Trisodium Hedta
What is Trisodium Hedta?
Trisodium HEDTA, the trisodium salt of N-(2-hydroxyethyl)ethylenediamine-N,N',N'-triacetic acid, is a synthetic compound designed for use in cosmetics and personal care items. It belongs to the category of chelating agents, commonly found in shampoos, conditioners, cleansers, and moisturizers. This ingredient works by forming stable complexes with metal ions like calcium, magnesium, iron, and copper present in water or raw materials. By binding these ions, it prevents unwanted reactions such as color changes, odor development, or emulsion breakdown, thereby extending shelf life and maintaining product efficacy. It also aids in keeping formulations clear and consistent. In rinse-off and leave-on products, it helps control trace metals that could otherwise interfere with performance or texture.
