一般描述

对羟基苯甲酸甲酯基本上是对羟基苯甲酸的甲酯。它无毒，无致癌性。它是一种稳定的非挥发性化合物，可用作食品，药品和化妆品中的抗微生物防腐剂。本品易通过皮肤和胃肠道吸收。经水解后水解为对羟基苯甲酸，形成的结合物迅速排出尿液。[1]
对羟基苯甲酸甲酯是一种稳定的非挥发性[2]p-羟基苯甲酸甲酯[2][3]。 它可以作为食品、药品和化妆品中的广谱抗菌防腐剂应用。[2][3] 研究发现它属于非致癌物质，对霉菌和酵母菌以及细菌等真菌非常有效。[2][3]

应用

在一项应用微乳液电动色谱法(MEEKC)对食品防腐剂进行检测的实验研究中，对羟基苯甲酸甲酯被用作商业食品中的防腐标准。[4]

Questions

1–5 of 5 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
