Cetylpyridinium chloride is widely used as an antiseptic in various personal care products such as mouthwashes, throat lozenges, and nasal sprays. It effectively reduces bacteria and other microorganisms in the oral cavity, helping to prevent infections, bad breath, and gum diseases. In addition to oral care, it is also incorporated into some skin cleansers and wound disinfectants due to its antimicrobial properties. Furthermore, it finds application in certain over-the-counter medications for sore throats, providing relief by targeting the underlying bacterial causes. Its ability to act as a surfactant also makes it useful in some cleaning and sanitizing products for surfaces and fabrics.
