Name
Disodium EDTA
Description
Disodium EDTA (Ethylenediaminetetraacetic Acid Disodium Salt) is a common chelating agent used in cosmetics, personal care products, and even food and pharmaceuticals. It is a salt form of EDTA and its main function is to bind with metal ions. By doing so, it prevents these metals from destabilizing or degrading products, thus enhancing their shelf life and efficacy.
Benefits
Improves performance of surfactants and aids in formula stability.
Considerations
• Acute Toxicity
Harmful if swallowed or exposed to in high amounts. May cause organ damage.
• Skin Irritation
May cause skin irritation or allergic reaction.
• Eye Irritation
May cause eye irritation.
• Respiratory Toxin
Harmful if inhaled.
• Environmental Toxicity
Harmful to aquatic life with long-lasting effects. Not readily biodegradable.
• Contamination Concerns
Disodium EDTA can theoretically form certain nitrosamines, a class of carcinogenic chemicals.
