    Product Description

    Hyaluronic Acid, CAS 9067-32-7, also known as Sodium Hyaluronate or hyaluronan sodium salt, is a high-purity, fermentation-based glycosaminoglycan biopolymer; the EC/EINECS number is 232-678-0.

    Synonyms: Sodium Hyaluronate; HA; Hyaluronan; Sodium Hyalurate.

    CAS: 9067-32-7.

    Molecular formula: (C₁₄H₂₀NNaO₁₁)ₙ.

    Molecular weight: polymer, typically about 10 kDa to 3,000 kDa, grade-dependent.

    EC number: 232-678-0.

    It is a white to off-white, free-flowing, odorless powder, freely soluble in water to give a clear to slightly opalescent solution.

    A 1% aqueous solution at 25 °C typically has a pH of 5.5–7.5; the assay on the dried basis is typically ≥95.0%.

    Typical controls include loss on drying ≤10.0%, protein ≤0.03–0.04%, nucleic acids (A260) ≤0.5, heavy metals ≤20 ppm and TAMC <100 CFU/g.

    It is used as a humectant and moisturizing active in serums, creams, lotions, masks, toners, essences, ampoules and hair-care products.

    It acts mainly by binding and retaining water, forming a breathable film and improving skin elasticity, smoothness and long-lasting hydration.

    It is also used in ophthalmic solutions, eye drops, intraocular viscoelastic agents, intra-articular injections, wound dressings and tissue-engineering scaffolds.

    Low-molecular-weight or oligo grades are selected for better penetration and bioactive delivery; high-molecular-weight grades give stronger film-forming, hydration and lubrication.

    Confirm the molecular-weight range, assay, appearance, pH, loss on drying, protein and heavy-metal limits, intrinsic or solution viscosity and microbial limits; the grade must match the intended cosmetic, pharmaceutical or dietary use.

    Confirm the current product-specific specification.

    Confirm packaging with the requested quantity and destination requirements.

    Document requirements should be confirmed from the current specification, SDS, COA or other product-specific files.

    FAQ - Technical & Supply Chain

    • Q:

      Does Hyaluronic Acid CAS 9067-32-7 refer to the acid or the sodium salt?

      A: CAS 9067-32-7 identifies Sodium Hyaluronate, the water-soluble sodium salt form of hyaluronic acid. Industrially supplied cosmetic and pharmaceutical powders are normally this stable salt form.
    • Q:

      Which molecular-weight range should I select for Hyaluronic Acid powder?

      A: Choose low-molecular-weight or oligo grades for better penetration and bioactive delivery, and high-molecular-weight grades for stronger film-forming, hydration and lubricating effects. For skin-care formulations, a combination or a mid-range molecular weight is often used.
    • Q:

      How does molecular weight change the behavior of Sodium Hyaluronate in formulations?

      A: High-molecular-weight Sodium Hyaluronate contributes viscosity, barrier protection and long-lasting surface moisture, while lower-molecular-weight material is easier to dissolve and can penetrate more readily. The ideal choice depends on the serum, cream, eye-drop or injection application.
    • Q:

      Is this Hyaluronic Acid powder animal-derived or fermentation-based?

      A: This product is fermentation-based Sodium Hyaluronate, not an animal-derived extract. Bio-fermentation production provides better consistency, lower endotoxin risk and suitability for high-purity cosmetic, pharmaceutical and medical applications.
    • Q:

      What key specifications should be checked for Hyaluronic Acid CAS 9067-32-7?

      A: Confirm molecular-weight range, assay, appearance, pH, loss on drying, protein and heavy-metal limits, intrinsic or solution viscosity, and microbial limits. The grade should match the intended cosmetic, pharmaceutical or dietary use.
    • Q:

      How should Sodium Hyaluronate powder be stored and handled?

      A: Keep it in tightly closed, moisture-protected containers in a cool, dry environment away from strong temperature changes and direct sunlight. Use dust-control measures and appropriate PPE during weighing and transfer.
