Nonylphenol ethoxylates (NPEs), also referred to as nonylphenol polyethoxylates or nonoxynols, are a class of nonionic surfactants with broad industrial applicability. They are synthesized via the ethoxylation reaction of nonylphenol and ethylene oxide, with the number of ethylene oxide (EO) units (denoted as\u00a0n) determining their physical and chemical properties.<\/p>\n
