Application


  • Simultaneous electrochemical determination of three sunscreens using cetyltrimethylammonium bromide.: This study presents an electrochemical method for the simultaneous determination of sunscreens, including 2-Ethylhexyl 4-methoxycinnamate, using cetyltrimethylammonium bromide, highlighting the importance of analytical techniques in biochemistry (Cardoso et al., 2008).

  • Relationship between the ability of sunscreens containing 2-ethylhexyl-4′-methoxycinnamate to protect against UVR-induced inflammation, depletion of epidermal Langerhans (Ia+) cells and suppression of alloactivating capacity of murine skin in vivo.: This study evaluates the protective effects of sunscreens with 2-Ethylhexyl 4-methoxycinnamate against UV radiation-induced skin changes, contributing to the understanding of immune responses in dermatological biochemistry (Walker et al., 1994).

General description

OMC provides protection against UV induced cyclobutane pyrimidine dimer (CDP) formation, filtering UVB.[1]

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.
      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

  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
