As the world’s largest manufacturer of benzoic acid, LANXESS delivers unmatched quality with PUROX® B Liquid, offering outstanding features such as low odor, no discoloration, low agglomeration, and ready biodegradability.

Used as a nature-identical preservative, PUROX® B is ideal for a wide range of applications in personal care, cosmetics, and household products. It is compatible with green label certifications including EU Ecolabel, COSMOS, and Nordic Swan, and shows enhanced preservation performance when used in synergy with multifunctionals and surfactants.

Beyond preservation, PUROX® B Liquid serves as a valuable intermediate and specialty additive. In alkyd resin synthesis, it functions as a building block and chain terminator, contributing to gloss, adhesion, hardness, and chemical resistance. In industrial formulations, it helps protect against corrosion and flash rust—critical in automotive coolants and architectural coatings. PUROX® B Liquid also enhances performance in high-strength HDPE filaments, thermoplastic elastomers, and synthetic polyester fibers, and even acts as a temporary plugging agent in downhole drilling for subterranean formations.
