What is the purpose of Tetrasodium EDTA in cosmetics?
Tetrasodium EDTA acts as a chelating agent, meaning it binds to metal ions that can be present in water or other ingredients. This prevents these metal ions from causing product instability, discoloration, or reducing the effectiveness of other ingredients.
Is Tetrasodium EDTA safe for skin?
It is generally considered safe for topical use in cosmetic formulations at typical concentrations. However, some concerns exist regarding its potential to enhance the penetration of other ingredients into the skin.
