Pentasodium Pentetate
What Pentasodium Pentetate is & what it does
A chelating agent that binds metal ions to keep formulas stable and protect preservatives. It safeguards clarity and shelf life.
Is Pentasodium Pentetate safe?
Pentasodium Pentetate is widely used in cosmetics at low concentrations and is generally considered safe for use in rinse-off and leave-on products. It is a chelating agent, meaning it binds trace metal ions, and it works in very small amounts. As with any ingredient, sensitivities can vary, so patch testing is reasonable if you have reactive skin.
What does Pentasodium Pentetate do in skincare?
Pentasodium Pentetate acts as a chelating agent in skincare and sunscreen formulas. It binds metal ions such as iron and calcium that can enter a product from water or raw materials, which helps preserve stability, prevent discoloration, and keep preservatives and antioxidants working effectively. It is used at very low levels purely as a formulation aid.
Is Pentasodium Pentetate natural or synthetic?
Pentasodium Pentetate is a synthetic ingredient. It is the pentasodium salt of pentetic acid (DTPA), produced through industrial chemical synthesis. It does not have a direct natural plant or mineral source.
