Sodium Benzoate  (CAS: 532-32-1) 

Sodium benzoate is one of the flagship toluene oxidation series products manufactured by Biet Co., Ltd. It is primarily used as an ‌acidic preservative‌ and ‌chemical intermediate‌, with main applications spanning the food, pharmaceutical, daily chemical and industrial anti-corrosion fields. Leveraging its mild and highly effective bacteriostatic properties, it serves as a safe and reliable core raw material in multi-industry scenarios, and its bacteriostatic performance is highly dependent on an acidic environment (optimal pH range: 2.5-4.0). Its core application directions are as follows:

Food Sector

As a widely used food-grade preservative and antimicrobial agent in the industry, sodium benzoate can specifically inhibit the reproduction of yeasts, molds and bacteria. It is highly compatible with the preservation requirements of various acidic foods such as carbonated drinks, soy sauce, pastes, candied fruits, pickled vegetables, jams and fruit & vegetable juices. When added within the compliant dosage range, it will not damage the original flavor and nutritional structure of food, can significantly extend the shelf life of products, prevent spoilage and deterioration during storage and transportation, and the whole process meets the safety control standards of the food industry.

Pharmaceutical Sector

In pharmaceutical production scenarios, sodium benzoate can not only be added as a compliant preservative component to oral liquids, syrups and external preparations to inhibit the growth of microorganisms in the liquid medicine, ensure the quality stability of drugs within their validity period and meet pharmaceutical-grade safety requirements, but also act as an intermediate to participate in the synthesis of some active pharmaceutical components. It has mature application scenarios in the fields of pharmaceutical excipients and organic synthesis.

Personal Care & Daily Chemicals

It is a commonly used mild preservative ingredient in daily chemical products such as shampoos, body washes, toothpastes and skin care products. It can effectively prevent the growth of microorganisms in paste and liquid products, avoid contamination and deterioration of products during long-term use. Meanwhile, it can also assist in stabilizing the fragrance components in perfume products, slow down the volatilization rate of fragrances, make the aroma of perfumes and soap-based fragrances last longer, and maintain the stable olfactory performance of products.

Other Application Sectors

• ‌Tobacco & Feed Industry‌: Used as an antimicrobial auxiliary, it can effectively inhibit the reproduction of harmful microorganisms in raw materials, extend the storage period of tobacco and feed products, and prevent mildew and deterioration of products.
• ‌Industrial Metal Protection‌: It can be used as the core component of anti-rust fluids for automotive cooling systems, and is also compatible with various metal anti-corrosion scenarios. It effectively inhibits the oxidation and corrosion reaction of metal parts, reduces the rust risk inside cooling systems and industrial metal equipment, and greatly extends the service life of the equipment.
• ‌Coatings & Printing and Dyeing Industry‌: Added as an auxiliary agent to coatings, latex pastes and printing and dyeing processing systems, it can not only prevent mildew in the production system, but also assist in optimizing the overall stability performance of products, so as to guarantee the final quality of finished coatings and printing & dyeing products.
