Natural preservatives are ingredients that are found in nature and can — without artificial processing or synthesis with other substances — prevent products from prematurely spoiling. These substances can be safe, effective alternatives to controversial synthetic preservatives such as parabens. There are no federal laws that define what natural preservatives are. To avoid legal risks, some corporations instead claim “no artificial preservatives,” according to Campo Verde Solutions Founder Kim Greenfeld, who has decades of experience in the organic food industry. Because of this lack of regulation around the term, people have made assumptions about what natural preservatives are and how they work. Some consumers have believed, for example, that vitamin E can act as a natural preservative. In reality vitamin E, even in its oil form, is only useful as a supplement and skin treatment. https://eu.echemi.com/info/natural-preservatives-what-you-need-to-know_110304.html
