The most common type of chemical preservatives used for food and beverages are sulphites, nitrates, propionates, sorbates, benzoates, and lactic acid. These compounds are added to the food to help prevent the growth of bacteria and delay the growth of mold.

Additionally, chemical preservation is also used in products such as medicines, cosmetics, and pharmaceuticals. In the case of medicines and pharmaceuticals, chemical preservation helps to maintain the active components of the product, thus preserving its potency.
