Application

(Hydroxypropyl)methyl cellulose (HPMC), an inert viscoelastic polymer is used as an emulsifier, thickening and suspending agent similar to animal gelatin. HPMC is used in the development of controlled-delivery medicament.
Thickener for aqueous and non-aqueous systems, clear films with grease resistance, binders, lubricants, steric stabilizer and water retention aid.

Features and Benefits

Dissolves in water, undergoes reversible gelation upon heating, non-ionic, does not complex with ionic species and is surface active and enzyme resistant. Solutions are pseudoplastic.

Preguntas

1–3 de 3 Preguntas  
  1. What is the molecular weight (Mw) of Sigma-Aldrich product 09963 (hydroxypropyl methylcellulose, HPMC), and is this value specified or only estimated based on viscosity grade?

    1 respuesta
    1. Molecular weight is not tested for this polymer. The product is characterized by its viscosity (15 mPa·s, 2% in water at 25°C) and substitution level rather than a defined Mw.

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

    1 respuesta
    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

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

    1 respuesta
    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
