Product overview
Bronopol is a broad-spectrum biocide and preservative, supplied by Kranti Chemicals as a white to off-white crystalline powder. It is widely used to control bacterial, yeast and fungal growth across industrial and consumer applications, valued for its fast kill-rate, water solubility and broad formulation compatibility.
Its high water solubility and rapid kill rate make it a preferred slug-dose or continuous-feed biocide for cooling towers and oilfield injection water, while its established regulatory profile supports its use as an in-can preservative across metalworking fluids, paints and coatings, and personal-care formulations.
