Chemical additives are substances added to products to enhance their properties or performance. They are commonly used in various industries, including food, pharmaceuticals, and cosmetics. For example, in food products, additives can serve as preservatives, flavor enhancers, or colorings, ensuring safety and improving taste. These additives can be natural or synthetic and are regulated by organizations like the Food and Drug Administration (FDA) to ensure they are safe for consumption. While they play a crucial role in product formulation, it is important for consumers to be aware of the ingredients in the products they use and their potential effects on health.
