Tristyrylphenol Ethoxylate 600-1 is a high-performance nonionic surfactant widely used as a core component in pesticide emulsifiers, paint dispersants, textile auxiliaries, and industrial cleaners.
Detailed Description
Tristyrylphenol Ethoxylate 600-1 (CAS No.: 99734-09-5) is a general-purpose nonionic surfactant produced by Guoli Chemical, appearing as a light yellow to brownish yellow viscous liquid or semi-solid. Its molecular structure features tristyrylphenol as the hydrophobic group linked to a polyoxyethylene ether hydrophilic chain. This unique amphiphilic structure endows the product with excellent interfacial activity. It can effectively reduce oil/water interfacial tension at minimal dosage, demonstrating outstanding compatibility and emulsification stability with pesticide systems such as organophosphorus and organochlorine compounds.
As a classic nonionic additive, it exhibits stable chemical performance over a wide pH range and in hard water conditions, is resistant to hydrolysis, and offers strong compatibility. It also possesses low-foam efficiency and excellent wetting and spreading properties, making it ideal for cyclic spraying and industrial cleaning scenarios where foam control is critical. The active ingredient content is no less than 99%, with an HLB value of approximately 6, providing natural advantages for use in oil-soluble systems and emulsifiable concentrate formulations.

Application Recommendations
Based on the application experience of Guoli Chemical, this product excels in four major areas:
- Pesticide Formulation Processing: As a core emulsifier monomer for organophosphorus, organochlorine, and their compounded emulsifiable concentrate formulations, it ensures spontaneous emulsification upon dilution, forming a long-term stable emulsion and effectively enhancing efficacy. It is recommended to be used in combination with other nonionic or anionic emulsifiers to achieve optimal hydrophilic-lipophilic balance.
- Coatings and Inks: Used as a highly effective pigment wetting and dispersing agent, it strongly adsorbs onto pigment particle surfaces, preventing filler flocculation and sedimentation, thereby significantly improving coating gloss, color saturation, and storage stability.
- Textile Dyeing and Printing: As a leveling agent and dispersant, it promotes uniform dye penetration into fibers, effectively reducing color spots, streaks, and other dyeing defects, while also improving fabric hand feel.
- Industrial Cleaning: As a low-foam surfactant component, it is ideal for metalworking fluids, high-pressure spray cleaning, and hard surface cleaning formulations, providing strong penetration and detergency while effectively controlling foam to avoid overflow risks.
Precautions
- Safe Handling: This product is low-toxicity, non-irritating, and non-hazardous. However, it is still recommended to wear gloves and safety glasses during operation to avoid prolonged direct contact. In case of eye contact, rinse with plenty of water for at least 15 minutes and seek medical attention.
- Storage Recommendations: Store in a sealed container in a cool, dry, and well-ventilated place, away from direct sunlight, strong oxidizing agents, and strong acids. The product may have a low pour point and may solidify or become turbid at low temperatures; this is a normal physical phenomenon. Warm to room temperature and stir evenly before use.
- Packaging Specifications: Guoli Chemical offers packaging in 50 kg plastic drums, 200 kg plastic drums, and IBC totes. Please select the appropriate specification according to your needs.
