Disodium EDTA
Price range: ₦2,500.00 through ₦25,000.00
Disodium EDTA is commonly used in neutral to mildly acidic products, like most creams, lotions, and neutral pH liquid soaps and shampoos.
EDTA, Ethylenediaminetetraacetic acid is a molecule that complexes metal ions in aqueous environments. It is available in four neutralization, two of which, Disodium EDTA and Tetrasodium EDTA, are commonly used in cosmetics. Generally, the choice of which product to use is determined by the pH of your product, but this is not a hard and fast rule. Disodium EDTA is commonly used in neutral to mildly acidic products, like most creams, lotions, and neutral pH liquid soaps and shampoos. EDTA works synergistically with your preservative to improve preservative efficacy.
Disodium EDTA
has limited solubility in water, but at a typical usage rate of 0.2% to improve preservative efficacy, even if not fully solubilized, 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 low usage rates, it will not raise the pH unduly, but if it does, you can simply lower the pH of your formulation with a citric acid solution.
