Dodecyl amine polyoxyethylene ether AC-1215 is a multifunctional nonionic surfactant, usually used in diluted form, can be directly dissolved in water or dispersed in organic solvents, and the specific usage varies depending on the application field.

Detailed Explanation

Dodecyl amine polyoxyethylene ether AC-1215 (CAS No.: 26635-75-6) appears as a colorless to light yellow transparent liquid at room temperature (above 25°C) and can be directly diluted and dispersed in water. Its 1% aqueous solution has a pH of 8-10, showing good water solubility. In acidic media, the amine group protonates, giving the product characteristics of a cationic surfactant. This property is particularly important in applications such as acidic cleaning and pickling, significantly enhancing the compatibilization and emulsification effects of the system.

When using, it is recommended to slowly add this product to water (or the aqueous phase) under stirring, rather than the reverse operation, to obtain a more uniform dispersion. For oil-based formulations, it can also be dispersed in various organic solvents. The product exhibits excellent resistance to hard water, acids, and alkalis, maintaining stable interfacial activity over a wide pH range. Therefore, whether in acidic, neutral, or alkaline formulation systems, AC-1215 can effectively perform emulsification, wetting, and dispersion functions.

As a special surfactant with both nonionic and cationic characteristics, AC-1215 has high formulation flexibility and can be compounded with other types of surfactants such as anionic, cationic, and nonionic to achieve synergistic effects. The specific dosage and blending ratio should be optimized through experiments based on the target formulation system and process requirements. When handling, wear protective gloves and goggles to avoid contact with skin and eyes.

Usage Suggestions for Various Application Fields

Application FieldSuggested Addition MethodReference Function
Textile Dyeing Leveling AgentAdd in diluted form to the dye bath, can be added before the dyeing process or simultaneously with the dyeLeveling, antistatic, reducing color difference and streaks
Pesticide Emulsifying DispersantAdd to oil phase or aqueous phase with stirring dispersion, used for formulating emulsifiable concentrates or water-based emulsionsReduce oil-water interfacial tension, improve emulsion stability
Industrial Hard Surface CleaningCompound with acidic/alkaline cleaning agents, directly add to the cleaning solution formulationSolubilization, wetting penetration, improving detergency efficiency
Daily Chemical Personal Care ProductsAdd as a conditioning component in shampoo, conditioner, and shower gel formulationsAntistatic, improve hand feel, reduce frizz
Metalworking FluidsAdd to cutting fluid or grinding fluid formulations, compound with other componentsEmulsification, rust prevention, lubrication
Acidic System Compatibilizing AgentDirectly add in acidic media, stir until uniformly dispersedImprove compatibility of components, prevent stratification and sedimentation

Operation and Dilution Suggestions

  • Dissolution Method: It is recommended to slowly add AC-1215 to water under stirring to avoid excessive foaming; for rapid dissolution, warm water at 30-50°C can be used to accelerate dispersion.
  • pH Adaptability: Stable in the pH range of 3-12 in nonionic state, exhibits cationic properties under acidic conditions, expanding application scenarios.
  • Storage Temperature: 5-35°C; at low temperatures, the product may become pasty or solidify. Before use, return to room temperature and stir evenly; product performance is not affected.
  • Compounding Suggestions: Can be compounded with various surfactants; it is recommended to conduct small-scale tests to verify compatibility and synergistic effects.
  • Specific Dosage: No fixed recommended dosage data is available; it must be determined through experiments based on the specific formulation system and process requirements.

Precautions

  • This product causes skin irritation and serious eye irritation (GHS hazard category 2). When handling, wear nitrile or neoprene protective gloves and splash-proof chemical goggles.
  • Harmful to aquatic life with long-lasting effects (H412). Do not discharge waste liquid containing this product directly into water bodies or sewers.
  • In case of skin contact, wash immediately with plenty of soap and water; if in eyes, rinse carefully with water for several minutes. If irritation persists, seek medical attention.
  • Avoid storage or mixing with strong oxidizing agents (peroxides, perchlorates, nitric acid, etc.) and strong acids.
  • The product is hygroscopic; immediately seal the container after use to prevent moisture ingress from affecting quality.
