FAQ

What is Sodium Benzoate (CAS: 532-32-1)?

Sodium benzoate (CAS: 532-32-1) is a chemical compound used as a preservative. Its chemical formula is C7H5NaO2. It appears as a white crystalline powder, soluble in water, and has antimicrobial properties. Commonly used in food and pharmaceuticals, it inhibits spoilage by preventing microbial growth. Sodium benzoate is the sodium salt of benzoic acid, widely recognized for its stability and effectiveness in acidic environments.

What are the main uses of Sodium Benzoate (CAS: 532-32-1)?

Sodium benzoate (CAS: 532-32-1) is primarily used as a food preservative to extend shelf life. It also serves in pharmaceuticals as an antiseptic and in industrial settings for synthetic polymer production. In research, it acts as a pH regulator and buffer. Additionally, it is used in cosmetics and personal care products. Its versatility stems from its ability to inhibit microbial growth in acidic conditions, making it valuable across multiple sectors.

Is Sodium Benzoate (CAS: 532-32-1) safe?

Sodium benzoate (CAS: 532-32-1) is generally recognized as safe (GRAS) by the FDA for food use. However, high concentrations may cause health risks, such as allergic reactions or toxicity. Proper handling, like avoiding inhalation and skin contact, is essential. It meets safety standards for industrial and pharmaceutical applications but should be used cautiously in sensitive populations. Always follow safety guidelines and regulations.

How should Sodium Benzoate (CAS: 532-32-1) be stored?

Sodium benzoate (CAS: 532-32-1) should be stored in a cool, dry place, away from moisture and light. Keep it in airtight containers to maintain stability and prevent degradation. Storage temperature should be below 25°C, with humidity levels below 60%. Avoid exposure to strong acids or bases to preserve its chemical integrity and ensure long shelf life.
