Nonylphenol

Nonylphenol (CAS 25154-52-3), abbreviated NP, is an alkylphenol intermediate used in industrial manufacturing as a precursor to surfactants, antioxidants and polymer stabilizers.

Where is Nonylphenol used?

• Textile and leather: reacted with ethylene oxide into nonylphenol ethoxylates acting as emulsifiers and wetting agents in dyeing and finishing baths
• Plastics and rubber: NP-derived antioxidants protect polymer compounds from thermal and oxidative degradation
• Metalworking and lubricants: NP-based additives aid emulsion stability in cutting fluids and corrosion-inhibiting packages
• Printing and packaging: NP derivatives serve as dispersants and emulsifiers in ink and coating systems
• It is a foundational building block for ethoxylated derivatives and other downstream chemical products.

Good to know: Buyers should confirm isomer composition, as this affects downstream reactivity.

Commercial specifications

• Purity typically 99% or above
