Tristyrylphenol Polyoxyethylene Ether 600-2 (manufactured by Guoli Chemical, CAS: 99734-09-5) is a light yellow viscous liquid to waxy solid at room temperature, easily soluble in water and polar solvents such as alcohols and ketones. This characteristic determines its flexible feeding method. Generally, it is recommended to first mix it uniformly with the oil phase, then slowly add it to water under stirring for emulsification; or directly dissolve it in the aqueous phase. The specific sequence depends on the formulation process. If the product solidifies or becomes viscous due to low temperature, simply warm it appropriately at room temperature and stir evenly to restore fluidity and original quality, without affecting the use effect.
The core function of this product originates from its unique polyphenyl anchoring group and polyoxyethylene chain segment. Its hydrophilic-lipophilic balance (HLB) value is approximately 11.5, and the cloud point is 50~60°C, making it especially suitable for stabilizing oil-in-water (O/W) systems. In practical use, it is often combined with anionic surfactants (such as calcium salts) to produce a synergistic effect and construct a more dense and stable interfacial film. It is recommended to determine the optimal compounding ratio and total addition amount through small-scale experiments.
According to the Guoli Chemical product database, the effective content of this product is ≥99%, water content ≤1.0%, and it has extremely high chemical stability, being resistant to acids, alkalis, hard water, and various electrolytes, allowing it to remain active in complex industrial formulations. Basic industrial hygiene practices should be followed during operation, such as wearing gloves and goggles.

1. Pesticide Emulsifier: When used in preparing emulsifiable concentrates (EC), oil-in-water emulsions (EW), and microemulsions (ME), the recommended dosage is generally 3%~10% of the total formulation. When compounded with anionic emulsifiers such as calcium dodecylbenzene sulfonate, it can significantly improve emulsion stability and the penetration and spreading ability of the spray liquid on leaf surfaces. Operation: first mix this product with the pesticide technical and solvent to form a uniform oil phase, then pour it into the aqueous phase under high-speed stirring.
2. Polymer Emulsion Polymerization: In emulsion polymerization of acrylates, styrene-acrylic, etc., as a primary or auxiliary emulsifier, the dosage is generally 1%~4% of the total monomer amount. It provides excellent mechanical and chemical stability and effectively controls the particle size of latex particles. It is recommended to add it to the water phase during the pre-emulsification stage and stir to dissolve, then mix with monomers for emulsification.
3. Textile Dyeing and Printing Auxiliaries: As a leveling agent and dispersant component, the recommended dosage is 1~5 g/L. It can effectively disperse dyes and prevent color spots. Add directly to the dye bath and circulate uniformly at room temperature or 40~50°C to take effect.
4. Industrial Cleaners: For metal or hard surface cleaning formulations, the recommended addition amount is 2%~8%. With its strong degreasing and oil-removing ability and acid-base resistance, it works better when combined with alkaline auxiliaries or solvents. Its low-foaming characteristic is suitable for industrial spray cleaning, easy to rinse without residue.
