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.

Application
- To study the synergistic effect of Tergitol 15-S-7 and AOT (dioctyl sulfosuccinate) on bacterial oxidation of alkanes in crude oils[1]
- In cloud-point extraction technique to extract polycyclic aromatic hydrocarbons from aqueous solutions[2]
- Along with MgSO4 in anolyte reservoir for electrokinetic experiments[3]
- As a very efficient surfactant in removing non-polar oil[4]
- To study the phase behavior of surfactant-brine–oil system, which is desired for enhanced oil recovery[5]
Features and Benefits
- Excellent formulation & handling properties
- Superior wetting & rinseability
- Low odor
- Narrow gel range
General description
Tergitol 15-S-7 is a linear non-ionic surfactant that is a secondary ethoxylated alcohol.[6][7] It is compatible with anionic, cationic, and other nonionic surfactants.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
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
