Caution
EDTA Di-Sodium is a salt of edetic acid and is used as a preservative, stabiliser, and foaming agent in various personal care products, as well as a chelator. Chelators or chelating agents bind to mineral ions and inactive them. As a result, they counteract the negative effects of hard water by binding with heavy metal ions contained in tap water and preventing the metals from being deposited onto the skin, hair, and scalp.
As a preservative, this ingredient works by preventing the growth of bacteria. It also improves the foaming and cleansing abilities of products by forming complexes with the calcium, magnesium, and iron present in water. These complexes form and prevent the build-up of their minerals on the skin or hair. It appears as a water-soluble, odourless crystalline powder.
