Bronopol (2-Bromo-2-nitropropane-1,3-diol) is a high-performance antimicrobial agent used primarily as a preservative in water-based formulations. With broad-spectrum activity against bacteria, fungi, and yeast, Bronopol is widely utilized across personal care, cosmetics, pharmaceuticals, paints, adhesives, and water treatment industries.
Bronopol is especially effective in controlling Gram-negative bacteria, which are often resistant to many conventional preservatives. It is highly water-soluble, active at low concentrations, and compatible with a wide range of surfactants, emulsifiers, and other formulation ingredients. Its quick-acting nature makes it ideal for formulations prone to microbial contamination.
While popular in cosmetic applications like shampoos, lotions, and gels, it is also used industrially in cooling towers, paper mills, and oilfield injection waters due to its exceptional antibacterial properties.
