Tristyrylphenol polyoxyethylene ether 600-2 and 600-1 are nonionic surfactants produced by Guoli Chemical, with CAS number 99734-09-5. These two products provide different hydrophilic-lipophilic balances by adjusting the number of ethylene oxide adducts (600-2 has an average EO number of 9-10, HLB value approximately 11.5). They can be used alone or in combination to achieve synergistic effects.
The specific addition amount depends on the application scenario, the properties of the oil phase to be emulsified, the water quality conditions of the system, and the compatibility of other components in the formulation. Currently, the product database of Guoli Chemical does not provide specific recommended addition amounts for each application field. The following reference dosage ranges are based on common industry practices; it is recommended to verify the optimal dosage through laboratory small-scale tests in actual use.
At room temperature, this product appears as a light yellow to brownish-yellow liquid or waxy solid (may solidify at low temperatures). If solidification occurs due to low temperature before use, simply warm it appropriately at room temperature and stir evenly to restore fluidity without affecting product quality. The product is easily soluble in water, alcohols, and ketone polar organic solvents. It can be diluted first with water or the solvent in the formulation before adding to the system to facilitate rapid and uniform dispersion.

Pesticide emulsifier (emulsifiable concentrate/oil-in-water emulsion/microemulsion): As a core component of nonionic emulsifiers, the recommended dosage is 3%~8% of the total formulation weight. It is often used in combination with anionic emulsifiers (such as calcium salts). Combining 600-2 and 600-1 can form a denser interfacial film, significantly improving the thermodynamic stability and dilution stability of the formulation.
Polymer emulsion polymerization emulsifier: In emulsion polymerization systems such as acrylates, styrene-acrylic, and vinyl acetate-acrylic, the recommended dosage is 1%~5% of the total monomer weight. It can be used alone or in combination with anionic emulsifiers to effectively control latex particle size and distribution, and improve the mechanical and chemical stability of the synthetic emulsion.
Textile printing and dyeing auxiliaries (leveling agent/dispersant/scouring aid): As a leveling agent component, the recommended dosage is 0.5~2 g/L of the dye bath. As a pretreatment wetting agent, the recommended dosage is 0.3%~1% of the working solution. It can effectively disperse dyes, prevent color spots, and improve leveling and dyeing fastness.
Industrial cleaning agents (metal cleaning/hard surface cleaning): In degreasing and decontamination formulations, the recommended dosage is 2%~10% of the cleaning concentrate. It is resistant to acids and bases, easy to rinse, suitable for room temperature and heated cleaning systems, and can quickly strip grease and organic dirt.
Papermaking and leather chemicals: As a deinking agent or dispersant component, the recommended dosage is 0.1%~0.5% of the working solution. In leather soaking, degreasing, and fatliquoring processes, the dosage is about 0.5%~1.5% of the leather weight, helping oil emulsification and penetration.
