Product Description
Tristyrylphenol Ethoxylate (TSP EO) CAS 99734-09-5, High Compatibility with Agrochemical Active Ingredients for Agricultural Production
Product Overview

Tristyrylphenol ethoxylates are non-ionic surfactants that appear as pale yellow to orange-yellow viscous pastes at room temperature. They have a pH of 5.0-7.0 in a 1% aqueous solution and are readily soluble in water, alcohols, aromatic hydrocarbons, and other solvents.

These surfactants exhibit resistance to weak acids, weak alkalis, and hard water, along with excellent compatibility and outstanding emulsifying, wetting, dispersing, and solubilizing capabilities.

Often formulated with anionic calcium salt emulsifiers, they are suitable for use with various pesticide emulsifiable concentrates including organophosphorus, organochlorine, and herbicide types, offering strong emulsion stability at low dosage levels. They also serve as high-temperature leveling agents in textile dyeing and printing, as well as industrial wetting and dispersing aids.
