What purpose do chelating agents serve in cosmetics?

To enhance fragrance
To preserve cosmetics
To color products
To emulsify ingredients

The correct answer is: To preserve cosmetics

Chelating agents serve primarily the purpose of preserving cosmetics by binding with metal ions that can cause product instability or deterioration. In formulations, metal ions can catalyze reactions that lead to product degradation, microbial growth, or color changes. By using chelating agents, formulators can improve the stability and shelf life of cosmetic products, ensuring that they maintain their intended qualities over time. This preservation is essential for both the effectiveness of the product and the safety of the consumer. While other functions like enhancing fragrance, coloring products, or emulsifying ingredients are important in cosmetics, they do not relate directly to the specific role of chelating agents.
