Nonylphenol Ethoxylate (NPE) is a series of nonionic surfactants produced by the ethoxylation of nonylphenol. Different EO mole numbers provide different HLB values, cloud points and solubility, making NPE suitable for industrial cleaning, textile auxiliaries, coatings, agrochemicals and other industrial applications.
Backed by more than ten years of experience in NPE production and supply, Dotachem offers a broad range of Nonylphenol Ethoxylate grades, including NP-2, NP-4, NP-6, NP-9, NP-10 and higher EO grades up to NP-50. As a China-based NPE supplier, Dotachem can provide liquid, solid or flake forms according to grade characteristics, formulation needs, storage conditions and handling requirements.

Wide EO Mole Range
Dotachem supplies multiple NPE grades. Lower EO grades are more oil-soluble, while higher EO grades offer greater water compatibility.
Adjustable HLB
The EO mole number determines HLB and influences wetting, emulsification, detergency and dispersion, allowing selection for different formulation needs.
Grade-Dependent Physical Form
Depending on EO level and temperature, NPE may be supplied as a liquid, paste, solid or flake to suit different feeding and processing methods.
Practical Surfactant Performance
Nonylphenol Ethoxylate provides effective wetting, emulsification, dispersion and cleaning in industrial detergents, textile processing and related formulations.
Industrial Detergents and Cleaning Products
Used in heavy-duty cleaners, metal degreasers and equipment cleaning products for wetting, emulsification and oil removal.
Textile Auxiliaries

Nonylphenol Ethoxylate should be stored in a cool, dry and well-ventilated place. Keep the container tightly closed when not in use, and avoid direct sunlight, strong oxidants and incompatible materials.
During handling, operators should follow the product SDS and use suitable protective measures according to local safety requirements. For long-term storage or bulk inventory, customers are advised to check the product condition before use.
Yes. Dotachem provides free samples for product evaluation before bulk purchasing. Customers can contact us with their application and delivery information to request a sample.
Dotachem can provide COA, SDS and TDS according to the selected product grade. If customers have additional document requirements for import, internal approval or quality review, they can confirm them with our team before shipment.
It depends on the formulation system. Some medium EO grades may be used across detergents, textile auxiliaries and emulsifier systems, but the same grade may not perform equally well in every formula. Testing is recommended when changing application, dosage or processing condition.
Yes. Besides NPE, Dotachem also supplies related surfactants and chemical products such as AEO, PEG, SLES and other functional additives. We can support formulation discussion, product matching, sample evaluation and one-stop sourcing for customers who need multiple raw materials.
