Disodium EDTA and Triethanolamine
Disodium EDTA and triethanolamine is a functional pairing of a metal-ion chelator with a buffering/neutralizing amine. It controls pH, sequesters trace metals, improves clarity, and keeps surfactant systems stable across storage and use.

Our take
Is Disodium EDTA and Triethanolamine a Good Ingredient?
Good, because the combination manages pH and metal ions effectively to keep formulas stable and predictable. The rating is held to Good rather than Great because triethanolamine may irritate some skin and must be formulated carefully to avoid nitrosamine formation.
What it does
Skin Benefits
Maintains consistent viscosity, clarity, and foaming by moderating pH and tying up interfering ions. Can extend preservative and antioxidant performance.
Where you'll find it
Uses in Skincare & Cosmetics
Used in gel cleansers, liquid soaps, shampoos, and light lotions to stabilize appearance and in‑use feel.
Before you use it
Safety
May cause mild skin or eye irritation at higher concentration or pH. Should not be combined with nitrosating agents and must be controlled to be nitrosamine‑free per regulatory guidance. Patch test leave‑on products if sensitive.
