The core characteristic of Stearylamine Polyoxyethylene Ether AC-1802 is its "switchable ionic property" — it is non-ionic in neutral/alkaline conditions and converts to cationic in acidic conditions, offering excellent emulsifying, dispersing, antistatic, and softening conditioning functions.
Six Core Properties
- Switchable Ionic Property: Exhibits non-ionic behavior in neutral and alkaline environments, providing wide chemical compatibility; in acidic systems, the amine group protonates to become cationic, significantly enhancing adsorption capacity on negatively charged substrates.
- Outstanding Emulsifying Ability: Demonstrates remarkable emulsification for various oils and organic solvents, forming stable O\/W or W\/O emulsion systems at low dosages, with an HLB value of approximately 4.5.
- Excellent Dispersing Performance: Effectively disperses solid particles, preventing agglomeration and sedimentation, especially outstanding in pigment and mineral systems.
- Superior Chemical Stability: Resistant to acids, bases, and hard water, maintaining stable performance over a wide pH range, suitable for complex industrial environments.
- Good Antistatic Property: The molecular structure imparts durable antistatic effects, particularly suitable for surface treatment of polymer materials.
- Excellent Softening and Conditioning Function: Forms a lubricating film on fiber and hair surfaces, providing a soft and smooth feel.
