Disodium Edta ●
TL;DR. This ingredient is a chelating agent that binds metal ions in water and formulas. It helps protect color, clarity, fragrance, and preservative performance by reducing metal-driven instability.
What does Disodium Edta do in a cosmetic formula?
This ingredient is a chelating agent that binds metal ions in water and formulas. It helps protect color, clarity, fragrance, and preservative performance by reducing metal-driven instability.
Is Disodium Edta clean?
From a clean-beauty perspective, this ingredient often has friction because it is synthetic and commonly flagged on restricted lists. Direct skin irritation is usually low at typical cosmetic levels, but the main concern is environmental persistence rather than topical tolerance.
Is Disodium Edta sustainable?
This material is typically made from petrochemical-derived feedstocks and is not readily biodegradable. Its ability to bind metals can also complicate wastewater and aquatic fate assessments.
Is Disodium Edta COSMOS-approved?
It is generally not permitted under COSMOS natural or organic standards. Its profile is weak from a Green Chemistry perspective because it relies on synthetic feedstocks and has poor biodegradability despite being used at low levels.
How does Disodium Edta work chemically?
The molecule is a small polycarboxylate salt with multiple binding sites that strongly complexes calcium, magnesium, iron, and copper ions. Typical use levels are about 0.01% to 0.2%, and it remains effective across a broad pH range while improving preservative robustness and reducing metal-catalyzed oxidation.
