Features Of Hampton NPE-7 Nonylphenol Ethoxylate Surfactant

  1. Optimized hydrophilic-lipophilic balance (HLB ≈ 7.0) for effective emulsification and wetting in low-water systems.

  2. High solubility in aromatic and chlorinated hydrocarbons, enabling stable formulations in industrial cleaning and metalworking fluids.

  3. Excellent low-foaming performance—ideal for high-shear and recirculating applications where foam control is critical.

  4. Good thermal and hydrolytic stability across a broad pH range (pH 4–11), supporting robust process compatibility.

  5. Efficient grease and oily soil removal with rapid penetration into complex substrates including metals, plastics, and painted surfaces.

Typical Applications Of Hampton NPE-7 Nonylphenol Ethoxylate Surfactant

  1. Industrial cold-cleaning and vapor-degreasing formulations for precision metal parts.

  2. Emulsifier in solvent-based metalworking fluids and cutting oil concentrates.

  3. Wetting and dispersing agent in agricultural adjuvant systems for oil-soluble active ingredients.

  4. Key component in heavy-duty industrial detergents for engine degreasing and maintenance washes.

  5. Stabilizer in polymer emulsion synthesis and pigment dispersion for coatings and inks.
