Nonylphenol Ethoxylate-10, chemically known as nonylphenol polyoxyethylene ether, is a typical nonionic surfactant. It is prepared by the addition reaction of nonylphenol and ethylene oxide under alkaline conditions, with an ethylene oxide addition number of 10.
It appears as a colorless, transparent liquid with an active ingredient content ≥99%, a cloud point of 60-67℃, and excellent hydrophilic emulsifying properties.

Nonylphenol Ethoxylate-10 is widely used as an emulsifier and dispersant in:
In asphalt emulsification, it can react with epichlorohydrin and triethylamine to synthesize cationic emulsifiers for preparing slow-cracking and fast-cracking emulsified asphalt. The finished product exhibits good storage stability and is widely used in asphalt road and bridge engineering.
