What it is
Pentasodium pentetate is a water-soluble chelating (sequestering) agent that binds trace metal ions such as iron and copper in a formula. By tying up these metals, it helps prevent them from catalyzing oxidation and degradation, which supports product stability and the performance of preservatives. It is used at very low levels and has no direct effect on the skin itself.
Safety & warnings
Pentasodium pentetate is used at low concentrations as a chelator and is generally well tolerated. It is not a recognized fragrance allergen and is not considered comedogenic. Its role is purely functional within the formula rather than active on skin.
Origin & sourcing
Synthetic, made by neutralizing pentetic acid (DTPA) with sodium hydroxide.
Questions everyone asks
What is a chelating agent?
A chelating agent binds metal ions in a formula so they cannot trigger oxidation or interfere with preservatives, helping keep the product stable.
Does pentasodium pentetate affect the skin directly?
No. It works inside the formula to bind trace metals and is used at very low levels, with no intended action on the skin.
