Triclosán is an antibacterial and antifungal agent commonly found in various personal care products, such as soaps, toothpaste, and deodorants. It works by inhibiting the growth of bacteria and fungi, helping to reduce infections and maintain hygiene. However, concerns have been raised about the safety and environmental impact of triclosán. Studies suggest that it may contribute to antibiotic resistance and can disrupt endocrine function in humans and wildlife. As a result, some countries have restricted its use in consumer products, prompting manufacturers to seek alternative ingredients.
