Sodium Benzoate
SINOBIO
2916310000
Sodium Benzoate (sodium benzoate) is a commonly used food preservative
*Chemical formula: C₇H₅NaO₂
*Molecular weight: 144.11 g/mol
*CAS No.: 532-32-1
*Appearance: white crystalline powder or granule, odorless or slightly benzoin odor.
*Solubility: soluble in water (solubility at 20℃ is about 53 g/100 mL), slightly soluble in ethanol.
*Chemical properties:
-Aqueous solution is alkaline (pH about 8), because sodium benzoate is the sodium salt of benzoic acid, can be hydrolyzed in water to generate benzoic acid.
-Better antiseptic effect under acidic condition: when pH＜4.5, the proportion of free state of benzoic acid is high and the antimicrobial activity is strong; when pH increases, the antiseptic effect decreases.
| Product Name | Sodium benzoate |

The main advantage of Sodium Benzoate is that it is widely used as a preservative in food, medicine and other fields. The specific advantages are as follows:
Sodium benzoate can significantly inhibit the growth of mold, yeast and bacteria, and effectively extend the shelf life of food. In an acidic environment (such as pH 2.5-4.0), its preservative effect is best, and it is often used to preserve acidic foods such as beverages, jams, and preserves.
Sodium benzoate is stable in the air, not easily affected by environmental factors such as temperature and light, and can maintain its preservative effect for a long time. This feature makes it suitable for food and medicine that need to be stored or transported for a long time.
Compared with other preservatives, sodium benzoate has a lower production cost and is easy to obtain, which enables food manufacturers to meet preservative needs at a more economical cost and provide consumers with more affordable products.
Sodium benzoate is highly soluble in water, which is easy to disperse evenly in food processing to ensure the consistency of the preservative effect. At the same time, its properties of being slightly soluble in ethanol, soluble in glycerol and methanol also expand its application possibilities in different formulations.
* Food industry: widely used in the preservation and freshness of beverages, jams, condiments, canned foods and other foods.
* Pharmaceutical field: as a pharmaceutical preservative, it is used in preparations such as syrups and eye drops to prevent microbial contamination and ensure the quality of drugs.
* Industrial field: it plays a role in preserving and stabilizing in processes such as metal processing and rubber production, and can also be used for the preservation of industrial products such as coatings and plastics.
* Cosmetic field: it is used for the preservation of skin care products, shampoos and other products to extend the shelf life of products.
Sodium benzoate is considered relatively safe within the normal dosage range. After entering the human body, most of it will be converted into benzoic acid and combined with glycine or glucuronic acid, and finally excreted from the body through urine without accumulating in the body.
Packing: 25kg /bag. We provide customized package for different quantity.
