Overview

Bronopol (2-Bromo-2-nitropropane-1,3-diol) is a versatile, highly efficient bactericide and fungicide used across multiple industries including water treatment, personal care, paints, and oilfields. It offers strong efficacy against Gram-negative and Gram-positive bacteria, including problematic strains like sulfate-reducing bacteria. Known for its quick kill action, Bronopol is compatible with a wide range of formulations and performs well in acidic to neutral pH environments. It has a low toxicity profile and decomposes into non-persistent byproducts, reducing long-term environmental burden. Bronopol offers excellent stability, compatibility with other preservatives, and minimal environmental impact when used correctly. It performs well in both acidic and neutral pH environments and is often used in conjunction with other biocides for synergistic performance. Its low required dosage and fast action make it a reliable antimicrobial solution.
