Trisodium EDTA
Ingredient Info
Trisodium EDTA is a chelating agent that binds to metals and minerals in cosmetic formulas, helping stabilize products and prevent them from breaking down. It's used in small amounts (typically under 2%) to maintain product consistency and shelf life.
Benefits
- Stabilizes cosmetic formulations and extends shelf life
- Prevents discoloration and degradation caused by trace metals
- Helps preserve product efficacy over time
Potential concerns
- May increase skin penetration of other ingredients by binding to calcium in skin
- Should be avoided in inhalable products (sprays, powders) due to potential respiratory concerns
- Not intended for ingestion or use in products applied to lips/mouth area
Science: The Cosmetic Ingredient Review Expert Panel confirmed safety in 2023 based on current practices and concentrations. While EDTA is not absorbed through intact skin, it can alter how other chemicals penetrate the skin by chelating calcium, so formulators must carefully consider ingredient combinations.
