Disodium edetate
Chelating agent
Disodium edetate, also known as ethylenediaminetetraacetic acid disodium salt, is a chelating agent commonly used in healthcare and personal care products. It can be used to sequester and bind metal ions, such as calcium and magnesium, which can cause instability and degradation in cosmetic and pharmaceutical formulations.
Disodium edetate has been approved by the FDA for use in topical, ophthalmic, and injectable formulations. It is often used in eye drops to help prevent the discoloration of contact lenses and in intravenous solutions to prevent the precipitation of certain drugs.
However, it should be used cautiously as it can also chelate essential metal ions, such as zinc and copper, which may lead to adverse effects in the body. It can also decrease the effectiveness of certain medications by chelating with them, making them unavailable to the body.
Overall, disodium edetate is a useful chelating agent that can improve the stability and efficacy of healthcare and personal care products, but it should be used with caution and under professional guidance.
