Question

What is tristyrylphenol polyoxyethylene ether 600-2, 600#-1

Answer

Tristyrylphenol polyoxyethylene ether 600-2 / 600-1 is a nonionic surfactant prepared by addition polymerization of ethylene oxide (EO) with tristyrylphenol as the hydrophobic group, CAS number 99734-09-5.

Product Overview

This product (also known as Tristyrylphenol ethoxylate, Polyoxyethylene tristyrylphenyl ether) belongs to the class of nonionic surfactants. The multi-phenyl ring structure in the molecule provides strong adsorption and anchoring capabilities. The core difference between 600-2 and 600-1 lies in the different number of ethylene oxide (EO) adducts, resulting in different hydrophilic-lipophilic balance (HLB) ranges, which can be used in combination to produce synergistic effects.

Core Properties

It exhibits excellent emulsifying and dispersing power, enabling rapid emulsification and long-term stability for challenging oil phase systems; outstanding tolerance to inorganic salts, acids, alkalis, and hard water; significantly reduces dynamic surface tension, promoting rapid spreading and penetration of liquids on solid surfaces or plant leaves; its waxy solid characteristics make it less prone to moisture absorption and caking in humid environments.

Precautions

This product is low toxicity but has irritant properties: Skin irritation (Category 2, H315), Serious eye irritation (Category 2, H319). Wear nitrile rubber gloves and chemical safety goggles during operation, and ensure good ventilation in the workplace. Low temperature solidification or increased viscosity is a normal physical phenomenon. Before use, warm to room temperature and stir evenly to restore fluidity, which does not affect the intrinsic quality.
