Biguanides are a class of antimicrobial and antifungal agents widely used in the textile industry, particularly for fabric treatments that enhance their water repellency and wrinkle resistance. These compounds also find applications in personal care products due to their mild antibacterial properties. For instance, biguanides are commonly incorporated into bandages and wound dressings, providing a protective barrier against bacterial infection. Additionally, they are utilized as preservatives in cosmetics and pharmaceuticals, ensuring the stability and hygiene of formulations by inhibiting microbial growth. The mechanism of action involves disrupting bacterial cell walls or interfering with cellular metabolism, making biguanides effective against various microorganisms while being generally safe for human use.
