Tetrasodium
What Tetrasodium is & what it does
On a cosmetic label "Tetrasodium" almost always appears as the start of a fuller name such as tetrasodium EDTA or tetrasodium glutamate diacetate, used as a chelating agent. Chelators bind stray metal ions that would otherwise destabilize a formula, helping preserve clarity and shelf life and boosting the action of preservatives. They are used at very low levels. The standalone term carries no sun-protection function.
