    Ceteareth-23 CAS 68439-49-6

    Ceteareth-23, chemically identified under the generic CAS number 68439-49-6 (Ethoxylated C16-18 Alcohols), is a high-performance non-ionic surfactant derived from natural cetearyl alcohol. Synthesized via the ethoxylation of a blend of cetyl and stearyl alcohols with an average of 23 moles of ethylene oxide, this compound is characterized by its high Hydrophilic-Lipophilic Balance (HLB) value (typically 15-17). This property makes Ceteareth-23 an exceptional oil-in-water (O/W) emulsifier and solubilizer, widely favored in the personal care and pharmaceutical industries. It appears as white waxy flakes or pellets and is valued for its ability to form stable, viscous emulsions and disperse oils in aqueous systems. It is highly compatible with a wide range of oils and active ingredients, ensuring stability in formulations ranging from heavy creams to lightweight lotions and hair conditioners. We supply Cosmetic Grade Ceteareth-23 in 25kg bags, fully compliant with industry standards.

    Physicochemical properties

    PropertyDescription
    Molecular WeightApproximately 1200-1500 g/mol (depending on EO chain length)
    AppearanceWhite to pale yellow waxy solid or paste
    SolubilitySoluble in water and organic solvents (e.g., ethanol, propylene glycol)
    HLB Value15-17 (hydrophilic-lipophilic balance, indicating strong emulsifying properties for O/W emulsions)
    Melting Point30-45°C (varies with EO content)
    Boiling PointNot applicable (decomposes before boiling)
    pH StabilityStable in a wide pH range (pH 3-10)
    Thermal StabilityResistant to high temperatures (suitable for high-temperature dyeing processes)
    ViscosityIncreases with concentration; forms gels at high levels in water
    Key Functions– Emulsifier: Stabilizes oil-in-water (O/W) emulsions.
    – Dispersant: Prevents aggregation of pigments or particles.
    – Thickening Agent: Enhances viscosity in formulations.
    – Wetting Agent: Reduces surface tension for better ingredient penetration.

    Application Areas

    – Cosmetics: Creams, lotions, shampoos, conditioners.
    – Pharmaceuticals: Ointments, topical creams.
    – Textile Industry: High-temperature dyeing (as a leveling agent).
    – Industrial Cleaning: Detergents, degreasers.

    Storage conditions

    Temperature: Store in a cool, dry, and well ventilated area, with a recommended temperature of 15-30 ° C. Avoid high temperatures (which may cause decomposition or oxidation) and freezing (which may affect stability).
    Container: Use sealed, corrosion-resistant containers (such as high-density polyethylene HDPE or stainless steel).
    Avoid light and moisture: Avoid direct sunlight and store in opaque containers. Keep dry and prevent moisture absorption and clumping (some polyethylene glycol ethers are prone to moisture absorption).
    Shelf life: usually 2 years (based on manufacturer data), after long-term storage, the properties (such as color and viscosity changes) need to be checked.

    ‌‌Safety precautions

    Personal Protection
    Skin contact: Wear chemical protective gloves (such as nitrile or chloroprene rubber) to avoid direct contact
    Operating environment: Ensure local ventilation and avoid high concentration exposure in enclosed spaces.
    Leakage handling
    Minor leakage: Cover with inert adsorbent materials (such as diatomaceous earth, sand), collect and dispose of as chemical waste.
    Massive leakage: Set up a cofferdam to prevent it from flowing into the sewer, and contact a professional handling team.
    fire risk
    Flammability: Flammable but not highly flammable, combustion may release toxic gases (such as carbon monoxide).
    Extinguishing agent: use foam, dry powder, carbon dioxide extinguisher or fog water to extinguish the fire.

    FAQ - Technical & Supply Chain

    • Q:

      What is the main function of Ceteareth-23 in cosmetic formulations?

      A: It functions primarily as an emulsifier for oil-in-water (O/W) systems. Due to its high HLB value, it helps disperse oil phases into water, creating stable creams and lotions. It also acts as a solubilizer for fragrances and active ingredients.
    • Q:

      How does Ceteareth-23 compare to Ceteareth-20 or Ceteareth-25?

      A: All three are very similar. The number denotes the moles of ethylene oxide. Ceteareth-23 has properties intermediate between 20 and 25. A higher number generally means higher water solubility and a higher HLB value. Ceteareth-23 forms slightly more rigid gels or emulsions compared to Ceteareth-20.
    • Q:

      What is the solubility of Ceteareth-23?

      A: It is soluble in water (giving a clear to hazy solution depending on concentration) and alcohol. It is insoluble in mineral oil and other non-polar solvents, though it can be dispersed in them at elevated temperatures.
