Properties and Usage:

Benzoic acid is a commonly used chemical raw material with excellent antiseptic properties. It is used in many fields such as food, cosmetics, pharmaceuticals and industrial production.

1. Food preservatives

Benzoic acid and its sodium salt (sodium benzoate) inhibit the growth of bacteria and fungi by reducing microbial activity and extend the shelf life of food. It is particularly suitable for acidic foods such as juices, condiments and sauces.

2. Cosmetics and pharmaceuticals

In cosmetics, benzoic acid is used as a preservative, which can effectively inhibit the growth of microorganisms and extend the shelf life of products.

In the pharmaceutical field, benzoic acid is used as an antibacterial agent for topical applications, such as drugs for the treatment of fungal infections, to help control infections and maintain drug efficacy.

3. Industrial applications

Benzoic acid is an important intermediate for many chemicals and is used to synthesize benzoic acid esters (plasticizers and fragrances), benzaldehyde (ingredients for dyes and fragrances) and benzoic acid chloride (intermediate for organic synthesis). In addition, benzoic acid is also used to make polymers and resins to improve the stability and heat resistance of these materials.

4. Plastics and synthetic resins

As an additive, benzoic acid improves the thermal stability and mechanical properties of plastics and synthetic resins, allowing them to maintain material properties at high temperatures or for long periods of time.

5. Solvents and coatings

Benzoic acid acts as a solvent and stabilizer in coatings and paints, enhancing the fluidity and coating properties of the product while providing better durability and gloss effects.
