Disodium EDTA can be classified as a co-preservative, protects the integrity of skincare products from undergoing unwanted consistency changes, pH changes, odour changes, or texture changes. Besides, when binding with calcium, iron, or magnesium, Disodium EDTA results in enhanced foaming and cleaning abilities. Another function of Disodium EDTA is to bind heavy metal ions and trace elements contained in tap water, which prevents these metals from being deposited onto the skin, hair, and scalp. While hard water is not harmful to your health overall, it can have a considerable effect on your hair and skin. Hard water can lead to product build-up in hair, cause colour-treated hair to wash out very quickly, and make hair more prone to breakage. Similarly, hard water makes it difficult to rinse away soap from the surface of your skin, leaving your skin dry and potentially irritated. Thus, disodium EDTA can help to counteract these adverse effects of hard water. This function of disodium EDTA makes it a particularly useful ingredient for rinse-off products that inherently require water to come into contact with the skin.

SUBSTITUTION
Tetrasodium EDTA 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.
Dermofeel PA-3 is natural chelator you can use if you prefer you want to avoid synthetic ingredient
