Product Category: Industrial Surfactants / Detergent Raw Materials
Chemical Type: Nonylphenol Ethoxylate
Alternative Names: NP6 / NPE-6 / Nonyl Phenol Ethoxylate 6EO
Surfactant Type: Non-ionic
Appearance: Typically pale liquid
Product Overview
NP6 is a non-ionic nonylphenol ethoxylate containing approximately six moles of ethylene oxide.
Compared with higher-ethoxylated NP grades such as NP9, NP6 is more oil-compatible and has a lower hydrophilic-lipophilic balance, making it particularly useful as a coupling agent, emulsifier and low-foaming surfactant.
Typical Technical Characteristics
| Property | Typical Reference |
| SKU | MCS-N4 |
| Chemical Family | Nonylphenol Ethoxylate |
| Ethoxylation | Approx. 6 EO |
| Ionic Character | Non-ionic |
| HLB | Approx. 10.9 |
| Typical Cloud Point | Below approximately 25°C |
| Physical Form | Liquid |
| Primary Function | Emulsifier / coupling agent |
| Foaming Character | Relatively low foaming |
A commercial NP6 reference identifies it as POE(6) nonylphenol with an HLB around 10.9 and use as a coupling agent and water-in-oil emulsifier.
