For Research and Development scientists and product formulators, understanding the scientific underpinnings of the ingredients they use is crucial for innovation and product success. Sodium Benzoate (CAS 532-32-1) is a widely utilized chemical compound with well-defined properties that make it an indispensable preservative in many industries. As a dedicated supplier, we aim to provide insight into the science behind this versatile compound, aiding your formulation efforts.

Chemical Properties and Mechanism of Action

Sodium Benzoate is the sodium salt of benzoic acid, with the chemical formula C7H5NaO2. It typically appears as a white crystalline powder or granules and is readily soluble in water. The key to its preservative function lies in its ability to convert into benzoic acid (C6H5COOH) in acidic conditions (pH below 4.5). Benzoic acid is the active antimicrobial agent. Once inside microbial cells, benzoic acid becomes undissociated and can penetrate cell membranes. Inside the cell, where the pH is typically neutral, the benzoic acid dissociates, releasing hydrogen ions. This process can disrupt cellular pH homeostasis and enzyme activity, particularly inhibiting anaerobic fermentation of glucose, thereby preventing microbial growth. This mechanism makes it highly effective for food preservative applications in products like sodas, pickles, and fruit juices.

Applications and Formulation Considerations

R&D scientists often need to consider the optimal pH range for Sodium Benzoate's effectiveness. While it is effective in acidic environments, its antimicrobial activity is reduced at higher pH levels. Formulators also need to be aware of its solubility characteristics and potential interactions with other ingredients. Beyond food and beverages, Sodium Benzoate is valued in the pharmaceutical industry for its role in treating urea cycle disorders and as an excipient in drug formulations. In cosmetics, it serves as a preservative to prevent spoilage. For those looking to buy Sodium Benzoate food preservative, understanding these application nuances will lead to more effective product development. We provide detailed specifications to support your formulation work.

Sourcing High-Quality Sodium Benzoate

As a leading Sodium Benzoate manufacturer in China, we ensure our product meets stringent quality standards, including USP, BP, and FCC IV. This means that when you source from us, you are receiving a product that has undergone rigorous testing for purity, efficacy, and safety. This commitment is particularly important for pharmaceutical and food applications where compliance is critical. If you are searching for a USP Sodium Benzoate supplier, our adherence to these pharmacopeial standards makes us an ideal partner. We facilitate the procurement of this essential chemical, offering competitive food grade Sodium Benzoate price points for bulk purchases.

Ensuring Product Stability and Safety

The shelf life of Sodium Benzoate itself is typically around two years when stored correctly. It's important for formulators to consider its potential reaction with ascorbic acid (Vitamin C) in certain conditions, which can form small amounts of benzene. Modern manufacturing practices and careful formulation can mitigate these risks. By choosing a reputable manufacturer like us, you can trust the quality and consistency of the product you receive, allowing you to focus on perfecting your formulations. We are equipped to handle requests to order Sodium Benzoate bulk, ensuring prompt delivery and consistent quality.
