Description générale

Hydroxypropyl cellulose (HPC) is a neutral polysaccharide prepared by reacting propylene oxide with alkali cellulose at high temperatures and pressure. It is soluble in water and many polar organic solvents. HPC is widely used as a food additive and in drug delivery systems.

Application

Hydroxypropyl cellulose can be used in the following applications:
  • HPC is soluble in organic solvents which makes it suitable for the preparation of polymer gel electrolytes for electrochemical devices. The network-forming ability of HPC can improve the mechanical and electrical properties of gel electrolytes.
  • Electrospun hydroxypropyl cellulose nanofibres can be used to develop drug delivery systems for a variety of hydrophobic drugs.
  • Hydroxypropylcellulose combined with an effervescent agent like sodium carbonate can be usedas a binder and functional material to prepare floating tablets for thecontrolled release of ofloxacin.

Questions

1–2 of 2 Questions  
  1. 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.

  2. 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
