Pentasodium Pentetate
What is Pentasodium Pentetate?
Pentasodium pentetate is the pentasodium salt of diethylenetriaminepentaacetic acid, a fully synthetic polycarboxylic acid chelator developed for use in personal care products. It belongs to the aminopolycarboxylate family of chelating agents and is commonly incorporated into cosmetics like cleansers, shampoos, lotions, and creams at low levels. In formulations, it functions by tightly binding divalent and trivalent metal ions—such as calcium, magnesium, copper, and iron—from water or ingredients. This sequestration inhibits metal-catalyzed reactions that cause oxidation, precipitation, rancidity, or loss of clarity, thereby preserving the product's texture, color, scent, and performance throughout shelf life and use. Its high affinity for heavy metals makes it effective even in challenging water conditions.
