Widely used in cosmetics and personal care products, including shampoos, lotions, liquid soaps, and hair care formulations, as a chelating agent to improve stability by binding metal ions that can cause product degradation. Helps prevent discoloration, odor changes, rancidity, and oxidation, extending shelf life.

Commonly added to industrial cleaning solutions, including contact lens cleaners, to enhance performance by sequestering calcium and magnesium ions, thus preventing scale formation, dirt buildup, and improving the efficiency of surfactants and detergents.

Employed in the textile industry to control metal ions that may cause color bleeding or changes during dyeing processes.

Used in water treatment processes to control metal ion activity, especially in systems where hard water is a concern. It helps maintain equipment efficiency and prolongs the life of membranes and boilers.

Employed in some pharmaceutical formulations to stabilize active ingredients and protect against metal-catalyzed degradation, ensuring longer shelf life and consistent efficacy.

Also utilized in certain laboratory applications, such as buffer systems requiring strong metal ion control without acidification, and as an inhibitor for enzymes that require magnesium or calcium ions by sequestering these from solution. Particularly suitable as a high-pH-stable chelator.
