Polyethylene glycol mono(4-nonylphenyl) ether

Polyethylene glycol mono(4-nonylphenyl) ether, identified by CAS 26027-38-3, is a nonionic surfactant used across industrial cleaning, textile processing, and agricultural formulations.

It functions primarily as an emulsifier, dispersant, and wetting agent, enabling oil-water compatibility in formulations where performance under varied pH and temperature conditions is required.

In industrial and institutional cleaning, it is formulated into hard-surface cleaners, degreasers, and laundry detergents where strong soil emulsification and low-foam profiles are needed.

Textile processors use it as a scouring and wetting agent to improve fiber penetration during dyeing, desizing, and finishing operations to ensure high-quality results.

In agriculture, it acts as an emulsifier and spreading agent in pesticide and herbicide formulations, improving active ingredient distribution across leaf surfaces for better efficacy.

Paper and leather manufacturers incorporate it into processing baths to assist with degreasing hides and controlling pitch deposits during pulping and manufacturing stages.

Supplied as a clear to slightly hazy liquid, it is available across a range of ethoxylation degrees that determine HLB value and specific application fit for various industries.

Standard commercial grades include technical-grade material, with ethoxylate chain lengths typically ranging from 4 to 40 moles of ethylene oxide. Drum and IBC bulk packaging are standard.
