Used primarily as an antiseptic and disinfectant, this compound is effective against a broad spectrum of bacteria, fungi, and some viruses. It is commonly found in throat lozenges and oral hygiene products due to its ability to target infections in the mouth and throat. Its positive charge allows it to bind effectively to negatively charged microbial cell membranes, disrupting their function and leading to cell death. It is also used in topical formulations for skin and mucous membrane infections. Due to its local action and low systemic absorption, it is considered safe for use in mild to moderate infections of the oral cavity and upper respiratory tract.
