    Tallow Amine Polyoxyethylene Ether TA-15 CAS 61791-26-2

    Tallow Amine Polyoxyethylene Ether TA-15, universally registered under CAS No. 61791-26-2, is a specialized surfactant produced by the ethoxylation of primary tallow amine with approximately 15 moles of ethylene oxide. This specific grade, often designated as PEG-15 Tallow Amine, acts as a versatile surface-active agent exhibiting both non-ionic and cationic properties depending on the pH of the system. With a relatively high hydrophilic-lipophilic balance (HLB), TA-15 offers excellent water solubility, emulsification, and wetting capabilities. It is most renowned in the chemical industry as a critical adjuvant for glyphosate-based herbicides, significantly enhancing weed-killing efficacy by improving leaf penetration. Beyond agrochemicals, it serves as a potent antistatic agent and dyeing auxiliary in the textile industry, and a corrosion inhibitor in metal processing fluids. We supply industrial-grade TA-15 with consistent amine values and low moisture content, available in bulk drums or IBCs.

    Application Areas

    Pesticide formulation: used as an emulsifier or wetting agent in emulsion formulations of herbicides such as glyphosate to enhance efficacy.
    Metalworking fluids: Prepare cutting and grinding fluids to provide lubrication and rust prevention properties, and extend tool life.
    Textile auxiliaries:     used as anti-static agents and leveling agents to improve fiber processing performance.
    Cosmetics and daily chemical products: High EO number models (such as EO>20) can be used for emulsification of cream products.
    Industrial cleaning: As a dispersant, it removes oil stains and heavy metal ions.

    Storage conditions

    Temperature: Below 40 ℃ to avoid product deterioration caused by high temperatures.
    Light exposure: Store in the dark to prevent direct sunlight.
    Isolation: Keep away from sources of fire, heat, and oxidants, and do not store mixed with acids.
    Shelf life: 24 months (stored under standard conditions).

    ‌‌Safety precautions

    Skin protection: Wear protective gloves and clothing during operation to avoid direct contact. ‌
    Respiratory protection: Operate in a well ventilated environment and wear respiratory protective equipment if necessary. ‌
    Leakage treatment: If a leak occurs, immediately cover and absorb it with sand or dry lime to avoid direct contact with the skin or inhalation of volatile substances. ‌
    Extinguishing method: use dry powder, carbon dioxide or foam extinguisher to extinguish the fire and avoid direct water spraying of leakage

    FAQ - Technical & Supply Chain

    • Q:

      What does the "TA-15" designation mean?

      A: "TA" stands for Tallow Amine, and "15" represents the average number of moles of Ethylene Oxide (EO) added to the amine molecule during synthesis. This degree of ethoxylation dictates the surfactant's solubility and HLB value.
    • Q:

      What is the primary use of CAS 61791-26-2 (TA-15)?

      A: Its largest volume application is as a surfactant adjuvant in agricultural herbicide formulations, particularly with glyphosate. It reduces surface tension on plant leaves and aids the uptake of the active ingredient. It is also widely used in textile dyeing and as an antistatic agent.
