일반 설명

Castor Oil, Ethoxylated is a nonionic solubilizer and emulsifier made by reacting castor oil with ethylene oxide. It is a pale yellow oily liquid that is clear at temperatures above 26°C. It has a faint but characteristic odour.
Castor Oil, Ethoxylated is polyethylene oxide surfactant and is viscous in nature. It has a hydrophobic-lipophilic balance value in the range of 12-14.[1]

애플리케이션

Castor Oil, Ethoxylated has been used as a detergent to improve the solubility of dye and to increase the transmembrane permeation.[2][3] It has been used as a vehicle for drug/stimulant delivery in cells.[4][5]

생화학적/생리학적 작용

Castor Oil, Ethoxylated is used in lipid-based formulations for drugs and solubilization of cosmetics.[1] Castor Oil, Ethoxylated is suitable for the production of semi-solid and liquid formulations of water-insoluble actives and other hydrophobic compounds.[1] Due to its emulsification functionality, it finds application in biological membrane- based drug transport studies.[6]

기타 정보

A derivative of castor oil and ethylene oxide.

질문

1–9 / 9 질문  

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

    1 답변

    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 답변

    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.
