    Agricultural Emulsifier 603 CAS 99734-09-5

    Agricultural Emulsifier 603, chemically identified as Tristyrylphenol Ethoxylate (TSPE) with a specific degree of ethoxylation, is a high-performance non-ionic surfactant essential for agrochemical formulations. Frequently referenced in technical data sheets as Polyoxyethylene tristyrylphenyl ether or Ethoxylated tristyrylphenol, this viscous liquid or semi-solid functions as a primary emulsifier in Emulsifiable Concentrates (EC), Suspension Concentrates (SC), and Microemulsions (EW) for pesticides and herbicides. We offer bulk supply of this specialized surfactant with competitive factory pricing, customized specifications for ethylene oxide (EO) mole content, and comprehensive regulatory documentation including MSDS, TDS, COA.

    ViscosityViscous liquid (varies with temperature and EO content)
    StabilityStable under normal conditions; resistant to hard water and electrolytes
    Storage ConditionsStore in a dry, ventilated place away from fire sources; avoid direct sunlight

    Application Areas

    Pesticide formulations are widely utilized in the preparation of emulsions for organophosphate insecticides (such as dichlorvos and phoxim), herbicides (such as glufosinate-ammonium), and fungicides.
    In other sectors, they can serve as leveling agents for high-temperature and high-pressure dyeing of disperse dyes, or as components in industrial cleaning agents and textile auxiliaries.

    Storage conditions


    Temperature: It is recommended to store in a cool, dry, well ventilated warehouse or canopy, avoiding high temperature environments (such as storage temperatures exceeding 35 ℃).
    Light exposure: Store in the dark to prevent direct sunlight from causing product deterioration.
    Isolation requirements: Keep away from sources of fire, heat, and oxidants, and do not store or transport with acids, edible chemical raw materials, etc.
    Shelf life: Under the above storage conditions, the shelf life is usually 1-2 years (subject to the data provided by the supplier).
    Regular inspection: During storage, it is necessary to regularly check the integrity of the packaging and the condition of the product. Any abnormalities found should be dealt with in a timely manner

    ‌‌Safety precautions

    Non hazardous chemicals, but protective gloves and goggles should be worn during operation to avoid contact with skin and eyes.
    Waste disposal must comply with local environmental regulations to prevent pollution of water bodies and soil.

    FAQ - Technical & Supply Chain

    • Q:

      What is the main application of Agricultural Emulsifier 603?

      A: It is primarily used in the formulation of chemical pesticides, specifically Emulsifiable Concentrates (EC). It helps dissolve the active pesticide ingredient in an organic solvent and ensures that when the farmer mixes the product with water, it forms a stable, milky white emulsion without phase separation.
    • Q:

      What kind of pesticides is CAS 99734-09-5 suitable for?

      A: Due to its unique polymeric structure, it is highly effective for emulsifying organophosphorus insecticides, organochlorines, and various herbicides that are difficult to stabilize with standard surfactants.
