Application

Xanthan gum is an anionic polysaccharide composed of a β-(1→4)-D-glucopyranose glucan backbone with side chains of (1→3)-α-D-mannopyranose-(2→1)-β-D-glucuronic acid-(4→1)-β-D-mannopyranose on alternating residues. Approximately half of the terminal mannose residues are 4,6-pyruvated while most of the inner mannose residues are 6-acetylated. Its properties make it a useful matrix component for drug delivery systems. It forms stable drug suspensions in aqueous media and soft gels with locust bean gum or guar gum.

Its properties make it a useful matrix component for drug delivery systems. It forms stable drug suspensions in aqueous media and soft gels with locust bean gum or guar gum. Xanthan gum mimics the texture of lipids and is used as a control in experiments where signaling pathways initiated by consumption of lipid-containing reagents are investigated in mice.

Other Notes

A polysaccharide containing glucose, mannose, potassium glucuronate, acetate and pyruvate. Forms a hydrophilic colloid.

Questions

1–10 of 12 Questions  

  1. which sterilization technique would you recommend for xanthan gum?

    1 answer

    1. Sterilization studies have not been performed on this product. Historical data indicates that UV irradiation has been effective. In addition, literature suggest that autoclaving xanthan gum solutions containing 0.15M NaCl at 121°C for 30 minutes is effective, with no loss in structural integrity or viscosity.

  2. What is an exact percentage of pyruvated and acetylated groups of the Xanthan Gum from Xanthomonas campestris (G1253-100G, CAS: 11138-66-2)? (It's needed for a Scientific Journal)

    1 answer

    1. The exact percentage of pyruvated and acetylated groups in Xanthan Gum has not been tested.

      Helpful?

  3. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

  7. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
