Sodium Benzoate

Uses1. 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.

DescriptionSodium benzoate has the chemical formula NaC7H5O2; it is a widely used food preservative, with E number E211. It is the sodium salt of benzoic acid and exists in this form when dissolved in water. It can be produced by reacting sodium hydroxide with benzoic acid.

OccurrenceBenzoic acid occurs naturally in many plants and in animals. The salt is not found to occur naturally.

HistoryIn 1820, benzoic acid was discovered by German chemist Friedrich Wöhler through the oxidation of toluene. His research laid the groundwork for the eventual production of sodium benzoate. The process typically involves neutralizing benzoic acid with sodium hydroxide, creating sodium benzoate—a stable compound with excellent antibacterial and antifungal properties. Sodium benzoate was commercially introduced in the late 19th century. Its preservative qualities made it particularly valuable as food products began to be mass-produced and distributed. In 1908, sodium benzoate was recognized as a food preservative by the U.S. Food and Drug Administration (FDA). This allowed it to be used in various food products, including soft drinks, pickles, and sauces, to prevent spoilage and extend shelf life.

UsesSodium benzoate is a preservative. It is bacteriostatic and fungistatic under acidic conditions. It is most widely used in acidic foods such as salad dressings (vinegar), carbonated drinks (carbonic acid), jams and fruit juices (citric acid), pickles (vinegar), and condiments. It is also used as a preservative in medicines and cosmetics. As a food additive, sodium benzoate has the E number E211. It is also used in fireworks as a fuel in whistle mix, a powder that emits a whistling noise when compressed into a tube and ignited. The fuel is also one of the fastest burning rocket fuels and provides a lot of thrust and smoke. It does have its downsides: there is a high danger of explosion when the fuel is sharply compressed because of the fuel's sensitivity to impact.

UsesSodium Benzoate is a preservative that is the sodium salt of benzoic acid. it converts to benzoic acid, which is the active form. it has a solubility in water of 50 g in 100 ml at 25°c. sodium benzoate is 180 times as soluble in water at 25°c as is the parent acid. the optimum functionality occurs between ph 2.5 and 4.0 and it is not recom- mended above ph 4.5. it is active against yeasts and bacteria. it is used in acidic foods such as fruit juices, jams, relishes, and bever- ages. its use level ranges from 0.03 to 0.10%.

Usessodium benzoate is a non-toxic, organic salt preservative that is particularly effective against yeast, with some activity against molds and bacteria. It is generally used in concentrations of 0.1 to 0.2 percent.

UsesVasodilator

UsesA benzene compound used as a synthetic reagent.

UsesAntimicrobial agent, flavoring agent and adjuvant in food; not to exceed a maximum level of 0.1% in food (21 CFR, 184.1733, 582.3733). Antifungal and bacteriostatic preservative in pharmaceuticals at concentrations of ~0.1%. Clinical reagent (bilirubin assay).

General DescriptionSodium benzoate is a sodium salt of benzoic acid, that is freely soluble in water compared to benzoic acid. It is generally used as an antimicrobial preservative in cosmetics, food, and pharmaceuticals.Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.

DefinitionChEBI: An organic sodium salt resulting from the replacement of the proton from the carboxy group of benzoic acid by a sodium ion.

Definitionsodium benzoate: An either colourlesscrystalline or white amorphouspowder, C6H5COONa, soluble inwater and slightly soluble in ethanol.It is made by the reaction of sodiumhydroxide with benzoic acid and isused in the dyestuffs industry and asa food preservative. It was formerlyused as an antiseptic.
