Application

Dioctyl sulfosuccinate sodium salt (DOSS) can be used as an anionic surfactant:
  • To prepare microemulsion with sodium salt of 3-(cyclohexylamino)-2-hydroxy-1-propanesulfonic acid (CAPSO) for the electrophoresis detection of natural and synthetic estrogens.[1][2]
  • To develop reverse micelles.[3]
  • To enhance the electrical conductivity and cell attachment in polycaprolactone fumarate and polypyrrole (PCLF–PPy) composite materials.[4]

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

    My dishwashing sponge has less water than the Dioctyl Sulfosuccinate you sell. Soaking wet DS salt. Dank!

    How do you store your salt? It has so much water in it. I have to dry it a lot. Try to store it in a drier place. Most AOT labs use need it in a dry form. Fortunately my lab is blessed with a beautiful oven where I can dry it.
