Opis ogólny

Sodium alginate is the sodium salt of alginic acid, a polysaccharide found in brown algae.[1] It is generally used as a stabilizer and thickener in the food industry.[2]

Zastosowanie

Sodium alginate can be used to prepare:
  • Cationized casein-based polyelectrolyte complex for fragrance-controlled release applications.[3]
  • Aroma encapsulation or microcapsules for cosmetic applications.[4]

Inne uwagi

A straight-chain, hydrophilic, colloidal, polyuronic acid composed of guluronic and mannuronic acid residues.

Questions

1–10 of 18 Questions  

  1. How much sodium is present in product

    1 answer

    1. The sodium content has not been determined for this product.

      Helpful?

  2. I used to use a medium molecular weight sodium alginate (SA). Now, what if I use the SA with a lower or higher molecular weight? In this case, should I decrease/increase the amount of SA I use?

    1 answer

    1. A currently published frequently asked question on the product page notes, "The estimated molecular weight range for this material is 12,000 - 40,000 Daltons." Without knowing the "medium" molecular weight range previously used or the intended application, it is not possible to advise whether an adjustment in the amount of the product used is advisable.

  3. 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

  4. 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/449/386/product-dating-information-mk.pdf

  7. is it good for crosslinking with chloride calcium?(becuase of low viscosity)

    1 answer

    1. This product is a Flavors & Fragrance product typically used as a stabilizer and thickener in the food industry. The estimated molecular weight range for this material is 12,000 - 40,000 daltons. Currently, there is no product option available that has been tested for the ability to crosslink with calcium chloride. A brief search of the literature reveals a publication that used sodium alginate with a molecular weight of 100,000 daltons and an M/G ratio of 1.56 for calcium crosslinking studies. A link to this article, as well as potentially suitable products, has been listed below.

      A1112 : 60-70 % M 30-40 % G ; M/G ratio of 1.56. The degree of polymerization is 400-600. Molecular weight: approx. 30 000 - 100 000

  8. What is the density of Sodium Alginate, product W201502 (CAS 9005-38-3)?

    1 answer

    1. The density of the product is 1 g/mL.

      Helpful?

  9. Is there any information of the G/M ratio for this? what species of brown algae is this harvested from?

    1 answer

    1. The mannuronic to guluronic acid ratio for this product is not determined on a lot-specific basis. However, the typical mannuronic acid content is approximately 61% and the guluronic acid content is approximately 39%. with a resulting M/G ratio of 1.56. The species of brown algae is Macrocystis pyrifera.

  10. What is the sample size for Sodium alginate, Product W201502?

    1 answer

    1. The SAMPLE-K quantities vary from product to product and lot to lot. There is no established quantity assigned. These are typically gram quantities intended for use in formulation evaluation, however some more expensive compounds may contain smaller amounts.
