Nonyl Phenol 4 EO is an oil-soluble surfactant with excellent emulsification properties at low HLB (HLB: 8.9)
This property helps Nonyl Phenol 4 EO to remove dirt when added to the cleaner formulations.
Nonyl Phenol 4 EO is a Nonyl Phenol Ethoxylate (NPE) Surfactant.
Nonyl Phenol 4 EO is a nonionic surfactant that decreases the surface or interfacial tension between two liquids.
Nonyl Phenol 4 EO is a non-ionic surface active agent for use in paints and coatings, paper and textile processing, cleaners and detergents, agrochemicals, and metalworking fluids, with excellent detergency, outstanding wetting, versatile solubility characteristics, and exceptional handling properties.
Nonyl Phenol 4 EO is used in large quantities as detergents, cleaning agents, emulsifiers, wetting agents, foaming agents, antistatic additives, or dispersants.
Nonyl Phenol 4 EO Surface Active Agent can be used in oilfield drilling and production formulations as a dispersant for petroleum oil, in-process cleaning, cleaners and degreasers, and dry cleaning.
Nonyl Phenol 4 EO is a nonionic surface active agent compatible with all other nonionic, anionic, or cationic substances.
Electrolytes, for example, neutral salts, alkalis, and – to a lesser extent – acids, reduce the water solubility of Nonyl Phenol 4 EO and may lead to their salting out, especially at high concentrations and temperatures
Nonyl Phenol 4 EO has excellent resistance to compounds that cause hard water to metal salts, including those of heavy metals, acids, alkalis, reductive agents, and oxidative agents based on peroxide.
