Chelating

Disodium EDTA

The invisible protector of formulas — EDTA binds metal ions in water and prevents cosmetic spoilage. This chelating agent is present in almost every cream or lotion to ensure the stability and effectiveness of the product.

What is it?

Disodium EDTA (ethylenediaminetetraacetic acid) — a synthetic chelator. It binds divalent metal ions (Ca²⁺, Mg²⁺, Fe²⁺) in water, which hinder the action of preservatives and catalyze oxidation. It enhances the effectiveness of preservatives and prevents changes in color and odor. In INCI: Disodium EDTA.

A standard component of almost any water-based formula — cream, lotion, toner, shampoo. One of the most common excipients in cosmetics.

Key Benefits

✦

Enhancement of preservative action

EDTA binds metal ions that inactivate preservatives — phenoxyethanol, parabens, and others. Without EDTA, preservatives are less effective, especially in hard water.

◈

Stabilization of color and fragrance

Iron and copper ions catalyze oxidation, changing the color and odor of the product. EDTA chelates them — the product maintains its appearance throughout its shelf life.

✧

Protection against microbial growth

Weakens the membranes of certain bacteria by removing calcium from the structure of cell walls — a synergistic antimicrobial effect together with primary preservatives.

EDTA and ecology

Disodium EDTA poorly biodegrades in water bodies and can mobilize heavy metals in the soil — the main ecological criticism. Alternatives: tetrasodium glutamate diacetate (Glda, a natural analogue), phytic acid. Safe for skin at regulated concentrations.
