Ethoxylated tristyrylphenol

Ethoxylated tristyrylphenol (CAS 70559-25-0), commercially known as Soprophor S 25, is a nonionic surfactant derived from a tristyrylphenol base with a polyethylene glycol chain. It delivers emulsification, wetting, and dispersion performance across demanding industrial formulations.

This chemical provides superior results where conventional alkylphenol ethoxylates fall short. In agrochemical formulations, it emulsifies concentrated pesticide and herbicide actives into stable emulsifiable concentrates and suspension concentrates.

Textile processors use it as a wetting and scouring agent to ensure uniform dye penetration and consistent fabric treatment. This ensures high-quality results during the manufacturing process for various textile materials.

In industrial and institutional cleaning formulations, it improves substrate wetting and helps disperse oils and soils from hard surfaces. This makes it a versatile component for heavy-duty cleaning applications and surface maintenance.

Coatings and adhesive manufacturers incorporate it to stabilize pigment dispersions and control surface tension in waterborne systems. This functionality is critical for maintaining the stability and performance of modern coating products.

Ethoxylated tristyrylphenol is typically supplied as a liquid or viscous paste, depending on the degree of ethoxylation. Standard supply grades include technical-grade material meeting industrial performance specifications.

Ethoxylation levels commonly range to suit HLB requirements across different formulation types. Packaging is available in drums and IBCs for bulk industrial procurement to meet the needs of large-scale manufacturing facilities.
