The general consensus is yes. The U.S. Food & Drug Administration (FDA) and the watchdog organization CSPI agree that potassium sorbate is generally safe to consume. The additive doesn't accumulate in the body — instead, it breaks down into carbon dioxide and then water in the body, according to the ​Encyclopedia of Food Sciences and Nutrition​.

Furthermore, environmental considerations are also paramount in the usage of acetone. As a volatile organic compound (VOC), it contributes to air pollution and can lead to harmful effects on both human health and the environment. It’s vital for industries to adhere to regulations concerning the use of acetone, minimizing emissions and exploring alternatives that maintain product efficacy while reducing ecological impacts.

Potassium Sorbate: How it works, when it doesn’t work, and how much is too much

If you’re not familiar with the chemical potassium sorbate, then you are probably someone who doesn’t often read product labels. Potassium sorbate is used in tons of products as a preservative – from foods, to cosmetics, to pharmaceuticals. It has GRAS (Generally Recognized as Safe) status and is widely regarded as a safe, all-purpose antimicrobial and anti-fungal agent. Next time you’re snacking on some dried fruit, check the label for potassium sorbate – it might also be listed as E – 202. (It is almost never referred to by its IUPAC name, 2,4-hexa-2,4-dienoate.)
