Among the most commonly used meat preservatives are nitrates and nitrites. These compounds not only enhance the shelf life of cured meats like bacon and ham but also impart a characteristic pink/red color, which consumers often associate with freshness. Nitrates and nitrites work by converting into nitric oxide under certain conditions, which then inhibits the growth of spoilage bacteria. However, the use of these preservatives has raised health concerns, as they can react with amines in the meat to form potentially carcinogenic nitrosamines when exposed to high temperatures. As a result, regulatory agencies have set limits on their usage to ensure consumer safety while still allowing manufacturers to benefit from their preservative properties.
In addition to food, preservatives are also widely used in personal care products, such as lotions, shampoos, and cosmetics. Products that contain water are susceptible to microbial growth, making preservatives essential in these contexts as well. Parabens, which include methylparaben and propylparaben, are among the most commonly used preservatives in cosmetics. They serve to prolong the shelf life of products, preventing them from becoming contaminated and ensuring they remain safe for consumer use.

E504 can also be found in dietary supplements and various pharmaceuticals, given its role in improving the stability of ingredients. Its versatility allows manufacturers to incorporate it into a wide range of products, from snacks to beverages, enhancing both quality and longevity.
Natural Occurrence and Uses
In contrast, sodium carbonate has broad industrial applications. It is used in glass manufacturing, where it acts as a flux to lower the melting point of silica. This is crucial in the production of glass and ceramics. Sodium carbonate is also prevalent in the production of detergents and soaps due to its ability to soften water by removing calcium and magnesium ions. Furthermore, it plays a role in the treatment of water, where it helps in adjusting the pH, making it less corrosive to pipes and infrastructure.
