2-Bromo-2-Nitropropane-1,3-Diol (Formaldehyde Releaser)
What is 2-Bromo-2-Nitropropane-1,3-Diol (Formaldehyde Releaser)?
2-Bromo-2-Nitropropane-1,3-diol, commonly called bronopol, is a synthetic organic compound designed for use in cosmetics. Developed as a broad-spectrum antimicrobial agent, it appears as a white crystalline powder soluble in water. In skincare formulations, particularly those with high water content like lotions, creams, and shampoos, it functions by slowly decomposing to release formaldehyde. This active form disrupts microbial cell processes, inhibiting the growth of bacteria, yeasts, and molds. Its efficacy stems from this controlled release mechanism, allowing low concentrations to provide long-lasting protection against contamination. Typically incorporated into both rinse-off and leave-on products, it helps ensure product stability without altering texture or appearance.
