600P-85% Tristyrylphenol Polyoxyethylene Ether Phosphate is an anionic surfactant with high active matter content (≥85%), appearing as a light yellow to yellow high-viscosity liquid. Based on the Guoli Chemical product database, this product has an HLB value of 12.5, is easily soluble in water and various organic solvents, and its 1% aqueous solution has a pH value between 2.0 and 3.5, showing acidity. Due to the presence of phosphate ester groups, it is prone to hydrolysis under strong alkaline conditions. Therefore, it is recommended to add it during the acid adjustment stage of formulation development or under neutral to slightly acidic conditions to ensure that the product activity is not affected.
This product has high viscosity (kinematic viscosity of 2000~5000 mm²/s at 25°C). In actual operation, it is recommended to use the following methods: if the formulation system allows, pre-dilute with a small amount of warm water or target solvent to reduce viscosity before feeding; after addition, stir thoroughly to ensure complete dispersion in the system. It is recommended to add slowly while stirring to avoid local concentration that may cause gelation or uneven dispersion.
Due to significant differences in formulation composition and performance requirements of different application systems, Guoli Chemical recommends that users determine the optimal addition ratio through gradient tests and optimize the synergistic ratio with other additives to achieve the best emulsification, dispersion, or wetting effects.

The recommended usage methods and reference dosages of 600P-85% in various fields are as follows (data source: Guoli Chemical product database and industry common practices):
Suitable for formulations such as emulsifiable concentrate (EC), emulsion in water (EW), microemulsion (ME), suspension concentrate (SC), and oil-based suspension concentrate (OD). When preparing EC, premix this product with the oil phase, then add to the water phase under stirring; when preparing SC, it is recommended to add before milling to fully disperse the active ingredient particles. The reference dosage is 2%~8% of the total formulation, and the specific dosage should be determined through gradient tests based on the properties of the active ingredient and formulation requirements.
When used as a component of high-temperature leveling agents, it is recommended to add during the dye bath preparation stage, with a dosage of 0.5~3 g/L of the dye bath working solution. When used as a detergent, it can be compounded with other nonionic surfactants.
When preparing emulsified cutting fluids or wire drawing fluids, first mix this product evenly with base oil and oil phase components such as rust inhibitors, then slowly add to water to form a stable emulsion. The recommended dosage is 5%~15% of the total concentrate.
In hard surface cleaning formulations, it can be used in combination with penetrants, chelating agents, etc. The recommended dosage is 0.5%~3% of the working solution. Due to its low foaming characteristics, it is particularly suitable for high-pressure spray cleaning processes.
As a pigment wetting and dispersing agent, it is recommended to add during the grinding and dispersion stage, with a reference dosage of 1%~5% of the pigment mass. Premix with part of the water and co-solvent, then add to the pigment paste for joint grinding to achieve optimal dispersion and storage stability of the color paste.
As an emulsifier for emulsion polymerization of vinyl acetate, acrylates, etc., it can be added during the pre-emulsification stage, with a dosage of 1%~3% of the total monomer mass. This helps obtain a polymer emulsion with uniform particle size and good stability.
When used as an oil displacement agent or demulsifier component, the dosage should be adjusted based on downhole temperature, salinity, and other conditions. It is recommended to conduct laboratory evaluation tests to optimize the ratio before field application.
