EDTA

EDTA is a salt of ethylenediaminetetraacetic acid (commonly known as EDTA). In cosmetics, it functions primarily as a chelating agent, meaning it prevents ingredients in a formula from binding with trace elements (mainly minerals) that can be present in water or other ingredients. This action enhances the stability of cosmetics formulas and helps makes the job of preservatives easier since EDTA ingredients bond with mineral ions that microorganisms need to remain intact. In addition to being used in makeup, skin care, and hair care products, EDTA is also used as a food additive. It also helps to counteract the effects of hard water on surfactant containing products. Off-white powder, no odor. Easily soluble in cold water.
