    Typical Supply Form Viscous substance or liquid depending on temperature and concentration
    Typical Active Content ≥68%; some supplied grades may be around 70%
    Physical & Chemical Properties
    Appearance Colorless to pale yellow viscous substance or liquid
    pH (1% aqueous solution) 6–8
    Solubility Easily soluble in water and common organic solvents
    Handling Behavior High viscosity at room temperature; dissolves more rapidly when heated to around 40°C
    Penetration Performance ≤8 seconds under the stated alkaline test conditions on the source page
    Alkali Resistance Withstands 200 g/L NaOH; some source-page statements mention up to 250 g/L depending on grade

    Stability Reported as chemically stable and compatible with hard water; source page also states resistance to concentrated alkalis and some oxidizing or reducing conditions
    Applications
    • Used in textile printing and dyeing as an alkali-resistant refining agent and penetrant to improve wetting and bath penetration.
    • Suitable for textile pretreatment systems operating under strongly alkaline conditions.
    • Applied in electroplating and electronics-related process formulations where surface wetting support is required.
    • Used in metal surface treatment for cleaning, degreasing and pretreatment support.
    • Can be compounded into detergents, leveling agents, emulsifiers and penetrants for industrial process systems.
    • Suitable for related industrial formulations requiring nonionic surface activity and alkali-resistant penetration performance.
    Packaging
    • 50 kg plastic drum

    Packaging information may vary according to supplied concentration and shipment arrangement.

    Storage Conditions
    • Store in a cool and dry place away from direct sunlight.
    • Keep in sealed containers to reduce moisture and impurity entry.
    • Room-temperature storage is recommended.
    • Avoid prolonged exposure to excessively high or low storage temperatures.
    Safety Precautions
    • Wear chemical-resistant gloves, protective work clothing and eye or face protection during handling.
    • Use suitable respiratory protection when required by the operating environment or emergency conditions.
    • Because the product can be highly viscous, warming to around 40°C may be used to assist dissolution where process conditions allow.
    • Avoid direct contact with high heat and open flame during handling.
    • Avoid contact with incompatible strong oxidants.
    • Refer to the current SDS for detailed handling, disposal and first-aid information.
