Factory Supply Benzoic Acid

Benzoic acid, as an important organic compound, has a wide and diverse range of application fields.  

  Application：

•   Food Industry

High-Efficiency Preservative  

Antiseptic Mechanism Benzoic acid and its sodium salts (such as sodium benzoate) exhibit the best antibacterial effects in an acidic environment with a pH of 2.5-4.0. They can effectively inhibit molds, yeasts, and some bacteria, but have a weaker effect on acid-producing bacteria. The molecular state is more active than the ionic state, so it needs to be used in acidic foods (such as beverages, soy sauce, and jams). 

Application Scenarios Widely used in soy sauce, vinegar, pickled vegetables, seasonings, and soft drinks, it is often compounded with p-hydroxybenzoates to enhance the effect. When using, it needs to be converted into sodium salt through sodium carbonate to improve water solubility, or added after dissolving in ethanol. 

•  Pharmaceutical and Daily Chemical Fields

Drug Synthesis and Treatment 

As an intermediate, it participates in the synthesis of antibacterial drugs. For example, topical ointments (benzoic acid salicylic acid ointment) are used to treat fungal infections such as tinea corporis and tinea pedis. Its derivatives (such as bromobenzoic acid) can be used as adhesives for electrophotographic materials and dye intermediates. 

Cosmetics and Daily Chemicals 

Benzoates are used as preservatives and acidity regulators in cosmetics to extend product stability. 

•  Core Raw Material in Chemical Production 

Plasticizer Synthesis 

Benzoic acid reacts with polyols (such as diethylene glycol) to produce plasticizers such as diethylene glycol dibenzoate (DEDB), which are used in plastic and rubber products to improve flexibility. 

Fragrances and Dyes

It is used in esterification reactions to prepare edible flavors with fruity aromas (lemon, berry), or as a fixative for tobacco flavors. It participates in the dyeing process as a mordant and is used in the synthesis of dye intermediates.
