Sodium Benzoate: Uses, Benefits, and Safety in Everyday Products
Sodium Benzoate is one of the most widely used preservatives across food, beverages, cosmetics, and pharmaceuticals. Recognized for its effectiveness in preventing microbial growth, this ingredient plays a crucial role in extending shelf life while maintaining product quality. Let’s take a closer look at what Sodium Benzoate is, its applications, and why it continues to be a trusted choice in multiple industries.
What is Sodium Benzoate?
Sodium Benzoate is the sodium salt of benzoic acid. It is a white, crystalline powder that dissolves easily in water, making it an ideal preservative for liquid-based products.
