Ethylenediaminetetraacetic Acid Disodium Salt (EDTA 2NA) is a widely used chelating agent in personal care, household, and industrial applications. Renowned for its ability to bind metal ions, EDTA 2NA enhances product stability and performance across various formulations. This blog explores the properties, applications, and benefits of EDTA 2NA, shedding light on why it remains a staple in modern chemical formulations.
What is EDTA 2NA?
EDTA 2NA is the disodium salt of ethylenediaminetetraacetic acid, a powerful chelating agent that binds to metal ions such as calcium, magnesium, and iron. By sequestering these ions, EDTA 2NA prevents unwanted reactions in formulations, such as discoloration, precipitation, or loss of efficacy. Its versatility and safety profile make it a key ingredient in diverse industries.
