Ingredient Info

Disodium EDTA is a chelating agent that binds to metals and minerals in skincare formulations, helping to preserve product stability and extend shelf life. It's used in small amounts (typically under 2%) to prevent unwanted chemical reactions that could degrade the formula.



Benefits

  • Stabilizes cosmetic formulations by binding trace metals
  • Extends product shelf life and maintains efficacy
  • Allows other skincare ingredients to work more effectively

Potential concerns

  • May increase skin penetration of other ingredients by chelating calcium in the skin barrier—only a concern if combined with potentially harmful substances
  • Not absorbed through skin in normal use, but inhalation from sprays was identified as a theoretical concern in safety assessments

Science: The Cosmetic Ingredient Review Expert Panel confirmed safety in 2023 based on standard use concentrations. Clinical studies show no skin absorption; however, it can affect how other chemicals penetrate the skin, so formulators must account for this when combining with other actives.
