General description

Carnauba wax No.1 yellow(CW) is an ester based wax that can be extracted from palm leaves. The composition of this wax contains aliphatic esters, ω-hydroxy esters and unsaturated alcohols. It can be used as a glossing agent in a variety of pharmaceutical products.[1]

Application

CW may be used as a hydrophobic excipient which can be used to modify the kinetics of polymeric gel in a drug releasing system.[2] It can be used in dry polymeric coatings which can increase the crystallization and improve the stability of amorphous solid drug formulations.[3] It may also be used as a component of lipids which can be used to tune and improve the flowability and designing of solid drugs.[4]

Questions

1–4 of 4 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.
