General description

Arquad® 2HT-75 or di(hydrogenated tallow)dimethylammonium chloride is a cationic surfactant used as an emulsifying, foaming, and wetting agent in various chemical industries. It is also used to form complexes with anionic species with exceptionally low water solubility results in flocculation, ion exchange, and decolorization characteristics that are useful in a variety of applications including water treatment, sugar refining, and the synthesis of organoclays.

Application

Arquad® 2HT-75 can be used as a dispersing agent in the preparation of nanocomposites to reduce surface tension between polymer and the filler.[1] It is also used to develop bio-reactive organoclays because it is less toxic to soil microorganisms than other commonly used surfactants.[2]

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
