Description of Chelating agent: metal ions are crucial to many important processes in living organisms. Many microorganisms also rely on metal ions to survive and grow. This is of course highly undesirable in formulations. To remedy this problem, one can kill the organisms by using preservatives. Another solution is to remove the metal ions from the formulation. This effectively inhibits microbe growth, prevents rancidity, and increases shelf life. Chelating agents are molecules that form highly stable bonds with metal ions, making them unusable by microorganisms. Glutamate TDA30 is an excellent, natural, amino-acid based chelating agent that is widely usable and very effective.
