Kaitseaineid

Kaitseaineid, which translates to "preservatives" in English, are substances added to products to prevent their decomposition by microbial growth or by undesirable chemical changes. They are commonly found in a wide range of consumer goods, including food, cosmetics, pharmaceuticals, and industrial products like paints and plastics. The primary purpose of preservatives is to extend the shelf life of these products, maintain their quality, and ensure their safety for use.

In food, preservatives play a crucial role in preventing spoilage caused by bacteria, yeasts, and molds, thereby reducing the risk of foodborne illnesses. Common examples include sorbates, benzoates, and nitrites. In cosmetics and personal care products, they prevent the growth of microorganisms that can cause product degradation and potential skin infections. Parabens, phenoxyethanol, and formaldehyde-releasing agents are frequently used examples. Pharmaceutical products also utilize preservatives to maintain sterility and efficacy over time.

The use of preservatives is subject to regulation in most countries to ensure their safety. Regulatory bodies evaluate preservatives for potential health risks and establish acceptable limits for their use in different product categories. While preservatives are highly effective in their intended role, some individuals may experience sensitivities or allergic reactions to certain types, leading to ongoing research and development of alternative preservation methods.
