    Product Overview

    Polysorbate 80 is provided as a nonionic emulsifier and solubilizer for formulated systems requiring stable dispersion between oil and water phases. This material is commonly selected for formulations where interfacial stabilization, wetting performance, and ingredient compatibility are important.

    Depending on the required grade, it may be applied in personal care products, pharmaceutical preparations, food-related systems, textile processing, and other industrial formulations. Product selection should be based on the intended application, compliance requirements, and formulation design.

    FAQ - Technical & Supply Chain

    • Q:

      What type of surfactant is Tween-80 (Polysorbate 80) and what is its function in formulations?

      A: Tween-80 (Polysorbate 80) CAS 9005-65-6 is a nonionic polysorbate surfactant derived from sorbitan monooleate ethoxylation. It functions as an emulsifier, solubilizer, wetting agent, and dispersing aid in multiphase systems including oil-in-water emulsions and aqueous formulations across personal care, pharmaceutical, textile, and industrial applications.
    • Q:

      What is the difference between Tween-80 and Span 80, and when should each be used?

      A: Tween-80 (Polysorbate 80) is water-soluble with an HLB value of approximately 15, making it suitable for oil-in-water emulsification, while Span 80 (Sorbitan Monooleate) is oil-soluble with a low HLB of approximately 4.3 for water-in-oil systems. These two surfactants are often combined to achieve the desired HLB balance for stable emulsion systems.
    • Q:

      Is Tween-80 CAS 9005-65-6 suitable for personal care and cosmetic formulations?

      A: Yes, Polysorbate 80 is widely used in personal care and cosmetic systems where stable emulsification, ingredient solubilization, and wetting performance are required. It is applicable in creams, lotions, serums, cleansers, and fragrance solubilization.
    • Q:

      What key specifications should be verified before ordering Polysorbate 80?

      A: The critical specification is the active content (99% grade supplied). Buyers should also confirm the saponification value, hydroxyl value, and acid value. Packaging options include 200 kg iron drums and 50 kg plastic drums. COA and TDS can be provided upon request.
    • Q:

      Can Tween-80 be used in pharmaceutical or food-contact applications?

      A: Tween-80 CAS 9005-65-6 may be used in pharmaceutical and food-related systems when the supplied grade meets the relevant regulatory requirements. The buyer is responsible for verifying suitability for their specific regulatory framework and target market.
