Trisodium dicarboxymethyl alaninate

Trisodium dicarboxymethyl alaninate (CAS 164462-16-2), also known as DL-Alanine-N,N-diacetic acid trisodium salt, is a biodegradable aminopolycarboxylate chelating agent derived from alanine.

It sequesters calcium, magnesium, and heavy metal ions across a broad pH range, enabling formulators to replace conventional chelants such as EDTA in environmentally sensitive applications.

In personal care, it stabilizes formulations by deactivating trace metals that would otherwise degrade active ingredients or cause discoloration in shampoos, lotions, and liquid soaps.

Home care and industrial cleaning products rely on it to prevent limescale redeposition and boost surfactant performance in hard-water conditions during various cleaning cycles.

Water treatment applications use it to control metal ion interference in process water and cooling systems where biodegradability is a regulatory or operational requirement for the facility.

Its compatibility with alkaline cleaning systems also makes it suitable for CIP formulations in food processing environments where high performance and safety are essential for operations.

Trisodium dicarboxymethyl alaninate is typically supplied as an aqueous solution, with active content concentrations commonly available in the 30 to 40 percent range for industrial use.

Technical and industrial grades are the standard market offering, with product specifications aligned to chelant performance parameters such as active content, pH, and iron content limits.
