EDTA (Ethylenediaminetetraacetic acid) is sometimes used in skin and hair products for its conservative and stabilizing properties.

However, this molecule can also act as a penetration enhancers for many other ingredients, which makes them more likely to penetrate skin. This may thus then modify the safety of ingredients which is based on the fact that they do not penetrate the skin epidermis. EDTA is also particularly efficient at binding metals such as Nickel and Chromium, then bringing them inside the body through skin; this may therefore trigger rashes and other health issues to people with allergy to these metals, a very common situation.

As a general rule, it is therefore safest to not use products that contain EDTA if one has sensitive or reactive skin.
