| Regulatory Status | REACH compliant |
| Handling Precautions | Use gloves & goggles; avoid strong acids |
Summary
This ethoxylated amine surfactant combines a linear alkyl chain with adjustable ethylene oxide (EO) units, allowing tunable hydrophilicity for diverse applications. Its low irritation and controllable foaming make it suitable for detergents, agrochemicals, and personal care. Performance varies significantly with EO number, enabling customized formulations.
