Sodium Benzoate sold in use as a preservative for cosmetics, body shampoo lotoin.
Sodium benzoate is a salt of benzoic acid that is found naturally in cranberries, prunes, plums, apples, and other fruits. In its solid form it is a white, granular or crystalline powder. While benzyl alcohol is an organic alcohol with a hydroxyl group (-OH), the related compound benzoic acid has a carboxyl group (-COOH). Sodium benzoate is used in a wide variety of cosmetics and personal care products where it acts as a corrosion inhibitor, fragrance ingredient, and preservative.
As a preservative, sodium benzoate is primarily an anti-fungal agent but also has some effectiveness against bacteria. It is not a broad-spectrum preservative for cosmetic use and should be combined with other preservatives. Sodium benzoate is often combined with potassium sorbate in low pH products in order to benefit from the ingredients’ synergistic effects against yeast and mold. When combined with caffeine, it can have a sunscreen effect and provide UVB protection with antioxidant activity.
Protecting products from light and heat exposure also limits the potential for benzene formation. Manufacturers that follow safe practices can effectively prevent the formation of benzene in cosmetic products that also contain vitamin C. And for the most part, sodium benzoate is only used in formulas that do not contain significant levels of vitamin C. Overall, sodium benzoate is one of the most reliable ingredients on the market and very safe for consumers.
