Category: Sodium benzoate solubility in water

Sodium benzoate, sometimes also called benzoate of soda, is the sodium salt of benzoic acid. It is an aromatic compound denoted by the chemical formula C 7 H 5 NaO 2 with a molecular weight of Sodium benzoate can be made by chemically combining sodium hydroxide with benzoic acid. In its refined form, sodium benzoate is a white, odorless compound that has a sweet, astringent taste, and is soluble in water.

Sodium benzoate has antimicrobial characteristics, and is typically used as a preservative in food products. Sodium benzoate has a density of 1. Sodium benzoate is supplied as a white powder or flake. During use, it is mixed dry in bulk liquids where it promptly dissolves.

Approximately 1. In contrast, benzoic acid has a significantly lower water solubility profile. When placed in water, sodium benzoate dissociates to form sodium ions and benzoic acid ions. Benzoic acid is a weak organic acid that contains a carboxyl groupand occurs naturally in some foods, including cranberries, prunes, cinnamon, and cloves.

It is also formed by most vertebrates during metabolism.

Sodium benzoate is an antimicrobial active against most yeast and bacterial strains. It works by dissociating in the system and producing benzoic acid. Benzoic acid is highly toxic to microbes, however, it is less effective against molds. Overall, it is more effective as the pH of a system is reduced with the optimal functional range between pH 2. The antimicrobial effect is also enhanced by the presence of sodium chloride. There are three methods for the commercial preparation of sodium benzoate.

In one method, naphthalene is oxidized with vanadium pentoxide to give phthalic anhydride.

This is decarboxylated to yield benzoic acid. In a second method, toluene is mixed with nitric acid and oxidized to produce benzoic acid. In a third method, benzotrichloride is hydrolyzed and then treated with a mineral acid to give benzoic acid.

Benzotrichloride is formed by the reaction of chlorine and toluene. In all cases, the benzoic acid is further refined to produce sodium benzoate. One way this is done is by dissolving the acid in a sodium hydroxide -solution.

The resulting chemical reaction produces sodium benzoate and water. The crystals are isolated by evaporating off the water. Some toxicity testing has shown sodium benzoate to be poisonous at certain concentrations. Acid — A substance that produces hydrogen ions when placed in an aqueous solution.

Antimicrobial — A material that inhibits the growth of microorganisms that cause food to spoil. Oxidation — A process by which a compound loses electrons. Preservative — A compound added to food products to ensure they do not spoil. Solubility — The amount of a substance that will dissolve in a solution at a given temperature. Department of Agriculture USDA has found that in small doses and mixed with food, sodium benzoate is not deleterious to health.Sodium benzoate is the sodium salt of Benzoic Acid used as a preservative, also in a wide range of cosmetic product types.

It is used as a preservative in cosmetics and personal care product formulas as a fragrance ingredient, masking ingredient, anti-corrosive agent, and most frequently, as a preservative. Sodium benzoate is the inactive salt of benzoic acid which is soluble in water. At low pH levels in water, sodium benzoate converts to benzoic acidthe active form of the compound.

The activity of benzoic acid is very pH dependent, showing low activity above pH 6 and most active at pH3. Sodium benzoate is generally recognized as safe in foods according to the U. Food and Drug Administration 1. As a preservative in cosmetic formulations, it is primarily an anti-fungal agent that prevents fungi from developing in products and formulas and changing their composition. It is less effective against bacteria. As Sodium benzoate is not a broad spectrum preservative for cosmetic, it should be combined with other preservatives.

Potassium sorbate is often combined with Sodium benzoate in low pH products to provide a synergistic preservative effect against yeast and mold. Sodium benzoate is considered to be a low-risk ingredient for skincare use and safe to use in skincare 3. As Sodium benzoate is not a broad spectrum preservative for cosmetic, it should be combined with other preservativessuch as potassium sorbate.

Sodium benzoate is considered to be a low-risk ingredient for skincare use and safe to use in skincare. Sodium benzoate is a substance which has the chemical formula NaC 7 H 5 O 2. It is a widely used food preservativewith an E number of E 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. Sodium benzoate is produced by the neutralization of benzoic acid[3] which is itself produced commercially by partial oxidation of toluene with oxygen.

While sodium benzoate does not occur naturally, benzoic acid and its esters are found in many foods. Other sources include seafood, such as prawns, and dairy products like milk, cheese, and yogurt. Sodium benzoate is a preservativewith the E number E It is most widely used in acidic foods such as salad dressings i.

The mechanism starts with the absorption of benzoic acid into the cell. If the intracellular pH falls to 5 or lower, the anaerobic fermentation of glucose through phosphofructokinase decreases sharply, [20] which inhibits the growth and survival of microorganisms that cause food spoilage. Cats have a significantly lower tolerance against benzoic acid and its salts than rats and mice.

The human body rapidly clears sodium benzoate by combining it with glycine to form hippuric acid which is then excreted. In combination with ascorbic acid vitamin C, Esodium benzoate and potassium benzoate may form benzene. Inthe Food and Drug Administration tested beverages available in the United States that contained both ascorbic acid and benzoate. Four had benzene levels that were above the 5 ppb Maximum Contaminant Level set by the Environmental Protection Agency for drinking water.

Research published in for the UK's Food Standards Agency FSA suggests that certain artificial colorswhen paired with sodium benzoate, may be linked to hyperactive behavior. The results were inconsistent regarding sodium benzoate, so the FSA recommended further study. Many other influences are at work but this at least is one a child can avoid.
