Disodium EDTA
Chelating agent that binds metal ions and improves formula stability by preventing product degradation, discoloration, and pH fluctuations.
Disodium EDTA is a chelating agent that binds to metal ions, preventing their destabilizing effects on cosmetic formulations.
It is commonly used to improve product stability by preventing the breakdown of surfactants and emulsifiers, as well as reducing discoloration caused by metals in the formula.
This ingredient is a must-have for water-based products such as shampoos, conditioners, toners, and lotions, where metal ions are more likely to be present.
FEATURES
- Metal ion binding – chelates metal ions to prevent instability and discoloration.
- Improves stability – reduces the risk of breakdown in surfactants and emulsifiers.
- Preserves formula integrity – helps prevent degradation and maintains clarity in aqueous formulas.
- Low dosage – effective at very low concentrations to stabilize and protect formulations.
BEST FOR
- Shampoos
- Conditioners
- Lotions
- Toners
- Facial cleansers
- Body washes
FORMULATION GUIDELINES
| INCI | Disodium EDTA |
|---|---|
| Type | Chelating agent |
| Solubility | Water soluble |
| Use Rate | 0.05–0.1% typical. Common dosage is 0.05% for toners and body washes, up to 0.1% for thicker formulations like shampoos. |
| pH Compatibility | Works across a wide pH range, but is most effective in formulations with a pH of 4.0–7.5. |
| Temperature Tolerance | Stable under normal processing conditions. We recommend adding in cool down below 45°C for maximum stability. |
| Pro Tip | Disodium EDTA helps prevent discoloration and degradation of sensitive ingredients like surfactants and essential oils. It is especially effective in water-based formulations with a higher metal ion content, such as tap water-based products. Ensure proper dissolution in your formula to avoid clumping, and balance with other stabilizers or preservatives as needed. |
| Appearance | Clear, colorless to pale yellow liquid |
| Stability Notes | Very stable in a wide range of products. However, it should not be used at high concentrations in products with a high acid content. |
| Storage | Keep sealed, cool, and dry, away from direct sunlight. Protect from freezing. |
