In shampoos, cleaners and other personal care products EDTA salts are added as a sequestering agent to improve their stability in air.
EDTA is used as a chelating agent that binds to calcium and prevents joining of cadherins between cells, preventing clumping of cells grown in liquid suspension, or detaching adherent cells for passaging.
