    Sorbitan Trioleate CAS 26266-58-0

    Sorbitan Trioleate is a nonionic surfactant and emulsifier commonly supplied for use in industrial, cosmetic, and related formulation systems. In supplier-side product positioning, it is better presented as a functional emulsifying ingredient rather than as a chemical intermediate or a general solvent. It is typically selected where oil-phase compatibility, emulsification support, and formulation stability are required. Standard export supply can be arranged with routine documents such as COA, TDS, and SDS according to customer requirements.

    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.
