Sodium Benzoate (CAS 532-32-1) is a critical multifunctional chemical additive and a core preservative in modern manufacturing, renowned for its exceptional microbial inhibition capability and broad formulation compatibility. As a stable sodium salt of benzoic acid, it acts as a high-efficiency anti-spoilage agent, effectively suppressing the growth of harmful microorganisms while maintaining the intrinsic properties of target products, thus meeting rigorous quality and safety requirements across various industries.
Widely utilized in global markets, it is primarily applied in the production of food and beverages (e.g., carbonated drinks, processed meats, pickles, and baked goods), pharmaceuticals (liquid medications, topical creams, and oral suspensions), personal care products (skincare lotions, shampoos, and cosmetics), as well as industrial water treatment and animal feed formulations. These applications rely on its preservative and pH-regulating functions to extend product shelf life, enhance formulation stability, and ensure end-product safety.
Our Sodium Benzoate product offers multiple grade options (food, pharmaceutical, and industrial grades) to match diverse application scenarios, featuring strict quality control systems that ensure high purity (≥99.5%) and ultra-low heavy metal content. We guarantee steady bulk supply, complete regulatory documentation (including MSDS and global certification), and customized logistics solutions for safe transportation. Additionally, our professional technical team provides personalized support—such as formulation compatibility testing and dosage optimization guidance—to help you improve production efficiency and ensure compliance with regional safety standards.
