    Octylphenol Ethoxylate (OP-10 / TX-100) – CAS 9036-19-5

    Octylphenol Ethoxylate (OP-10), chemically identified as a polyoxyethylene octyl phenyl ether with an average of ten ethylene oxide units, is a water-soluble non-ionic surfactant widely utilized for its excellent detergency and wetting properties. Often designated in technical specifications as Octoxynol-10, Polyethylene glycol octylphenyl ether, or Ethoxylated octylphenol, this viscous liquid functions as a key emulsifier in emulsion polymerization, a scouring agent in textile processing, and a dispersant in industrial cleaning formulations. We offer bulk supply of this industrial-grade surfactant with competitive factory pricing, customized specifications for specific cloud point requirements, and comprehensive technical documentation including MSDS, TDS, COA.

    Application Areas

    Textile industry: used as a leveling agent, diffusing agent, wetting agent, etc
    Pesticide industry: used as emulsifier, penetrant, etc
    Construction industry: used as emulsifiers for emulsified asphalt, concrete dispersants, etc
    Detergent industry: used as the main component of detergents to remove oil
    Metal surface technology industry: used as a carrier for tin plating brighteners, helping to dissolve the main brightener and improve cathodic polarization
    Polymer lotion polymerization: can be used as emulsifier

    Storage conditions

    Temperature: 5-30 ℃, avoid degradation caused by high temperature.
    Packaging: Sealed and stored in a dry and ventilated place to prevent moisture absorption and clumping.
    Shelf life: 2 years (according to the manufacturer’s standards).

    ‌‌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:

      Why do OP‑10 and TX‑100 share the same CAS number?

      A: CAS 9036‑19‑5 represents a UVCB category for octylphenol ethoxylates with varying EO numbers; OP‑10 and TX‑100 fall within this category.
    • Q:

      Are octylphenol ethoxylates restricted in some regions?

      A: Yes. Alkylphenol ethoxylates are subject to regulatory restrictions in certain regions, particularly in the EU, due to environmental concerns.
