Benzoic acid and its esters are found in essential oils (cloves, tioan and Peruvian balms, benzoic rubber).
Benzoic acid and its salts have high bactericidal and bacteriostatic activity.
Because of these properties, as well as non -toxicity, benzoic acid is used as a preservative in the food industry (adding 0.1% acid to sauces, cucumbers, fruit juices, jams, minced meat, etc.),
This is an antiseptic in medicine (especially in dermatology), in the production of perfumery and cosmetics.
