Disodium EDTA is a white crystalline powder which is odourless and has a slightly salty flavour. It is also known as edetic acid. You will frequently find this name in the skincare and haircare products. Sometimes the name Disodium EDTA gets replaced by EDTA on the label of the beauty products. EDTA stands for ethylenediaminetetraacetic acid. It comes under a special class of chemicals called the chelators. Chelators are chemicals which react with the metal ions in such a way that it minimizes the effects of the metals and minerals with which it is bonded, thus, preventing chemical reactions which may cause deterioration of colour or flavour.

Disodium EDTA is popularly known as a chelating agent and acts as a water-soluble acid which is a strong emulsion stabilizer. It is mainly used in cosmetic products for controlling viscosity. EDTA binds with the metals ions and deactivates them, thus preventing your cosmetic products and other personal care products from degrading or deteriorating. It is extensively used in creams, body lotions, sunscreens, shampoos, conditioners, styling gels, hair styling sprays and serums. Disodium EDTA preserves cosmetic products and personal care products from undergoing unwanted changes in texture, colour, pH levels and fragrance. Apart from binding with metals such as calcium, iron or magnesium, Disodium EDTA helps in enhanced foaming and also exhibits cleansing property.
