General description

2-Ethylhexyl acrylate can undergo free radical solution polymerization to yield its polymer. [1] It can form a series of copolymers via atom transfer radical copolymerization. [2] A study reports the emulsion terpolymerization of the product with styrene, methacrylic acid. [3]
2-ethylhexyl acrylate (EHA) is one of the constituents of acrylic polymeric latex. [4]It can undergo free-radical solution polymerization.[1] EHA is known to undergo free radical emulsion co- polymerization with methyl methacrylate (MMA) to form pressure-sensitive adhesives. [5][6] It may also form copolymers with acrylonitrile and acrylamide. [7]

Application

  • Formulation optimization and stability study of transdermal therapeutic system of nicorandil.: This research explores the formulation and stability of a transdermal therapeutic system using 2-ethylhexyl acrylate (2-EHA) as a key component, highlighting its potential in delivering drugs through the skin effectively (Tipre DN et al., 2002).

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
