Aplicación

  • Thermal decomposition characteristics of BHT and its peroxide (BHTOOH): BHT is highlighted for its excellent antioxidant properties, which degrade into BHTOOH under specific conditions (S Dai, et al., 2024).
  • Relaxation mechanisms in low-stress polymer networks: BHT is utilized in polymer networks to assess its effects on the mechanical properties and durability of dental composites (SH Lewis, et al., 2024).
  • Compatibility and safety of labels for pharmaceutical packaging: The study found BHT in labels, indicating its widespread use in pharmaceutical packaging due to its stabilizing properties (C Fu, et al., 2023).

Acciones bioquímicas o fisiológicas

Butylated hydroxytoluene (BHT) is a phenolic antioxidant. It has been shown to inhibit lipid peroxidation. It causes lung injury and promotes tumors in mice, but this may be due to a metabolite of BHT, 6-tert-butyl-2-[2′-(2′-hydroxymethyl)-propyl]-4-methylphenol. Metabolites of BHT have also been reported to induce DNA strand breaks and internucleosomal DNA fragmentation (a characteristic of apoptosis) in cultured cells. In rats, a single intraperitoneal injection of BHT (60 mg/kg body mass) results in a significant increase in nuclear DNA methyl transferase activity in the liver, kidneys, heart, spleen, brain and lungs. Incubation of alveolar macrophages with BHT significantly reduced the level of TNF-α which may explain the mechanism by which this antioxidant reduces inflammation. Preincubation of aspirin-treated platelets with BHT inhibits the secretion, aggregation, and protein phosphorylation induced by protein kinase C activators. BHT was also found to inhibit the initiation of hepatocarcinogenesis by aflatoxin B1.

Questions

1–2 of 2 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.
      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
