description

Dodecylamine polyoxyethylene ether AC-1202 (also known as lauryl alcohol polyoxyethylene (2) ether, AEO-2) is a nonionic surfactant with an HLB value of 6, insoluble in water but soluble in organic solvents. Its molecular structure contains 2 ethoxy (EO) units, making it strongly lipophilic. Therefore, in pretreatment formulations, it typically needs to be compounded with high-HLB emulsifiers to achieve ideal emulsification and dispersion effects. The product can exhibit cationic properties in acidic media, possessing dual functions of both nonionic and cationic surfactants.

Before use, fully understand the phase behavior and target performance of the formulation. Due to its strong lipophilicity, when preparing water-based systems, first thoroughly mix AC-1202 with the oil phase or solvent phase, then slowly add the water phase while stirring. If necessary, auxiliary heating (recommended not exceeding 40°C) can be used to reduce material viscosity and improve mixing efficiency. This product is a low-foaming type, especially suitable for industrial applications sensitive to foam, such as circulating spray cleaning and metalworking fluid systems.

In industrial formulations, this product is often used as an auxiliary emulsifier or co-surfactant. When compounded with high-HLB nonionic surfactants (such as AEO-9, TX-10, etc.) or anionic surfactants, it can significantly improve the emulsion stability and penetration of the formulation. It is recommended to conduct small-scale compounding experiments before formal production to determine the optimal addition ratio and process conditions.

Application Suggestions

Pesticide Emulsifier: Used as an auxiliary emulsifier, typically compounded with high-HLB emulsifiers (such as agricultural emulsifier 600# series). In emulsifiable concentrate formulations, the recommended addition amount is generally 2%~8%, which should be optimized based on the type of active ingredient and solvent system. When preparing microemulsions or oil-in-water emulsions, this product helps improve low-temperature emulsion stability.

Industrial Cleaners: Suitable for solvent-based or semi-aqueous cleaning formulations. Leveraging its excellent wetting and penetration capabilities, it effectively removes heavy oil stains and metalworking residues. It is recommended to compound with anionic surfactants, with addition amount generally adjusted in the range of 3%~10%. Note that this product is insoluble in water and must be pre-dissolved in the oil phase or solvent phase.

Metalworking Fluids: Used as an emulsifier and lubricity additive in cutting fluid and grinding fluid formulations to improve the extreme pressure lubrication performance of the working fluid. Recommended addition amount is 1%~5%, with better results when used in combination with other rust inhibitors and extreme pressure additives.

Leather Degreasing Agent: This product can quickly penetrate the fat layer of raw hide to achieve uniform degreasing. Recommended addition amount is 3%~8%, and it can be compounded with nonionic or anionic surfactants to enhance degreasing efficiency.

Textile Antistatic Agent/Softener: Used for finishing synthetic fibers, recommended usage concentration is 0.5%~3%, applied through padding or dipping processes. Under acidic conditions, it can exhibit cationic properties, enhancing adsorption onto fibers.

Paint Dispersant: Used as a pigment wetting and dispersing agent, recommended addition amount is 0.5%~2% based on pigment weight. It stabilizes pigment dispersion through steric hindrance effects to prevent flocculation.

Note: The above addition amount data is derived from general industry experience and is not an official recommendation from the Guoli Chemical product database. The actual addition amount should be determined based on experimental verification results.

Precautions

  • This product is insoluble in water. It must be thoroughly mixed with the oil phase or solvent phase before use and should not be added directly to the water phase.
  • The cloud point is below 20°C. When used in water-based high-temperature systems, cloudiness or phase separation may occur; attention should be paid to process temperature control.
  • The HLB value is only 6. When used alone, emulsifying ability is limited. It is recommended to compound with high-HLB emulsifiers to achieve optimal performance.
  • During operation, it is recommended to wear chemical safety goggles and impermeable gloves, and keep the work area well-ventilated.
  • Store at a temperature between 5~35°C, avoid high temperatures and direct sunlight. Seal tightly after opening.
