Uses disodium EDTA is a preservative used in concentrations of 0.1 to 0.5 percent.
Uses Disodium Dihydrogen EDTA is a sequestrant and chelating agent whose complete name is disodium ethylenediamine tetraacetate. it is a nonhygroscopic powder that is colorless, odorless, and tasteless at recommended use levels. A 1% solution has a ph of 4.3–4.7. It is used to control the reaction of trace metals to include calcium and magnesium with other organic and inorganic components in food to prevent deterioration of color, texture, and development of precipitates and to prevent oxidation. Its function is comparable to that of disodium calcium edta.
Uses Chelating agent (metal); pharmaceutic aid (chelating agent).
Uses Ethylenediaminetetraacetic acid disodium salt is widely used in textile industry. Usually applied to dissolve limescale. It is applied in textile industry, pulp and paper industry and also in chelation therapy. In cosmetics, it acts as a sequestering agent. It acts as a corrosion inhibitor to carbon steel in the industries. It also acts as a food additive.
Definition ChEBI: An organic sodium salt that is the anhydrous form of the disodium salt of ethylenediaminetetraacetic acid (EDTA).
Application Ethylenediaminetetraacetic acid disodium salt dihydrate has been in seed germination trials of plant species and in protein extraction from Moss, Physcomitrella paten. It has also been used in lysis and vacuole buffer for the isolation of vacuoles from Petunia petals.
Chelator of divalent cations. Inhibits enzymes, such as metalloproteases, that require divalent cations for activity.
