Description
Sodium benzoate, also known as sodium benzoate, is an organic compound. It is a white granule or crystalline powder with specific physical properties and is widely used in many fields, especially in food preservation. Sodium benzoate is an organic acid salt that can dissociate benzoate ions and sodium ions in water, so it is acidic. It is relatively stable at room temperature, but may decompose under high temperature, light or humid environment, resulting in a reduction in its antiseptic effect.

Application
1. Sodium benzoate is also an important preservative of acid type food. It transforms into effective form of benzoic acid during application. See benzoic acid for application range and dosage. In addition, it also can be used as fodder preservative.
2. Preservatives; antimicrobial agent.
3. Sodium benzoate agent is a very important preservative of acid type fodder. It transforms into effective form of benzoic acid during application. See benzoic acid for application range and dosage. In addition, it also can be used as food preservative.
4. Used in the research of pharmaceutical industry and plant genetic, also used as dye intermediates, fungicide and preservatives.
5. The product is used as food additive (preservative), fungicide in pharmaceutical industry, dye mordant, plasticizer in plastic industrial, and also used as organic synthetic intermediate of spices and others.
6. Sodium benzoate is used primarily as an antimicrobial preservative in cosmetics, foods, and pharmaceuticals. It is used in concentrations of 0.02–0.5% in oral medicines, 0.5% in parenteral products, and 0.1–0.5% in cosmetics. The usefulness of sodium benzoate as a preservative is limited by its effectiveness over a narrow pH range.
7. Sodium benzoate is used in preference to benzoic acid in some circumstances, owing to its greater solubility. However, in some applications it may impart an unpleasant flavor to a product. Sodium benzoate has also been used as a tablet lubricant at 2–5% w/w concentrations. Solutions of sodium benzoate have also been administered, orally or intravenously, in order to determine liver function.
Storge & Handling
Sodium Benzoate should be stored in a cool, dry place, away from direct sunlight and moisture. It should be kept in tightly sealed containers to prevent contamination and degradation.
