    Laureth‑4Ethoxylated Lauryl Alcohol CAS 68439‑50‑9

    Laureth-4, chemically identified as the polyethylene glycol ether of lauryl alcohol with an average of four ethylene oxide units, is a versatile non-ionic surfactant with a low-to-intermediate hydrophilic-lipophilic balance (HLB). Often designated in technical formulations as Polyoxyethylene lauryl ether or Ethoxylated dodecanol, this liquid compound functions as an excellent water-in-oil emulsifier, a solubilizer for oils, and a wetting agent in industrial cleaning concentrates and textile processing. We offer bulk supply of this high-purity surfactant with competitive factory pricing, customized specifications for hydroxyl value and pH, and comprehensive regulatory documentation including MSDS, TDS, COA.

    Physicochemical properties

    PropertyDescription
    AppearanceLight yellow transparent liquid
    Solubility– Easily soluble in oil and polar solvents (e.g., ethanol, toluene).
    – Dispersible in water to form emulsions.
    Stability– Stable under 0℃ (no layering or precipitation).
    – Resistant to acids, bases, and oxidizers.
    Hydrophobic-Lipophilic Balance (HLB)8-10 (oil-in-water emulsifier range)
    ViscosityLow viscosity at room temperature
    Cloud PointNot explicitly defined, but low-temperature stability suggests <0℃
    pH (1% aqueous solution)Neutral (pH 6-7)
    DensityApproximately 0.98-1.02 g/cm³ (at 20℃)

    Application Areas

    Personal care: Emulsifier, solubilizer in cosmetics.
    Low-foam systems: Suitable for processes requiring foam inhibition

    Industrial cleaning: Decontaminant, degreaser.
    Textile: Detergent, leveling agent.
    Petroleum: Emulsifier for mineral oils.

    Storage conditions

    Temperature: MOA-3B should be stored in a cool, dry, and ventilated warehouse, avoiding direct sunlight and high temperature environments. The storage temperature in winter should not be lower than 5 ℃ -15 ℃ to prevent delamination or deterioration caused by excessive temperature difference.
    Humidity: Keep the storage environment dry to prevent the product from absorbing moisture, clumping, or degrading.
    Shelf life management:
    The shelf life of MOA-3B is usually 2 years, and it should be used up within the shelf life.
    Products that have exceeded their shelf life should undergo quality testing and be confirmed to be qualified before they can continue to be used

    ‌‌Safety precautions

    Non-ionic surfactant, generally low toxicity.
    Wear protective gloves/goggles during handling.
    Dispose of waste according to local regulations.

    FAQ - Technical & Supply Chain

    • Q:

      Why does Laureth‑4 share the same CAS as other AEO products?

      A: CAS 68439‑50‑9 represents a UVCB category for lauryl alcohol ethoxylates with varying EO numbers, not a single fixed molecule.
    • Q:

      Is Laureth‑4 suitable for cosmetic use?

      A: Yes, when produced to appropriate specifications and purity standards, Laureth‑4 is widely used in personal care formulations.
