--Product Introduction--
Sodium benzoate (C7H5NaO2) is a widely used preservative in the food, beverage, and pharmaceutical industries. It is the sodium salt of benzoic acid and appears as a white, odorless powder that is highly soluble in water. Sodium benzoate functions primarily by inhibiting the growth of microorganisms such as bacteria, yeasts, and molds, thereby extending the shelf life of products.
Sodium benzoate consists of a benzene ring with a carboxylate group attached, forming the sodium salt of benzoic acid
Unlike benzoic acid, which has limited solubility in water, sodium benzoate dissolves readily in water, making it easier to incorporate into aqueous solutions.
Sodium benzoate works best in acidic environments (pH 2.5 to 4.0). At higher pH levels, it converts back to benzoic acid, which is less soluble but more effective as a preservative due to its undissociated form.
Sodium benzoate is commonly produced by the neutralization of sodium hydroxide (NaOH) with benzoicacid (C6H5COOH) which is itself produced commercially by partial oxidation of toluene with oxygen.
The antiseptic mechanism of sodium benzoate is: benzoic acid is highly lipophilic and can easily pass through the cell membrane and enter the cell, interfering with the permeability of the cell membrane of microorganisms such as bacteria and mold, and inhibiting the absorption of amino acids by the cell membrane. The benzoic acid molecules that enter the cells inhibit the activity of the respiratory enzyme system of microbial cells, reducing the reaction rate catalyzed by phosphofructokinase in anaerobic respiration by 95%, thus playing an antiseptic role.
Main differences between Sodium benzoate & benzoic acid:
-
Application Forms:
- Sodium Benzoate: Due to its high water solubility, sodium benzoate is commonly used in liquid products like beverages, syrups, and sauces where it can easily dissolve and distribute throughout the product.
- Benzoic Acid: Benzoic acid, being less soluble in water, is more suitable for use in solid or semi-solid formulations, such as cosmetics, pharmaceutical creams, and certain food products that do not require immediate dissolution.
-
Preservation Mechanism:
- Sodium Benzoate: Once dissolved in an acidic solution, sodium benzoate dissociates into benzoate ions and sodium ions. The benzoate ions inhibit microbial growth by interfering with cell metabolism and disrupting cellular structures.
- Benzoic Acid: In its undissociated form, benzoic acid penetrates microbial cells more effectively than benzoate ions, acting directly on cell membranes and enzymes within the microorganism, thus providing stronger antimicrobial activity at lower pH levels.
