What is the function of a chelating agent?

A chelating agent functions by binding to metal ions in a formulation, which plays a critical role in enhancing the efficiency of preservatives. Metals can catalyze the degradation of products, promote microbial growth, or destabilize a formulation. By breaking down cell walls and sequestering these metal ions, a chelating agent helps to maintain product stability and effectiveness. This is particularly important in cosmetics and skincare products, where the integrity and safety of the formulation are paramount.

While fragrance, shelf life, and color are important attributes in product formulation, they are not the primary function of a chelating agent. The primary role is related to the interaction with metal ions to ensure the overall quality and longevity of the product.
