Chelating Agents
Chelating agents have been widely used in cosmetics. Their main function is to chelate metal ions in raw materials or water to prevent these metal ions from causing adverse effects on products such as rancidity, precipitation and inactivation.
Iron ions are very important to microorganisms. Iron is one of the most important nutrient sources for microorganisms. It is the redox center of iron-sulfur proteins in the electron transport chain and participates in the reduction reaction of nucleotide precursors.
