    Sorbitan Monostearate (Span 60)CAS 1338‑41‑6

    Sorbitan Monostearate, commonly known as Span 60, is a nonionic surfactant derived from sorbitol and stearic acid. Identified by CAS No. 1338‑41‑6, it functions primarily as a water‑in‑oil (W/O) emulsifier with excellent stability in non‑aqueous systems. Span 60 is widely used in food, pharmaceutical, cosmetic, and industrial formulations where low HLB emulsification and thermal stability are required. The product is supplied with standard documentation including MSDS, TDS, and COA.

    AppearanceWhite to pale yellow waxy solid or flakes, with a slight fatty odor
    Density0.98-1.03 g/cm³ (at 25°C)
    Melting Point51-57°C (lit.)
    Boiling Point579.0±45.0°C (at 760 mmHg)
    Flash Point>110°C (some sources indicate >185°C)
    Solubility– Insoluble in cold water, dispersible in hot water to form a milky emulsion
    – Soluble in hot ethanol, benzene, mineral oil, vegetable oil, and other organic solvents
    – Slightly soluble in ethyl ether and petroleum ether
    HLB Value4.7 (indicating strong oil-solubility, suitable for W/O emulsions)
    StabilityStable under recommended storage conditions, avoid contact with strong oxidizing agents

    Application Areas

    Emulsifier: As a nonionic emulsifier, it is widely used in the preparation of oil-in-water (O/W) emulsions, such as in cosmetics (face cream, lotion), food (butter, ice cream), and pharmaceuticals (ointment, cream), etc.
    Wetting agents and dispersants: used in textile, paint, petroleum, and other industries to enhance wettability and dispersibility.
    Other purposes:
    Used as a crystal modifier in artificial cream to reduce the “gritty” feeling.
    Prevent gum sticking and enhance flexibility in chewing gum.

    Storage conditions

    Store in a cool, dry, well-ventilated warehouse, away from sources of fire and heat.
    Keep sealed to prevent moisture absorption and contamination. The shelf life is usually 2 years.

    ‌‌Safety precautions

    Safety: Non-toxic, meets food-grade standards (such as FCC grade), but avoid inhaling dust or contacting eyes

    Environmental protection requirements: Discarded packaging must be disposed of in accordance with chemical regulations to avoid polluting water bodies or soil. It is recommended to adopt a closed-loop system during the production process to reduce emissions
