Sodium EDTA
What is Sodium EDTA?
Sodium EDTA, or disodium ethylenediaminetetraacetate, is a synthetic compound derived from ethylenediamine and acetic acid. It functions primarily as a chelating agent in cosmetics, particularly in water-based products like cleansers, shampoos, lotions, and creams. By forming stable complexes with metal ions such as calcium, magnesium, and iron, it prevents these ions from catalyzing oxidative reactions that lead to product degradation, discoloration, or separation. This action maintains emulsion stability, improves clarity, and boosts the effectiveness of preservatives. Typically used at low levels, it is colorless, odorless, and water-soluble, making it ideal for personal care formulations where consistent performance is essential.
Benefits
Enhances product stability by binding metal ions that cause breakdown.
Prevents discoloration and rancidity in formulations.
Supports preservative function for longer shelf life.
Who It's For
A quick guide for who this ingredient may suit (and who should be cautious).
| Who May Benefit | Who Should Avoid |
|---|---|
| Users of water-based skincare like cleansers and lotions. | Those with confirmed rare sensitivity to chelating agents. |
| Individuals with products prone to separation or oxidation. | People preferring completely natural or mineral-free products. |
| All skin types seeking stable, high-quality formulations. | Individuals avoiding synthetic preservatives stabilizers. |
Safety Notes
- Rated low hazard by safety assessments for cosmetic use.
- Minimal skin penetration due to large molecular size.
