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
- Enamel Matrix Derivative, 58S5 Bioactive Glass, and Fluoride Varnish for Enamel Remineralization: A Multi-analysis Approach.: This study explores the effectiveness of various agents including ethylenediaminetetraacetic acid (EDTA) in enamel remineralization processes, providing insights into dental applications of EDTA (Gungor et al., 2024).
- Mathematical modeling of rare earth element separation in electrodialysis with adjacent anion exchange membranes and ethylenediaminetetraacetic acid as chelating agent.: This research investigates the use of EDTA as a chelating agent in the separation of rare earth elements, highlighting its industrial applications in electrodialysis processes (Ding and Azimi, 2024).
- Comparative effects of 17% ethylenediaminetetraacetic acid and 9% etidronic acid applied with different irrigant activation techniques on the release of growth factors from dentin: in vitro study.: This paper examines the release of growth factors from dentin when treated with EDTA, contributing to the understanding of its role in dental health and regeneration (Mumcu et al., 2024).
- EDTA functionalized pine needle biochar (EDTA@BC); a valorized bio-material for removal of Ni(II) from aqueous solution.: The study showcases the use of EDTA-functionalized biochar for the removal of heavy metals from water, emphasizing its significance in water treatment applications (Rasheed et al., 2024).
- Impact of using XP-endo finisher and nanobubble water during EDTA dentin conditioning on TGF-beta1 release in regenerative endodontic procedures.: This research highlights the application of EDTA in enhancing the release of TGF-beta1, important for regenerative dental therapies (Hanafy et al., 2024).

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
