Nonylphenol Ethoxylate (NPE) Types
Key differences between NPE-9、NPE-9.5、NPE-6、NPE-10、NPE-30:
The number after “NPE” indicates the average number of ethylene oxide (EO) units added to the molecule.
Smaller number → more oil‑soluble (lipophilic)
Larger number → more water‑soluble (hydrophilic)
| Grade | EO Units | Key Characteristic | Typical Use |
| NPE‑6 | ~6 | More oil‑soluble, strong emulsifier | Industrial cleaning, oil and grease removal |
| NPE‑9 | ~9 | Balanced HLB (most popular all‑purpose grade) | General emulsifier, detergents, textile processing |
| NPE‑9.5 | ~9.5 | Very similar to NPE‑9, fine‑tuned performance | Formulation replacement or adjustment |
| NPE‑10 | ~10 | Slightly more water‑soluble | Textile wetting, laundry detergents |
| NPE‑30 | ~30 | Highly water‑soluble | Special emulsification, dispersion applications |
Which Grade Is Most Common?
NPE‑9 is the most widely used grade.
- Balanced hydrophilic‑lipophilic properties (suitable HLB value)
- Strong versatility across many applications
- Good cost‑performance ratio
Nonylphenol Ethoxylate (NPE) for Sale
Excellent Emulsifier & Wetting Agent: NPE is an outstanding emulsifier for oils, fats, and organic solvents. It also acts as a superior wetting agent, allowing water-based solutions to spread and penetrate surfaces, ensuring better cleaning or dyeing uniformity.
Powerful All-Purpose Detergency: It is a high-performance detergent, effective at removing grease, soil, and stains. It serves as the main active component in both household laundry detergents and powerful industrial degreasers.
Excellent Chemical Stability: This product demonstrates excellent chemical stability, remaining highly effective in strong acids (like metal pickling baths) and strong alkalis, even at high temperatures.
Excellent Hard Water Tolerance & Solubility: NPE performs reliably in hard water conditions. It also shows excellent solubility in a wide range of solvents, making it ideal for formulations with challenging water chemistries.
Wide HLB Range & Broad Applicability: Available across multiple ethoxylation grades (from NPE-4 to NPE-30), you can easily select the exact balance of hydrophilic-lipophilic properties needed for your specific application.
What is Nonylphenol Ethoxylate (NPE) Used for
Industrial Cleaning & Degreasing: Used in heavy‑duty industrial cleaners, metal degreasers, and oil spill treatments. Effectively removes oil, grease, and wax from surfaces.
Textile Processing: Acts as a wetting agent, scouring agent, and dye leveler in textile manufacturing. Improves fabric penetration and dye uniformity.
Pesticide & Agrochemical Formulations: Serves as an emulsifier and dispersant for pesticide concentrates, helping oil‑based active ingredients mix with water for spraying.
Paper & Pulp Industry: Used as a de‑inking agent and dispersant in paper recycling and during pulp processing to improve fiber separation and cleaning.
Emulsion Polymerization: Functions as an emulsifier in the production of polymers, resins, and latexes (e.g., acrylics, styrene‑butadiene). Helps stabilize polymer particles during synthesis.
FAQ of Nonylphenol Ethoxylate (NPE)
NPEs are generally of low acute toxicity. However, they can be harmful if swallowed or in contact with skin, and they may cause serious eye damage.
Nonylphenol ethoxylate (NPE) is generally considered a dangerous good during export shipments. For safe and compliant export, HOO CHEMTEC provides a full range of dangerous goods documentation, including Material Safety Data Sheets (MSDS) and UN packaging certification, to ensure your shipment arrives safely and on time.
Most orders ship within 7-10 days to China port. Full export documentation — CoA, MSDS, packing list, commercial invoice — provided with every order.
Yes. Our technical team provides free formulation support to help you select the right NPE grade, optimize dosage, and achieve target performance in your application.
Our NPE is typically supplied in 215KG/DRUM or 1000KG/IBC to ensure easy handling and convenient transport.
Store NPE in a cool, dry, and well-ventilated area with containers tightly sealed to prevent moisture absorption and maintain product quality.
