Tristyrylphenol polyoxyethylene ether 600-1 (emulsifier 600#-1) is a nonionic surfactant with an HLB value of approximately 6, a cloud point of 45~55°C, easily soluble in oil, dispersible in water, and is a lipophilic emulsifier. Due to its varying functional roles in different application fields, there is no universally applicable dosage. The actual usage ratio needs to be determined through gradient experiments in combination with the target formulation system, the characteristics of the medium to be emulsified or dispersed, water hardness conditions, and production process conditions to find the optimal dosage.
From the product technical parameters, this product has an active content ≥99%, surface tension of about 35 mN/m, significant low-foaming characteristics, acid value ≤1, iodine value ≤1, and stable chemical properties. It can be stored for a long time at room temperature, but has limited tolerance under strong alkaline conditions. The acidity and alkalinity of formulation components need to be considered during formulation design.
The following are general reference ranges for typical application scenarios (data source: Guoli Chemical Product Database application field information combined with industry common practices; exact dosage needs to be verified through experiments):
| Application Field | Functional Role | Reference Dosage Range | Remarks |
|---|---|---|---|
| Pesticide emulsifiable concentrate formulation | Nonionic emulsifier monomer | Emulsifier total accounts for 5%~15% of the formulation; this product accounts for 20%~50% in the emulsifier blend | Often used in combination with anionic emulsifiers (e.g., agricultural emulsifier 500# series); specific ratio needs to be adjusted based on the polarity of the active ingredient |
| Coatings and inks | Pigment wetting and dispersing agent | 0.1%~1.0% of pigment weight | Recommended to add during pre-milling; combined with mechanical grinding can significantly improve dispersion efficiency |
| Textile dyeing and printing | Leveling agent/dispersing agent | Working bath solution 0.5~2.0 g/L | Adjust concentration based on dye type and dyeing process (e.g., exhaust dyeing, pad dyeing) |
| Industrial cleaning agents | Low-foaming penetrating and emulsifying component | 1%~5% of total formulation | Suitable for metal cleaning, hard surface cleaning, and other systems requiring foam control |
Formulation compatibility principles: This product has an HLB value of 6, making it a lipophilic emulsifier. When compounding in pesticide emulsifiable concentrates, it is recommended to use in combination with high-HLB nonionic or anionic emulsifiers to achieve a balanced oil-water phase. In coating dispersion applications, due to its low-foaming characteristics, it is particularly suitable for high-shear grinding processes, effectively avoiding dispersion efficiency reduction caused by foaming.
Addition method: This product is a light yellow to brownish yellow viscous liquid or paste at room temperature (freezing point ≤0°C). Under low-temperature environments, layering or solidification may occur. It is recommended to preheat and stir evenly in a 30~40°C water bath before use. Do not heat directly with an open flame. It is recommended to add slowly while stirring into the formulation system to ensure thorough mixing.
Water adaptability: This product maintains good interfacial activity under high-hardness water and acidic/alkaline conditions, and is not easily hydrolyzed or deactivated. However, attention should be paid to its limited tolerance to strong alkaline environments. When preparing alkaline cleaning agents, control the alkalinity or conduct compatibility pre-tests.
