The main reason for using preservatives in cosmetic products is to prevent the growth of microorganisms in these products. For this purpose, preservatives such as salicylic acid, sodium benzoate, sodium dehydroacetate, potassium sorbate, phenoxyethanol and parabens are used in cosmetic products. Today, with national and international standards, restrictions have been imposed on the amount of each preservative added to cosmetics according to the purpose of use. High performance liquid chromatography (HPLC) technique is generally used to investigate the actual conditions of the preservatives used.
Whether the preservatives used are safe is always a concern for consumers. These cosmetic products are considered safe as long as the right preservatives are used. Although there are preservatives that are thought to be irritating and carcinogenic, there are also preservatives that do not have such serious side effects.
In short, preservatives prevent the formation of yeast, bacteria and mold. This is why their preservatives are known as antimicrobials or antibacterials. Cosmetic products are particularly susceptible to the growth of bacteria and similar microorganisms because they contain a lot of water and water is the main habitat of these organisms.
Some preservatives are also added to foods to combat spoilage caused by bacteria, molds, fungi and yeasts. These preservatives keep food fresh longer and extend shelf life. Food preservatives are also used to slow or prevent changes in color, taste or texture and delay rancidity.
The use of preservatives in food products is strictly monitored and examined by official bodies . Legal regulations require evidence that food additives are safe for their intended uses. In this respect, scientific understanding and testing methods continue to evolve.
Preservatives used in foods are made from natural chemicals such as salt or alcohol, but also man-made or synthetic chemicals are used. Natural or organic chemicals are not necessarily healthier than synthetic or man-made chemicals. In fact, artificial preservatives such as sodium nitrate, sodium benzoate and propionate have long been used in food preparation as they are effective in small amounts.
