Product Overview
Benzoic Acid (E210) is a widely used food preservative. It shows strong antimicrobial activity against molds and yeasts, performing best in acidic environments. Approved by global food safety authorities, it is commonly added to acidic food and beverage products to extend shelf life. It can also be incorporated in cosmetic formulations and animal feed premixes.
Characteristics
1.White crystalline powder or flakes
2.Stable under dry and cool storage
3Optimal antimicrobial performance at pH 2.5–4.0
4.Slightly soluble in water, soluble in ethanol
5.Compliant with international food additive standards
Main Functions
1.Preservative: inhibits the growth of molds, yeasts and spoilage bacteria in acidic systems, to prevent food spoilage and prolong shelf life.
2.Acidulant: lowers the pH of formulations, helping to maintain acidic conditions and support preservative efficiency.
Applications
1.Food & Beverage: carbonated drinks, fruit juices, jams, pickled vegetables, sauces, fruit syrups.
2.Cosmetics & personal care: preservative and mild acid regulator for acidic cosmetic formulations.
3.Animal feed: used in acidic premixes, subject to local regulations.

Similarity |
Main Difference |
Typical Focus |
| Benzoic Acid |
Antimicrobial, works in acidic environment |
Free acid form, lower water solubility, stronger antibacterial activity |
Acidic food, beverage, alcohol drinks |
| Sodium Benzoate |
Antimicrobial, works in acidic environment |
Sodium salt, high water solubility, easy to dissolve in liquid |
Beverages, sauces requiring good solubility |
