Question

What is Tristyrylphenol Polyoxyethylene Ether 600-1? What are its main applications?

Answer

Tristyrylphenol Polyoxyethylene Ether 600-1 is a high-performance nonionic surfactant widely used in pesticide emulsification, coating dispersion, textile printing and dyeing, and industrial cleaning.

Detailed Description

Tristyrylphenol Polyoxyethylene Ether 600-1 (CAS: 99734-09-5), also known as Agricultural Emulsifier 600#-1, Emulsifier 600#-1, or Polyoxyethylene Tristyrylphenyl Ether, is a high-performance nonionic surfactant produced by Haian Guoli Chemical Co., Ltd. The product appears as a light yellow to brownish-yellow viscous liquid or semi-solid. Due to its unique molecular structure design, it exhibits excellent emulsifying, dispersing, and wetting properties in various demanding formulation systems.

The core advantage of this product lies in its superior interfacial activity—it effectively reduces interfacial tension and shows excellent compatibility with organophosphorus and organochlorine pesticides; it also possesses outstanding chemical stability, remaining active under acidic, alkaline, and hard water conditions, with strong compatibility and resistance to hydrolysis. Additionally, the product has low-foaming and high-efficiency characteristics, making it suitable for applications requiring strict foam control, such as circulating cleaning and spraying.

In terms of safety, this product is classified as non-hazardous, with low toxicity (rat oral LD50 >5000 mg/kg), non-irritating to skin, slightly irritating to eyes, and readily biodegradable (biodegradation rate >60% in 28 days), making it an environmentally friendly product that is easy to transport, store, and use.

Main Applications

1. Pesticide Formulation Processing

As a highly efficient nonionic emulsifier monomer in pesticide emulsifiable concentrate (EC) formulations, it is widely used in organophosphorus, organochlorine, and their compound EC products, ensuring dilution stability and efficacy of the spray solution. It is one of the core products in the Agricultural Emulsifier 600# series.

2. Coatings and Inks Industry

Used as an effective pigment wetting dispersant, it prevents filler flocculation and settling, improves the dispersion effect of pigments and fillers, effectively prevents floating color and flooding, and significantly enhances coating gloss and color saturation.

3. Textile Printing and Dyeing Industry

Used as a leveling agent and dispersant, it promotes uniform dye penetration, effectively prevents dyeing defects such as color spots and streaks, and improves dyeing quality and fabric hand feel.

4. Industrial Cleaning Field

Suitable for low-foaming cleaning formulations, it provides strong penetration and emulsifying detergency in metalworking fluids and hard surface cleaners while effectively controlling foam generation, making it suitable for circulating cleaning and high-pressure spraying applications.

Application Recommendations

In pesticide emulsifiable concentrate formulations, it is recommended to use in combination with other emulsifiers based on the type of active ingredient (organophosphorus, organochlorine, etc.) to achieve optimal emulsification; in coating systems, it is recommended to add during the grinding stage to fully utilize its wetting and dispersing effects; in industrial cleaning formulations, it can be used alone or combined with other surfactants to obtain low-foaming and high-efficiency cleaning performance.

Precautions

  • The product should be stored sealed in a cool, dry, and well-ventilated place, avoiding high temperature, moisture, and direct sunlight.
  • Keep away from strong oxidizers and strong acids to prevent unintended reactions.
  • It is recommended to wear conventional protective gloves and safety glasses during operation, and keep the working area well ventilated.
  • Tighten the container cap promptly after use to prevent moisture absorption or contamination.
