Octadecylamine Polyoxyethylene Ether AC-1820 (CAS: 26635-75-6) is a nonionic surfactant starting from octadecyl fatty amine, featuring a unique pH-dependent ion conversion property—it remains nonionic under neutral and alkaline conditions but protonates to a cationic state under acidic conditions. This dual characteristic plays a key role in complex formulation systems across multiple industries.
Based on authoritative data from the Guoli Chemical product database, the core applications of this product cover the following industries and process scenarios.
| Industry | Specific Process/Use | Functional Role |
|---|---|---|
| Textile Printing and Dyeing | Level dyeing of acid dyes (wool, nylon, and blended fabrics) | Controls dye uptake rate, prevents color spots, improves levelness and color fastness |
| Agrochemicals | Formulation of pesticide emulsifiable concentrates, oil-in-water emulsions, and microemulsions | Efficient emulsifier, enhancing emulsion stability and liquid spreading |
| Industrial Cleaning | Cleaning of metal parts and textile machinery (acidic/neutral systems) | Emulsifying, dispersing, penetrating, removing oil, wax, and carbon deposits |
| Metalworking | Cutting fluids, grinding fluids, and other metalworking fluids | Corrosion inhibitor, forms a protective film, provides lubrication and anti-rust properties |
| Synthetic Materials | Antistatic treatment of polyester, acrylic, and plastic products | Reduces surface resistance, forms a conductive layer, dissipates static charges |
| Mineral Processing | Flotation of non-polar minerals | Selective collector/foaming aid, improves bubble attachment |
| Road Construction | Preparation of emulsified asphalt | Asphalt emulsifier, produces cationic/nonionic emulsified asphalt |
In acidic dye baths, utilize its cationic property to enhance affinity for fibers; in pesticide formulations, it is recommended to combine with anionic emulsifiers to improve formulation stability; in metalworking applications, the recommended dosage should be verified through small-scale tests based on water hardness and processing conditions.
