What Is Sodium Benzoate?
Sodium benzoate is used as a preservative used in food, beverages, and personal care items. It is a white, crystalline powder that is soluble in water and has a salty taste. Sodium benzoate is a sodium salt of benzoic acid, which is naturally occurring in some fruits and vegetables (1).
As a preservative, the use of sodium benzoate is safe and effective, which helps to extend their shelf life. Sodium benzoate is often used in combination with other preservatives, like potassium sorbate, to provide additional protection against spoilage (2).
Sodium benzoate is also used in cosmetic products and personal care products, including beauty and hair products. However, the amount of sodium benzoate present in a product can vary, but it is typically used in very small quantities as a preservative. In these products, it helps to preserve the product and prevent the growth of microorganisms. It is generally recognized as safe (GRAS) for use in cosmetics and personal care products at certain concentrations.
Is Sodium Benzoate Safe To Use?
Sodium benzoate is often considered safe for use in cosmetics and personal care products at certain concentrations. It has been approved for use as a food preservative by regulatory agencies around the world, including the U.S. Food and Drug Administration (FDA) (3).
However, some people may be sensitive to sodium benzoate and may experience irritation or other side effects when using natural products that contain it. If you have sensitive skin or are prone to allergies, you may want to choose beauty products that do not contain sodium benzoate or other synthetic preservatives.
However, it is important to note that the formation of benzene in cosmetic products containing both sodium benzoate combined with high levels of vitamin C is rare and typically occurs only under certain conditions. Manufacturers that follow safe practices and use low concentrations of sodium benzoate can effectively prevent the formation of benzene in their productsHowever, it is important to note that the formation of benzene in cosmetic products containing both sodium benzoate combined with high levels of vitamin C is rare and typically occurs only under certain conditions. Manufacturers that follow safe practices and use low concentrations of sodium benzoate can effectively prevent the formation of benzene in their products (5).
In addition, the levels of benzene that may be present in products containing sodium benzoate and vitamin C are typically much lower than the safe exposure limits established by regulatory agencies. As a result, the risks associated with benzene in these products are considered to be low.
Sodium benzoate in skincare, beauty, and hair products, which follow safe practices of a combination of sodium benzoate and other ingredients are the best choices.
How To Use Sodium Benzoate in Homemade Hair Care Recipes
Sodium benzoate is a food-grade preservative that can be used in homemade hair care recipes, but it is important to use it with caution. Here are some tips for using sodium benzoate in homemade hair care recipes:

- Combine with other preservatives: Sodium benzoate is most effective when combined with other preservatives, such as phenoxyethanol or potassium sorbate.
- Do a patch test: Before using any new product, including those made with sodium benzoate, it's always a good idea to do a patch test to make sure you're not allergic or sensitive to it.
- Store in a cool and dry place: Homemade hair care products containing sodium benzoate should be stored in a cool and dry place to prevent spoilage and extend the shelf life.
- Consult a professional: If you're unsure about using sodium benzoate in your homemade hair care recipes, it's best to consult a professional for guidance.

- Preservative: Sodium benzoate helps to extend the shelf life of your products. This means that products containing sodium benzoate are less likely to spoil or go bad, making them more convenient and cost-effective for consumers.
- Safe and non-toxic: Sodium benzoate is generally considered safe in cosmetics, and haircare products and has a low toxicity level. It is approved for use by the Food and Drug Administration (FDA) as a food preservative and is considered safe for use in cosmetics and personal care products.
- Non-irritating: Sodium benzoate is generally non-irritating and does not cause skin irritation or allergic reactions in most people. This makes it suitable for use on sensitive skin, as well as in products that are intended for use on large areas of the body.
Overall, sodium benzoate is a useful and effective ingredient in skin care products. It helps to prevent the growth of bacteria and other microorganisms, which can cause skin problems and make products spoil, and it is generally safe and non-irritating.
Side Effects of Sodium Benzoate
Sodium benzoate is generally considered safe for use in cosmetics and personal care products. It has a low toxicity level and is not known to cause irritation or allergic reactions in most people. However, there are a few potential side effects of sodium benzoate that you should be aware of:
- Benzene formation: Studies suggest that sodium benzoate may be linked to the formation of benzene when combined with vitamin C (ascorbic acid) at high concentrations. It is important for manufacturers to follow safe practices and use low concentrations of sodium benzoate in their products to effectively prevent the formation of benzene, which would inevitably increase the effectiveness of sodium benzoate.
- Allergic reactions: Although rare, it is possible for individuals to have an allergic reaction to high levels of sodium benzoate. Symptoms of an allergic reaction may include skin irritation, redness, itching, and swelling. If you experience any of these symptoms after using products with sodium benzoate, stop using the product and consult a healthcare professional.
