Tristyrylphenol ethoxylate 600-2 and 600-1 (CAS No.: 99734-09-5, also known as: Tristyrylphenol ethoxylate) are among the core products of Guoli Chemical. These products use tristyrylphenol as the hydrophobic group and are prepared via addition polymerization of ethylene oxide (EO). The multi-benzene ring structure in the molecule provides strong adsorption and anchoring capabilities. At room temperature, the product appears as a light yellow viscous liquid to waxy solid, easily soluble in water and common polar organic solvents such as methanol, ethanol, and acetone, and also exhibits good dispersibility in non-polar media like mineral oils.
600-2 and 600-1 provide different hydrophilic-lipophilic balance (HLB) ranges by adjusting the number of ethylene oxide adducts. When used in combination, they can form a denser and more stable interfacial film, producing significant synergistic effects. The product has stable chemical properties, resistant to acids, alkalis, hard water, and various metal salts. It is not prone to hydrolysis or oxidation degradation under normal storage and use conditions, ensuring the long-term storage safety of the final formulation.
The waxy solid characteristics of this product give it extremely low moisture sensitivity, making it less likely to absorb moisture and cake in humid environments, which facilitates storage, transportation, and production metering. Solidification or increased viscosity at low temperatures are normal physical phenomena. Before use, simply warm it appropriately at room temperature and stir evenly to restore fluidity, without affecting any intrinsic quality.
