General description

Polycaprolactone (PCL) is a semi crystalline hydrophobic biodegradable polyester which finds major applications as a drug delivery agent because of its cost efficiency, high toughness and biocompatibility. PCL possesses some unique properties such as:
  • It degrades slower than other biodegradable polyesters in physiological condition, this property can be exploited in the controlled release of drugs in target tissues over a period of time.
  • Its poor surface wetting and interaction with biological fluids on account of its hydrophobicity leads to poor cell adhesion and proliferation, hence it is blended with other synthetic /natural polymers.[1]

Application

  • PCL loaded with antibiotics may be used to treat infections of the respiratory tract, like tuberculosis.
  • Investigations were carried out based upon phenotypic responses of human bone marrow mesenchymal cells (hBMSCs) for different ratio of chitosan/ polycaprolactone (PCL) blends.[1]
  • PCL/biomedical ceramic materials have been studied for possible osteo tissue regeneration.
  • Action of PCL/graded insulin/beta-5 glycerophosphate concentrations on osteochondral tissue formation through adipose-derived stromal cell differentiation.[2]
  • Other general uses include:extrusion aid, die lubricant, mold release, pigment and filler dispersion aid and polyester segments in urethanes and block polyesters.

Questions

1–5 of 5 Questions  
  1. 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

  2. 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
