Colour & Appearance: A white powder
Stable in pH range: 4-6
Grade: Cosmetic
Recommended Usage0.1-0.3%
Compatibility: It is compatible with other cosmetic ingredients.
Solubility: Chelating agents should be added to the water phase of formulations early in the formulating process so product degradation can be prevented before it begins. EDTA chelating agents are only soluble in aqueous solutions and have only limited solubility in acidic media below pH 3.5
Application: Disodium EDTA is commonly used in neutral to mildly acidic products, like most creams, lotions, and neutral pH liquid soaps and shampoos.
Note: Disodium EDTA has good solubility in water, but can take time to fully dissolve (15 – 30 minutes, or longer, depending on concentration). At a typical usage rate of 0.2% to improve preservative efficacy, even if not fully solubilized prior to incorporating it into your formulation, it is still efficacious. In creams or lotions, there will be no grittiness and it will not be seen. In clear or transparent gel, serum, or clear surfactant systems, use Tetrasodium EDTA, which is highly soluble in water. At Higher pH of about 8 and above, EDTA completely dissolves, you can simply lower the pH of your formulation with a citric acid solution.
Recommended Storage: Our powders should be stored in cool temperatures away from direct sunlight and moisture in an airtight container. (Current Lot will expire: 02-2028)
