Ethylene diamine tetraacetic acid (EDTA)
EDTA chelates a variety of metal ions. It improves the performance of shampoos and eliminates formation of unwanted scum. In detergents, it helps improve washing performance by forming complexes with Ca2+ or Mg2+. As a stabilizer, it prevents ingredients in a given formula from binding with trace elements (particularly minerals) that can exist in water and other ingredients to cause unwanted product changes such as texture, odor, and consistency problems.
Disodium ethylene diamine tetraacetic acid (Disodium EDTA)
Disodium EDTA chelates a variety of metal ions. Like other forms of EDTA, it can be used in a variety of products from shampoo, to detergents, to hair dye. It is available as a salt for specific formulating needs.
