Natural preservatives are ingredients that are found in nature and can — without artificial processing or synthesis with other substances — prevent products from prematurely spoiling. With growing awareness of side effects of chemical preservatives, consumers are looking for more natural and greener cosmetics, thus formulators are keen to have natural preservatives that are safe to use.
What Are Natural Preservatives Used for?
Manufacturers use natural preservatives to extend the shelf life of their products, reduce spoilage and retain smell or skin feeling. After all, the goods need to survive the shipping process, and they might be sitting in a store or warehouse for a while before someone buys them.
Natural preservatives are popular in natural brands of cosmetic products, including makeup and skin care cosmetics. These ingredients are also common in shelf-stable food products such as peanut butter and jelly.
To become available for consumption, most of these formulas need to pass a preservative efficacy test (PET) , also known as a “challenge test.” This process simulates natural contamination by injecting products with microorganisms. If the preservative succeeds in eradicating these organisms, the product is ready for market.
Like synthetic preservatives, natural preservatives fall within the category of what scientists and industry insiders often call a “preservative system.” This phrase refers to three ways preservatives tend to work, and we added antibacterial to make the list four total:
1. antimicrobial: inhibits the growth of microbes such as bacteria and fungi
2 .antibacterial: inhibits the growth of bacteria such as mold and yeast
3. antioxidants: delays or stops the process of oxidation (usually the beginning of something deteriorating because it is losing electrons)
4. acting on enzymes: stops aging of cosmetic products
