Primarily used as a preservative and antimicrobial agent in personal care products, such as shampoos, conditioners, and cosmetics, to prevent microbial growth and extend shelf life. It is effective against a broad spectrum of bacteria and fungi, making it suitable for water-based formulations. Additionally, it finds application in industrial settings as a biocide in water treatment systems, cooling towers, and in the production of polymers and plastics to control microbial contamination and enhance resistance to biodegradation. Its stability in various pH ranges and compatibility with other ingredients make it a versatile choice in formulations requiring microbial protection. However, its use should consider safety and regulatory requirements due to potential health and environmental impacts.
