Widely used as an antimicrobial preservative in pharmaceutical and cosmetic formulations. Effective against bacteria and fungi, making it suitable for topical products like creams, ointments, and oral care solutions. Commonly found in throat lozenges and antiseptic mouthwashes due to its ability to reduce microbial load in the oral cavity. Its stability and low irritation potential enhance its suitability for use in products intended for prolonged or repeated human contact.
