    Product Description

    Sorbitan Trioleate (Span 85) CAS 26266-58-0 is a nonionic sorbitan ester with EINECS 247-569-3 and molecular formula C60H108O8.

    Synonyms: Sorbitan Trioleate; Span 85.

    CAS: 26266-58-0.

    Molecular formula: C60H108O8.

    It is commonly supplied as an amber to brown oily or viscous liquid.

    It has an HLB value commonly around 1.8, making it oil-soluble and suitable for water-in-oil emulsions.

    It is mainly used as an emulsifier, dispersion aid, and stabilizer in oil-based and water-in-oil systems.

    Typical applications include cosmetic and personal-care creams, gels and hair-care products, textiles, paints, and specialty industrial formulations.

    Its low HLB makes it a different formulation choice from high-HLB water-soluble emulsifiers.

    Confirm appearance, acid value, saponification value, hydroxyl value, moisture, and viscosity or color.

    Common ranges include an acid value of about 15 mg KOH/g maximum, saponification value of about 165-190 mg KOH/g, hydroxyl value of about 55-85 mg KOH/g, and moisture around 2% maximum.

    Confirm the required supply form and grade for the target formulation.

    Store in tightly closed containers in a cool, dry, well-ventilated area away from heat, ignition sources, and strong oxidizers.

    Use appropriate PPE and prevent spills or contamination.

    Confirm the offered package, net weight, and lot traceability before dispatch, and follow the current SDS.

    Every batch is checked for appearance, acid value, saponification value, hydroxyl value, moisture, viscosity, and color, with COA/TDS/SDS supplied per grade.

    Confirm acid value, saponification value, hydroxyl value, moisture, packaging, and grade as required.

    FAQ - Technical & Supply Chain

    • Q:

      What is Sorbitan Trioleate CAS 26266-58-0?

      A: Sorbitan Trioleate is a nonionic sorbitan ester with CAS 26266-58-0, EC 247-569-3, and molecular formula C60H108O8. It is also known as Span 85 and is commonly supplied as an amber to brown oily or viscous liquid.
    • Q:

      Why is Sorbitan Trioleate classified as a low-HLB emulsifier?

      A: It has an HLB value commonly around 1.8, meaning it is oil-soluble and more suitable for water-in-oil emulsions, oil-phase wetting, and co-emulsifier use in low-HLB systems. This makes it a different formulation choice from high-HLB water-soluble emulsifiers.
    • Q:

      Where is Sorbitan Trioleate mainly used?

      A: It is mainly used as an emulsifier, dispersion aid, and stabilizer in oil-based and water-in-oil systems. Typical applications include cosmetic and personal-care creams, gels and hair-care products, textiles, paints, and specialty industrial formulations.
    • Q:

      Which specifications should be checked before ordering Span 85?

      A: Confirm appearance, acid value, saponification value, hydroxyl value, moisture, and viscosity or color. Common ranges include an acid value of about 15 mg KOH/g maximum, saponification value of about 165-190 mg KOH/g, hydroxyl value of about 55-85 mg KOH/g, and moisture around 2% maximum.
    • Q:

      How should Sorbitan Trioleate be stored and handled?

      A: Store it in tightly closed containers in a cool, dry, well-ventilated area away from heat, ignition sources, and strong oxidizers. Use appropriate PPE and prevent spills or contamination, and confirm the offered package, net weight, and lot traceability before dispatch.
