According to the technical data of Guoli Chemical, the core advantage of fatty amine polyoxyethylene ether AC-1860 over similar products lies in its **excellent functional compositeness and stability under extreme conditions**. By virtue of its extremely high ethylene oxide (EO) addition number, it perfectly balances strong emulsifying power, high dispersibility, and resistance to acid, alkali, and hard water.
Detailed Explanation
Compared to other fatty amine polyoxyethylene ether series products in the database (such as AC-1830, AC-1820, AC-1815, AC-1812, AC-1810, AC-1802), the biggest difference of AC-1860 is the high ethylene oxide (EO) addition number of 60 in its molecular structure, which is the highest among all models. This structural difference directly gives it the following unique advantages:
1. **Stronger hydrophilicity and water solubility**: The high EO number makes AC-1860 dissolve faster in cold water, resulting in a clearer solution with less gel formation, making it more convenient to prepare working fluids.
2. **Better electrolyte and hard water resistance**: In industrial environments containing high concentrations of salt, acid, alkali, or hard water, the stability of AC-1860 far exceeds that of similar products with low EO numbers. It is less prone to problems such as "salting out" failure, making it especially suitable for harsh conditions like metalworking fluids and pretreatment in dyeing and finishing.
3. **Excellent dispersion and leveling ability**: In high-temperature and high-pressure dyeing processes, the long EO chain of AC-1860 provides stronger steric hindrance effects. Its ability to disperse, retard, and migrate dye aggregates is more prominent than that of low-EO models, effectively preventing dye defects such as color spots and uneven coloring.
4. **Mildness and low foaming property**: As the EO number increases, the skin irritation of the product is usually lower, and foam is more controllable and easy to rinse off, making it perform excellently in industrial cleaning agent formulations.
Specific Data
Technical Parameter Comparison (Based on Guoli Chemical Series Products)
| Product Model | EO Addition Number | Appearance (Room Temperature) | Hydrophilicity | Core Advantages |
| :--- | :--- | :--- | :--- | :--- |
| **AC-1860** | **60** | **Light yellow to yellow-brown solid/paste** | **Extremely high** | **Ultra-strong dispersion, electrolyte resistance, high-temperature leveling** |
| AC-1830 | 30 | Light yellow to yellow | High | Balanced comprehensive performance, versatile antistatic agent/leveling agent |
| AC-1820 | 20 | Pale yellow to yellow | Medium-high | Balanced leveling and emulsification, commonly used as leveling agent |
| AC-1815 | 15 | Pale yellow | Medium | Good emulsification and wetting, common textile auxiliary |
| AC-1812 | 12 | Light yellow to yellow | Medium-low | Strong wetting and emulsifying power, with antistatic properties |
| AC-1810 | 10 | Light yellow to yellow waxy solid | Low | Excellent emulsification and wetting ability |
| AC-1802 | 2 | White to slightly yellow waxy solid | Extremely low | Efficient water-in-oil (W/O) emulsifier |
From the table above, it can be seen that AC-1860, with its extremely high EO number, achieves a leap in hydrophilicity and stability.
Application Suggestions
AC-1860 is the ideal solution when you face the following situations in your applications:
- **High-temperature and high-pressure dyeing**: For dyeing nylon and its blends, the recommended dosage is 1-3 g/L, which can effectively prevent streaks and uneven coloring.
- **High-concentration electrolyte systems**: For example, in metal cutting fluids and alkaline degreasers, it can serve as a long-term stable emulsifying and dispersing component, resistant to layering.
- **Water-based paints and inks**: For dispersing organic pigments or fillers, the recommended addition amount is 5%-20% of the pigment weight, providing high color development and storage stability.
- **Pesticide emulsion in water (EW)**: As an emulsifier, its strong hydrophilicity and electrolyte resistance help prepare stable and transparent microemulsions.
Precautions
1. AC-1860 appears as a solid or paste. It is usually necessary to heat it to melt or dissolve it in hot water before use to obtain a uniform solution.
2. In product design, low EO numbers (such as AC-1802) tend to be water-in-oil emulsifiers, while high EO number AC-1860 is a typical oil-in-water emulsifier. Their functional positioning is vastly different, and they cannot be simply substituted.
3. For safe operation, its potential skin and eye irritation (H315/H319) should still be noted. It is recommended to wear goggles and gloves during operation.
