AC-1815 (CAS: 26635-75-6) is a special nonionic surfactant with both amine groups and polyoxyethylene chains in its molecule. It exhibits nonionic characteristics under neutral/alkaline conditions and can convert to a cationic form under acidic conditions. This unique ionic property conversion capability gives it irreplaceable process value in multiple industrial fields.
According to the product technical data from Hai'an Guoli Chemical Co., Ltd., the core functions of AC-1815 include: super emulsifying and dispersing ability, triple chemical resistance to acid, alkali, and hard water, excellent leveling and antistatic properties, and low-foam high-efficiency wetting characteristics. The following details its applications by industry and process.
| Industry | Specific Process/Use | Functional Role |
|---|---|---|
| Textile Printing and Dyeing | Leveling processes for acid dyes, reactive dyes, and cationic dyes | Leveling agent — migration and retardation dyeing, reducing color difference and streaks |
| Textile Printing and Dyeing | Antistatic treatment for synthetic fiber spinning and weaving | Antistatic agent — eliminating static buildup, reducing winding and breakage |
| Synthetic Fibers | High-speed spinning and stretching processes for polyester, acrylic, and nylon | Oil component — smoothing agent, bundling agent, reducing friction coefficient |
| Metal Processing | Emulsifying oils, semi-synthetic/synthetic cutting fluids, grinding fluids | Emulsifier — forming stable O/W or W/O emulsions |
| Metal Processing | Rust prevention processes for ferrous and non-ferrous metals | Corrosion inhibitor — surface adsorption film, isolating corrosive media |
| Agrochemicals | Pesticide formulations such as emulsifiable concentrates, aqueous emulsions, and microemulsions | Emulsifier — efficient emulsification for organophosphorus and pyrethroid technical materials |
| Daily Chemicals | Shampoos, body washes, conditioners formulations | Co-emulsifier, viscosity modifier, antistatic softener |
| Coatings and Inks | Dispersion processes for water-based/solvent-based coatings and printing inks | Pigment wetting and dispersing agent — deflocculation, preventing floating, flooding, and sedimentation |
In textile leveling processes, the recommended dosage is 0.5% to 2% of the dye bath ratio; under acidic conditions, its cationic characteristics can significantly enhance affinity for fibers. In metalworking fluids, the recommended addition is 3% to 8% of the concentrate; its cationic adsorption film can achieve both lubrication and rust prevention. In pesticide formulations, the recommended dosage as an emulsifier monomer is 5% to 15% of the total formulation, and it should be combined with anionic emulsifiers to achieve optimal HLB matching.
