Tetrasodium glutamate diacetate (TSGDA) is a common preservative in beauty products, labeled “safe” by the FDA but linked to skin irritation, hormone disruption, and kidney damage. Often hidden under obscure names, it’s used in major brands like Dove and Neutrogena as a replacement for EDTA. Studies show TSGDA can bioaccumulate and cause harm, especially when combined with other chemicals. Safer alternatives exist, but weak U.S. oversight means consumers must demand cleaner, transparent products.
