Used as a biocide and antimicrobial agent in industrial water treatment systems to control bacterial and fungal growth. Effective in cooling towers, paper mills, and metalworking fluids due to its ability to disrupt microbial cell membranes. Also utilized in cosmetic and personal care formulations as a preservative to prevent spoilage caused by microorganisms. Its long alkyl chain enhances lipid solubility, improving penetration into microbial cells. Stable over a wide pH range and compatible with various surfactants and emulsifiers, making it suitable for use in complex formulations.
