4-Isononylphenol

4-Isononylphenol (CAS 26543-97-5) is an alkylphenol intermediate used in the production of nonionic surfactants, particularly ethoxylated derivatives that drive emulsification and wetting performance.

It functions primarily as a building block rather than a finished surfactant, making it a procurement target for formulators producing cleaning agents, emulsifiers, and surface-active systems.

In home care and industrial cleaning, it serves as a precursor to ethoxylates used in heavy-duty degreasers and hard-surface cleaners where robust soil removal is required for industrial applications.

Textile and leather processors rely on ethoxylated derivatives produced from this compound for scouring, dyeing auxiliaries, and finishing baths to ensure high-quality material processing and consistency.

In coatings and adhesives, it contributes to emulsifier systems that stabilize resin dispersions and improve substrate wetting. Polymer manufacturers use it as a reactive intermediate or modifier.

This chemical is essential where controlled surface activity is needed in the production process. 4-Isononylphenol is supplied as a liquid at ambient conditions for ease of handling and storage.

Technical grade is the standard commercial form, with purity specifications typically ranging from 95% upward depending on the intended downstream synthesis and specific industrial requirements.

Bulk quantities are available in drums and IBC containers, with packaging suited to industrial-scale formulation and chemical synthesis operations across various global manufacturing sectors.
