Sodium Benzoate is a commonly used preservative in cosmetics and personal care products. It is the sodium salt of benzoic acid, a naturally occurring substance found in fruits like cranberries, plums, and apples. Sodium benzoate appears as a white, odorless crystalline powder or granules. Due to its antimicrobial properties, it helps prevent the growth of bacteria, fungi, and yeast, thus extending the shelf life of cosmetic products.

The chemical formula of Sodium Benzoate is C7H5NaO2.
Origin
Sodium benzoate is produced by the reaction of benzoic acid with sodium hydroxide. Benzoic acid is first dissolved in water, and then sodium hydroxide is added to form sodium benzoate and water. The resulting sodium benzoate is typically isolated through filtration or crystallization processes.
Safety profile
Sodium Benzoate is a safe ingredient when used within approved concentrations. It has been extensively studied and approved by regulatory bodies worldwide. However, a patch test is recommended. Sodium Benzoate is generally recognized as vegan since it is derived from a chemical reaction and not from animal sources. Additionally, sodium benzoate is also halal.
