SAFETY PROFILE OF TETRASODIUM GLUTAMATE DIACETATE (GLDA):
The safety of Tetrasodium Glutamate Diacetate was assessed by the Expert Panel for Cosmetic Ingredient Safety (formerly called the Cosmetic Ingredient Review Expert Panel) in 2021.

The Expert Panel concluded that it was safe as used in the present practices of use and concentration in cosmetics and personal care products.
The Expert Panel noted Tetrasodium Glutamate Diacetate is slowly absorbed through the gastrointestinal tract and skin absorption is likely to be even slower.

The Expert Panel also noted the lack of carcinogenicity (cancer-causing potential) data and that it may contain a salt of nitrilotriacetic acid, a category 2B carcinogen according to the International Agency for Research on Cancer (IARC).
However, the concern was mitigated by multiple genotoxicity studies (both in vitro and in vivo), which did not indicate adverse genetic activity at the low concentrations of this ingredient in leave-on products.

ALTERNATIVES OF TETRASODIUM GLUTAMATE DIACETATE (GLDA):
*TRISODIUM ETHYLENEDIAMINE DISUCCINATE,

WHAT IS A CHELATOR OR SEQUESTRANT?
It is a substance consisting of molecules possessing two or more atoms that can bind to the same metal atom to form stable complexes.

DIFFERENCES BETWEEN TETRASODIUM GLUTAMATE DIACETATE (GLDA) AND EDTA:
Demonizing EDTA would be a mistake, but it must be said that some substances commonly used in cosmetics can, as of today, be replaced with more eco-friendly alternatives.

This is the case with EDTA, which has always been used as a chelator, especially in rinse-off products such as shampoos or detergents, because it also has an inherent cleansing action.

Studies, however, show that its metal sequestering action is, especially with regard to the marine ecosystem, very polluting because it allows greater dispersion of heavy metals into sea water, especially when used in everyday detergents.

In skincare cosmetics, the use of EDTAs definitely has a lower environmental impact especially because of their leave-on nature (they do not rinse off).

However, using more eco-friendly alternatives here as well, such as Tetrasodium Glutamate Diacetate (GLDA), is meant to be a support for future generations not to underestimate any aspect related to the environment.
