Bronopol IP (2-bromo-2-nitropropane-1,3-diol) is a white, crystalline solid that is commonly used as a preservative in various industries, including cosmetics, personal care products, and industrial applications. It has antimicrobial properties that help to prevent the growth of bacteria, fungi, and other microorganisms that can degrade the quality of products.Bronopol IP works by releasing bromine atoms that react with microbial cell walls and disrupt their structure, preventing them from reproducing and eventually leading to their death. It is effective against a broad spectrum of microorganisms, including gram-positive and gram-negative bacteria, yeast, and molds.
