    Cetostearyl Alcohol CAS 67762-27-0

    Cetostearyl Alcohol (CAS 67762-27-0), widely recognized in the industry as Cetearyl Alcohol, is a versatile fatty alcohol mixture utilizing its amphiphilic structure to function as a universal emulsion stabilizer and viscosity builder in cosmetic formulations. Chemically identified as a mixture of Cetyl alcohol (C16) and Stearyl alcohol (C18), this white waxy solid functions to form lamellar gel networks in oil-in-water emulsions, significantly enhancing the texture, stability, and carrying capacity of creams and lotions. As a vegetable-derived Fatty alcohol (typically from palm or coconut oil), it is extensively integrated into hair conditioners, face creams, and depilatories to provide a velvety skin feel and opacity without the greasy residue of waxes. We ensure bulk supply capabilities for this material, providing access to competitive factory pricing and customized specifications to meet specific C16/C18 ratios (e.g., 30/70, 50/50, or 70/30). Full technical documentation, including MSDS, TDS, COA, is available to support compliance and safety protocols.

    Product Description

    Cetostearyl Alcohol is a non-ionic surfactant produced from the hydrogenation of vegetable oils (Palm Oil or Coconut Oil). Unlike liquid ethanol, this is a “fatty” alcohol, meaning it moisturizes and conditions rather than dries the skin.

    Core Functions:

    1. Viscosity Builder: It creates the creamy structure in lotions and creams.
    2. Emulsion Stabilizer: It strengthens the interface between oil and water, preventing separation.
    3. Opacifier: It gives clear formulations a luxurious, opaque white appearance.
    4. Emollient: It leaves a soft, non-greasy film on the skin and hair.

    Physicochemical Properties

    The data below represents the most common commercial specification (Type 30/70, widely used for high viscosity creams).

    ParameterSpecification (Standard)
    AppearanceWhite flakes, pellets, or pastilles
    OdorMild, characteristic waxy odor
    Acid Value≤ 0.5 mg KOH/g
    Iodine Value≤ 0.5 g I2/100g
    Saponification Value≤ 1.0 mg KOH/g
    Hydroxyl Value205 – 225 mg KOH/g
    Melting Point48°C – 54°C
    Water Content≤ 0.3%
    C16 (Cetyl Alcohol) Content22% – 32% (or customized 50/50)
    C18 (Stearyl Alcohol) Content66% – 76% (or customized 50/50)
    Color (APHA/Hazen)≤ 10 (Melting state)

    Applications

    1. Skin Care (Creams & Lotions):
      • Used as the primary thickener and bodying agent. It determines the “stiffness” of the cream.
    2. Hair Care (Conditioners & Masks):
      • Provides slip and detangling properties. It is the base of almost all hair conditioners combined with cationic surfactants.
    3. Surfactant Manufacturing:
      • Used as a raw material to produce ethoxylated emulsifiers (e.g., Ceteareth-20, Ceteareth-25).
    4. Pharmaceuticals:
      • Used as an emulsifying wax base in medicated ointments and creams.

    Storage Conditions

    • Temperature: Store in a cool, dry area, preferably below 40°C. Avoid high temperatures as the product may fuse or melt (melting point is ~50°C).
    • Ventilation: Keep the storage area well-ventilated.
    • Stacking: Do not stack pallets too high to prevent pressure caking of the bottom bags.
    • Shelf Life: 24 months in original unopened packaging.

    Safety Precautions

    • Handling: Generally non-toxic and non-irritating to the skin in its raw form.
    • Eye Contact: May cause mild mechanical irritation. Flush with water if particles enter eyes.
    • Flammability: Combustible solid. Keep away from open flames and strong oxidizing agents.
    • Environmental: Biodegradable. Do not discharge into drains in large quantities due to potential clogging (solidifies when cool).

    FAQ - Technical & Supply Chain

    • Q:

      Chemically, how does the C16/C18 ratio affect the performance of Cetostearyl Alcohol CAS 67762-27-0?

      A: The ratio determines the melting point and viscosity building potential; a higher Stearyl (C18) content (e.g., 30/70) generally results in a harder, more opaque product with higher viscosity, while a balanced ratio (50/50) offers a softer consistency and better spreadability.
    • Q:

      Is this ingredient considered an emulsifier?

      A: It is technically a "co-emulsifier." While it doesn't emulsify oils on its own effectively, it works synergistically with primary hydrophilic emulsifiers (like Ceteareth-20 or Glyceryl Stearate) to stabilize the emulsion interface and thicken the formulation.
