Used primarily as a preservative and biocide in industrial water systems, paints, adhesives, and cosmetics due to its strong antimicrobial properties. It effectively controls the growth of bacteria, fungi, and algae, preventing spoilage and extending product shelf life. Commonly found in water-based formulations where microbial contamination is a concern. Its stability in a wide pH range and compatibility with various organic materials make it suitable for use in metalworking fluids and latex emulsions. Often used in combination with other biocides for enhanced performance.
