White Particles Powder for Food Additive Sodium Benzoate CAS 532-32-1
1. Product Introduction
Sodium benzoate is an organic compound with the chemical formula C7H5NaO2. Sodium benzoate is a white particle or crystalline powder with no odor or slight resting aroma, a slightly sweet taste, and a astringent taste.
Sodium benzoate relative molecular weight is 144.12, stable in the air, easily soluble in water, and its aqueous solution has a pH value of 8, soluble in ethanol.
Benzoic acid and its salts are broad-spectrum antimicrobial agents, but their antibacterial effectiveness depends on the pH value of the food. As the acidity of the medium increases, its bactericidal and antibacterial effects increase, but in alkaline media, it loses its bactericidal and antibacterial effects. The optimal pH value for anti-corrosion is 2.5-4.0.
2. Product Specifications
Chemical formula: Sodium benzoate has the chemical formula C7H5NaO2 and is the sodium salt of benzoic acid.
Appearance: Sodium benzoate is a white, crystalline powder that is odorless and has a slightly bitter taste.
Solubility: Sodium benzoate is highly soluble in water, with a solubility of approximately 60 g per 100 mL of water at room temperature.

3. Product Application
Sodium benzoate is a preservative,It is most widely used in acidic foods such as salad dressings (i.e. acetic acid in vinegar),carbonated drinks (carbonic acid), jams and fruit juices (citric acid), pickles (acetic acid), condiments, and frozen yogurt toppings. It is also used as a preservative in cosmetics.
Sodium benzoate is a common type of food preservative and is the sodium salt of benzoic acid. Food manufacturers make sodium benzoate by synthesizing the compounds, sodium hydroxide and benzoic acid, together. In addition to its use as a food preservative, sodium benzoate has other roles in food production as well.
