säilitusvahend

Säilitusvahend is the Estonian word for preservative. Preservatives are substances added to products like food, cosmetics, and pharmaceuticals to prevent spoilage caused by microorganisms. This spoilage can manifest as changes in color, odor, texture, or even the growth of harmful bacteria, yeasts, and molds.

In food, preservatives help extend shelf life and maintain quality. They work by inhibiting or slowing down the growth of microbes. Common examples include salt, sugar, vinegar, nitrates, sorbates, and benzoates. The use of preservatives in food is regulated to ensure safety for consumers.

Cosmetics also utilize preservatives to prevent microbial contamination that could occur during manufacturing or use. This is crucial for product safety and efficacy, especially for products applied to the skin. Common cosmetic preservatives include parabens, phenoxyethanol, and formaldehyde releasers.

Pharmaceuticals rely on preservatives to maintain the sterility and stability of liquid medications, vaccines, and other formulations. These preservatives prevent the growth of microorganisms that could compromise the drug's potency or cause infections.

The effectiveness of a preservative depends on its chemical properties and the environment in which it is used. Different preservatives target different types of microorganisms and are effective within specific pH ranges and temperatures. While preservatives are essential for product longevity and safety, some individuals may have sensitivities or allergies to certain preservative compounds.
