Nonylphenol Ethoxylate NP-10
CAS Number: 9016-45-9
Nonylphenol ethoxylate NP-10 is a nonionic surfactant with 10 ethylene oxide units, widely used as a co-emulsifier and stabilizer in emulsion polymerization. It provides steric stabilization to latex particles, improving freeze-thaw and shear stability. Due to APEO environmental regulations, NP-10 is increasingly substituted by alkyl polyglucosides or alcohol ethoxylates in regulated markets.
