Sodium Benzoate (CAS 532-32-1, molecular formula C7H5NaO2) is a food grade preservative ingredient supplied by Guangzhou ZIO Chemical Co., Ltd. for acidic food and beverage systems where manufacturers need preservation support and effective shelf-life management. It is delivered as a white crystalline powder or granules in 25 kg bags or customized packaging, and is commonly considered for soft drinks, fruit beverages, sauces, dressings, jams, jellies, syrups, pickled foods and other appropriate processed foods. Standard material is commonly ≥99.0% assay, with the actual value confirmed on the current COA. ZIO supplies bulk quantities with specification-based sourcing for food manufacturers, distributors and private-label brands.
The product is supplied as a food grade preservative for suitable acidic food and beverage systems, supporting shelf-life management where permitted use levels and local regulations allow.
Assay and impurity control are important because preservative performance depends on both ingredient quality and the finished formulation. The exact value is stated on the current COA.
The dry crystalline format is practical for accurate weighing, storage and incorporation into existing production processes, whether batch or continuous.
Standard 25 kg bags support industrial production, while customized packaging can be arranged for distribution and private-label requirements.
Assay, moisture, acidity/alkalinity, heavy metals and other parameters are aligned to the applicable standard and confirmed before commercial use.

What is the CAS number and molecular formula of this product?
Sodium Benzoate is identified by CAS No. 532-32-1 and molecular formula C7H5NaO2. These are standard identification data used for documentation and procurement reference.
What assay or purity can be supplied?
Standard food grade material is commonly ≥99.0% assay. The actual assay, moisture, acidity/alkalinity and heavy-metal limits must be confirmed on the current COA for the batch you receive.
Which applications is sodium benzoate suitable for?
It is commonly considered for acidic food and beverage systems such as soft drinks, carbonated beverages, fruit beverages, juice drinks, sauces, dressings, jams, jellies, syrups, pickled foods and other processed foods. Final suitability depends on product composition, pH, permitted use level and destination-market regulations.
How is the product packaged and stored?
Standard packaging is a 25 kg bag, and customized packaging can be arranged. Store the material in a cool, dry and sealed condition before use.
Can it be used inside a complete premix?
Yes. Sodium Benzoate can be incorporated into complete premixes or used as an individual ingredient, depending on the customer's manufacturing system.
What documentation is available?
