Nonylphenol

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

It serves as a foundational building block for ethoxylated derivatives and other downstream chemical products rather than as a finished formulation ingredient for consumer applications.

In textile and leather processing, NP is reacted with ethylene oxide to produce nonylphenol ethoxylates, which function as emulsifiers and wetting agents in dyeing and finishing baths.

Plastics and rubber manufacturers use NP-derived antioxidants to protect polymer compounds from thermal and oxidative degradation during processing and end-use applications.

In metalworking and lubricant formulations, NP-based additives contribute to emulsion stability in cutting fluids and corrosion-inhibiting packages for industrial machinery.

Printing and packaging operations rely on NP derivatives as dispersants and emulsifiers in ink and coating systems to ensure consistent application and durability.

Nonylphenol is supplied as a liquid at ambient conditions and is available in bulk quantities including ISO tank, drum, and IBC formats for global distribution.

Technical grade is the standard commercial specification, with purity typically at 99% or above. Buyers should confirm isomer composition as this affects downstream reactivity.
