Potassium benzoate is a preservative that is commonly added to food, beauty and skin care products to extend their shelf life. Although this compound is approved for use in many countries, its potential side effects range from severe allergic reactions to ADHD to an increased risk of cancer.


The following gives an overview of potassium benzoate, which foods contain it, and its possible side effects.


Potassium benzoate is a white, odourless powder made by mixing benzoic acid and potassium salts under heat. Benzoic acid is a compound that occurs naturally in plants, animals and fermented products. Originally derived from the resin of benzoin from certain tree species, it is now mainly produced industrially.


Potassium salts are usually extracted from salt beds or certain minerals. Potassium benzoate is used as a preservative because it prevents the growth of bacteria, yeasts and especially moulds. It is therefore often added to food, beauty and skin care products to extend their shelf life.


Some beauty and skin care products that may contain this ingredient are shampoos, conditioners, face washes and moisturisers. Potassium benzoate is a preservative commonly found in food, beauty and skincare products. It helps to extend the shelf life by preventing the growth of bacteria, yeast and moulds.

Sodium Benzoate

Beverages: sodas, flavoured drinks and certain fruit and vegetable juices


Confectionery: sweets, chocolates and pastries


Condiments: processed sauces and salad dressings, plus pickles and olives


Spreads: certain margarines, jams and jellies


Processed meats and fish: salted or dried fish and seafood, and certain cold cuts


This preservative is also added to some vitamin and mineral supplements. It is also used as a substitute for sodium benzoate in foods that require a lower sodium content. You can tell if a food contains potassium benzoate by looking at the ingredients list.


Remember that foods made with potassium benzoate are often heavily processed and contain fewer nutrients and beneficial compounds than minimally processed foods. Therefore, it is best to limit your intake of these items - regardless of their potassium benzoate content. Many packaged and processed foods, including certain sweets, beverages, condiments and meats, contain potassium benzoate. You can look up this preservative on the ingredients list.

Is potassium benzoate harmful or safe?


Possible side effects


That said, this compound has potential side effects. When food or drinks containing both potassium benzoate and ascorbic acid (vitamin C) are exposed to heat or light, it may form the chemical benzene.


Foods containing benzene may cause hives or severe allergic reactions, especially in people who are prone to eczema, itchy skin or chronic nasal congestion or runny noses. Environmental exposure to benzene from factors such as motor vehicles, pollution or cigarette smoke has also been linked to an increased risk of cancer. However, more research is needed to determine whether ingesting small amounts poses the same health risks.


Studies have shown that young children exposed to benzene or benzoic compounds such as potassium benzoate may be at higher risk of developing attention deficit hyperactivity disorder (ADHD). Overall, further research is needed to determine the health effects of this preservative.
