    Isotridecyl Alcohol Ethoxylate CAS 9043-30-5

    Isotridecyl Alcohol Ethoxylate, commercially designated as TO-7 or chemically known as Polyoxyethylene Isotridecyl Ether, is a nonionic surfactant synthesized from branched C13 isotridecanol. This substance functions as a rapid wetting agent and emulsifier, designed to effectively lower surface tension and solubilize oils in industrial wetting and degreasing formulations. It is typically applied in the production of heavy-duty hard surface cleaners, textile scouring agents, and leather processing auxiliaries where fast kinetics are required. We ensure bulk supply with competitive factory pricing for industrial clients. Our inventory is managed to support customized specifications, and every shipment is accompanied by complete MSDS, TDS, COA documentation.

    Storage conditions

    Storage environment:
    Keep out of direct sunlight: Avoid direct sunlight to prevent product deterioration caused by excessive temperature.
    Dryness: Keep the warehouse dry to prevent the product from absorbing moisture.
    Ventilation: Ensure good ventilation in the warehouse to avoid moisture or deterioration of products caused by poor air circulation.
    Storage conditions:
    Sealed storage: Store in a sealed container to prevent the product from coming into contact with air, thereby reducing the risks of oxidation and moisture absorption.
    Avoid high temperatures: The storage temperature should not exceed 60℃, as high temperatures may lead to product decomposition or performance degradation.
    Prevent static electricity: During storage and handling, anti-static measures should be taken to prevent the danger caused by static sparks.
    Storage period: Two years

    ‌‌Safety precautions

    Safety protection: Wear protective gloves, goggles, and dust masks to avoid direct skin contact or inhalation.
    Leakage treatment: Absorb with sand or inert materials and dispose of as hazardous waste.
    Disposal: Entrust qualified units to carry out harmless treatment, and prohibit arbitrary dumping.

    FAQ - Technical & Supply Chain

    • Q:

      Does the designation "TO-7" correspond to CAS 9043-30-5?

      A: Yes, CAS 9043-30-5 is the general registry number for Isotridecyl Alcohol Ethoxylates. The specific identifier "TO-7" indicates a grade with approximately 7 moles of ethylene oxide, which falls under this CAS classification and is commonly used for its specific hydrophilic-lipophilic balance (HLB).
    • Q:

      Is this material suitable for use in alkaline cleaning systems?

      A: Yes, this product is intended for use in a wide range of pH environments. It acts as a stable detergent component in industrial alkaline cleaners and degreasers, providing essential wetting and emulsification properties without rapid degradation.
