According to the technical data from Guoli Chemical, compared to similar products, the core advantages of Octadecylamine Polyoxyethylene Ether AC-1812 lie in its **higher effective content (≥99%), unique dual nonionic/weak cationic characteristics, excellent hard water resistance and acid-alkali stability, as well as its efficient performance integrating multiple functions such as emulsification, dispersion, leveling, and antistatic properties**.
### Detailed Explanation
The outstanding performance of AC-1812 in industries such as textiles, plastics, and pesticides is mainly attributed to the following characteristics:
1. **Ultra-high Effective Content**: The product from Guoli Chemical boasts an effective content of **≥99%** and a moisture content of **≤0.5%**. This means it contains minimal impurities and extremely high active components, achieving excellent results at low dosages, thus offering better cost performance.
2. **Dual Ionic Characteristics**: As a nonionic surfactant, it is compatible with various anionic and cationic auxiliaries. Additionally, its tertiary amine structure protonates under acidic conditions, exhibiting cationic characteristics, allowing it to firmly adsorb onto negatively charged fibers, plastics, or metal surfaces—an advantage not found in many ordinary nonionic surfactants.
3. **Hard Water Resistance and High Cloud Point**: It maintains stable performance in hard water without interference from calcium and magnesium ions. Its 1% aqueous solution has a cloud point of **≥90℃**, fully meeting the requirements for high-temperature (above 130℃) and high-pressure dyeing processes of polyester, whereas many similar products tend to precipitate or fail at high temperatures.
4. **Low Foaming Characteristic**: Being a low-foam product, it offers significant advantages in industrial circulating water, textile dyeing, and other processes requiring rapid water passage, effectively reducing problems caused by foam.
5. **Multifunctional Integration**: One product provides multiple functions simultaneously, not only simplifying formulations but also avoiding potential conflicts among various auxiliaries, thus reducing overall formulation costs.
### Core Advantage Data Comparison
The following is a comparison of performance based on the technical parameters of AC-1812 with common ordinary dodecylamine polyoxyethylene ether (1215) types or other ethoxylated amine products with lower content on the market:
| Performance Indicator | **Guoli Chemical AC-1812** | Ordinary Similar Products |
| :--- | :--- | :--- |
| **Effective Content** | **≥99%** | Usually 95% or lower |
| **Ionic Characteristics** | Nonionic/Cationic under acidic conditions (dual characteristics) | Mostly purely nonionic |
| **1% Aqueous Solution Cloud Point** | **≥90℃** | Some products below 80℃, unstable at high temperatures |
| **Tertiary Amine Content** | **≥95%** | Some products contain more primary/secondary amine impurities, affecting performance |
| **Hard Water Resistance** | Excellent, unaffected by calcium and magnesium ions | Some products may precipitate or have reduced effectiveness in hard water |
| **Foaming Characteristics** | Low foam | Medium to high foam, may affect processes and cleaning |
| **Main Application Functions** | Leveling, antistatic, emulsification, dispersion, corrosion inhibition in one | Relatively single function, difficult to cover multiple aspects |
### Application Recommendations
Based on the above advantages, AC-1812 performs particularly well in the following applications:
- **Textile Dyeing and Printing (Recommended dosage: 1~3 g/L)**: As a high-temperature and high-pressure leveling agent for polyester/acrylic blended fabrics, it effectively solves dyeing issues like color spots and uneven dyeing, while imparting good hand feel to the fabric.
- **Plastic Antistatic (Recommended addition amount: 0.5%~2%)**: As an internal antistatic agent, it quickly migrates to the surface in materials like PP and PE, providing long-lasting and stable antistatic effects.
- **Pesticide Emulsification (Recommended dosage: 5%~10%)**: As an emulsifier in emulsifiable concentrates or microemulsions, it adapts to different water qualities and ensures long-term stability of the pesticide formulation.
- **Metalworking Cleaning (Recommended dosage: 2~5 g/L)**: In acidic cleaners, it exhibits excellent corrosion inhibition and penetration effects, protecting metal workpieces.
### Precautions
During use, leverage its dual characteristics of being nonionic and cationic under acidic conditions. To enhance its cationic adsorption function, adjust the system pH to acidic. For storage, keep it sealed and stored in a cool, dry place, preferably at temperatures below 35℃.
