Description

Benzoic acid (CAS 65-85-0 ), also designated E210 in food and beverage applications, is a naturally occurring organic acid used commercially as a preservative and pH regulator. Its antimicrobial action against yeasts, moulds, and bacteria makes it a standard functional ingredient across food, personal care, and industrial formulations worldwide. In food and beverage production, E210 controls microbial growth in acidic products such as soft drinks, fruit juices, and condiments, where it is effective at low concentrations. Personal care formulators use it as a preservative and pH adjuster in rinse-off and leave-on products including shampoos, lotions, and liquid soaps for consumer safety. Coatings and resin manufacturers use benzoic acid as a chain-stopper and catalyst component in alkyd resin production, influencing molecular weight and drying performance. In pharmaceuticals, it functions as an intermediate in the synthesis of active ingredients and as a preservative in topical preparations for various medical applications. Benzoic acid is supplied as a white crystalline powder or flake. Commercially available grades include food-grade ( FCC ) and pharmaceutical-grade ( USP , BP , Ph.Eur. ). Technical-grade options are available for industrial applications. Packaging ranges from small drums to bulk quantities, supported by full compliance documentation for all sectors.
