Used as a cationic surfactant and antiseptic agent, particularly in topical disinfectants and personal care products. It exhibits antimicrobial activity against a range of bacteria and fungi, making it suitable for use in skin cleansers, wound treatments, and oral hygiene products. Its surfactant properties help in reducing surface tension, enhancing cleaning and emulsifying effects. Also employed in some laboratory applications for cell membrane disruption and nucleic acid purification due to its ability to lyse cells and precipitate biomolecules.
