Product Overview

Zinc Benzoate is an organic zinc salt derived from benzoic acid, appearing as a fine white to off-white powder. It is widely recognized for its excellent antimicrobial properties, thermal stability, and compatibility with a wide range of industrial formulations.

Due to its dual functionality—providing both zinc ions and benzoate groups—it plays an important role in preservation systems, polymer stabilization, and specialty chemical applications.
