Benzoic Acid

Benzoic acid is naturally found in gum benzoin but also occurs in honey and dairy products. Its salt, sodium benzoate, is water-soluable and is well-suited as a preservative in cosmetics and food. Both ingredients inhibits the growth of yeast and mold, as well as having slightly antimicrobial properties.
