Product Description
Ethoxylated nonylphenols are nonionic surfactants obtained from the addition of ethylene oxide gas to nonylphenol. Ethoxylated nonylphenol is named NPE followed by the number of ethylene oxide gas added.
NPE2, NPE3, NPE4, NPE5, NPE6, NPE9, NPE10 are viscous liquids, NPE12, NPE15 are high-viscosity liquids at room temperature, and higher grades are white waxy solids. Other grades of NPE are available upon request.

Bulk or 220 liter barrels (200 kg net), each 4 barrels packed in one pallet.
Shelf life, 24 months and in covered storage.
Different grades of NPE generally do not present significant problems in handling and storage. They are not volatile or corrosive compounds. They are stable materials with a high flash point. For long-term storage of bulk liquids, 304/316 steel tanks are recommended under nitrogen gas conditions. Storage conditions at 20-30 degrees Celsius are recommended.
In detergents: ethoxylated nonylphenols are used in solid and liquid detergents, dishwasher liquid and glass cleaners.
In textile: as primary wool cleaner, as emulsifier, antistatic and lubricant.
In agriculture: as an emulsifier
In latex and waxes: as a water-soluble emulsifier
In fat, oil: as an emulsifier
