Chelating agents serve a crucial role in skincare products by enhancing the effectiveness of preservatives. Their primary function is to bind with metal ions that could otherwise compromise the stability and efficacy of the preservatives used in formulations. By doing this, chelating agents help prevent the growth of bacteria and fungi, ensuring the product remains safe and effective for consumers over its lifespan.

This interaction not only extends the shelf life of the product but also maintains the overall quality, performance, and integrity of the formulation. As a result, using chelating agents contributes significantly to the overall safety and effectiveness of skincare products in containing potentially harmful contaminants.

The other options provided (blocking pores, improving texture, and providing hydration) refer to different functions that may be accomplished by other ingredients but do not accurately describe the primary role of chelating agents within skincare formulations.
