Bronopol

Bronopol (CAS 52-51-7), also known commercially as beta-Bromo-beta-nitrotrimethyleneglycol and 2-Nitro-2-bromo-1,3-propanediol, is a broad-spectrum antimicrobial active used primarily as a preservative and biocide.

Where is Bronopol used?

• Personal care and cosmetics: preservative in rinse-off and leave-on formulations including shampoos, lotions, and liquid soaps
• Industrial water treatment: suppresses bacterial populations
• Cooling towers and process water circuits: maintains system efficiency
• Oilfield and metalworking: prevents microbial-induced corrosion and spoilage in drilling fluids and cutting fluid emulsions
• Pulp, paper, and textile processing: controls slime-forming bacteria that degrade product quality and clog equipment
• It controls bacterial growth effectively at low concentrations.

Commercial specifications

• Technical grade for industrial applications; higher-purity grades meeting pharmaceutical and cosmetic manufacturing standards
• Packaging from kilogram-scale bags to bulk quantities
