Introduction to Sodium Benzoate

Share:

October 20, 2025

Sodium Benzoate is a white granular or crystalline powder, odorless or with a slight benzoin odor and a slightly sweet taste. Sodium Benzoate is relative molecular mass is 144.12. Sodium Benzoate is the sodium salt of benzoic acid and an acidic preservative. Sodium Benzoate is most effective in acidic environments. Sodium Benzoate is a commonly used food preservative, preventing spoilage and extending shelf life. The optimal pH for Sodium Benzoate preservation is 2.5-4.0.

Sodium Benzoate, a common food additive, pharmaceutical intermediate, and chemical raw material, is widely used worldwide. Sales of Sodium Benzoate in China have shown significant growth over the past few years.

According to data, Sodium Benzoate sales in China increased from approximately 116,400 tons to approximately 160,600 tons from 2017 to 2022, with a compound annual growth rate of 6.6%. Sales revenue from sodium benzoate increased from approximately 942 million yuan to approximately 1.541 billion yuan, with a compound annual growth rate of 10.4%. This indicates that market demand for Sodium Benzoate is expanding with the development of the domestic economy and increasing consumer demand.

The market demand for Sodium Benzoate is also expanding, and Sodium Benzoate offers the following advantages:

Excellent antiseptic properties

Sodium Benzoate inhibits bacterial and fungal growth by disrupting microbial cell membranes, and is particularly effective in neutral or slightly acidic environments. Sodium Benzoate is commonly used in foods such as carbonated beverages, juices, and sauces, typically at a dosage of no more than 0.1%, effectively extending shelf life.

PH Adjustment

As a weak acid salt, Sodium Benzoate can maintain pH stability in pharmaceuticals and cosmetics.

Medical Adjunctive Therapy

In the medical field, Sodium Benzoate can be used as a uric acid binder to treat hereditary hyperuricemia, lowering blood ammonia levels by promoting the excretion of water-soluble benzoyluric acid. Furthermore, Sodium Benzoate is used in the preparation of gargles for conditions such as stomatitis and pharyngitis.

Multiple Applications

Besides food and pharmaceuticals, Sodium Benzoate is also used as a preservative in industrial products such as latex and paint, and as a preservative in cosmetics.

In the future, with growing market demand and increasing environmental protection requirements, the Sodium Benzoate industry will face even more intense market competition. Companies need to continuously strengthen technological innovation and quality improvement of Sodium Benzoate to adapt to market changes and meet user needs.
