Used as a biocide in water treatment systems, particularly in cooling towers and industrial water circuits, to control microbial growth including bacteria, algae, and fungi. It releases active chlorine slowly, providing sustained disinfection with reduced risk of rapid degradation compared to other chlorinated compounds. Also employed in metalworking fluids to prevent spoilage and odor caused by microbial contamination. Its stability under varying pH and temperature conditions makes it suitable for use in household and industrial cleaning products. Additionally, it finds application in personal care products as a preservative due to its antimicrobial properties and low irritation potential.
