What is Trisodium NTA?

Trisodium NTA is a chelating agent, which means it's used to bind and stabilize metal ions in formulations. It is synthesized chemically by neutralizing nitrilotriacetic acid with sodium hydroxide.

In skin care, it is often included to enhance stability and prevent the formation of insoluble salts. However, there are some health concerns about its potential as a skin irritant and ability to chelate essential metal ions in the body, potentially interfering with nutrient absorption.

When you see Trisodium NTA on a label, it's typically there for its ability to enhance the efficacy and stability of the product. Although some studies have raised concerns, regulatory bodies maintain its limited use as safe under specific conditions.

Commonly found in: facial cleansers, shampoos, body washes, soaps, detergents
