Application

  • Effect of leave-on cosmetic antimicrobial preservatives on healthy skin resident Staphylococcus epidermidis.: This study examines the impact of various antimicrobial preservatives, including 2-Bromo-2-nitro-1,3-propanediol, on the microbiota of healthy skin, particularly focusing on Staphylococcus epidermidis. The findings suggest that such preservatives can influence the skin′s microbial balance, which is essential for maintaining skin health (Zhang et al., 2023).
  • Assessing the residual antibacterial activity of clinical materials disinfected with glutaraldehyde, o-phthalaldehyde, hydrogen peroxide or 2-bromo-2-nitro-1,3-propanediol by means of a bacterial toxicity assay.: This research assesses the residual antibacterial effects of various disinfectants, including 2-Bromo-2-nitro-1,3-propanediol, on clinical materials, contributing to improved disinfection protocols in healthcare settings (Lerones et al., 2004).
  • Development and testing of a microbiological assay to detect residual effects of disinfectant on hard surfaces.: This study developed a microbiological assay to evaluate the residual effects of disinfectants, including 2-Bromo-2-nitro-1,3-propanediol, on hard surfaces, aiming to enhance surface disinfection strategies in various industries (Mariscal et al., 1999).

Medical-grade polyvinyl chloride was surface modified by a multistep physicochemical approach to improve bacterial adhesion prevention properties. This was fulfilled via surface activation by diffuse coplanar surface barrier discharge plasma followed by radical graft copolymerization of acrylic acid through surface-initiated

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/449/386/product-dating-information-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
