Overview of Benzoic Acid

Benzoic Acid is a carboxylic acid that smells good and is found in nature. Its molecular formula is C₇H₆O₂ (C₆H₅COOH). It is a white powder that smells faintly sweet, like cherries or sweet almonds. It can be found in nature in things like benzoin resin and fruits like cranberries and blueberries, but most of the time it is made by oxidising toluene. In cosmetics and perfumes, it is valued for its ability to keep products fresh, balance pH, and add subtle sweet-balsamic notes to enhance scent.

Applications of Benzoic Acid

Preservative & Antimicrobial Agent

Because it works well against yeasts, moulds, and some bacteria, benzoic acid is a common preservative in cosmetics, personal care products, and some foods. It helps food last longer by inhibiting microbial growth, and it is often combined with other preservatives like Phenoxyethanol or Benzyl Alcohol to enhance their effectiveness.

Fragrance Ingredient & Aroma Modifier

It contributes to fragrance bases by adding warm and slightly sweet balsamic nuances, often found naturally in benzoin resins. Benzoic acid enhances the aroma complexity and acts as a pH adjuster within formulations to maintain olfactory and product stability.​

pH Adjuster & Product Stabilizer

Benzoic acid helps keep cosmetic ingredients stable and prevents them from breaking down by controlling the pH levels in formulations. This makes sure that the products work and are safe.

Safety & Handling Guidelines

• Benzoic Acid should be handled with gloves and protective equipment to avoid skin and eye irritation.
• It can cause mild redness or inflammation upon direct contact and respiratory discomfort if inhaled in powdered form.
• It is combustible, so keep away from heat, sparks, and open flames. Store in tightly sealed containers in a cool, dry, and well-ventilated area, away from oxidising agents and acids.​
• Spills should be contained and cleaned with inert absorbents, then disposed of in accordance with local environmental regulations. Wash hands thoroughly after handling, and avoid ingestion or breathing dust/fumes.​
• Consult the Material Safety Data Sheet (MSDS) for complete toxicological, safety, and environmental guidelines before industrial-scale use.
