What does this ingredient do in an antiperspirant?
A chelating agent: according to CosIng it binds metal ions that could impair the stability or appearance of a cosmetic. Structurally it is the sodium salt of a glutamic acid derivative carrying two acetate groups.
Part of a system, not a label in isolation
In the catalog it appears in water-based roll-ons and sprays. It acts as a stabilizer at a small share of the formula and does not reduce sweating.
In 2025 the CIR Expert Panel concluded that Tetrasodium Glutamate Diacetate is safe in cosmetics in the practices of use and concentration described.
The CIR assessment found no grounds to consider it unsafe under the described conditions. As with any ingredient, an individual reaction cannot be ruled out.
Not the same as Tetrasodium EDTA or Disodium EDTA: they share the job of binding metals but are structurally different substances.
